ich auch Probe meiner Layout liefern Es ist wie es aussehen wird .. Bilder sind nur unterschiedlich ..
Ich möchte Linien zeichnen, wo zwei Bilder gleich sind.Es kann sein, Cross-Linie aber es sollte gerade sein.
Mögliche Duplikate von [Wie zeichne ich eine Linie zwischen zwei ImageButtons in Android?] (Http://stackoverflow.com/questions/23925847/How-Do-ich-zeichne-eine-Linie-zwischen-zwei-Bild-Buttons-in-android) –
