sub class 에서 localbroadcaster로 main call 하기

LocalBroadCast를 이용해서 mainActivity Call

 

mainActivity.java에 statusReceiver define

LocalBroadcastManager.getInstance(this).registerReceiver(
        statusReceiver, new IntentFilter("STATUS_CHANGED"));

 

sub class에서 main call 

Intent intent = new Intent("STATUS_CHANGED");
intent.putExtra("status", canShake);
LocalBroadcastManager.getInstance(context).sendBroadcast(intent);

 

mainActivity에서 response 대응

private final BroadcastReceiver statusReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        // Receive the status change
        boolean status = intent.getBooleanExtra("status", true);
        if (isShake) {
            leftV.setVisibility(View.VISIBLE);
            rightV.setVisibility(View.VISIBLE);
            isShake = false;
        }
    }
};
