前言：项目中经常会用到类似于QQ侧滑点击删除的效果，网上的开源库也很多。个人感觉SwipeLayout最好用。下面介绍怎么使用。
一、首先导入需要的Jar包，有3个，AndroidSwipeLayout-v1.1.8.jar、AndroidViewAnimations-1.1.3.jar、nineoldandroids-2.4.0.jar。第一个jar包就是我们使用该控件的jar包，后面2个是侧滑出现删除menu的动画所需的jar包。下面就是怎么使用了。
主布局的xml文件如下，就是一个ListView：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/swipe_listview"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
</LinearLayout>
listview中的每个Item的布局如下：
<?xml version="1.0" encoding="utf-8"?>
<com.daimajia.swipe.SwipeLayout xmlns:swipe="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/swipe"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="80dp"
android:background="#FF5534"
android:gravity="center"
android:tag="Bottom3"
android:weightSum="10" >
<ImageView
android:id="@+id/trash"
android:layout_width="27dp"
android:layout_height="30dp"
android:layout_weight="1"
android:src="@drawable/trash" />
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5"
android:text="Delete Item?"
android:textColor="#fff"
android:textSize="17sp" />
<Button
android:id="@+id/delete"
android:layout_width="0dp"
android:layout_height="40dp"
android:layout_weight="4"
android:background="@drawable/white"
android:text="Yes,Delete"
android:textColor="#FF5534" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/item_selector"
android:padding="10dp" >
<TextView
android:id="@+id/position"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/text_data"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:tag="Hover"
android:text="Just Do it . " />
</LinearLayout>

上面的那个LinerLayout相当于bottomView,下面的那个相对应于SurfaceView。开始的时候SurfaceView显示在手机屏幕上，而bottomView则在屏幕外，随着手指的滑动渐渐显示在屏幕上。
Adapter.java如下：
package com.example.adapter;
import java.util.List;
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.TextView;
import android.widget.Toast;
import com.daimajia.androidanimations.library.Techniques;
import com.daimajia.androidanimations.library.YoYo;
import com.daimajia.swipe.SimpleSwipeListener;
import com.daimajia.swipe.SwipeLayout;
import com.daimajia.swipe.adapters.BaseSwipeAdapter;
import com.example.firstactivity.R;
public class ListViewAdapter extends BaseSwipeAdapter {
private Context mContext;
private List<String> mDatas;
//private TextView mDelete;
//private SwipeLayout swipeLayout;
private int pos ;
public ListViewAdapter(Context context, List<String> mDatas) {
this.mContext = context;
this.mDatas = mDatas;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return mDatas.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return mDatas.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public void fillValues(int position, View convertView) {
// TODO Auto-generated method stub
Log.e("fillValues", "position = "+position);
TextView tv = (TextView) convertView.findViewById(R.id.position);
//tv.setText((position + 1) + ".");
tv.setText(mDatas.get(position)+"....");
final SwipeLayout sl = (SwipeLayout) convertView.findViewById(getSwipeLayoutResourceId(position));
final TextView delete = (TextView) convertView.findViewById(R.id.delete);
delete.setTag(position);
delete.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
int pos = (Integer) delete.getTag();
String obj = mDatas.get(pos);
Log.e("onClick", "........pos ...."+pos+" obj = "+obj);
mDatas.remove(obj);
notifyDataSetChanged();
sl.close();
}
});
}
@Override
public View generateView(int position, ViewGroup arg1) {
// TODO Auto-generated method stub
Log.e("generateView", "position = "+position);
View v = LayoutInflater.from(mContext).inflate(R.layout.swipe_lv_item,null);
pos = position;
final SwipeLayout swipeLayout = (SwipeLayout) v.findViewById(R.id.swipe);
swipeLayout.addSwipeListener(new SimpleSwipeListener() {
@Override
public void onOpen(SwipeLayout layout) {//当隐藏的删除menu被打开的时候的回调函数
// TODO Auto-generated method stub
YoYo.with(Techniques.Tada).duration(500).delay(100).playOn(layout.findViewById(R.id.trash));
}
});
swipeLayout.setOnDoubleClickListener(new SwipeLayout.DoubleClickListener() {
@Override
public void onDoubleClick(SwipeLayout layout,
boolean surface) {
Toast.makeText(mContext, "DoubleClick",Toast.LENGTH_SHORT).show();
}
});
// v.findViewById(R.id.delete).setOnClickListener(
// new View.OnClickListener() {
// @Override
// public void onClick(View view) {
// Toast.makeText(mContext, "click delete position = "+pos,Toast.LENGTH_SHORT).show();
// swipeLayout.close();
// }
// });
return v;
}
@Override
public int getSwipeLayoutResourceId(int position) {
// TODO Auto-generated method stub
return R.id.swipe;
}
}
注意， generateView只是加布局，最好不要在里面设置点击事件。点击事件设置fillValues这个方法中。
Activity.java如下：
package com.example.firstactivity;
import java.util.ArrayList;
import java.util.List;
import com.example.adapter.ListViewAdapter;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;
import com.daimajia.swipe.util.Attributes;
public class SwipeListViewActivity extends Activity{
private ListView mListView;
private ListViewAdapter mAdapter;
private List<String> mDatas;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.swipe_layout_main);
getData();
mListView = (ListView) findViewById(R.id.swipe_listview);
mAdapter = new ListViewAdapter(this, mDatas);
mAdapter.setMode(Attributes.Mode.Single);
mListView.setAdapter(mAdapter);
}
public void getData(){
mDatas = new ArrayList<String>();
//for(int i =0; i<10; i++){
mDatas.add("A");
mDatas.add("B");
mDatas.add("C");
mDatas.add("D");
mDatas.add("E");
mDatas.add("F");
mDatas.add("G");
mDatas.add("H");
mDatas.add("I");
mDatas.add("J");
//}
}
}
