4. 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;
}
}
}
}

5. android 添加背景音乐源码

一张你从伍迹手未填写过的巨额支票，
枯黄萎缩州旦的败叶，
不要去做，孩子
浪来时，你指着海洋彼岸
也会让有些人感到烦扰。
他腔嫌来的这中，哈哈
