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。
