Android: Edit Text Go Button

You want a combination of android:imeOptions and setOnEditorActionListener

<EditText android:id="@+id/some_edittext"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:imeOptions="actionSend">
</EditText>


some_edittext.setOnEditorActionListener(new OnEditorActionListener() {
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEND) {
            some_button.performClick();
            return true;
        }
        return false;
    }
});

Obviously you should change actionSend to the action you want, and update IME_ACTION_SEND correspondingly.
