This is the basic code. If you need a password keyboard (only numbers), add a callback for the addString parameter. Hiding the system keyboard cannot be hidden in the later version. In the end, I used another idea to directly disable the InputType pop-up of the system input method. TYPE_NULL, legacy problem: when the cursor locates the OnTouchListener, the cursor is positioned everywhere to be resolved.
