I am using this co

Answer 1

Access the EditTextPreference's EditText methods with getEditText and set the input type

EditTextPreference pref = (EditTextPreference) findPreference("pref_edit_text");
if (pref != null) {
    pref.getEditText().setInputType(InputType.TYPE_CLASS_NUMBER);
}

Unfortunate the offical library android.support.v7.preference hide access to getEditText, but there is a fix library that soloves this.
