Github上的Android项目介绍之ListViewAnimation（针对listView item的侧滑菜单）（1）

demo源码，需要可以下载

1.这是一个github开源项目，先去github上面下载，github下载地址。

2.将SwipeMenuListView项目，导入，然后新建项目如果要引用，要设置为相应的lid应用，如图勾选。


3.activity_main.xml 的布局文件代码：

<com.baoyz.swipemenulistview.SwipeMenuListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent" />

主要是加入这个控件。

4.item_list_app.xml布局文件，代码如下：

<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="wrap_content"
android:padding="8dp" >

<ImageView
android:id="@+id/iv_icon"
android:layout_width="50dp"
android:layout_height="50dp"
android:src="@drawable/ic_launcher" />

<TextView
android:id="@+id/tv_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:layout_toRightOf="@+id/iv_icon"
android:text="name"
android:textColor="@android:color/black"
android:textSize="18sp" />

</RelativeLayout>

5.加入ic_delete.png图片。

6.定义扩展自BaseAdapter的adapter，用来提供列表数据。

同时重写swipeMenu的回调方法，主要是实现SwipeMenuCreator 这个类的create（）方法，和相应的OnMenuItemClickListener接口。至于数据来源则是List类型的，是由 getPackageManager().getInstalledApplications(0); 方法获得。

如果要重用这个代码，需要实现SwipeMenuCreator 类和相应的OnMenuItemClickListener接口。

主要代码如下：

public class MainActivity extends Activity {

private List<ApplicationInfo> mAppList;
private AppAdapter mAdapter;
private SwipeMenuListView mListView;

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

mAppList = getPackageManager().getInstalledApplications(0);

mListView = (SwipeMenuListView) findViewById(R.id.listView);
mAdapter = new AppAdapter();
mListView.setAdapter(mAdapter);

SwipeMenuCreator creator = new SwipeMenuCreator() {

@Override
public void create(SwipeMenu menu) {
// create "open" item
SwipeMenuItem openItem = new SwipeMenuItem(
getApplicationContext());
// set item background
openItem.setBackground(new ColorDrawable(Color.rgb(0xC9, 0xC9,
0xCE)));
// set item width
openItem.setWidth(dp2px(90));
// set item title
openItem.setTitle("Open");
// set item title fontsize
openItem.setTitleSize(18);
// set item title font color
openItem.setTitleColor(Color.WHITE);
// add to menu
menu.addMenuItem(openItem);

// create "delete" item
SwipeMenuItem deleteItem = new SwipeMenuItem(
getApplicationContext());
// set item background
deleteItem.setBackground(new ColorDrawable(Color.rgb(0xF9,
0x3F, 0x25)));
// set item width
deleteItem.setWidth(dp2px(90));
// set a icon
deleteItem.setIcon(R.drawable.ic_delete);
// add to menu
menu.addMenuItem(deleteItem);
}
};

// set creator
mListView.setMenuCreator(creator);

mListView.setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(int position, SwipeMenu menu, int index) {
switch (index) {
case 0:
// open
Toast.makeText(getApplicationContext(), "Open", Toast.LENGTH_SHORT).show();
break;
case 1:
// delete
Toast.makeText(getApplicationContext(), "Delete", Toast.LENGTH_SHORT).show();
//                  mAppList.remove(position);
//                  mAdapter.notifyDataSetChanged();
break;
}
// false : close the menu; true : not close the menu
return false;
}
});

}
class AppAdapter extends BaseAdapter {

@Override
public int getCount() {
return mAppList.size();
}

@Override
public ApplicationInfo getItem(int position) {
return mAppList.get(position);
}

@Override
public long getItemId(int position) {
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = View.inflate(getApplicationContext(),
R.layout.item_list_app, null);
new ViewHolder(convertView);
}
ViewHolder holder = (ViewHolder) convertView.getTag();
ApplicationInfo item = getItem(position);
holder.iv_icon.setImageDrawable(item.loadIcon(getPackageManager()));
holder.tv_name.setText(item.loadLabel(getPackageManager()));
return convertView;
}

class ViewHolder {
ImageView iv_icon;
TextView tv_name;

public ViewHolder(View view) {
iv_icon = (ImageView) view.findViewById(R.id.iv_icon);
tv_name = (TextView) view.findViewById(R.id.tv_name);
view.setTag(this);
}
}
}

private int dp2px(int dp) {
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp,
getResources().getDisplayMetrics());
}
}

。
