android - change placing of child views dynamically using onDraw? -


is there way dynamically change position(like manually translation animation) on child view thats been defined , places inside onlayout?

i have onlayout defined here:

  @override     protected void onlayout(boolean changed, int left, int top, int right, int bottom) {          //place topview @ top of layout removing yspace value defined fro height         // of view , dividing height topview takes half space         // height of view container         topview.layout(0, 0, getwidth(), (getheight() - yspace) / 2);     }

i want manually change y axis position of topview dynamically .

i thinking ofabout ondraw ondraw doesnt childviews , draws them. instead gives blank canvas manually draw items in it.

currently implementing custom viewgroup takes x amount of child views , dynamically moves them around. question how move them around?
