Android使用SwipeListView实现类似QQ的滑动删除效果

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, boolean right) 
      { 
        log.d(tag, "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：
