This blog post can help you understand the meaning of touch mode.

The most important part:

Touch mode is a state of the hierarchy of views, which depends solely on the user’s interaction with the phone. The touch mode itself is something very easy to understand, as it simply indicates whether there was a recent user interaction with the touch screen. For example, if you use a G1 phone, selecting a widget with a trackball will take you out of touch mode; however, if you touch the buttons on the screen with your finger, you will enter the touch mode. When the user is not in touch mode, we’re talking about trackball mode, navigation mode or keyboard navigation, so don’t be surprised if you come across these conditions. Finally, there is only one API directly related to touch mode, View.isInTouchMode ().

So android:focusableInTouchMode="true" means that the view can get focus when the phone is in touch mode.

Normally EditText usually focuses in touch mode, and on the other hand, a Button usually does not focus in touch mode.
