please help me to make it possible

i have also tried to give max height/width to controls individually..but not working due to android:stretchColumns="*" want to keep fix spread/shrink for controls even if size of mobile resolution increase or decrease — Aditi K, Jan 14 '14 at 06:19
You need not specify the dp values to render a view properly in different screen densities. You can just use fill_parent which would serve the purpose. — Prem, Jan 14 '14 at 06:22
you have given 30dp and 75dp as width and height for all the screens. so it is going to show the same size in all the screen sizes. use generic valaues to get better views like fill_parent match_parent wrap_content like this — Tamilselvan Kalimuthu, Jan 14 '14 at 06:24
Refer to this link ... It tells you how to specify size conditions for imageview ... You can try the same for your layout. http://stackoverflow.com/questions/9914810/how-to-set-both-min-and-max-size-for-an-imageview-in-android Hope it helps — Prem, Jan 14 '14 at 06:24
