[操作系统]SwipeListView的使用


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 ="http://schemas.android.com/apk/res/android"  ="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      ="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: 

<??><FrameLayout ="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:
