Answer 1

use following ,

for small screen

res/layout/layout.xml         
/res/layout-land/layout.xml 

for large screen like tablets you can use,,

/res/layout-large-hdpi/layout.xml   
/res/layout-land-large-hdpi/layout.xml

these two representations are enough and it can fit to all devices

layout-land is for landscape mode for smaller devices and layout-land-large-hdpi for large devices,

and add these lines to your manifest.xml

<supports-screens android:anyDensity="true" 
    android:largeScreens="true" 
    android:normalScreens="true"
    android:smallScreens="true" 
    android:xlargeScreens="true" />

Answer 2

Add This code in XML file before compiling the app
    <supports-screens android:anyDensity="true" 
    android:largeScreens="true" 
    android:normalScreens="true"
    android:smallScreens="true" 
    android:xlargeScreens="true" />
