I tried registering onClickListener(), onKeyListener but I was not able to capture this? Thanks What can I register to detect this first click within the text editing area?

This can be done without listening for an event. In your EditText element in your layout.xml file, you can set an attribute android:hint.

<EditText 
  android:hint="Write Caption" <!-- This line -->
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content"/>

Maybe you should try using a focus listener.
