android项目添加activity右滑退出.返回的效果

项目第一版马上就要上线了，产品忽然要添加activity右滑返回上一页的效果，瞬间头大，但查了博客整理了思路，决定用一个比较老的框架：SlidingMenu

实现步骤：

一：先添加依赖。这个是用方法有三种，具体的自己百度。我用的是导入依赖

1.gradle的dependencies里添加
`compile project(":SlidingLibrary")`
2.导入SlidingMenu，new ->import module ->选择下载的SlidingMenu
3.同步

二: 引入到项目中，因为我的要实现全局效果，所以我就添加到BaseActivity里面了，代码如下：

@Override
protected void onCreate(Bundle savedInstanceState) {
//TODO 侧滑
initslide(savedInstanceState);

super.onCreate(savedInstanceState);

private void initslide(Bundle savedInstanceState) {
mHelper = new SlidingActivityHelper(this);
mHelper.onCreate(savedInstanceState);

//这里借用了SlidingMenu的setBehindContentView方法来设置一个透明菜单
View behindView = new View(this);
behindView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
behindView.setBackgroundColor(getResources().getColor(android.R.color.transparent));
setBehindContentView(behindView);

mSlidingMenu = getSlidingMenu();
//设置阴影宽度为10个px
mSlidingMenu.setShadowWidth(10);
//设置阴影
mSlidingMenu.setShadowDrawable(R.drawable.slide_shadow);
//设置下面的布局，也就是我们上面定义的透明菜单离右边屏幕边缘的距离为0，也就是滑动开以后菜单会全屏幕显示
mSlidingMenu.setBehindOffset(0);
mSlidingMenu.setFadeDegree(0.35f);
//菜单打开监听，因为菜单打开后我们要finish掉当前的Activity
mSlidingMenu.setOnOpenedListener(this);

//设置手势滑动方向，因为我们要实现微信那种右滑动的效果，这里设置成SlidingMenu.LEFT模式
mSlidingMenu.setMode(SlidingMenu.LEFT);
//因为微信是只有边缘滑动，我们设置成TOUCHMODE_MARGIN模式，如果你想要全屏幕滑动，只需要把这个改成TOUCHMODE_FULLSCREEN就OK了
mSlidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);

}

注：下面方法有的没用到，根据自己需求来

private SlidingActivityHelper mHelper;
//SlidingMenu
private SlidingMenu mSlidingMenu;

@Override
public void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mHelper.onPostCreate(savedInstanceState);

}

@Override
public boolean onSupportNavigateUp() {
return true;
}

@Override
public View findViewById(int id) {
View v = super.findViewById(id);
if (v != null)
return v;
return mHelper.findViewById(id);
}

@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mHelper.onSaveInstanceState(outState);
}

@Override
public void setContentView(int id) {
setContentView(getLayoutInflater().inflate(id, null));
}

@Override
public void setContentView(View v) {
setContentView(v, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
}

@Override
public void setContentView(View v, ViewGroup.LayoutParams params) {
super.setContentView(v, params);
mHelper.registerAboveContentView(v, params);
}

public void setBehindContentView(int id) {
setBehindContentView(getLayoutInflater().inflate(id, null));
}

public void setBehindContentView(View v) {
setBehindContentView(v, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
}

public void setBehindContentView(View v, ViewGroup.LayoutParams params) {
mHelper.setBehindContentView(v, params);
}

public SlidingMenu getSlidingMenu() {
return mHelper.getSlidingMenu();
}

public void toggle() {
mHelper.toggle();
}

public void showContent() {
mHelper.showContent();
}

public void showMenu() {
mHelper.showMenu();
}

public void showSecondaryMenu() {
mHelper.showSecondaryMenu();
}

public void setSlidingActionBarEnabled(boolean b) {
mHelper.setSlidingActionBarEnabled(b);
}

@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
boolean b = mHelper.onKeyUp(keyCode, event);
if (b) return b;
return super.onKeyUp(keyCode, event);
}

//滑动完全打开菜单后结束掉当前的Activity
@Override
public void onOpened() {
this.finish();
}

别忘了Activity还要实现接口：

public abstract class BaseActivity extends AppCompatActivity implements   SlidingMenu.OnOpenedListener{

