Multiple layout type like

layout-large-mdpi   
layout-large-tvdpi  
layout-large-xhdpi 
layout-xlarge-mdpi  
layout-xlarge-xhdpi 

Answer 1

Using different dimens files you can do this thing.

values-mdpi ->dimens.xml

values-hdpi ->dimens.xml

values-xhdpi ->dimens.xml

values-xxhdpi ->dimens.xml

For example: define one in values-mdpi ->dimens.xml

<dimen name="scale_1dp">10dp</dimen>

and for values-hdpi ->dimens.xml

<dimen name="scale_1dp">12dp</dimen>

and for values-xhdpi ->dimens.xml

<dimen name="scale_1dp">15dp</dimen>

And after that use this dimen

<ImageView
     android:layout_width="@dimen/scale_1dp"
     android:layout_height="wrap_content"
     android:layout_gravity="center"/>

same thing for text size.
