How to set focus to a button widget programmatical

问题:

Is it possible to set a focus to a button widget which lies somewhere down in my layout? onCreate of the activity my control/focus should be on that button programmatically.

回答1:

Yeah it's possible.

Button myBtn = (Button)findViewById(R.id.myButtonId);
myBtn.requestFocus();

or in XML

<Button ...><requestFocus /></Button>

Important Note: The button widget needs to be focusable and focusableInTouchMode. Most widgets are focusable but not focusableInTouchMode by default. So make sure to either set it in code

myBtn.setFocusableInTouchMode(true);

or in XML

android:focusableInTouchMode="true"

回答2:

Try this:

btn.requestFocusFromTouch();
