android自定义通知栏并通过广播实现监听

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);

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);
