3.主题切换-MainActivity

[java] view plain copy print?@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//获取主题ID，设置主题
int themeId = getIntent().getIntExtra(“themeId”, -1);
if (themeId != -1) {
setTheme(themeId);
}
setContentView(R.layout.activity_main);
}
//设置主题必须在setContentView之前使用，所以要重启自己
public void red(View v) {
//结束自己
finish();
//不用动画
overridePendingTransition(0, 0);//紧挨着finish方法或者对应的startActivity方法就可以
//重启自己
Intent intent = new Intent(MainActivity.this, MainActivity.class);
//告知需要切换的主题
intent.putExtra(”themeId”, R.style.AppTheme_Red);
startActivity(intent);
overridePendingTransition(0, 0);//紧挨着finish方法或者对应的startActivity方法就可以
}

public void pink(View v) {
finish();
overridePendingTransition(0, 0);//紧挨着finish方法或者对应的startActivity方法就可以
//重启自己
Intent intent = new Intent(MainActivity.this, MainActivity.class);
//告知需要切换的主题
intent.putExtra(”themeId”, R.style.AppTheme_Pink);
startActivity(intent);
overridePendingTransition(0, 0);//紧挨着finish方法或者对应的startActivity方法就可以
}

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//获取主题ID，设置主题
int themeId = getIntent().getIntExtra("themeId", -1);
if (themeId != -1) {
setTheme(themeId);
}
setContentView(R.layout.activity_main);
}
//设置主题必须在setContentView之前使用，所以要重启自己
public void red(View v) {
//结束自己
finish();
//不用动画
overridePendingTransition(0, 0);//紧挨着finish方法或者对应的startActivity方法就可以
//重启自己
Intent intent = new Intent(MainActivity.this, MainActivity.class);
//告知需要切换的主题
intent.putExtra("themeId", R.style.AppTheme_Red);
startActivity(intent);
overridePendingTransition(0, 0);//紧挨着finish方法或者对应的startActivity方法就可以
}

public void pink(View v) {
finish();
overridePendingTransition(0, 0);//紧挨着finish方法或者对应的startActivity方法就可以
//重启自己
Intent intent = new Intent(MainActivity.this, MainActivity.class);
//告知需要切换的主题
intent.putExtra("themeId", R.style.AppTheme_Pink);
startActivity(intent);
overridePendingTransition(0, 0);//紧挨着finish方法或者对应的startActivity方法就可以
}

5.主题不仅可以对Application和Activity使用，也可以对某一个控件单使用，或者是在xml布局中给一个根节点控件设置android:theme属性，来修改它和它所有子控件的主题。

6.Material Design主题只有在API级别为21以上才可使用，在v7支持库中提供了部分控件的Material Design主题样式，如果想使应用在android的所有版本上都能统一风格，我们可以对控件效果做自定义或者使用一些第三方的兼容包。目前最有效的做法是针对21版本创建value－21资源目录，使用Material Design风格主题，在其他版本使用v7的Theme.AppCompat.Light风格主题。

7.项目中使用Material Design风格

1. 设置应用的 `targetSdkVersion` 和 `targetSdkVersion` 为21

2. 在values目录下的style资源文件中创建一个style，让其继承自 `android:Theme.Material`

3. 在AndroidManifest中指定应用的主题或者Activity的主题为我们设定的样式

9.toolBar的使用

1.toolBar

Toolbar是应用的内容的标准工具栏，`可以说是Actionbar的升级版`，两者不是独立关系，要使用Toolbar还是得跟ActionBar扯上关系的。相比Actionbar Toolbar最明显的一点就是变得很`自由，可随处放置`，因为它是作为一个`ViewGroup来定义使用的`，所以单纯使用ActionBar已经稍显过时了，它的一些方法已被标注过时。

2.引入v7,v4包,修改build.gradle，兼容2.2

(1)引入v7包,去除actionBar value

[html] view plain copy print?<style name=“AppTheme” parent=“Theme.AppCompat.Light.NoActionBar”>
<!– Customize your theme here. –>
</style>

