今天看别人项目，看到别人使用了SwipeListView，Google一把，果然github上的，也参考了csdn上的几篇文章，然后自己写了个例子，分享给大家。

效果图：

嗯，看一眼SwipeListView的参数的设置：

If you decide to use SwipeListView as a view, you can define it in your xml layout like this:

    <com.fortysevendeg.swipelistview.SwipeListView            xmlns:swipe="http://schemas.android.com/apk/res-auto"            android:id="@+id/example_lv_list"            android:listSelector="#00000000"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            swipe:swipeFrontView="@+id/front"            swipe:swipeBackView="@+id/back"            swipe:swipeActionLeft="[reveal | dismiss]"            swipe:swipeActionRight="[reveal | dismiss]"            swipe:swipeMode="[none | both | right | left]"            swipe:swipeCloseAllItemsWhenMoveList="[true | false]"            swipe:swipeOpenOnLongPress="[true | false]"            swipe:swipeAnimationTime="[miliseconds]"            swipe:swipeOffsetLeft="[dimension]"            swipe:swipeOffsetRight="[dimension]"            />

swipeFrontView - Required - front view id. 即ListView Item正常显示的控件Id，且必须与Item的布局文件中的控件id一样
swipeBackView - Required - back view id. 手指滑动时显示的，隐藏在FrontView后面，且必须与item的布局文件中控件Id一样
swipeActionLeft - Optional - left swipe action Default: 'reveal' 左滑的动作，默认reveal，即显示BackView，还有dismiss,choice会触发响应的方法。
swipeActionRight - Optional - right swipe action Default: 'reveal' 同上
swipeMode - Gestures to enable or 'none'. Default: 'both' 设置左滑、右滑、都支持
swipeCloseAllItemsWhenMoveList - Close revealed items on list motion. Default: 'true' 当滚动listview时，关闭所有展开的Item，最好不要设置为false，由于item的复用，false存在一些问题。
swipeOpenOnLongPress - Reveal on long press Default: 'true' 长按时触发显示
swipeAnimationTime - item drop animation time. Default: android configuration 动画时间长度
swipeOffsetLeft - left offset 左偏移量
swipeOffsetRight - right offset 右偏移量

基本属性都介绍了，下面上例子：

1、布局文件

[html] view plaincopy
<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:background="@color/white"  
    android:clickable="true"  
    android:orientation="vertical" xmlns:swipe="http://schemas.android.com/apk/res/com.example.zhy_swipelistview02">  
  
    <include  
        layout="@layout/main_title"  
        android:focusable="true" />  
  
    <FrameLayout  
        android:layout_width="match_parent"  
        android:layout_height="match_parent" >  
  
        <com.fortysevendeg.swipelistview.SwipeListView  
            android:id="@+id/id_swipelistview"  
            android:layout_width="fill_parent"  
            android:layout_height="fill_parent"  
            swipe:swipeActionLeft="reveal"  
            swipe:swipeBackView="@+id/id_back"  
            swipe:swipeCloseAllItemsWhenMoveList="true"  
            swipe:swipeFrontView="@+id/id_front"  
            swipe:swipeMode="left"  
            swipe:swipeOffsetLeft="200dip"  
            swipe:swipeOpenOnLongPress="false" />  
  
        <TextView  
            android:id="@+id/empty"  
            android:layout_width="wrap_content"  
            android:layout_height="wrap_content"  
            android:layout_gravity="center"  
            android:drawableTop="@drawable/no_chat"  
            android:text="木有联系人"  
            android:textColor="#ffb7b7b7"  
            android:textSize="14.0sp"  
            android:visibility="gone" />  
    </FrameLayout>  
  
    <requestFocus />  
  
</LinearLayout>  

item的布局文件：

[html] view plaincopy
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    xmlns:tools="http://schemas.android.com/tools"  
    android:layout_width="match_parent"  
    android:layout_height="60dp" >  
  
    <LinearLayout  
        android:id="@+id/id_back"  
        android:layout_width="match_parent"  
        android:layout_height="match_parent"  
        android:background="#ffcccccc"  
        android:gravity="center|right" >  
  
        <Button  
            android:id="@+id/id_remove"  
            android:layout_width="60dp"  
            android:layout_height="wrap_content"  
            android:layout_gravity="center"  
            android:layout_marginRight="4dp"  
            android:background="@drawable/red_button"  
            android:text="Delete"  
            android:textColor="#fff" >  
        </Button>  
    </LinearLayout>  
  
