Question

I have a bitmap and I draw it like this :

bit = BitmapFactory.decodeResource(getResources(),
                   R.drawable.anim_ctrl_panel);
Paint paint = new Paint();
canvas.drawBitmap(bit, 80, 440, paint);

The problem is that the image is set as fullscreen .On onTouchEvent method I implement the event for the bitmap and anywhere I select screen the event is implement. I want the image to have a certain position and only for that position to be implement the event. How can I do this?

EDIT: the problem was at onTouchEvent method. This is the solution :

public boolean onTouchEvent(MotionEvent event) {if(80 <= event.getX() && event.getX()<= (80+bit.getWidth()/2) && (440 <= event.getY() && (event.getY() <= 440+bit.getHeight()))){   
            //...
        }else if((80+bit.getWidth()/2) <= event.getX() && event.getX()<= (80+bit.getWidth()) && (440 <= event.getY() && (event.getY() <= 440+bit.getHeight()))){
            //...
            }

this help me : How can I check the Image is Touched using OnTouch()

Answer 1

For Image set in particular area, I think Rectangle is useful for this,

Something like this, (In my case Its work for me)

Canvas canvas = new Canvas(bitmap);
final Paint paint = new Paint();         
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());         
paint.setAntiAlias(true);         
canvas.drawARGB(0, 0, 0, 0);         
canvas.drawBitmap(bitmap, rect, rect, paint);

Try it.
