Intercept back button from soft keyboard

Question

I have the activity with several input fields. When activity started soft keyboard is showed. When back button pressed soft keyboard closes and to close activity need to press back button one more time.

So the question: is it possible intercept back button to close soft keyboard and finish activity in one press of back button without creating custom InputMethodService?

P.S.: I know how intercept back button in other cases - onKeyDown() or onBackPressed() but in this case it's not works: only second press of back button is intercepted.

Answer 1

How are you showing the soft keyboard?

If you are using InputMethodManager.showSoftInput(), you can try passing in a ResultReceiver and implementing onReceiveResult() to handle RESULT_HIDDEN

Answer 2

Try this code in your BackPressed implementation(http://stackoverflow.com/questions/3988478/block-back-button-in-android/3988567#3988567):

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);

I suggest you to have a look @ http://stackoverflow.com/questions/1109022/how-to-close-hide-the-android-soft-keyboard

Answer 3

It seems there is no reliable way to do it:

1. Key events are eaten by soft keyboard.
2. There is no way (event) to know when soft keyboard is shown/hidden.
