Question

I have a screen which asks user to enter PIN.
I have 4 separate boxes & each box will have only one digit.
So I want to keep the Numeric keypad open through out the life of an activity.
I am able to force keypad open up on activity starts. But On presses back button it gets hidden.

Can you set this as part of your activity section on your manifest file :

android:windowSoftInputMode="stateAlwaysVisible"

you could try something like this :

public class EditView extends EditText {

    public EditView (Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    @Override
    public boolean onKeyPreIme(int keyCode, KeyEvent event) {
        return true;
    }
}
