Android多媒体开发【2】-- 利用VideoView开发最简单的视频播放器

接下来贴出main.xml的源码:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent" >   <VideoView        android:id="@+id/videoView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content" /></RelativeLayout>

接下来贴出程序源码：

package com.example.mpy;import android.net.Uri;import android.os.Bundle;import android.os.Environment;import android.app.Activity;import android.view.Menu;import android.widget.VideoView;public class MainActivity extends Activity {VideoView videoView ;      @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        videoView = (VideoView)this.findViewById(R.id.videoView1);                Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()+"/Movies/run_to_you.3gp");                      //Log.d(ALARM_SERVICE, Environment.getExternalStorageDirectory().getPath());          videoView.setVideoURI(uri);           videoView.start();    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.activity_main, menu);        return true;    }}

运行结果截图：
