Greetings, I'm trying to draw a circle using onTouch event. What it should do is get the coordinates where screen is touched(ACTION_DOWN), and where touch is lift up(ACTION_UP). For drawing circles we have canvas.drawCircle(x,y,radius,paint); ..... Now radius should be equal to the area where user has lift the touch up(ACTION_UP)... It is not drawing like that.. Here is my code ..
*case MotionEvent.ACTION_DOWN:* * downx = event.getX();* * downy = event.getY();* * Log.d(TAG, "DOWN");* * break;* * case MotionEvent.ACTION_UP:* * upx = event.getX();* * upy = event.getY();* * choosenImageView.invalidate(); * * mode = NONE;* * Log.d(TAG, "mode=NONE");* * break;* * * * case MotionEvent.ACTION_MOVE:* * double temp = Math.pow((upx - downx), 2)* * + Math.pow((upy - downy), 2);* * float radius = (float) Math.sqrt(temp) / 2;* * canvas.drawCircle(downx, downy, radius, paint);* * Log.d(TAG, "DRAG");* * break;* Can any one help me???