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
</style>

(2)创建ToolBar的布局 include_toolbar.xml

[html] view plain copy print?<?xml version=“1.0” encoding=“utf-8”?>
<android.support.v7.widget.Toolbar
xmlns:android=“http://schemas.android.com/apk/res/android”
android:layout_width=“match_parent”
android:layout_height=“wrap_content”
android:background=“#ff0000”>

</android.support.v7.widget.Toolbar>

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff0000">

</android.support.v7.widget.Toolbar>

(3)使用toolbar

a.布局中

[html] view plain copy print?<include layout=“@layout/include_toolbar”></include>

<include layout="@layout/include_toolbar"></include>

b.代码

[java] view plain copy print?/** * 1.需要继承我们的actionBarActivity */ public class MainActivity extends ActionBarActivity { private Toolbar mToolbar; private DrawerLayout mDrawerLayout; private ActionBarDrawerToggle mToggle; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); } private void initView() { mToolbar = (Toolbar) findViewById(R.id.main_toolbar); //Set a Toolbar to act as the ActionBar for this Activity window. setSupportActionBar(mToolbar); }

/**
* 1.需要继承我们的actionBarActivity
*/
public class MainActivity extends ActionBarActivity {

private Toolbar mToolbar;
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
}
private void initView() {
mToolbar = (Toolbar) findViewById(R.id.main_toolbar);

//Set a Toolbar to act as the ActionBar for this Activity window.
setSupportActionBar(mToolbar);

}

10.drawerlayout和actionbardrawertoggle的集成

1.接上

2.布局

3.MainActivity

[java] view plain copy print?/** * 1.需要继承我们的actionBarActivity */ public class MainActivity extends ActionBarActivity { private Toolbar mToolbar; private DrawerLayout mDrawerLayout; private ActionBarDrawerToggle mToggle; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); initDrawerLayout(); } private void initDrawerLayout() { mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R .string.open, R.string.close); //同步状态 mToggle.syncState(); //设置监听 mDrawerLayout.setDrawerListener(mToggle); } private void initView() { mToolbar = (Toolbar) findViewById(R.id.main_toolbar); //Set a Toolbar to act as the ActionBar for this Activity window. setSupportActionBar(mToolbar); mDrawerLayout = (DrawerLayout) findViewById(R.id.main_drawerlayout); }

/**
* 1.需要继承我们的actionBarActivity
*/
public class MainActivity extends ActionBarActivity {

private Toolbar mToolbar;
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
initDrawerLayout();
}

private void initDrawerLayout() {
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R
.string.open, R.string.close);

//同步状态
mToggle.syncState();

//设置监听
mDrawerLayout.setDrawerListener(mToggle);
}

private void initView() {
mToolbar = (Toolbar) findViewById(R.id.main_toolbar);

//Set a Toolbar to act as the ActionBar for this Activity window.
setSupportActionBar(mToolbar);

mDrawerLayout = (DrawerLayout) findViewById(R.id.main_drawerlayout);
}

11.阴影和裁剪效果

1.布局

[html] view plain copy print?<RelativeLayout xmlns:android=“http://schemas.android.com/apk/res/android”
xmlns:tools=“http://schemas.android.com/tools”
android:layout_width=“match_parent”
android:layout_height=“match_parent”
android:background=“#ffffff”
android:paddingBottom=“@dimen/activity_vertical_margin”
android:paddingLeft=“@dimen/activity_horizontal_margin”
android:paddingRight=“@dimen/activity_horizontal_margin”
android:paddingTop=“@dimen/activity_vertical_margin”
tools:context=“.MainActivity”>

