Reuse a standard android attribute on my custom view

I am creating a custom compound view with the following layout

<merge xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:orientation="horizontal">

    <TextView
        android:id="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <EditText
        android:id="@+id/edit"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:inputType="text"
        android:singleLine="true"/>

</merge>

As you can see, it is simply a TextView and a EditText. I want to be able to provide attributes to my custom view that are forwarded on to either the TextView or EditText. For example

<codeguru.labelededittext.LabeledEditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:label="@string/label"
    app:hint="@string/hint"/>

I have figured out how to forward these string attributes to the TextView and EditText, repsectively:

    TypedArray a = context.getTheme().obtainStyledAttributes(attrs, R.styleable.LabeledEditText,
            0, 0);

    try {
        label.setText(a.getString(R.styleable.LabeledEditText_label));
        edit.setHint(a.getString(R.styleable.LabeledEditText_hint));
    } finally {
        a.recycle();
    }

Now I also want to set the inputType of the EditText. If I create a <attr name="inputType" format="flag"> tag, will I have to populate it with all the possible flag values? Is there a way to reuse the values already declared by EditText?

You can get this with:

int[] values = new int[]{android.R.attr.inputType};
TypedArray standardAttrArray = getContext().obtainStyledAttributes(attrs, values);
try {
    mInputType = standardAttrArray.getInt(0, EditorInfo.TYPE_NULL);
} finally {
    standardAttrArray.recycle();
}
