I would like to roughly understand the amount of pressure that fingers press on a capacitive screen on Android. My idea is to cover the area covered by the finger when it is touched (maybe some additional parameters to get it more accurate, but this is the main idea).
So, is there any way to find that they are covered? (e.g. get the number of pixels covered).
There is only MotionEvent.getPressure () (which you probably already found). I doubt that there is something that reports how many pixels are covered by a finger.
I really don't know, but you have access to the following function:
MotionEvent e; float press = e.getPressure(...);
0 1, 0 = , 1 = , 1...
NIH... , ? , , !
You can use MotionEvent.getSize () to get the normalized value (0 to 1) from the screen area. This value correlates with the number of pixels clicked.
