仅使用意图来发送数据而无需转到其他类别/活动

Question

I have a method set up to send data to my MainActivty:

public void sendPlayerDataMethod() {
    String testt = "thissss is for testing";
    Intent sendPlayerData = new Intent(this, MainActivity.class);
    sendPlayerData.putExtra(Intent.EXTRA_TEXT, testt);
    startActivity(sendPlayerData);
}

Every time this method is called, it then takes the user to the MainActivity, as coded but how do I get it to just send the data without moving to another activity?

Thanks

Answer 1

What I understand from what you wrote : You have an activity called MainActivity it is open and you are trying to send data to it from another activity.

Try this if this suits your case :

Add this to your MainActivity in your manifest : android:launchMode="singleTask" This will prevent your activity from instantiating again and again.

Override this method on your MainActivity

@Override
protected void onNewIntent(Intent intent){
   super.onNewIntent(intent);
   //get and use your extra data
}

now when you call your activity via an intent, this onNewIntent method will be fired. Get your extra data there.

Hope it helps.
