Android Spinner Size very large

Question

I'm trying to get an ICS spinner like in my app, and playing around for hours, finally I'm using HoloEverywhere to get this, and it's working, but I have a little disign issue, is that the spinner is not wrapping its content as I set in the xml, and by default looks like this :

Really I googled this for hours, and all I found is that how to resize spinner items and not the view itself, means that I want the spinner to be adjusted to the selected item size like this :

Here is my XML:

<RelativeLayout 
android:layout_width="match_parent"
android:layout_height="40dp"
android:orientation="horizontal" >

<org.holoeverywhere.widget.Spinner
    android:id="@+id/spnCities"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="10dp"
    />

<TextView
    android:id="@+id/tvCities"
    android:layout_width="70dp"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_centerVertical="true"
    android:layout_marginLeft="10dp"
    android:text="@string/city"
    android:textAppearance="?android:attr/textAppearanceSmall" />

</RelativeLayout>

Spinner have max width his items, but at most a parent width (on layout_width = wrap_content). You may create CustomSpinner class in org.holoeverywhere.widget package and override method measureContentWidth:

@Override
int measureContentWidth(SpinnerAdapter adapter, Drawable background) {
    if (adapter == null) {
        return 0;
    }
    View view = adapter.getView(getSelectedItemPosition(), null, this);
    if (view.getLayoutParams() == null) {
        view.setLayoutParams(new ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.WRAP_CONTENT,
                ViewGroup.LayoutParams.WRAP_CONTENT));
    }
    view.measure(MeasureSpec.makeMeasureSpec(0,
            MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0,
            MeasureSpec.UNSPECIFIED));
    int width = view.getMeasuredWidth();
    if (background != null) {
        Rect mTempRect = new Rect();
        background.getPadding(mTempRect);
        width += mTempRect.left + mTempRect.right;
    }
    return width;
}

This also worked for me ! Creating your own CustomSpinner and just implemeting that method (without the override) and using ir in your app the width of the item selected just has his real with :) in previous versions the spinner by default do this, at least 2.3 – Baumbaugh
