clicked coordinate calculation error of eye icon

[nickwongwong]

When we use "padding" or "center_horizontal" of PasswordView, (getRight() - getCompoundDrawables()[2].getBounds().width()) will not show the true location of eye icon.
In this way, onTouchEvent can not handle the click event correctly.
Using getWidth() instead of getRight(), and getPaddingRight()

Having the same issue. If I use padding, the user can only toggle it by tapping the very end of the edit text field (i.e the last pixel)
Same results when using padding on either the TextInputLayout or directly on the PasswordView