三： 设置主题为透明，及划入滑出动画，因为我要实现全局有侧滑效果，所以添加全局主题为透明

<application
android:name=".conifg.MvpContactApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/Base.AppTheme">

<style name="Base.AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/transparent</item>
<item name="colorPrimaryDark">@color/transparent</item>
<item name="colorAccent">@color/colorAccent</item>
<!-- 以下为实现侧滑相关item  -->
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowAnimationStyle">@style/JK.Animation.SlidingBack</item>
<item name="android:actionBarStyle">@style/JKActionBar.Custom</item>
</style>

<style name="JK.Animation.SlidingBack" parent="@android:style/Animation.Activity">
<item name="android:activityOpenEnterAnimation">@anim/slide_in_right</item>
<item name="android:activityOpenExitAnimation">@anim/slide_out_right</item>
<item name="android:activityCloseEnterAnimation">@anim/slide_in_right</item>
<item name="android:activityCloseExitAnimation">@anim/slide_out_right</item>
<item name="android:wallpaperOpenEnterAnimation">@anim/slide_in_right</item>
<item name="android:wallpaperOpenExitAnimation">@anim/slide_out_right</item>
<item name="android:wallpaperCloseEnterAnimation">@anim/slide_in_right</item>
<item name="android:wallpaperCloseExitAnimation">@anim/slide_out_right</item>
<item name="android:wallpaperIntraOpenEnterAnimation">@anim/slide_in_right</item>
<item name="android:wallpaperIntraOpenExitAnimation">@anim/slide_out_right</item>
<item name="android:wallpaperIntraCloseEnterAnimation">@anim/slide_in_right</item>
<item name="android:wallpaperIntraCloseExitAnimation">@anim/slide_out_right</item>
</style>

<style name="JKActionBar.Custom"      parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="displayOptions">showCustom</item>
<item name="android:background">@android:color/holo_blue_bright</item>
<item name="background">@android:color/transparent</item>
<item name="android:displayOptions" tools:ignore="NewApi">showCustom</item>
<item name="android:height">?actionBarSize</item>
</style>

恩，现在运行应该就可以出现效果了，但是在我项目中有的还要实现沉浸式状态栏效果，比如启动页那样的效果我也没找到方案，所以就没有继承baseActivity。而因为已经把状态栏也设置为透明的，所以有时会出现显示下层页面状态栏的问题，so 在BaseActivity的oncreate的里面添加

//TODO 这句话貌似应该放在setContentView(getLayoutId());的下面
setWindowStatusBarColor(this.mActivity,R.color.black);      //实现状态栏黑色

public void setWindowStatusBarColor(Activity activity, int colorResId) {
try {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = activity.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(activity.getResources().getColor(colorResId));
}
} catch (Exception e) {
e.printStackTrace();
}
}

**另外: 如果想让布局顶上状态栏实现沉浸式，可以在oncreat（）方法里加上**

//TODO 下面这个判断如果不加沉浸式无法实现，设置slidemenu的mActionbarOverlay = true也没用
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {//5.0及以上
View decorView = getWindow().getDecorView();
int option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE;
decorView.setSystemUiVisibility(option);
getWindow().setStatusBarColor(Color.TRANSPARENT);
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {//4.4到5.0
WindowManager.LayoutParams localLayoutParams = getWindow().getAttributes();
localLayoutParams.flags = (WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | localLayoutParams.flags);
}

并且把SlidingActivityHelper类中onPostCreate方法的

mSlidingMenu.attachToActivity(mActivity,
mEnableSlide ? SlidingMenu.SLIDING_WINDOW : SlidingMenu.SLIDING_CONTENT);

替换成

mEnableSlide=false;
this.mSlidingMenu.attachToActivity(this.mActivity, this.mEnableSlide ? 0 : 1, true);

研究源码可知mActionbarOverlay为true时才会触发 android:fitsSystemWindows="true"的效果

对于SlidingMenu的使用暂时先写这么多，至于demo源码有时间了再写
