Toast.setGravity() does not work in my AVD Nexus 6 API 30

Question

I set the gravity of my toast to make it show on the top of the screen, with code below：

Toast toast = Toast.makeText(getActivity(), "邮箱地址不能为空！", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.TOP, 0, 0);
toast.show();

it does not work in my AVD Nexus 6 API 30 with LogCat message:

E/Toast: setGravity() shouldn't be called on text toasts, the values won't be used

however it seems fine when I install the apk on my phone Nokia X6 with Android 9. please help me!!

Answer 1

As it said in Android documentation about Toast setGravity method, this method doesn't work anymore for devices running API30 or higher. I suppose you have targetSdk set to 30 for your project.

Warning: Starting from Android Build.VERSION_CODES#R, for apps targeting API level Build.VERSION_CODES#R or higher, this method is a no-op when called on text toasts.
