场景：像我们在Uber应用开场，看到一一段视频作为開始。这样子让用户非常快投入应用使用的场景中去，这样的以视频作为开场的应用，我们是不是认为非常高大上呢，哈哈，事实上是使用了SerfaceView去载入一段小视频，然后使用mediaplayer进行播放。然后循环。

先上图吧。

这里我贴出主要代码的实现

import java.io.IOException;

import android.app.Activity;

import android.content.Intent;

import android.content.res.AssetFileDescriptor;

import android.media.AudioManager;

import android.media.MediaPlayer;

import android.media.MediaPlayer.OnPreparedListener;

import android.os.Bundle;

import android.view.SurfaceHolder;

import android.view.SurfaceView;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener {

	private SurfaceView surfaceview;

	private Button btnGo;

	private MediaPlayer mediaPlayer;

	private int postion = 0;

	@Override

	protected void onCreate(Bundle savedInstanceState) {

		super.onCreate(savedInstanceState);

		setContentView(R.layout.activity_main);

		findViewById();

		initView();

	}

	protected void findViewById() {

		// TODO Auto-generated method stub

		surfaceview = (SurfaceView) findViewById(R.id.surfaceView);

		btnGo = (Button) findViewById(R.id.btn_goto);

	}

	protected void initView() {

		// TODO Auto-generated method stub

		mediaPlayer = new MediaPlayer();

		surfaceview.getHolder().setKeepScreenOn(true);

		surfaceview.getHolder().addCallback(new SurfaceViewLis());

		btnGo.setOnClickListener(this);

	}

	private class SurfaceViewLis implements SurfaceHolder.Callback {

		@Override

		public void surfaceChanged(SurfaceHolder holder, int format, int width,

				int height) {

		}

		@Override

		public void surfaceCreated(SurfaceHolder holder) {

			if (postion == 0) {

				try {

					play();

				} 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 holder) {

		}

	}

	public void play() throws IllegalArgumentException, SecurityException,

			IllegalStateException, IOException {

		mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

		AssetFileDescriptor fd = this.getAssets().openFd("start.mp4");

		mediaPlayer.setDataSource(fd.getFileDescriptor(), fd.getStartOffset(),

				fd.getLength());

		mediaPlayer.setLooping(true);

		mediaPlayer.setDisplay(surfaceview.getHolder());

		// 通过异步的方式装载媒体资源

		mediaPlayer.prepareAsync();

		mediaPlayer.setOnPreparedListener(new OnPreparedListener() {

			@Override

			public void onPrepared(MediaPlayer mp) {

				// 装载完成回调

				mediaPlayer.start();

			}

		});

	}

	@Override

	public void onClick(View v) {

		switch (v.getId()) {

		case R.id.btn_goto:

			startActivity(new Intent(this, OtherActivity.class));

			finish();

			break;

		default:

			break;

		}

	}

}
