Hello palak1302,

remember that onDraw(...) gets called every single time your View gets invalidated!
Are you sure you have to setAdapter every time :?:

Hello palak1302,

you've had a look at the Gallery-Tutorial :?:

Code there is working well.

Second thing there is you are drawing to "mcanvas" but the canvas visible to the user is the canvas that is coming in as the parameter "canvas".
