本文实例为大家分享了Android音乐播放器的具体代码，供大家参考，具体内容如下

1.播放项目内的音乐

package com.thm.g150820_android26_playmusic;

import Android.media.MediaPlayer;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.ImageButton;

import android.widget.SeekBar;

public class MainActivity extends AppCompatActivity {

private MediaPlayer mediaPlayer;

private SeekBar seekBar;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

seekBar = (SeekBar) findViewById(R.id.seekBar);

seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

@Override

public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

}

@Override

public void onStartTrackingTouch(SeekBar seekBar) {

}

@Override

public void onStopTrackingTouch(SeekBar seekBar) {

//获取拖动结束之后的位置

int progress = seekBar.getProgress();

//跳转到某个位置播放

mediaPlayer.seekTo(progress);

}

});

}

public void isPlayOrPause(View view){

//把View强转为ImageButton

ImageButton imageButton = (ImageButton) view;

if(mediaPlayer==null) {

//实例化MediaPlayer

mediaPlayer = MediaPlayer.create(this, R.raw.yao);

//开始播放

mediaPlayer.start();

//图标修改为暂停的图标

imageButton.setImageResource(android.R.drawable.ic_media_pause);

//获取音乐的总时长

int duration = mediaPlayer.getDuration();

//设置进度条的最大值为音乐的总时长

seekBar.setMax(duration);

new MyThre().start();

}//判断如果音乐在播放

else if(mediaPlayer.isPlaying()){

//就暂停音乐

mediaPlayer.pause();

//图标修改为播放的图标

imageButton.setImageResource(android.R.drawable.ic_media_play);

}else{

mediaPlayer.start();

//图标修改为暂停的图标

imageButton.setImageResource(android.R.drawable.ic_media_pause);

}

}

//写内部类

class MyThre extends Thread{

@Override

public void run() {

super.run();

while(seekBar.getProgress()<=seekBar.getMax()){

//获取当前音乐播放的位置

int currentPosition = mediaPlayer.getCurrentPosition();

//让进度条动起来

seekBar.setProgress(currentPosition);

}

}

}

}

2.播放内存卡中的音乐

package com.thm.g150820_android26_playmusic;

import android.media.AudioManager;

import android.media.MediaPlayer;

import android.net.Uri;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.ImageButton;

import android.widget.SeekBar;

import java.io.IOException;

public class MainActivity extends AppCompatActivity {

private MediaPlayer mediaPlayer;

private SeekBar seekBar;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

seekBar = (SeekBar) findViewById(R.id.seekBar);

seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

@Override

public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

}

@Override

public void onStartTrackingTouch(SeekBar seekBar) {

}

@Override

public void onStopTrackingTouch(SeekBar seekBar) {

//获取拖动结束之后的位置

int progress = seekBar.getProgress();

//跳转到某个位置播放

mediaPlayer.seekTo(progress);

}

});

}

public void isPlayOrPause(View view){

//把View强转为ImageButton

ImageButton imageButton = (ImageButton) view;

if(mediaPlayer==null) {

//实例化MediaPlayer

//播放应用内的音乐

//mediaPlayer = MediaPlayer.create(this, R.raw.yao);

//播放内存卡中的音乐

mediaPlayer = new MediaPlayer();

//设置类型

mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

//设置音乐路径

try {

mediaPlayer.setDataSource(this, Uri.parse("storage/sdcard0/Music/a.mp3"));

//播放之前准备一下

mediaPlayer.prepare();

} catch (IOException e) {

e.printStackTrace();

}

//开始播放

mediaPlayer.start();

//图标修改为暂停的图标

imageButton.setImageResource(android.R.drawable.ic_media_pause);

//获取音乐的总时长

int duration = mediaPlayer.getDuration();

//设置进度条的最大值为音乐的总时长

seekBar.setMax(duration);

new MyThre().start();

}//判断如果音乐在播放

else if(mediaPlayer.isPlaying()){

//就暂停音乐

mediaPlayer.pause();

//图标修改为播放的图标

imageButton.setImageResource(android.R.drawable.ic_media_play);

}else{

mediaPlayer.start();

//图标修改为暂停的图标

imageButton.setImageResource(android.R.drawable.ic_media_pause);

}

}

//写线程内部类

class MyThre extends Thread{

@Override

public void run() {

super.run();

while(seekBar.getProgress()<=seekBar.getMax()){

//获取当前音乐播放的位置

int currentPosition = mediaPlayer.getCurrentPosition();

//让进度条动起来

seekBar.setProgress(currentPosition);

}

}

}

}

3.添加读取内存的权限
