QQ的滑动删除效果很不错,要实现这种效果,可以使用SwipeListVIEw。

1. 下载com.fortysevendeg.swipeListvIEw这个项目(以前GitHub上有,现在GitHub上没有了,百度了很多次才下载到的),导入Eclipse,右键单击,选择PropertIEs->AndroID,选中library下面的Islibrary。

2. 新建一个项目MySwipeListVIEw,加入SwipeListVIEw这个库。

3. 在主窗体里面放入一个SwipeListVIEw控件:

<linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"  xmlns:tools="http://schemas.androID.com/tools"  androID:layout_wIDth="match_parent"  androID:layout_height="match_parent"  androID:orIEntation="vertical"  androID:paddingBottom="@dimen/activity_vertical_margin"  androID:paddingleft="@dimen/activity_horizontal_margin"  androID:paddingRight="@dimen/activity_horizontal_margin"  androID:paddingtop="@dimen/activity_vertical_margin"  tools:context="com.hzhi.myswipeListvIEw.MainActivity" >      <com.fortysevendeg.swipeListvIEw.SwipeListVIEw      xmlns:swipe="http://schemas.androID.com/apk/res-auto"      androID:ID="@+ID/exampleSwipeListVIEw"      androID:ListSelector="#00000000"      androID:layout_wIDth="fill_parent"      androID:layout_height="wrap_content"      swipe:swipeBackVIEw="@+ID/back"      swipe:swipeCloseAllitemsWhenMoveList="true"      swipe:swipeDrawableChecked="@drawable/choice_selected"      swipe:swipeDrawableunchecked="@drawable/choice_unselected"      swipe:swipeFrontVIEw="@+ID/front"      swipe:swipeMode="both"       swipe:swipeActionleft="reveal"      swipe:swipeActionRight="dismiss"      swipe:swipeOpenOnLongPress="true"    /></linearLayout>

其中两个重要的属性:
swipe:swipeFrontVIEw:上面的VIEw,即不滑动时显示的VIEw。
swipe:swipeBackVIEw:下面的VIEw,即滑动后显示的VIEw。
这两个VIEw都定义在SwipeListVIEw的行布局文件里面: 

<?xml version="1.0" enCoding="utf-8"?><FrameLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"       androID:layout_wIDth="fill_parent"       androID:layout_height="fill_parent"    >      <linearLayout    androID:ID="@+ID/back"    androID:layout_wIDth="fill_parent"    androID:layout_height="wrap_content"    androID:background="#ffcccccc"    androID:gravity="right"    androID:tag="back" >    <button        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:ID="@+ID/btn_delete"        androID:text="删除"/>    <button        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:ID="@+ID/btn_update"        androID:text="更新"/>  </linearLayout>  <relativeLayout      androID:orIEntation="vertical"      androID:ID="@+ID/front"      androID:layout_wIDth="fill_parent"      androID:layout_height="wrap_content"      androID:background="#ffffffff"  >    <ImageVIEw        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:ID="@+ID/example_row_iv_image"/>    <TextVIEw        androID:layout_wIDth="fill_parent"        androID:layout_height="wrap_content"        androID:layout_toRightOf="@ID/example_row_iv_image"        androID:ID="@+ID/example_row_tv_Title"/>    <TextVIEw        androID:layout_wIDth="fill_parent"        androID:layout_height="wrap_content"        androID:layout_toRightOf="@ID/example_row_iv_image"        androID:layout_below="@ID/example_row_tv_Title"        androID:ID="@+ID/example_row_tv_description"/>  </relativeLayout>      </FrameLayout>

SwipeListVIEw的行布局文件使用FrameLayout布局,FrameLayout里面所有的所有子元素都堆叠在FrameLayout的左上角。 

4. SwipeListVIEw和其他ListVIEw一样,也需要Adapter,使用方法也是一样的。这里就不详细讲了。 

5. 在主窗体Java文件中实现SwipeListVIEw的功能,代码如下:

package com.hzhi.myswipeListvIEw;import androID.support.v7.app.ActionBaractivity;import androID.util.Log;import java.util.ArrayList;import com.fortysevendeg.swipeListvIEw.BaseSwipeListVIEwListener;import com.fortysevendeg.swipeListvIEw.SwipeListVIEw;import androID.os.Bundle;@SuppressWarnings("deprecation")public class MainActivity extends ActionBaractivity {    protected static final String TAG = "MySwipeListVIEw";   private ArrayList<String> mList;  private MyAdapter mAdapter;  private SwipeListVIEw mSwipeListVIEw;  @OverrIDe  protected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.activity_main);        initData();    mSwipeListVIEw = (SwipeListVIEw) findVIEwByID(R.ID.exampleSwipeListVIEw);    mAdapter = new MyAdapter(this,mList,mSwipeListVIEw);     mSwipeListVIEw.setAdapter(mAdapter);        mSwipeListVIEw.setSwipeListVIEwListener(new BaseSwipeListVIEwListener(){      @OverrIDe       public voID onChoiceChanged(int position,boolean selected)       {         Log.d(TAG,"onChoiceChanged:" + position + "," + selected);       }        @OverrIDe       public voID onChoiceEnded()       {         Log.d(TAG,"onChoiceEnded");       }        @OverrIDe       public voID onChoiceStarted()       {         Log.d(TAG,"onChoiceStarted");       }        @OverrIDe       public voID onClickBackVIEw(int position)       {         Log.d(TAG,"onClickBackVIEw:" + position);       }        @OverrIDe       public voID onClickFrontVIEw(int position)       {         Log.d(TAG,"onClickFrontVIEw:" + position);       }        @OverrIDe       public voID onClosed(int position,boolean fromright)       {         Log.d(TAG,"onClosed:" + position + "," + fromright);       }        @OverrIDe       public voID ondismiss(int[] reverseSortedpositions)       {         Log.d(TAG,"ondismiss");             }        @OverrIDe       public voID onFirstListItem()       {         Log.d(TAG,"onFirstListItem");       }        @OverrIDe       public voID onLastListItem()       {         Log.d(TAG,"onLastListItem");       }        @OverrIDe       public voID onListChanged()       {         Log.d(TAG,"onListChanged");         mSwipeListVIEw.cloSEOpenedItems();        }        @OverrIDe       public voID onMove(int position,float x)       {         Log.d(TAG,"onMove:" + position + "," + x);       }        @OverrIDe       public voID onopened(int position,boolean toRight)       {         Log.d(TAG,"onopened:" + position + "," + toRight);       }        @OverrIDe       public voID onStartClose(int position,boolean right)       {         Log.d(TAG,"onStartClose:" + position + "," + right);       }        @OverrIDe       public voID onStartopen(int position,int action,"onStartopen:" + position + "," + action + "," + right);       }     });      }    private voID initData(){    mList = new ArrayList<String>();     for (int i = 0; i <= 10; i++)       mList.add("这是第" + i +"条数据!");   }  }

最主要的代码即mSwipeListVIEw.setSwipeListVIEwListener(new BaseSwipeListVIEwListener(){}),通过这行代码,为SwipeListVIEw控件设置了Listener,可以根据自己的需要重载BaseSwipeListVIEwListener的各种方法。 

运行结果:
