在Android中，实现视频的播放有多中方式，其中用到比较多的是使用Video View 或者是surface View来实现

1、使用Video View 实现

1.1 对应的布局文件

<FrameLayout 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"    tools:context=".VideoViewActivity" >    <VideoView        android:id="@+id/videoView"        android:layout_width="match_parent"        android:layout_height="match_parent" />    <ProgressBar        android:id="@+id/progressBar1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:visibility="gone" /></FrameLayout>

1.2 对应的code的实现

package com.android.bootvideo;import android.app.Activity;import android.media.MediaPlayer;import android.net.Uri;import android.os.Bundle;import android.os.Handler;import android.os.SystemProperties;import android.view.KeyEvent;import android.widget.VideoView;public class VideoViewActivity extends Activity implements MediaPlayer.OnErrorListener,        MediaPlayer.OnCompletionListener {    private static final String TAG = "VideoViewActivity";    private Uri mUri;    private VideoView mVideoView;    private final int BOOT_VIDEO_LIMIT = 20 * 1000;    Handler mHandler = new Handler();    private Runnable mPlayVideoRunnable = new Runnable() {        @Override        public void run() {            XLog.d(TAG, "mPlayVideoRunnable, run()");            mHandler.removeCallbacks(mPlayVideoRunnable);            XLog.v(TAG, "playVideo Current Source is storage");            playVideoSetUp();        }    };    private Runnable mStopPlayVideoRunnable = new Runnable() {        @Override        public void run() {            XLog.d(TAG, "wait 20s for bootvideo time out!");            finish();        }    };    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        XLog.d(TAG, "onCreate()");        setContentView(R.layout.activity_video_view);        mVideoView = (VideoView) findViewById(R.id.videoView);        playVideoSetUp();    }    private void playVideoSetUp() {        XLog.i(TAG, "playVideoSetUp()");        String path = SystemProperties.get(Util.BOOT_VIDEO_PATH);        XLog.i(TAG, "video path: " + path);        if (Util.bootVideoNotExist()) {            XLog.i(TAG, path + " file not exist");            return;        }        mUri = Uri.parse(path);        mVideoView.setVideoURI(mUri);        mVideoView.start();        mVideoView.setOnErrorListener(this);        mVideoView.setOnCompletionListener(this);        mHandler.postDelayed(mStopPlayVideoRunnable, BOOT_VIDEO_LIMIT);    }    private void playVideoStop() {        XLog.i(TAG, "stopSetup()");        mHandler.removeCallbacks(mPlayVideoRunnable);        mHandler.removeCallbacks(mStopPlayVideoRunnable);        mVideoView.stopPlayback();    }    @Override    public void onBackPressed() {        XLog.i(TAG, "onBackPressed()");        return;    }    @Override    public boolean dispatchKeyEvent(KeyEvent event) {        int keyCode = event.getKeyCode();        XLog.i(TAG, "dispatchKeyEvent() keyCode = " + keyCode);        switch (keyCode) {        case KeyEvent.KEYCODE_BACK:        case KeyEvent.KEYCODE_VOLUME_UP:        case KeyEvent.KEYCODE_VOLUME_DOWN:        case KeyEvent.KEYCODE_VOLUME_MUTE: {            return super.dispatchKeyEvent(event);        }        default:            break;        }        return true;    }    @Override    protected void onResume() {        super.onResume();        XLog.d(TAG, "onResume");    }    @Override    protected void onPause() {        XLog.d(TAG, "onPause ");        super.onPause();    }    @Override    protected void onStart() {        super.onStop();        XLog.d(TAG, "onStart");    }    @Override    protected void onStop() {        super.onStop();        XLog.d(TAG, "onStop");    }    @Override    protected void onDestroy() {        super.onDestroy();        playVideoStop();        XLog.d(TAG, "onDestroy");    }    @Override    public boolean onError(MediaPlayer mediaplay, int what, int extra) {        XLog.d(TAG, "onError() framework_err " + what + " impl_err:" + extra);        finish();        if (extra == MediaPlayer.MEDIA_ERROR_TIMED_OUT) {            return true;        }        return false;    }    @Override    public void onCompletion(MediaPlayer mediaplay) {        XLog.i(TAG, "onCompletion()");        finish();    }}

2、使用surface View 实现

2.1 对应的布局文件

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    tools:context="com.android.bootvideo.SurfaceViewActivity" >    <SurfaceView        android:id="@+id/surfaceView"        android:layout_width="fill_parent"        android:layout_height="fill_parent" /></FrameLayout>

