I have imageview in my Android app that I am using like a button with the onClick event given, but as you might guess it is not giving imageview a clickable effect when clic
In combination with all the answers above, I wanted the ImageView to be pressed and changed state but if the user moved then "cancel" and not perform an onClickListener.
I ended up making a Point object within the class and setting its coordinates according to when the user pushed down on the ImageView. On the MotionEvent.ACTION_UP I recording a new point and compared the points.
I can only explain it so well, but here is what I did.
// set the ontouch listener
weatherView.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
// Determine what action with a switch statement
switch (event.getAction()) {
// User presses down on the ImageView, record the original point
// and set the color filter
case MotionEvent.ACTION_DOWN: {
ImageView view = (ImageView) v;
// overlay is black with transparency of 0x77 (119)
view.getDrawable().setColorFilter(0x77000000,
PorterDuff.Mode.SRC_ATOP);
view.invalidate();
p = new Point((int) event.getX(), (int) event.getY());
break;
}
// Once the user releases, record new point then compare the
// difference, if within a certain range perform onCLick
// and or otherwise clear the color filter
case MotionEvent.ACTION_UP: {
ImageView view = (ImageView) v;
Point f = new Point((int) event.getX(), (int) event.getY());
if ((Math.abs(f.x - p.x) < 15)
&& ((Math.abs(f.x - p.x) < 15))) {
view.performClick();
}
// clear the overlay
view.getDrawable().clearColorFilter();
view.invalidate();
break;
}
}
return true;
}
});
I have an onClickListener set on the imageView, but this can be an method.
