OnCreate方法不断调用OnResume方法

Question

So i have this app and everytime i start the main activity the OnResume method gets called.i have put a Toast message in both the OnCreate and OnResume methods and everytime i start the Activity both Toasts show. Is there something i am missing here? I have looked at the code line by line but found nothing that might be causing this.

Answer 1

OnResume() is called everytime in the lifecycle of an activity. See the picture below. Add onResume() only when you need to do some task if app is to started from background or from paused state.

Answer 2

You need to create some condition and call recreate only if that condition is satisfied. assign a boolean variable if your condition is satisfied and call recreate if this boolean is true or false as per your condition, Otherwise your loop will never stop.

private boolean isCheck = false;
onCreate() {
    if(somecondition == true) {
        isCheck = true;
    }
}

onResume() {
    if(!isCheck){
        recreate();
    }
}
