这是入口package com.example.soundpooldemo;import java.io.IOException;import android.app.Activity;import android.content.Intent;import android.media.AudioManager;import android.media.MediaPlayer;import android.media.SoundPool;import android.os.Bundle;import android.view.View;import android.view.View.MeasureSpec;import android.view.View.OnClickListener;import android.widget.Button;public class MainActivity extends Activity {	PRivate Button btn_playSoundpool;	private SoundPool sp;	private int sountID;	private Button btn_mediaplayer;	private MediaPlayer mp;	private Button btn_player;	private Button btn_videoView;	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);				btn_playSoundpool=(Button) findViewById(R.id.btn_playSoundpool);		btn_mediaplayer=(Button) findViewById(R.id.btn_mediaplayer);		btn_videoView=(Button) findViewById(R.id.btn_videoView);		btn_player=(Button) findViewById(R.id.btn_player);		sp=new SoundPool(1, AudioManager.STREAM_MUSIC, 0);		sountID=sp.load(this, R.raw.like, 1);		btn_playSoundpool.setOnClickListener(new OnClickListener() {						@Override			public void onClick(View v) {				// TODO Auto-generated method stub				//SoundPool只能播放短声音				sp.play(sountID, 1, 1, 0, 0, 1);			}		});		btn_mediaplayer.setOnClickListener(new OnClickListener() {						@Override			public void onClick(View v) {				// TODO Auto-generated method stub				if(mp!=null){					mp.start();				}							}		});		btn_player.setOnClickListener(new OnClickListener() {						@Override			public void onClick(View v) {				Intent video=new Intent();				video.setClass(MainActivity.this, PlayVideo.class);				startActivity(video);							}		});		btn_videoView.setOnClickListener(new OnClickListener() {						@Override			public void onClick(View v) {				Intent video=new Intent();				video.setClass(MainActivity.this, VideoViewPlay.class);				startActivity(video);							}		});	}	@Override	protected void onResume() {		// TODO Auto-generated method stub		mp=MediaPlayer.create(this, R.raw.like);		try {			mp.prepare();		} catch (IllegalStateException e) {			// TODO Auto-generated catch block			e.printStackTrace();		} catch (IOException e) {			// TODO Auto-generated catch block			e.printStackTrace();		}		super.onResume();	}	@Override	protected void onPause() {		// TODO Auto-generated method stub		if(mp!=null){			mp.release();		}		super.onPause();	}}<LinearLayout 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:orientation="vertical" >    <Button        android:id="@+id/btn_playSoundpool"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="SoundPool播放短声音" />    <Button	    android:id="@+id/btn_mediaplayer"	    android:layout_width="fill_parent"	    android:layout_height="wrap_content"	    android:text="MediaPlayer播放长长声音" />    <Button	    android:id="@+id/btn_player"	    android:layout_width="fill_parent"	    android:layout_height="wrap_content"	    android:text="MediaPlayer播放mp4视频" />     <Button	    android:id="@+id/btn_videoView"	    android:layout_width="fill_parent"	    android:layout_height="wrap_content"	    android:text="btn_videoView播放mp4视频" /></LinearLayout>这是PlayVideo播放视频的
package com.example.soundpooldemo;import java.io.IOException;import android.app.Activity;import android.media.MediaPlayer;import android.os.Bundle;import android.view.SurfaceHolder;import android.view.SurfaceHolder.Callback;import android.view.SurfaceView;public class PlayVideo extends Activity {	private SurfaceView sv;	private SurfaceHolder holder;	private Callback callBalk=new Callback() {		private MediaPlayer mp;				@Override		public void surfaceDestroyed(SurfaceHolder holder) {			// TODO Auto-generated method stub			mp.release();		}				@Override		public void surfaceCreated(SurfaceHolder holder) {			// TODO Auto-generated method stub			mp=MediaPlayer.create(PlayVideo.this, R.raw.ren);			try {					mp.prepare();			} catch (IllegalStateException e) {				// TODO Auto-generated catch block				e.printStackTrace();			} catch (IOException e) {				// TODO Auto-generated catch block				e.printStackTrace();			}			mp.setDisplay(holder);			mp.start();		}				@Override		public void surfaceChanged(SurfaceHolder holder, int format, int width,				int height) {			// TODO Auto-generated method stub					}	};	@Override	protected void onCreate(Bundle savedInstanceState) {		// TODO Auto-generated method stub		super.onCreate(savedInstanceState);		sv=new SurfaceView(this);		holder=sv.getHolder();		holder.addCallback(callBalk);		setContentView(sv);	}	}这是VideoView播放视频
