Ⅲ android在线本地音乐播放器 简单点能看懂的 谁有源码给一个啊
下面这个例子是使用service和broadcastReceiver实现的简单音乐播放器，麻雀虽小，五脏俱全，网络搜索安卓无忧，点击源码看源码，你看演示：
packagemm.shandong.com.testsimplemedia;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.content.IntentFilter;
importandroid.support.v7.app.AppCompatActivity;
importandroid.os.Bundle;
importandroid.view.View;
importandroid.widget.ImageButton;
importandroid.widget.TextView;
importmm.shandong.com.testsimplemedia.service.MusicService;
{
ImageButtonimageButton;
TextViewtextViewMp3Name;
TextViewtextViewMp3Author;
intstatus=0;
String[]authors=newString[]{"张三","李四","王二"};
String[]names=newString[]{"first","second","thrid"};
intcurrentMusic=0;
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test_simple_media);
imageButton=(ImageButton)findViewById(R.id.imageButton);
textViewMp3Name=(TextView)findViewById(R.id.textViewMp3Name);
textViewMp3Author=(TextView)findViewById(R.id.textViewMp3Author);
imageButton.setOnClickListener(newView.OnClickListener(){
@Override
publicvoidonClick(Viewview){
Intentintent=newIntent("Get_Music_Control");
if(status==2){
intent.putExtra("control",0);
}else{
intent.putExtra("control",1);
}
sendBroadcast(intent);
}
});
IntentFilterintentFilter=newIntentFilter();
intentFilter.addAction("Update_Music_State");
=newMusicStatusReceiver();
//动态注册activity变化的广播接收者
registerReceiver(musicStatusReceiver,intentFilter);
Intentintent=newIntent(this,MusicService.class);
startService(intent);
IntentintentMusicReceiver=newIntent("Get_Music_Control");
intentMusicReceiver.putExtra("control",3);
sendBroadcast(intentMusicReceiver);
}
///上一首
publicvoidpreMusic(Viewview){
IntentintentMusicReceiver=newIntent("Get_Music_Control");
intentMusicReceiver.putExtra("control",4);
sendBroadcast(intentMusicReceiver);
}
///下一首
publicvoidnextMusic(Viewview){
IntentintentMusicReceiver=newIntent("Get_Music_Control");
intentMusicReceiver.putExtra("control",5);
sendBroadcast(intentMusicReceiver);
}
///定义操作音乐的广播接收者
{
@Override
publicvoidonReceive(Contextcontext,Intentintent){
status=intent.getIntExtra("status",0);
currentMusic=intent.getIntExtra("currentMusic",0);
switch(status){
case0:
textViewMp3Name.setText(names[currentMusic]);
textViewMp3Author.setText(authors[currentMusic]);
imageButton.setBackgroundResource(R.drawable.play32);
break;
case1:
textViewMp3Name.setText(names[currentMusic]);
textViewMp3Author.setText(authors[currentMusic]);
imageButton.setBackgroundResource(R.drawable.play32);
break;
case2:
imageButton.setBackgroundResource(R.drawable.pause32);
textViewMp3Name.setText(names[currentMusic]);
textViewMp3Author.setText(authors[currentMusic]);
break;
}
}
}
}

Ⅳ Android要求做一个一个简易音乐播放器。用Service实现
android开发培训一个简单的Android音乐播放器
在这里主要是用两个简单的按钮实现音乐的播放和停止功能，工程的目录结构为：
同时添加一个文件夹，里面放后缀为mp3的文件就可以了。 在main配置文件主要是添加两个Button：
添加一个activity类和一个service类AndroidManifest.xml配置文件为：
创建一个MusicServiceActivity类启动service类：中网互赢 手机客户端
Ⅳ android中扫描模拟器sd卡中mp3后缀的所有音乐文件，并显示到listView中，求源码或实现方法
Android系统会自动把添加到SD卡上的歌曲添加到一个SQLite数据库里 我们要做的就是把歌曲的信息从这个数据库里查询出来
查询SD卡上的mp3歌曲信息
Cursor mAudioCursor = this.getContentResolver().query(
MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,
null,// 字段没有字段就是查询所有信息相当于SQL语句中的“ * ”
null, // 查询条件
null, // 条件的对应?的参数
MediaStore.Audio.AudioColumns.TITLE);// 排序方式
// 循环输出歌曲的信息
List<Map<String, Object>> mListData = new ArrayList<Map<String, Object>>();
for (int i = 0; i < mAudioCursor.getCount(); i++) {
mAudioCursor.moveToNext();
// 找到歌曲标题和总时间对应的列索引
int indexTitle = mAudioCursor
.getColumnIndex(MediaStore.Audio.AudioColumns.TITLE);／／歌名
int indexARTIST = mAudioCursor
.getColumnIndex(MediaStore.Audio.AudioColumns.ARTIST);／／艺术家
int indexALBUM = mAudioCursor
.getColumnIndex(MediaStore.Audio.AudioColumns.ALBUM);／／专辑
String strTitle = mAudioCursor.getString(indexTitle);
String strARTIST = mAudioCursor.getString(indexARTIST);
String strALBUM = mAudioCursor.getString(indexALBUM);
HashMap<String, Object> nowMap = new HashMap<String, Object>();
nowMap.put("SongName", strTitle + "---" + strARTIST
+ "---" + strALBUM);
mListData.add(nowMap);
}
加载到ListView里就很简单了
