SwipeListView：listview的侧滑功能

listview的侧滑功能，需要集成第三方的自定义控件SwipeListView。先看一下效果图

下面详细记录一下集成步骤

          首先将四个java文件复制到自己的项目中分别是BaseSwipeListViewListener，SwipeListView，SwipeListViewListener，SwipeListViewTouchListener。然后需要导入一个jar包到libs文件中，jar包名为nineoldandroids-2.4.0.jar

          集成好SwipeListview控件的环境后，下面看下具体如何用

listView中的item如何写？

          items用的是FrameLayout写，保证滑动的时候有上下两层图片，可以看到第一层布局是linealayout，id为back，添加了tag=back，这个布局滑动后显示的，第二层布局也是linearlayout，添加了id为front，这个布局是显示在前面的

<?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="wrap_content"    android:background="@drawable/edit_frame" >    <LinearLayout        android:orientation="horizontal"        android:id="@+id/back"        android:layout_width="match_parent"        android:layout_height="fill_parent"         android:background="#31d0cc"        android:baselineAligned="false"                android:tag="back" >        <TextView            android:layout_width="0dip"            android:layout_height="fill_parent"            android:layout_weight="3"                      >        </TextView>        <LinearLayout            android:id="@+id/del"            android:layout_width="0dip"            android:layout_height="wrap_content"            android:layout_gravity="center_vertical"            android:layout_weight="1"            android:orientation="vertical" >            <ImageView                android:layout_width="35dp"                android:layout_height="35dp"                android:layout_gravity="center"                android:contentDescription="@string/image_tag"                android:src="@drawable/del"                android:textSize="12sp" />            <TextView                android:layout_width="wrap_content"                android:layout_height="20dip"                android:layout_gravity="center"                android:gravity="center"                android:text="@string/delete"                android:textAppearance="?android:attr/textAppearanceLarge"                android:textColor="#FFFFFF"                android:textSize="12sp" />        </LinearLayout>    </LinearLayout>    <LinearLayout        android:id="@+id/front"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="#FFFFFF"        android:orientation="vertical" >        <TextView            android:id="@+id/name"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="15dp"            android:layout_marginTop="3dp"            android:text="张强"            android:textColor="#000000"            android:textSize="18sp" />        <RelativeLayout            android:layout_width="fill_parent"            android:layout_height="wrap_content" >            <TextView                android:id="@+id/position"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_marginLeft="15dp"                android:text="@string/position"                android:textColor="#000000" />            <TextView                android:id="@+id/position_txt"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_marginLeft="5dp"                android:layout_toRightOf="@+id/position"                android:text="上海总管"                android:textColor="#000000" />        </RelativeLayout>        <RelativeLayout            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:layout_marginBottom="3dp" >            <TextView                android:id="@+id/tel"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_marginLeft="15dp"                android:text="@string/phone_num"                android:textColor="#000000" />            <TextView                android:id="@+id/tel_txt"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_marginLeft="5dp"                android:layout_toRightOf="@+id/tel"                android:text="15934758086"                android:textColor="#000000" />        </RelativeLayout>    </LinearLayout></FrameLayout>

items布局写完后看下listview的写法,其中很多属性是设置swipelistview的，swipeOpenOnLongPress="false"意思是不能长按，app:swipeMode="left"的意思是可以向左滑动

app:swipeBackView="@+id/back"这里就是讲listview的背后控件应用过来了，swipeFrontView="@+id/front"把滑动的前面的布局引用过来，back和front都是上面xml中的控件。

app:swipeOffsetLeft="0dp"表示的是滑动之后上一层布局在左侧有多宽的位置，也就是我图中的白色的宽度。这个也可以在代码中设置

<com.myapp.widget.SwipeListView     android:layout_height="fill_parent"    android:layout_width="fill_parent"    android:id="@+id/listview"    android:dividerHeight="5dp"    android:scrollbars="none"    android:divider="@null"    android:layout_marginLeft="8dp"    android:layout_marginRight="8dp"    android:layout_marginTop="8dp"    android:layout_marginBottom="3dp"    app:swipeActionLeft="reveal"    app:swipeActionRight="reveal"    app:swipeAnimationTime="0"                app:swipeBackView="@+id/back"                    app:swipeCloseAllItemsWhenMoveList="true"                    app:swipeFrontView="@+id/front"                    app:swipeMode="left"                    app:swipeOffsetLeft="0dp"                    app:swipeOffsetRight="0dp"                    app:swipeOpenOnLongPress="false"     />

