add an existing XML layout programatically

Question

I'm going to create a new RelativeLayout with some Text and Image Views programatically and then add it to a parent layout. The question: is it possible to define that layout in XML and then just add it to the parent programatically? Would be a faster way..

Use inflation:

final LayoutInflater lyInflaterForPanel = (LayoutInflater) mContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout lLayoutPanel = (LinearLayout) lyInflaterForPanel.inflate(
                R.layout.my_row, null);

This has worked for me.

thx, it works. BUT, the layout that I did inflate has some TextViews. I initialized them after inflating the layout and tried to set the text, but it causes crashes. Any ideas how to fix that? – Droidman Nov 07 '12 at 12:42
I think it should work. Can you post logcat with your updated code? – MysticMagicϡ Nov 07 '12 at 13:20

it gives me a "Delivery Failure" error since I tried so set the text in the OnActivityResult() method (caused by NullPointerException). I did initialize the TextView after inflating its parent layout, but any action other then initialization (findViewById) causes a NullPointerException.. – Droidman Nov 07 '12 at 13:53

Use LayoutInflater class for that. It will covert your layout into a view and add it to parent.
