Linkage control of Android input box

* For some pages containing two input boxes and a confirmation button, such as login registration page, it is usually an account entry box, a password input box, and a confirmation button.
* When you click the second input box to eject the keyboard, the keyboard will often block the confirmation button, and we often ask for the confirmation button to be moved above the input box to avoid blocking the confirmation button.
* The following three classes implement this function, the code is independent, the usage is simple and quick
*
* 1. When an input box is entered:

* New Softinputoneedtctrl (your fragmentactivity). Register (view viewbaseline, view Viewtomove, EditText EditText);

* 2. Two input boxes:
* New Softinputtwoedtctrl (your fragmentactivity) register (view viewbaseline, view Viewtomove, EditText edt1, EditText EDIT2);
