本文详细介绍了在Android应用中播放视频文件的三种方法：使用系统自带的播放器、SurfaceView和VideoView组件。分别提供了对应的代码实现，包括系统播放器的Intent启动方式、SurfaceView的MediaPlayer集成使用、以及VideoView的简单配置与事件监听。

有三种方法播放视频文件。

1.使用系统自带的播放器

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		Uri uri = Uri.parse(Environment.getExternalStorageDirectory()
				.getPath()+"/test.mp4");
		Intent intent = new Intent(Intent.ACTION_VIEW);
		intent.setDataAndType(uri, "video/mp4");
		startActivity(intent);
	}


}

2.使用surfaceView

public class MainActivity extends Activity implements SurfaceHolder.Callback,
		OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener {

	SurfaceView surfaceView;
	SurfaceHolder holder;
	String path;
	MediaPlayer mediaPlayer;
	int videoWidth;
	int videoHeight;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		
		surfaceView = (SurfaceView) findViewById(R.id.surface);
		holder = surfaceView.getHolder();
		holder.addCallback(this);
		holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		return super.onOptionsItemSelected(item);
	}

	@Override
	public void onPrepared(MediaPlayer arg0) {
		videoWidth = mediaPlayer.getVideoWidth();
		videoHeight = mediaPlayer.getVideoHeight();
		if (videoWidth != 0 && videoHeight != 0) {
			holder.setFixedSize(videoWidth, videoHeight);// 设置视频的宽度和高度
			mediaPlayer.start();

		}
	}

	@Override
	public void onCompletion(MediaPlayer arg0) {
		// TODO Auto-generated method stub

	}

	@Override
	public void onBufferingUpdate(MediaPlayer arg0, int arg1) {
		// TODO Auto-generated method stub

	}

	@Override
	public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) {
		// TODO Auto-generated method stub

	}

	@Override
	public void surfaceCreated(SurfaceHolder arg0) {
		path = Environment.getExternalStorageDirectory().getPath()+"/test.mp4";
		mediaPlayer = new MediaPlayer();

		try {
			mediaPlayer.setDataSource(path);
			mediaPlayer.setDisplay(holder);// 设置通过surfaceView来显示画面
			mediaPlayer.prepare();
			mediaPlayer.setOnBufferingUpdateListener(this);
			mediaPlayer.setOnCompletionListener(this);
			mediaPlayer.setOnPreparedListener(this);
			mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (SecurityException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalStateException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

	@Override
	public void surfaceDestroyed(SurfaceHolder arg0) {
		// TODO Auto-generated method stub

	}

	@Override
	protected void onDestroy() {
		// TODO Auto-generated method stub
		super.onDestroy();
		if (mediaPlayer != null) {
			mediaPlayer.release();
			mediaPlayer = null;

		}
	}
}

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.videoplayerwithsurfaceview.MainActivity" >

	<SurfaceView 
	    android:id="@+id/surface"
	    android:layout_width="match_parent"
	    android:layout_height="match_parent"/>
</RelativeLayout>

3.使用VideoView

public class MainActivity extends Activity {

	VideoView videoView;
	Button play,pause,load;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		videoView = (VideoView) findViewById(R.id.video);
		play = (Button) findViewById(R.id.btn_play);
		pause = (Button) findViewById(R.id.btn_pause);
		load = (Button) findViewById(R.id.btn_load);
		
		
		
		load.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				
				videoView.setVideoPath(Environment.getExternalStorageDirectory().getPath()+"/test.mp4");
				videoView.setMediaController(new MediaController(MainActivity.this));
				videoView.requestFocus();
				
			}
		});
		
		play.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {

				videoView.start();
			}
		});
		
		
		pause.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {

				videoView.pause();
			}
		});
		
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		
		return true;
	}

}

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <VideoView
        android:id="@+id/video"
        android:layout_width="fill_parent"
        android:layout_height="200dp" />

    <Button
        android:id="@+id/btn_load"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/video"
        android:layout_marginLeft="50dp"
        android:text="装载" />

    <Button
        android:id="@+id/btn_pause"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/video"
        android:layout_toRightOf="@id/btn_load"
        android:text="暂停" />

    <Button
        android:id="@+id/btn_play"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/video"
        android:layout_toRightOf="@id/btn_pause"
        android:text="播放" />

</RelativeLayout>
