I have to drag some views on screen. I am modifying their position by changing left and top of their layout parameters from motion event on ACTION_MOVE from touch listener. Is there a way to "drag" items more smooth? Because tis kind of "dragging" is no smooth at all... Here is the code
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_DOWN:
dx = (int) motionEvent.getX();
dy = (int) motionEvent.getY();
break;
case MotionEvent.ACTION_MOVE:
int x = (int) motionEvent.getX();
int y = (int) motionEvent.getY();
RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) view.getLayoutParams();
int left = lp.leftMargin + (x - dx);
int top = lp.topMargin + (y - dy);
lp.leftMargin = left;
lp.topMargin = top;
view.setLayoutParams(lp);
break;
}
return true;
}
Try to use motionEvent.getRawX() and motionEvent.getRawY() instead of getY and getX
