By reading this: android.widget.LinearLayout$LayoutParams cannot be cast to android.widget.FrameLayout$LayoutParams
I'd say you need to change this: msettingsLayout.setLayoutParams(new LinearLayout.LayoutParams(settingsw, settingsh)); into: msettingsLayout.setLayoutParams(new *FrameLayout*.LayoutParams(settingsw, settingsh)); This is most probably because your LinearLayout msettingsLayout is inside a FrameLayout, and so its layout params must be of its parent class.
