This is the basic code, if you need a password keyboard (pure number), add a callback for the addstring parameter. Hide the system keyboard in the high version can not hide, and finally replaced a way of thinking, directly prohibit the system input method pop-up Inputtype.type_null, legacy issues: Cursor positioning Ontouchlistener When the cursor positioning everywhere to solve the position
