I have created the Application in which i m Using MapView. Now i want to Use the Back Button in My that MapView. I have develop the Layout but it cant seen the开发者_StackOverflow社区 Button over mapview. When i push back button from Emulator then the Mapview become close and the Back button is shown. Can anybudy help me How to Show Back Button on the MapView. ? Thanks.

Bo basically it may be possible with the overlays but I have done it using RelativeLayout stuff

<RelativeLayout
    android:id="@+id/headerlayout" 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    >

    <Button android:id="@+id/amap_back_btn" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true" android:text="Back">
    </Button>

</RelativeLayout>

<MapViewActivity
    xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mapview"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:clickable="true" android:apiKey="your map key"
    android:layout_below="@+id/headerlayout"
    android:layout_above="@+id/bottomlayout" 
    />

You will need to use an overlay to add the back button on the MapView. Have a look at this tutorial which explains on how to add overlays. http://www.anddev.org/viewtopic.php?t=92