listview和items都写好之后就要写，看下adapter怎么写,adapter的构造器中传入了一个mSwipeListView，然后delete的监听事件里调用了mSwipeListView.closeAnimate(position); mSwipeListView.dismiss(position);这两个方法，可以将点击的这个item隐藏了。记住这个方法。

package com.myapp.adapter;import java.util.ArrayList;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.view.View.OnClickListener;import android.widget.BaseAdapter;import android.widget.LinearLayout;import android.widget.TextView;public class CustomerLeadersAdapter extends BaseAdapter {private ArrayList<String> data;private Context context;private LayoutInflater inflater;private SwipeListView mSwipeListView;public CustomerLeadersAdapter(ArrayList<String> data, Context context,SwipeListView mSwipeListView){this.data = data;this.context = context;inflater = LayoutInflater.from(context);this.mSwipeListView = mSwipeListView;}@Overridepublic int getCount() {// TODO Auto-generated method stubreturn data.size();}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic View getView(final int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubViewHolder holder = null;if(convertView == null){holder = new ViewHolder();convertView = inflater.inflate(R.layout.customer_leaders_item, null);holder.name = (TextView) convertView.findViewById(R.id.name);holder.phoneNum = (TextView) convertView.findViewById(R.id.tel_txt);holder.positionTxt = (TextView) convertView.findViewById(R.id.position_txt);holder.delete = (LinearLayout) convertView.findViewById(R.id.del);convertView.setTag(holder);}else{holder = (ViewHolder) convertView.getTag();}holder.name.setText(data.get(position));holder.delete.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {mSwipeListView.closeAnimate(position);mSwipeListView.dismiss(position);}});return convertView;}public static class ViewHolder{private TextView name,phoneNum,positionTxt;public LinearLayout delete;}}

最后在activity中显示自己的listview，注意BaseSwipeListViewListener，在这个监听事件中，只要监听到dismiss方法调用的时候就会调用onDismiss()方法，我们在onDismiss方法中可以进行数据的删除操作。BaseSwipeListViewListener中还有很多监听事件可以供我们选择，不仅是删除功能，还可以做成菜单的功能等等。

package com.myapp.app;import java.util.ArrayList;import android.app.Fragment;import android.os.Bundle;import android.util.Log;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.view.ViewTreeObserver;import android.view.ViewTreeObserver.OnGlobalLayoutListener;public class ContactFragment extends Fragment{private SwipeListView listview;private ArrayList<String> data;private CustomerLeadersAdapter adapter;public static int deviceWidth;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {// TODO Auto-generated method stubView view = inflater.inflate(R.layout.contact_layout, container, false);data = new ArrayList<String>();data.add("张三");data.add("李四");data.add("王五");data.add("刘麻子");data.add("增强");data.add("罗坑");listview = (SwipeListView) view.findViewById(R.id.listview);adapter = new CustomerLeadersAdapter(data, getActivity().getApplicationContext(), listview);listview.setAdapter(adapter);listview.setSwipeListViewListener(new ContactBaseSwipeListViewListener());deviceWidth = getDeviceWidth();Log.i("Tag", "====width==="+deviceWidth);reload();return view;}private void reload() {listview.setSwipeMode(SwipeListView.SWIPE_MODE_LEFT);listview.setSwipeActionLeft(SwipeListView.SWIPE_ACTION_REVEAL);// listview.setSwipeActionRight(settings.getSwipeActionRight());listview.setOffsetLeft(deviceWidth * 67 / 100);// listview.setOffsetRight(convertDpToPixel(settings.getSwipeOffsetRight()));listview.setAnimationTime(0);listview.setSwipeOpenOnLongPress(false);}//预留用来计算listview宽度的四分之三//private int getDeviceWidth() {//ViewTreeObserver vto2 = listview.getViewTreeObserver(); //vto2.addOnGlobalLayoutListener(new OnGlobalLayoutListener() { //@Override//public void onGlobalLayout() { //listview.getViewTreeObserver().removeGlobalOnLayoutListener(this); //deviceWidth = listview.getWidth();//} //});//return deviceWidth;//}private int getDeviceWidth() {return getResources().getDisplayMetrics().widthPixels;}/** * 当调用dismiss()方法的时候会调用onDismiss方法，所以在adapter中用mSwipeListView.dismiss(position)的时候 * 就会调用这个方法进行数据的删除操作 * @author Administrator * */class ContactBaseSwipeListViewListener extends BaseSwipeListViewListener {@Overridepublic void onClickFrontView(int position) {super.onClickFrontView(position);}@Overridepublic void onDismiss(int[] reverseSortedPositions) {for (int position : reverseSortedPositions) {//这里进行删除数据的操作}adapter.notifyDataSetChanged();}}}

到此全部结束。
