android:fitsSystemWindows not working on Fragment

Question

I have a fragment call reload fragment below. Parent activity is MainActivity. I attached manifest file code which related to activity. When I click in the edittext bottom buttons cover edittext fields with the keyboard. I added android:fitsSystemWindows property in the manifest file. Is there anything missing in my code?

                android:name=".ui.main.MainActivity"
                android:screenOrientation="sensorPortrait"
                android:theme="@style/AppTheme.NoActionBar"></activity>

Answer 1

activity?.window?.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN)

Answer 2

Adding android:fitsSystemWindows="true and android:windowSoftInputMode="adjustResize" to the Main Activity won't work.

You have to add android:fitsSystemWindows="true to the parent layout of that particular Fragment xml file. And in the java class of the Fragment in your onCreateView you have to add windowSoftInputMode like this.

getActivity()
            .getWindow()
            .setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

Hope this works for you. Let me know if you have any issue.
