Android仿微信滑动弹出编辑、删除菜单效果、增加下拉刷新功能

如何为不同的list item呈现不同的菜单，本文实例就为大家介绍了Android仿微信或QQ滑动弹出编辑、删除菜单效果、增加下拉刷新等功能的实现，分享给大家供大家参考，具体内容如下

效果图：

1. 下载开源项目，并将其中的liberary导入到自己的项目中：

2. 使用SwipeMenuListView代替ListView，在页面中布局：

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

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

</android.support.v4.widget.SwipeRefreshLayout>

注： SwipeRefreshLayout主要是为了给该列表增加下拉刷新功能！

3. 为该ListView创建适配器，与正常的实现并无二致：

public class MusicAdapter extends BaseAdapter { 

 private List<Music> mDatas; 

 private Context mContext; 

 public MusicAdapter(List<Music> mDatas, Context mContext) {
  this.mDatas = mDatas;
  this.mContext = mContext;
 } 

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

 @Override
 public Music getItem(int position) {
  return mDatas.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(mContext, R.layout.list_item_music, null);
   new ViewHolder(convertView);
  } 

  ViewHolder holder = (ViewHolder) convertView.getTag(); 

  Music music = mDatas.get(position); 

  holder.textTitle.setText(music.title);
  holder.textDesc.setText(music.desc); 

  return convertView;
 } 

 class ViewHolder {
  TextView textTitle;
  TextView textDesc; 

  public ViewHolder(View view) {
   textTitle = (TextView) view.findViewById(R.id.textTitle);
   textDesc = (TextView) view.findViewById(R.id.textDesc);
   view.setTag(this);
  }
 }
}

4. 为SwipeMenuListView实现Adapter，并在之后，创建滑动菜单：

public class MainActivity extends AppCompatActivity { 

 @ViewInject(R.id.listViewMusic)
 private SwipeMenuListView listViewMusic; 

 @ViewInject(R.id.swipeRefreshMusic)
 private SwipeRefreshLayout swipeRefreshMusic; 

 private List<Music> musics; 

 private MusicAdapter musicAdapter; 

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

  x.view().inject(this);
  musics = new ArrayList<>(); 

  for (int i = 0; i < 4; i++) { 

   Music music = new Music();
   music.title = "上邪 : " + i;
   music.desc = "我欲与君相知，长命无绝衰";
   musics.add(music);
  } 

  musicAdapter = new MusicAdapter(musics, this);
  listViewMusic.setAdapter(musicAdapter); 

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

    // create "edit" item
    SwipeMenuItem deleteItem = new SwipeMenuItem(
      getApplicationContext());
    // set item background
    deleteItem.setBackground(new ColorDrawable(Color.parseColor("#ff0000")));
    // set item width
    deleteItem.setWidth(dp2px(90));
    // set item title
    deleteItem.setTitle("删除");
    // set item title fontsize
    deleteItem.setTitleSize(18);
    // set item title font color
    deleteItem.setTitleColor(Color.WHITE);
    // add to menu
    menu.addMenuItem(deleteItem);
   }
  }; 

  listViewMusic.setMenuCreator(swipeMenuCreator); 

  listViewMusic.setOnMenuItemClickListener(new SwipeMenuListView.OnMenuItemClickListener() {
   @Override
   public boolean onMenuItemClick(int position, SwipeMenu menu, int index) {
    switch (index) {// index即是操作menu添加的顺序
     case 0:
      Toast.makeText(MainActivity.this, "编辑 : " + position, Toast.LENGTH_SHORT).show();
      break;
     case 1:
      Toast.makeText(MainActivity.this, "删除 : " + position, Toast.LENGTH_SHORT).show();
      musics.remove(position);
      musicAdapter.notifyDataSetChanged();
      break;
    } 

    return false;
   }
  }); 

  swipeRefreshMusic.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
   @Override
   public void onRefresh() { 

    swipeRefreshMusic.setRefreshing(true);
    new Handler().postDelayed(new Runnable() {
     @Override
     public void run() { 

      for (int i = 0; i < 4; i++) { 

       Music music = new Music();
       music.title = "无缘 : " + i;
       music.desc = "风雨千山玉独行，天下倾心叹无缘";
       musics.add(music);
      }
      musicAdapter.notifyDataSetChanged(); 

      swipeRefreshMusic.setRefreshing(false);
     }
    }, 2000); 

   }
  });
 } 

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

注： 
  1. SwipeMenuCreator是为了给该listitem创建菜单使用，需要实现该的接口中的create方法，在该方法中，可以自由创建菜单项，比如删除、编辑，可以设置菜单的背景颜色，字体颜色大小等；
  2. 在创建SwipeMenuCreator实例后，需为列表设置菜单：listViewMusic.setMenuCreator(swipeMenuCreator);
  3. 通过设置SwipeMenuListView的setOnMenuItemClickListener方法，监听菜单的点击事件，通过onMenuItemClick(int position, SwipeMenu menu, int index)方法，对菜单事件进行处理；
  4. 通过设置SwipeMenuListView的setOnRefreshListener方法，为菜单添加下拉刷新功能！