2.2 对应的实现

package com.android.bootvideo;import android.app.Activity;import android.media.MediaPlayer;import android.os.Bundle;import android.os.Handler;import android.os.SystemProperties;import android.view.KeyEvent;import android.view.SurfaceHolder;import android.view.SurfaceView;public class SurfaceViewActivity extends Activity implements        MediaPlayer.OnPreparedListener,        MediaPlayer.OnCompletionListener,        MediaPlayer.OnErrorListener {    private final String TAG = "MainActivity";    private SurfaceView mSurfaceView = null;    private SurfaceHolder mSurfaceHolder = null;    private MediaPlayer mMediaPlayer = null;    private final int BOOT_VIDEO_LIMIT = 20 * 1000;    Handler mHandler = new Handler();    private Runnable mStopPlayVideoRunnable = new Runnable() {        @Override        public void run() {            XLog.d(TAG, "wait 20s for bootvideo time out!");            finish();        }    };    @Override    protected void onCreate(Bundle savedInstanceState) {        XLog.i(TAG, "onCreate()");        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_surface_view);        mSurfaceView = (SurfaceView) findViewById(R.id.surfaceView);        mSurfaceHolder = mSurfaceView.getHolder();        mSurfaceHolder.addCallback(new SurfaceHolderCallback());        playVideoSetUp();    }    @Override    protected void onResume() {        super.onResume();        XLog.i(TAG, "onResume()");    }    @Override    protected void onPause() {        super.onPause();        XLog.i(TAG, "onPause() ");    }    @Override    protected void onDestroy() {        super.onDestroy();        playVideoStop();        XLog.i(TAG, "onDestroy()");    }    @Override    public boolean dispatchKeyEvent(KeyEvent event) {        int keyCode = event.getKeyCode();        XLog.i(TAG, "dispatchKeyEvent() keyCode = " + keyCode);        switch (keyCode) {        case KeyEvent.KEYCODE_VOLUME_UP:        case KeyEvent.KEYCODE_VOLUME_DOWN:        case KeyEvent.KEYCODE_VOLUME_MUTE: {            return super.dispatchKeyEvent(event);        }        default:            break;        }        return true;    }    @Override    public void onBackPressed() {        XLog.i(TAG, "onBackPressed()");        return;    }    private void playVideoSetUp() {        XLog.i(TAG, "playVideoSetUp()");        String path = SystemProperties.get(Util.BOOT_VIDEO_PATH);        XLog.i(TAG, "video path: " + path);        if (Util.bootVideoNotExist()) {            XLog.i(TAG, path + " file not exist");            return;        }        try {            mMediaPlayer = new MediaPlayer();            mMediaPlayer.setDataSource(path);            mMediaPlayer.setOnPreparedListener(this);            mMediaPlayer.setOnCompletionListener(this);            mMediaPlayer.setOnErrorListener(this);            mMediaPlayer.prepare();            mMediaPlayer.seekTo(0);            mMediaPlayer.start();        } catch (Exception e) {            XLog.i(TAG, "exceptipn error!");            finish();        } finally {            mHandler.postDelayed(mStopPlayVideoRunnable, BOOT_VIDEO_LIMIT);        }    }    private void playVideoStop() {        XLog.i(TAG, "stopSetup()");        mHandler.removeCallbacks(mStopPlayVideoRunnable);        mMediaPlayer.stop();    }    private class SurfaceHolderCallback implements SurfaceHolder.Callback {        @Override        public void surfaceCreated(SurfaceHolder holder) {            XLog.i(TAG, "surfaceCreated()");            mMediaPlayer.setDisplay(holder);        }        @Override        public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {            XLog.i(TAG, "surfaceChanged()");        }        @Override        public void surfaceDestroyed(SurfaceHolder holder) {            XLog.i(TAG, "surfaceDestroyed()");        }    }    @Override    public void onPrepared(MediaPlayer player) {        XLog.i(TAG, "onPrepared()");        int width = player.getVideoWidth();        int height = player.getVideoHeight();        XLog.i(TAG, "with = " + width + ",height = " + height);        // mSurfaceView.setLayoutParams(new LinearLayout.LayoutParams(width, height));    }    @Override    public void onCompletion(MediaPlayer player) {        XLog.i(TAG, "onCompletion()");        finish();    }    @Override    public boolean onError(MediaPlayer player, int whatError, int extra) {        XLog.i(TAG, "onError() whatError = " + whatError);        finish();        return false;    }}
