用于实现类似音乐播放器通知栏功能（播放、暂停、上下一曲）
1、自定义通知栏
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "default"); builder.setSmallIcon(android.R.drawable.sym_def_app_icon); RemoteViews rv = new RemoteViews(getPackageName(), R.layout.message); rv.setTextViewText(R.id.tv, "泡沫");//修改自定义View中的歌名 //修改自定义View中的图片(两种方法) rv.setImageViewResource(R.id.iv, R.mipmap.ic_launcher); rv.setImageViewBitmap(R.id.iv, BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher)); builder.setContent(rv);//设置button监听为发送广播------------------ Intent previous = new Intent("com.example.Bean.MyBroadcastReceiver"); PendingIntent pi_previous = PendingIntent.getBroadcast(Tongzhi.this, 0, previous, PendingIntent.FLAG_UPDATE_CURRENT); rv.setOnClickPendingIntent(R.id.btn1, pi_previous);//---------------------------------------- Notification notification = builder.build(); NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notificationManager.notify(0x1, notification);<?xml version="1.0" encoding="utf-8"?> 2、自定义广播
public class MyBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "okgb", Toast.LENGTH_SHORT).show(); }}................ 发送这条广播测试广播是否注册成功
Intent integer = new Intent("com.example.Bean.MyBroadcastReceiver"); sendBroadcast(integer);
