how to set height of relative layout dynamically in android

Question

This is working fine on emulator but not on the devices because I have hard coded the height to 365. Can anyone help me in this regard?

Answer 1

You can change the layout height dynamically through different ways-----

First,

getLayoutParams().height= x;
requestLayout(); or invalidate(); 

Secondly,

 first_tab.setHeight(int pixels);

Try using anyone of the way.......

Answer 2

You should not use px, use dp instead.

android:layout_height="365dp"

Have a read here, to know Density independent pixel(dp) better.

Using dp units to define your application's UI is highly recommended, as a way of ensuring proper display of your UI on different screens.
