The logcat says: 06-17 11:55:19.280: ERROR/AndroidRuntime(359): *java.lang.NullPointerException* 06-17 11:55:19.280: ERROR/AndroidRuntime(359): at android.graphics.Canvas.drawRoundRect(Canvas.java:938) 06-17 11:55:19.280: ERROR/AndroidRuntime(359): at *com.es.TransparentPanel.dispatchDraw(TransparentPanel.java:53) * Your code calls canvas.drawRoundRect with something that's null.
Specifically, it's the paint object. It's null because you code doesn't call init() from the first constructor. And the first constructor is what's used for loading views from XML. Whenever you see the "Auto-generated constructor stub" comment, it's a hint to examine the code and make sure it makes sense. The "TODO" is there to remind about this, and shows in Eclipse's task view. -- Kostya 2011/6/17 ABSOLUT <[email protected]> > Many thanks!
