You can use a combination of a OnFocusChangeListener and a variable to indicate which EditText was last focused.

Lets say you have two EditText. You would add a OnFocusChangeListener to both. When the event fires, you just have to memorize which EditText received focus last. For example like this, using a class variable EditText lastFocused:

public void onFocusChange(View v, boolean hasFocus) {
    if(hasFocus)
        lastFocused = (EditText)v;
}

Then, when a user presses your button you simply do:

public void onClick(View v) {
    lastFocused.setText("Success!");
}
