Android使用SwipeListView實現類似QQ的滑動刪除效果

QQ的滑動刪除效果很不錯，要實現這種效果，可以使用SwipeListView。

1. 下載com.fortysevendeg.swipelistview這個項目（以前GitHub上有，現在GitHub上沒有了，百度了很多次才下載到的）,導入Eclipse，右鍵單擊，選擇Properties->Android，選中Library下面的IsLibrary。

2. 新建一個項目MySwipeListView，加入SwipeListView這個庫。

3. 在主窗體裡面放入一個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>

其中兩個重要的屬性：
swipe:swipeFrontView：上面的View，即不滑動時顯示的View。
swipe:swipeBackView：下面的View，即滑動後顯示的View。
這兩個View都定義在SwipeListView的行布局文件裡面： 

<?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="刪除"/>

    <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裡面所有的所有子元素都堆疊在FrameLayout的左上角。 

4. SwipeListView和其他ListView一樣，也需要Adapter，使用方法也是一樣的。這裡就不詳細講了。 

5. 在主窗體Java文件中實現SwipeListView的功能，代碼如下：

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("這是第" + i +"條數據!"); 
  }
  
}

最主要的代碼即mSwipeListView.setSwipeListViewListener(new BaseSwipeListViewListener(){})，通過這行代碼，為SwipeListView控件設置了Listener，可以根據自己的需要重載BaseSwipeListViewListener的各種方法。
