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
<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:
<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
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;@Overrideprotected 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(){@Overridepublic void onChoiceChanged(int position, boolean selected){Log.d(TAG, "onChoiceChanged:" + position + ", " + selected);}@Overridepublic void onChoiceEnded(){Log.d(TAG, "onChoiceEnded");}@Overridepublic void onChoiceStarted(){Log.d(TAG, "onChoiceStarted");}@Overridepublic void onClickBackView(int position){Log.d(TAG, "onClickBackView:" + position);}@Overridepublic void onClickFrontView(int position){Log.d(TAG, "onClickFrontView:" + position);}@Overridepublic void onClosed(int position, boolean fromRight){Log.d(TAG, "onClosed:" + position + "," + fromRight);}@Overridepublic void onDismiss(int[] reverseSortedPositions){Log.d(TAG, "onDismiss");}@Overridepublic void onFirstListItem(){Log.d(TAG, "onFirstListItem");}@Overridepublic void onLastListItem(){Log.d(TAG, "onLastListItem");}@Overridepublic void onListChanged(){Log.d(TAG, "onListChanged");mSwipeListView.closeOpenedItems();}@Overridepublic void onMove(int position, float x){Log.d(TAG, "onMove:" + position + "," + x);}@Overridepublic void onOpened(int position, boolean toRight){Log.d(TAG, "onOpened:" + position + "," + toRight);}@Overridepublic void onStartClose(int position, boolean right){Log.d(TAG, "onStartClose:" + position + "," + right);}@Overridepublic 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:
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;}@Overridepublic int getCount(){return mDatas.size();}@Overridepublic Object getItem(int position){return mDatas.get(position);}@Overridepublic long getItemId(int position){return position;}@Overridepublic 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(){@Overridepublic 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。