<!–红色–>
<View
android:layout_width=“100dp”
android:layout_height=“100dp”
android:layout_margin=“10dp”
android:background=“#ff0000”
android:elevation=“11dp”/>
<!–绿色–>
<View
android:layout_width=“100dp”
android:layout_height=“100dp”
android:layout_marginLeft=“60dp”
android:layout_marginTop=“60dp”
android:background=“#00ff00”
android:elevation=“10dp”/>
<!–圆形的shape–>
<View
android:layout_width=“100dp”
android:layout_height=“100dp”
android:layout_marginLeft=“180dp”
android:layout_marginTop=“180dp”
android:background=“@drawable/shape_circle”
android:elevation=“10dp”/>
<!–圆形的图片–>
<View

android:id=“@+id/ivHead”
android:layout_width=“100dp”
android:layout_height=“100dp”
android:layout_marginLeft=“180dp”
android:layout_marginTop=“300dp”
android:background=“@mipmap/head”
android:elevation=“10dp”/>
</RelativeLayout>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity">

<!--红色-->
<View
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_margin="10dp"
android:background="#ff0000"
android:elevation="11dp"/>
<!--绿色-->
<View
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_marginLeft="60dp"
android:layout_marginTop="60dp"
android:background="#00ff00"
android:elevation="10dp"/>
<!--圆形的shape-->
<View
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_marginLeft="180dp"
android:layout_marginTop="180dp"
android:background="@drawable/shape_circle"
android:elevation="10dp"/>
<!--圆形的图片-->
<View

android:id="@+id/ivHead"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_marginLeft="180dp"
android:layout_marginTop="300dp"
android:background="@mipmap/head"
android:elevation="10dp"/>
</RelativeLayout>

2.在xml布局中，可以通过android:outlineProvider来指定轮廓的判定方式：

(1)none 即使设置了Z属性，也不会显示阴影

(2)background 会按照背景来设置阴影形状

(3)bounds 会按照View的大小来描绘阴影

(4)paddedBounds 和bounds类似，不过阴影会稍微向右偏移一点

3. 在代码中，我们可以通过setOutlineProvider来指定一个View的轮廓：

[html] view plain copy print?ViewOutlineProvider viewOutlineProvider = new ViewOutlineProvider() { public void getOutline(View view, Outline outline) { // 可以指定圆形，矩形，圆角矩形，path outline.setOval(0, 0, view.getWidth(), view.getHeight()); } }; View.setOutlineProvider(viewOutlineProvider );

ViewOutlineProvider viewOutlineProvider = new ViewOutlineProvider() {
public void getOutline(View view, Outline outline) {
// 可以指定圆形，矩形，圆角矩形，path
outline.setOval(0, 0, view.getWidth(), view.getHeight());
}
};
View.setOutlineProvider(viewOutlineProvider );

4.注意：如果采用图片作为背景，即使在xml布局中指定android:outlineProvider为background也不会显示阴影，只有通过代码中指定轮廓来显示。

5.MainActivity

[java] view plain copy print?private View mIvHead;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mIvHead = (View) findViewById(R.id.ivHead);
//设置轮廓
mIvHead.setOutlineProvider(new ViewOutlineProvider() {
@Override
public void getOutline(View view, Outline outline) {
//设置view对应的轮廓
outline.setOval(0, 0, view.getWidth() - 20, view.getHeight() - 20);
}
});
mIvHead.setClipToOutline(true);
}

private View mIvHead;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mIvHead = (View) findViewById(R.id.ivHead);
//设置轮廓
mIvHead.setOutlineProvider(new ViewOutlineProvider() {
@Override
public void getOutline(View view, Outline outline) {
//设置view对应的轮廓
outline.setOval(0, 0, view.getWidth() - 20, view.getHeight() - 20);
}
});
mIvHead.setClipToOutline(true);
}

12.selector定义新方式

1.tint属性

tint属性一个颜色值，可以对图片做颜色渲染，我们可以给view的背景设置tint色值，给ImageView的图片设置tint色值，也可以给任意Drawable或者NinePatchDrawable设置tint色值。

在应用的主题中也可以通过设置 android:tint来给主题设置统一的颜色渲染。

tint的渲染模式有总共有16种，xml文件中可以使用6种，代码中我们可以设置16种，渲染模式决定了渲染颜色和原图颜色的取舍和合成规则：———–两种图片合成的效果

PorterDuff.Mode.CLEAR

所绘制不会提交到画布上。

PorterDuff.Mode.SRC

显示上层绘制图片

PorterDuff.Mode.DST

显示下层绘制图片

PorterDuff.Mode.SRC_OVER

正常绘制显示，上下层绘制叠盖。

PorterDuff.Mode.DST_OVER

上下层都显示。下层居上显示。

取下层非交集部分与上层交集部分

PorterDuff.Mode.DST_ATOP

取上层非交集部分与下层交集部分

PorterDuff.Mode.XOR

取两层绘制非交集。两层绘制非交集。

PorterDuff.Mode.DARKEN

上下层都显示。变暗

PorterDuff.Mode.LIGHTEN

上下层都显示。变亮

PorterDuff.Mode.MULTIPLY

取两层绘制交集

PorterDuff.Mode.SCREEN

13.Palette调色版功能

1.Android Material Design之Toolbar与Palette实践:http://blog.csdn.net/jdsjlzx/article/details/41441083

2.需要导入相关的包：v7和

3.

[java] view plain copy print?private void initView() {
mIv_muted = findViewById(R.id.iv_Muted);
mIv_muted_light = findViewById(R.id.iv_Muted_light);
mIv_vibrant = findViewById(R.id.iv_Vibrant);
}

public void click(View v) {
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.h17);
// 如果操作本来就属于后台线程，可以使用：
// Palette p = Palette.generate(bitmap);
// 如果在主线程中，我们可以使用异步的方式：
Palette.generateAsync(bitmap, new Palette.PaletteAsyncListener() {
public void onGenerated(Palette palette) {
mIv_muted.setBackgroundColor(palette.getMutedColor(Color.BLACK));
mIv_muted_light.setBackgroundColor(palette.getLightMutedColor(Color.BLACK));
mIv_vibrant.setBackgroundColor(palette.getVibrantColor(Color.BLACK));
}
});
}

private void initView() {
mIv_muted = findViewById(R.id.iv_Muted);
mIv_muted_light = findViewById(R.id.iv_Muted_light);
mIv_vibrant = findViewById(R.id.iv_Vibrant);
}

public void click(View v) {
Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.h17);
//        如果操作本来就属于后台线程，可以使用：
//        Palette p = Palette.generate(bitmap);
//        如果在主线程中，我们可以使用异步的方式：
Palette.generateAsync(bitmap, new Palette.PaletteAsyncListener() {
public void onGenerated(Palette palette) {
mIv_muted.setBackgroundColor(palette.getMutedColor(Color.BLACK));
mIv_muted_light.setBackgroundColor(palette.getLightMutedColor(Color.BLACK));
mIv_vibrant.setBackgroundColor(palette.getVibrantColor(Color.BLACK));
}
});
}

4.详情见图片和颜色.html

5.

Vibrant

鲜艳的

Vibrant

dark鲜艳的暗色

Vibrant

light鲜艳的亮色

Muted

柔和的

Muted

dark柔和的暗色

Muted

light柔和的亮色

6.对图片取色是一个比较消耗性能的操作，其内部会对图片的像素值进来遍历以分析对比，所以我们要在异步线程中去完成。

7.

p.getVibrantColor(int defaultColor);
p.getDarkVibrantColor(int defaultColor);
p.getLightVibrantColor(int defaultColor);

17.瀑布流的实现

1.接上

2.item布局

[html] view plain copy print?<RelativeLayout
android:layout_width=“match_parent”
android:layout_height=“wrap_content”
android:padding=“5dp”>

<ImageView
android:id=“@+id/item_straggered_iv”

3.StraggerAdapter.Java

[java] view plain copy print?public class StraggerAdapter extends RecyclerView.Adapter<StraggerAdapter.MyHolder> { private Context context; private List<DataBean> datas; public StraggerAdapter(Context context, List<DataBean> datas) { this.context = context; this.datas = datas; } @Override public MyHolder onCreateViewHolder(ViewGroup viewGroup, int i) {//决定根布局 // TextView tv = new TextView(context);//根布局 View itemView = View.inflate(context, R.layout.item_stragger, null); return new MyHolder(itemView); } @Override public void onBindViewHolder(MyHolder myHolder, int position) {//填充数据 myHolder.setDataAndRefreshUI(datas.get(position)); } @Override public int getItemCount() {//条目总数 if (datas != null) { return datas.size(); } return 0; } public class MyHolder extends RecyclerView.ViewHolder { //孩子对象 private TextView mTvName; private ImageView mIvIcon; public MyHolder(View itemView) { super(itemView); //初始化孩子对象 mTvName = (TextView) itemView.findViewById(R.id.item_straggered_tv); mIvIcon = (ImageView) itemView.findViewById(R.id.item_straggered_iv); } /** * 设置itemView的数据展示 * * @param dataBean */ public void setDataAndRefreshUI(DataBean dataBean) { mTvName.setText(dataBean.text); mIvIcon.setImageResource(dataBean.iconId); } } }

public class StraggerAdapter extends RecyclerView.Adapter<StraggerAdapter.MyHolder> {
private Context context;
private List<DataBean> datas;

public StraggerAdapter(Context context, List<DataBean> datas) {
this.context = context;
this.datas = datas;
}

@Override
public MyHolder onCreateViewHolder(ViewGroup viewGroup, int i) {//决定根布局
//        TextView tv = new TextView(context);//根布局
View itemView = View.inflate(context, R.layout.item_stragger, null);
return new MyHolder(itemView);
}

@Override
public void onBindViewHolder(MyHolder myHolder, int position) {//填充数据
myHolder.setDataAndRefreshUI(datas.get(position));
}

@Override
public int getItemCount() {//条目总数
if (datas != null) {
return datas.size();
}
return 0;
}

public class MyHolder extends RecyclerView.ViewHolder {
//孩子对象
private TextView mTvName;
private ImageView mIvIcon;

public MyHolder(View itemView) {
super(itemView);
//初始化孩子对象
mTvName = (TextView) itemView.findViewById(R.id.item_straggered_tv);
mIvIcon = (ImageView) itemView.findViewById(R.id.item_straggered_iv);
}

/**
* 设置itemView的数据展示
*
* @param dataBean
*/
public void setDataAndRefreshUI(DataBean dataBean) {
mTvName.setText(dataBean.text);
mIvIcon.setImageResource(dataBean.iconId);
}
}
}

4.MainActivity中

[java] view plain copy print?private void initStaggeredGridAdapterV() {
//设置layoutManager
StaggeredGridLayoutManager staggeredGridLayoutManager = new StaggeredGridLayoutManager(2,
StaggeredGridLayoutManager.VERTICAL);
mRecyclerView.setLayoutManager(staggeredGridLayoutManager);

//设置adapter
StraggerAdapter adapter = new StraggerAdapter(MainActivity.this, mStraggerDatas);
mRecyclerView.setAdapter(adapter);
}
瀑布流 上面是纵向瀑布流
private void initStaggeredGridAdapterH() {
//设置layoutManager
StaggeredGridLayoutManager staggeredGridLayoutManager = new StaggeredGridLayoutManager(2,
StaggeredGridLayoutManager.HORIZONTAL);
mRecyclerView.setLayoutManager(staggeredGridLayoutManager);

//设置adapter
StraggerAdapter adapter = new StraggerAdapter(MainActivity.this, mStraggerDatas);
mRecyclerView.setAdapter(adapter);
}

private void initStaggeredGridAdapterV() {
//设置layoutManager
StaggeredGridLayoutManager staggeredGridLayoutManager = new StaggeredGridLayoutManager(2,
StaggeredGridLayoutManager.VERTICAL);
mRecyclerView.setLayoutManager(staggeredGridLayoutManager);

