最近几天被多媒体搞的头都大了，可能最近几天更新的都是和多媒体有关的，之前出现播放器放不出来歌，居然是环境的问题，想想也是伤感，

MediaPlayer，属于播放音乐的一种，还有一种是SoundPool,下一篇文章会介绍。

一般来说，MediaPlayer可以说有两种播放音乐的方式，一种是通过setDataSource,然后就是同步或者异步prepare,还有一种就是通过create，据说create里面自己包含了prepare，所以我也不知道他们有什么区别，反正知道使用的方式就是了嘛，贴代码，如此简洁的代码都不能看懂的话，我也就没有什么办法了。

package com.example.musicdemo;import java.io.File;import java.io.IOException;import android.media.MediaPlayer;import android.net.Uri;import android.os.Bundle;import android.app.Activity;import android.view.Menu;import android.view.View;import android.widget.Button;import android.widget.Toast;public class MainActivity extends Activity {MediaPlayer myMediaPlayer;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);// playMusic3();// playMusic1();playMusic2();// actually ,there is a way that can use URL to play music,but i can't// find a right url ,you can try}private void playMusic3() {// actually this is the same with the first,just the parm is not the// samemyMediaPlayer = MediaPlayer.create(this,Uri.fromFile(new File("/sdcard/ty.mp3")));myMediaPlayer.start();}private void playMusic2() {myMediaPlayer = new MediaPlayer();try {// Initialized the MediaPlayermyMediaPlayer.reset();// set the datasource pathmyMediaPlayer.setDataSource("/sdcard/ty.mp3");// synchronized load the music// myMediaPlayer.prepare();// Asynchronized load the music is much difficult,i will updata it// later// myMediaPlayer.prepareAsync();System.out.println("3333333333");myMediaPlayer.start();System.out.println("4444444444");} catch (IllegalArgumentException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (SecurityException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IllegalStateException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}private void playMusic1() {// play the music by read the resource// rember the create is the method that belong to MediaPlayer,if you use// the MediaPlayer's object's way ,it will wrongmyMediaPlayer = MediaPlayer.create(this, R.raw.ty);// if you use the way that called create to initialized the music,there// is no need for the method prepare,because create contains preparemyMediaPlayer.start();}}
