ZoomInAnimation cover other view

What steps will reproduce the problem?
1.I add tow mapview in a Activity. Layout.xml like this.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    tools:context=".MainActivity" >

    <com.mutu.mapapi.views.MapView
        android:id="@+id/mapview1"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        tilesource="tianditu_yunnan_vector"
        />

    <com.mutu.mapapi.views.MapView
        android:id="@+id/mapview2"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        tilesource="tianditu_yunnan_image"
        />

</LinearLayout>
2.zoom in. mapview2 will cover mapview1.
3.

What is the expected output? What do you see instead?
mapview2 not cover mapview1 when zoominAnimation 

What version of the product are you using? On what operating system?
osmdroid 3.0.10 (i added some tilesource)
android 4.1.3
