2011.08.12——— android MediaPlayer

写一个简单的播放mp3的程序，一直报错

DEBUG/MediaPlayer(3662): java.io.IOException: Prepare failed.: status=0x1

很是郁闷

后来感觉是

mMediaPlayer.prepare();

必须单独try catch起来当我爸try catch去掉时一样报上面的错误

不是很明白

package com.lp;import java.io.IOException;import android.app.Activity;import android.media.MediaPlayer;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;public class MainActivity extends Activity {private Button play;private Button stop;private boolean isReleased= false;private boolean isPlaying= false;private MediaPlayer mMediaPlayer = new MediaPlayer();    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        play = (Button)findViewById(R.id.main_play);        stop = (Button)findViewById(R.id.main_stop);        play.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {try{if ( !isPlaying ){/* 装载资源中的音乐 */mMediaPlayer = MediaPlayer.create(MainActivity.this, R.raw.aa);isPlaying = true;isReleased = false;/* 设置是否循环 */mMediaPlayer.setLooping(true);try{mMediaPlayer.prepare();}catch (IllegalStateException e){e.printStackTrace();}catch (IOException e){e.printStackTrace();}mMediaPlayer.start();}}catch (IllegalStateException e){e.printStackTrace();}}        });                stop.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {if(isPlaying&&!isReleased){isReleased = true;mMediaPlayer.stop();mMediaPlayer.release();isPlaying = false;}}});    }}
