Android 高仿微信(QQ)滑动弹出编辑、删除菜单效果,增加下拉刷新功能

不可否认,微信、QQ列表的滑动删除、编辑功能着实很经典(从IOS那边模仿过来的),然、Android这边,对列表的操作,其实大多还停留上下文菜单来实现。

Android如何实现list item的滑动呢?介绍一个很简单实用的开源项目:

https://github.com/baoyongzhang/SwipeMenuListView

使用该开源项目,我们只需要很简单的一些逻辑,就可以实现滑动菜单功能了!先看下效果图:

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*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!

如此这般,便可完美的实现的list item滑动编辑删除功能啦,欢迎指正!
