android开发中popwindow的使用，首先需要定义popwindow的布局，这里定义的比较简单

pop_item.xml

<?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"
    android:background="#ff0000" >

    <Button
        android:id="@+id/ok"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="确定" />

    <Button
        android:id="@+id/cancle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="取消" />
	
</LinearLayout>

在MainActivity中获得自定义的popWindow布局，实例化popwindow对象，然后定义其显示位置，显示动画等

MainActivity.java

package com.example.popwindow;

import android.os.Bundle;
import android.app.Activity;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.PopupWindow;
import android.widget.Toast;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		Button open = (Button) findViewById(R.id.open);
		open.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_item,null);
				Button ok = (Button) view.findViewById(R.id.ok);
				Button cancle = (Button) view.findViewById(R.id.cancle);
				
				final PopupWindow popWindow = new PopupWindow(view, 100,100);
				popWindow.setAnimationStyle(R.anim.pop);
				popWindow.showAsDropDown(arg0);
				ok.setOnClickListener(new OnClickListener() {
					
					@Override
					public void onClick(View arg0) {
						// TODO Auto-generated method stub
						Toast.makeText(MainActivity.this,"you click ok",1000).show();
					}
				});
				cancle.setOnClickListener(new OnClickListener() {
					
					@Override
					public void onClick(View arg0) {
						// TODO Auto-generated method stub
						popWindow.dismiss();
					}
				});
			}
		});
		
	}

}

pop.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <alpha android:fromAlpha="0"
           android:toAlpha="1"
           android:duration="2000">
    </alpha>
</set>
