Why doesn't the keyboard appear in Android:EditText?

Question

Android

I am writing a small program for Android. In the layout, upon clicking on the Button, a dynamic EditText is inserted. But on pressing in EditText the electronic keyboard does not open. If you change the orientation of the phone, then the EditText starts working normally, that is, the keyboard opens (in any orientation). How to fix?

Throw this idea))))

Answer 2

Once you form the EditText dynamically, you need to programmatically set the click behavior for it (for example, like this)
editText.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
v.requestFocus();
return false;
}
});
when flipping, the ifeys is redrawn and the event is pulled up by itself
