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());      }  }
