android视频播放器-源码

本文讲的是“android 视频播放器”，并附有播放器源代码1．开发环境：eclipse3.6ADT-0.9.7AVD1.62．程序运行效果A．启动AVD(虚拟设备)在应用程序界面主界面，我们可以看到“艾文播放器”B．点击打开后，会播放默认的一个coco的广告C．点击标题栏的按钮可以打开文件浏览器D．点击视频文件，会提示使用的播放器E．选择“艾文视频播放器”打开后，按ctrl+f12，切换到横屏，发现视频并没有中断，而是继续播放3．源码分析A．图片都是网上找的，还有就是自己收藏的地方翻出来的，不多讲了。

B．布局文件main.xml：期中包含一个videoview，用于播放视频图像titlebar.xml：主视图的标题栏布局，主要用于添加一个菜单按钮，点击后打开文件浏览器myfile.xml:为文件浏览器布局C．VideoPlay.javaview plaincopy to clipboardprint?1.package com.bestaone;2.3.import android.app.Activity;4.import android.content.Intent;5.import .Uri;6.import android.os.Bundle;7.import android.util.Log;8.import android.view.View;9.import android.view.View.OnClickListener;10.import android.view.Window;11.import android.view.WindowManager;12.import android.widget.ImageButton;13.import android.widget.MediaController;14.import android.widget.TextView;15.import android.widget.VideoView;16.17.public class VideoPlay extends Activity {18.19. private VideoView videoView;20. private static int index = 0;21.22.@Override23. public void onCreate(Bundle savedInstanceState) {24. super.onCreate(savedInstanceState);25. requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);26. setContentView(yout.main);27. getWindow().setFlags(youtParams.FLAG_FULLSCREEN, WindoyoutParams.FLAG_FULLSCREEN);//28. //设置标题栏的布局29. getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, yout.titlebar);30. //这个空间暂时没用31. final TextView titleTV = (TextView) findViewById(R.id.title);32. titleTV.setText("");33.
