java - canvas bitmap animations without using a sprite sheet -

   bitmap[] planeframes = new bitmap[4];         protected void ondraw(canvas canvas) {     for(int = 0 ; < planeframes.length;i++)     canvas.drawbitmap(planeframes[i], plane.getcenterx(), 0, null); // planeframes array of bitmaps } 

im trying animate plane swapping images not working don't know if method simple work with

you can not animate way. ondraw called per draw iteration meaning whatever draw on canvas @ return what's going drawn on screen. you're doing here drawing bitmaps on canvas @ same spot , plastered on top of each other.

what need call invalidate() method of view. make things more efficient, can use rect or define areas around bitmaps.

@override protected void ondraw(canvas canvas) {     canvas.drawbitmap(planeframes[i], plane.getcenterx(), 0, null);     if(++i >= planeframes.length) {        = 0;     }     invalidate(bmprect); } 

this consistently draw through bitmaps while repeatedly drawing new bitmaps. last forever long view on screen. bmprect rect has coordinates of bitmap.
