将数据从 BroadcastReceiver 传递到服务

Question

我的目标是创建一个从广播接收器获取数据的方法。

我有一个注册 BroadcastReceiver 来监控电池插拔的服务。我如何从 BroadcastReceiver 获取数据？我想在此服务中接收数据 class:

服务：

public class myService extends Service {

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        registerReceivers();

        return START_NOT_STICKY;
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    private synchronized void registerReceivers() {

        IntentFilter chargeFilter = new IntentFilter( Intent.ACTION_POWER_CONNECTED );
        chargeFilter.addAction(Intent.ACTION_POWER_DISCONNECTED);

        registerReceiver(eCharge, chargeFilter);

    }
}

这是接收方：

public class EventCharge extends BroadcastReceiver {

    private static String TAG = "Event Charge";

    @Override
    public void onReceive(Context context, Intent intent) {

        String action = intent.getAction();
        int status = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
        boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||
            status == BatteryManager.BATTERY_STATUS_FULL;
        int chargePlug = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
        boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
        boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;

        String messagge = "PS: " + ((action == Intent.ACTION_POWER_CONNECTED) ? "C" : "D") + " [ usb: " + usbCharge + " ac: " + acCharge + " ]";

        Log.e(TAG, messagge );

    }
}

有解决办法吗？

Answer 1

在receiver中，你可以把所有的params放到一个Bundle中，然后使用包含那个bundle的startService(Intent)来调用目标服务。在服务中，您解析包并获取所有参数。

Answer 2

在广播接收器中，

    Intent intent = new Intent(Constants.BROADCAST_DETECTED_ACTIVITY);
   // Data you need to pass to activity
   intent.putExtra("type",Type);
   context.sendBroadcast(intent);

服役中，

registerReceiver(broadcastReceiver, new IntentFilter(Constants.BROADCAST_DETECTED_ACTIVITY));

BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.getAction().equals(BROADCAST_DETECTED_ACTIVITY)) {
        int type = intent.getIntExtra("type", 0);
      }
    }
};
