as android default ,when you touch the sliding menu,it gets focused from back ground layout but i want to keep the background focused. for example like viber app when you touch the setting,it pushes the background away but both of them (sliding menu and background layout ) are focused. this is my xml for layouts:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
<FrameLayout
<RelativeLayout
<GridView
</GridView>
</RelativeLayout>
</FrameLayout>
<ListView
</android.support.v4.widget.DrawerLayout>
i found the answer. you should put this code in your main activity
mDrawerLayout.SetScrimColor(Android.Resource.Color.Transparent);
