Answer 1

One solution would be to extend a DialogPreference which allows the setting of a custom layout for the preference dialog. This way you have a preference listed and when you tap it, you get a dialog with your custom settings UI.

And the class

class MyPreference extends DialogPreference {
// along with constructors, you will want to override
    @Override
    protected void onBindDialogView(View view) {
        super.onBindDialogView(view);
        // view is your layout expanded and added to the dialog
            // find and hang on to your views here, add click listeners etc
            // basically things you would do in onCreate
        mTextView = (TextView)view.findViewById(R.Id.mytextview);
        }

        @Override
        protected void onDialogClosed(boolean positiveResult) {
           super.onDialogClosed(positiveResult);

            if (positiveResult) {
                // deal with persisting your values here
            }
        }
}

Obviously there are some other details, but this is the basic idea.
