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!!

You're trying to display a Toast in a background thread. You should do all your UI operations on the main UI thread. The exception RuntimeException: Can't create handler inside thread that has not called Looper. prepare() can be a little cryptic for beginners but essentially it tells you that you're in a wrong thread.
Custom toast views are deprecated. Apps can create a standard text toast with the makeText(android.
It is the string message that you want the toast to display on the Android Activity screen. String toastTextMsg = "Hello, welcome to Code2care!"; Toast toast = Toast. makeText(MainActivity. this, toastTextMsg , Toast.
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.
