Answer 1

Try this use make your ScrollView android:fillViewport="true"

android:fillViewport="true"

Defines whether the scrollview should stretch its content to fill the viewport.

and in your manifest file add android:windowSoftInputMode="adjustResize" in your login activity

android:windowSoftInputMode="adjustResize"

The activity's main window is always resized to make room for the soft keyboard on screen

<activity
    android:name=".activities.LoginActivity"
    android:windowSoftInputMode="adjustResize"/>

Answer 2

Add in Your Scrollview :

android:fillViewport="true"

And Add in Your Manifest File :

android:windowSoftInputMode="adjustResize"
