Well, you can use this to go from identifier-as-a-string to identifier-as-a-number:
http://developer.android.com/reference/android/content/res/Resources.html#getIdentifier(java.lang.String, java.lang.String, java.lang.String) Another option is to specify tags for your buttons with android:tag="blahblahblah" in the XML, and then use View.findViewWithTag: http://developer.android.com/reference/android/view/View.html#findViewWithTag(java.lang.Object) I understand that neither option is very fast, so use carefully (cache the results in a more directly accessible data structure). -- Kostya 20 марта 2012 г. 20:08 пользователь Bozzified <[email protected]> написал: > Oh, yeah I can do that.
