Android使用SwipeListView实现类似QQ的滑动删除效果

前端技术 2023/09/06 Android

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:
