I am trying to change the height of linear layout programmatically. When I use 

ll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

I am getting exception:

My guess is you're importing a different LayoutParams. Try a fully qualified version:

ll.setLayoutParams(new android.view.ViewGroup.LayoutParams(
    android.view.ViewGroup.LayoutParams.FILL_PARENT,
    android.view.ViewGroup.LayoutParams.WRAP_CONTENT
));

I got the solution LinearLayout.LayoutParams class as 

ll.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

When you first include LayoutParams in your code and hit Cntrl+Shift+Enter to automatically import the required files, you are displayed a list of all the packages. Make sure you import the right package in your code.

import android.view.ViewGroup.LayoutParams;