//设置adapter
StraggerAdapter adapter = new StraggerAdapter(MainActivity.this, mStraggerDatas);
mRecyclerView.setAdapter(adapter);
}
//横向瀑布流    上面是纵向瀑布流
private void initStaggeredGridAdapterH() {
//设置layoutManager
StaggeredGridLayoutManager staggeredGridLayoutManager = new StaggeredGridLayoutManager(2,
StaggeredGridLayoutManager.HORIZONTAL);
mRecyclerView.setLayoutManager(staggeredGridLayoutManager);

//设置adapter
StraggerAdapter adapter = new StraggerAdapter(MainActivity.this, mStraggerDatas);
mRecyclerView.setAdapter(adapter);
}

18.cardView引入

1.在cardview独立的包中

2.直接套在布局中

3.可以设置各种属性，圆角，z轴大小…..

19.swiperefreshLayout的使用

1.下拉刷新

2.使用

(1)

[html] view plain copy print?<RelativeLayout xmlns:android=“http://schemas.android.com/apk/res/android”
xmlns:tools=“http://schemas.android.com/tools”
android:layout_width=“match_parent”
android:layout_height=“match_parent”
tools:context=“.MainActivity”>

<android.support.v4.widget.SwipeRefreshLayout
android:id=“@+id/swipeRefreshLayout”
android:layout_width=“match_parent”
android:layout_height=“wrap_content”
>

<android.support.v7.widget.RecyclerView
android:id=“@+id/recyclerView”
android:layout_width=“match_parent”
android:layout_height=“match_parent”
/>
</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/swipeRefreshLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>

<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>

(2)

[java] view plain copy print?private SwipeRefreshLayout mSwipeRefreshLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

//找到recyclerView
mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView);
//下拉刷新控件
mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);

// initData();
//initListAdapterV();

initListener();

}

private void initListener() {
mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
//模拟加载数据
new Thread(new Runnable() {
@Override
public void run() {
SystemClock.sleep(2000);
MainActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
//停止刷新操作
mSwipeRefreshLayout.setRefreshing(false);
//得到adapter.然后刷新
mRecyclerView.getAdapter().notifyDataSetChanged();
}
});

}
}).start();
;
}
});
}

private SwipeRefreshLayout mSwipeRefreshLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

//找到recyclerView
mRecyclerView = (RecyclerView) findViewById(R.id.recyclerView);
//下拉刷新控件
mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);

// initData();
//initListAdapterV();

initListener();

}

private void initListener() {
mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
//模拟加载数据
new Thread(new Runnable() {
@Override
public void run() {
SystemClock.sleep(2000);
MainActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
//停止刷新操作
mSwipeRefreshLayout.setRefreshing(false);
//得到adapter.然后刷新
mRecyclerView.getAdapter().notifyDataSetChanged();
}
});

}
}).start();
;
}
});
}

20.兼容性

1.虽然Material Design新增了许多新特性，但是并不是所有新内容对对下保持了兼容。

2.使用v7包————v7 support libraries r21 及更高版本包含了以下Material Design特性：

(1). 使用Theme.AppCompat主题包含调色板主体属性，可以对应用的主题做统一的配色，但是不包括状态栏和底部操作栏

(2). RecyclerView和CardView被独立出来，只要引入jar包，即可适配7以上的所有版本。

(3). Palette类用于从图片提取主色调

3.系统组件————–Theme.AppCompat主题中提供了这些组件的Material Design style：

(1). EditText

(2). Spinner

(3). CheckBox

(4). RadioButton

(5). SwitchCompat

(6). CheckedTextView

(7). Color Palette

4.以下特性只在Android 5.0 (API level 21) 及以上版本中可用：

(1). 转场动画

(2). 触摸反馈

(3). 圆形展示动画

(4). 路径动画

(5). 矢量图

(6). tint染色

所以在代码中遇上使用这些api的地方需要进行版本判断

[java] view plain copy print?if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
// 使用新特性
} else {
// 用其他替代方式
}

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
// 使用新特性
} else {
// 用其他替代方式
}

5. RippleDrawable 提供触摸反馈特效，即5.0的button按压下的水波纹效果。
