写下关于popwindow

主要是代码，参考了http://blog.csdn.net/Android_Tutor/archive/2010/05/10/5576533.aspx

popwindow.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"><TextViewandroid:id="@+id/textview"android:layout_width="fill_parent"android:layout_height="wrap_content"android:text="测试"/><Buttonandroid:id="@+id/test"android:layout_width="fill_parent"android:layout_height="wrap_content"android:text="测试"/></LinearLayout>

main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/main" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" ><VideoViewandroid:id="@+id/videoshow"android:layout_width="fill_parent"android:layout_height="fill_parent"/></LinearLayout>

Activity01.java

package com.overflow.testvideo;import java.util.Timer;import java.util.TimerTask;import android.app.Activity;import android.content.Context;import android.net.Uri;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.view.Gravity;import android.view.KeyEvent;import android.view.LayoutInflater;import android.view.MotionEvent;import android.view.View;import android.view.ViewGroup.LayoutParams;import android.widget.Button;import android.widget.MediaController;import android.widget.PopupWindow;import android.widget.TextView;import android.widget.VideoView;public class Activity01 extends Activity {VideoView vv = null;Button btn = null;TextView textview = null; /** Called when the activity is first created. */private Handler mHandler = new Handler(){public void handleMessage(Message msg) {switch (msg.what) {case 1:showPopupWindow();break;}};}; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Timer timer = new Timer(); timer.schedule(new initPopupWindow(), 100); //textview = (TextView) music_popunwindwow. //btn = (Button) this.findViewById(R.id.test); vv = (VideoView) this.findViewById(R.id.videoshow); vv.setVideoURI(Uri.parse("android.resource://com.overflow.testvideo/"+R.raw.underwater)); vv.setMediaController(new MediaController(this)); vv.start(); vv.setOnTouchListener(new VideoView.OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {// TODO Auto-generated method stubreturn true;} }); } private class initPopupWindow extends TimerTask{@Overridepublic void run() {Message message = new Message();message.what = 1;mHandler.sendMessage(message);} } public void showPopupWindow() {Context mContext = Activity01.this;LayoutInflater mLayoutInflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);View music_popunwindwow = mLayoutInflater.inflate(R.layout.popwindow, null);PopupWindow mPopupWindow = new PopupWindow(music_popunwindwow,LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);mPopupWindow.showAtLocation(findViewById(R.id.main), Gravity.CENTER, 0, 0);btn = (Button) music_popunwindwow.findViewById(R.id.test);textview = (TextView) music_popunwindwow.findViewById(R.id.textview);btn.setOnClickListener(new Button.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubtextview.setText("测试成功");} });}}

记得要dismiss(),否则返回会报错，难点在要触发popwindow上的事件，就必须是这个popwindow下来findviewbyid,否则就报错

本来这个东西的最初目的是写动态背景，但失败了，蛮多限制。贴上代码，以后可能需要。

还一些参考文章：http://www.cmd100.com/bbs/thread-111-1-1.html
