Layout orientation in code

Question

I have this code in my application:

LinearLayout.LayoutParams params =     new LinearLayout.LayoutParams(WRAP_CONTENT, WRAP_CONTENT); 

and I just want to set the orientation of the LinearLayout to vertical. The equivalent in XML is:

android:orientation="vertical" 

How can I do it in the code, without XML?

Answer 1

You can't change LinearLayout's orientation using its LayoutParams. It can be done only with a LinearLayout object.

LinearLayout layout = /* ... */; layout.setOrientation(LinearLayout.VERTICAL); 

Answer 2

You can use like this one:

LinearLayout myll = (LinearLayout) findViewById(R.id.yourLinearLayout); myll.setLayoutParams(new LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT)); myll.setOrientation(LinearLayout.VERTICAL);