    <LinearLayout  
        android:id="@+id/id_front"  
        android:layout_width="match_parent"  
        android:layout_height="match_parent"  
        android:background="#ffffffff" >  
  
        <TextView  
            android:id="@+id/id_text"  
            android:layout_width="wrap_content"  
            android:layout_height="wrap_content"  
            android:layout_marginLeft="10dp"  
            android:gravity="center_vertical"  
            android:minHeight="?android:attr/listPreferredItemHeight"  
            android:textAppearance="?android:attr/textAppearanceLarge"  
            android:textColor="#000"  
            android:textSize="25sp" >  
        </TextView>  
    </LinearLayout>  
  
</FrameLayout>  

注意对应布局的id和swipeListView中的frontView和backView的Id一致。

2、MainActivity

[java] view plaincopy
package com.example.zhy_swipelistview02;  
  
import java.util.ArrayList;  
import java.util.List;  
  
import android.app.Activity;  
import android.os.Bundle;  
import android.util.Log;  
import android.view.Window;  
  
import com.fortysevendeg.swipelistview.BaseSwipeListViewListener;  
import com.fortysevendeg.swipelistview.SwipeListView;  
  
public class MainActivity extends Activity  
{  
  
    protected static final String TAG = "Activity";  
    private SwipeListView mSwipeListView;  
    private DataAdapter mAdapter;  
    private List<String> mDatas;  
  
    @Override  
    protected void onCreate(Bundle savedInstanceState)  
    {  
        super.onCreate(savedInstanceState);  
        requestWindowFeature(Window.FEATURE_NO_TITLE);  
        setContentView(R.layout.activity_main);  
  
        initDatas();  
          
        mSwipeListView = (SwipeListView) findViewById(R.id.id_swipelistview);  
        mAdapter = new DataAdapter(this, mDatas , 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 initDatas()  
    {  
        mDatas = new ArrayList<String>();  
        for (int i = 'A'; i <= 'Z'; i++)  
            mDatas.add((char) i + "");  
    }  
  
}  

Adapter:

[java] view plaincopy
package com.example.zhy_swipelistview02;  
  
import java.util.List;  
  
import com.fortysevendeg.swipelistview.SwipeListView;  
  
import android.content.Context;  
import android.util.Log;  
import android.view.LayoutInflater;  
import android.view.View;  
import android.view.View.OnClickListener;  
import android.view.ViewGroup;  
import android.widget.BaseAdapter;  
import android.widget.Button;  
import android.widget.TextView;  
  
public class DataAdapter extends BaseAdapter  
{  
  
    private List<String> mDatas;  
    private LayoutInflater mInflater;  
    private SwipeListView mSwipeListView ;  
  
    public DataAdapter(Context context, List<String> datas , SwipeListView swipeListView)  
    {  
        this.mDatas = datas;  
        mInflater = LayoutInflater.from(context);  
        mSwipeListView = swipeListView;  
    }  
  
    @Override  
    public int getCount()  
    {  
        return mDatas.size();  
    }  
  
    @Override  
    public Object getItem(int position)  
    {  
        return mDatas.get(position);  
    }  
  
    @Override  
    public long getItemId(int position)  
    {  
        return position;  
    }  
  
    @Override  
    public View getView(final int position, View convertView, ViewGroup parent)  
    {  
        convertView = mInflater.inflate(R.layout.list_item, null);  
  
        TextView tv = (TextView) convertView.findViewById(R.id.id_text);  
        Button del = (Button) convertView.findViewById(R.id.id_remove);  
        tv.setText(mDatas.get(position));  
        del.setOnClickListener(new OnClickListener()  
        {  
            @Override  
            public void onClick(View v)  
            {  
                mDatas.remove(position);  
                notifyDataSetChanged();  
                 /** 
                  * 关闭SwipeListView 
                  * 不关闭的话，刚删除位置的item存在问题 
                  * 在监听事件中onListChange中关闭，会出现问题 
                  */  
                mSwipeListView.closeOpenedItems();  
            }  
        });  
          
        return convertView;  
    }  
  
}  

代码相当简单，MainActivity里面设置了监听事件，可以使用Demo的时候，观察触发的事件的输出，如果有特殊需求可以做一些操作。
