Question

I have a relative layout defined in a xml file(say realtive.xml). In another layout I have a relativelayout tag inside a linearlayout(say linear.xml). This realtive layout is empty and has an id say “rl”. On clicking a button in linear.xml, I want the contents of relative.xml to be set in the relative layout with id “rl”.
How should this be done?

Answer 1

In the onClick() method for that Button inflate the new layout and add it to that empty RelativeLayout:

RelativeLayout rl = (RelativeLayout) findViewById(R.id.rl);
getLayoutInflater().inflate(R.layout.realtive, rl, true);

Also if you don’t want to add the parent RelativeLayout from realtive.xml to the empty RelativeLayout then use the merge tag:

realtive.xml

<merge xmlns:android="http://schemas.android.com/apk/res/android">
   <!-- Here is the content of the realtive.xml without the parent RelativeLayout-->
</merge>
