Java Dynamically adding Android Views android:Layout_toRightOf

I found this post really useful today:
http://stackoverflow.com/questions/2305395/laying-out-views-in-relativelayout-programmatically

ex.

RelativeLayout layout = new RelativeLayout(this);
TextView tv1 = new TextView(this);
tv1.setText("A");
tv1.setId(23);

TextView tv2 = new TextView(this);
tv2.setText("B");
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
lp.addRule(RelativeLayout.RIGHT_OF, tv1.getId());

layout.addView(tv1);       
layout.addView(tv2, lp);

******
you need to provide id's to your child views: tv1.setId(1); tv2.setId(2); Parent views do not automatically assign child views an Id, and the default value for an Id is NO_ID. Id's don't have to be unique in a view hiearchy - so 1, 2, 3, etc are all fine values to use - and you must use them for relative anchoring to work in RelativeLayout

Android screen capture

I found out how to use Eclipse to grab a screen capture of my android device. REALLY cool. No market app necessary.

1. Connect your phone to your computer
2. Open Eclipse
3. Click on the DDMS Perspective
4. Look at the Devices view
5. Click on your phone
6. Use the Menu Icon to Select > Screen Capture.
   
   
   
7. You'll see something like this:
   
   
   
   
8. Save your screen capture
