我已经创建自定义视图和包括里面fragment.but问题是地图触摸不工作，因为矩形视图完成warp_content后获得完整的屏幕分辨率。 当我绘制谷歌地图上方的可调整大小的矩形地图触摸不起作用。 这个主要活动XML，我想包括这个矩形视图。 请给我任何想法。 “com.My-application.activities.rectangle”是我添加这个类的包。实际上我想让两个工作在同一时间地图也滚动和矩形。 请推荐我正确的方法。因此，我可以解决我的问题。谷歌地图不工作时，包括其他视图android
在此先感谢。
这是我XML文件
<Relative-layout
android:id="@+id/inner_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="@+id/map_fragment"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<com.Myapplication.activities.rectangle
android:id="@+id/drawView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

返回false后，地图正在移动，但不是矩形。 – Umesh
@umesh你必须检测，如果触摸矩形边界。如果是 - 返回true，如果不返回false –
