c# - How to disable all touches for a Layout in Android -

i trying implement bottom sheet in xamarin.android , want disable touches on not bottom sheet (i.e. main layout), when bottom sheet active.

main.axml:

<framelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/main_layout"> <include     android:id="@+id/toolbar"     layout="@layout/toolbar" />  <!-- main layou --> <framelayout     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:id="@+id/main_content"     android:paddingleft="16dp"     android:paddingright="16dp" >     <button         android:id="@+id/btn_test"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:text="@string/logout"         android:layout_gravity="center" />     <android.support.design.widget.floatingactionbutton         android:id="@+id/fab"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="bottom|right"         android:layout_margin="16dp"         android:clickable="true"         android:src="@drawable/ic_plus" /> </framelayout>  <framelayout     android:id="@+id/tint"     android:background="#000000"     android:layout_width="match_parent"     android:layout_height="match_parent" />  <!-- bottom sheet --> <framelayout     android:id="@+id/bottom_fragment_container"     android:layout_width="match_parent"     android:layout_height="160dp"     android:background="#e0e0e0"     android:layout_gravity="bottom"     android:elevation="16dp"     android:translationy="160dp" /> 

i tried iterating on children , disabling them, changes appearance of button , want avoid that. tried setting enabled property of layout false, button still touchable.

i think need somehow intercept touches before reach button (and else there later), don't know how that. intercepting touches implement hiding of bottom sheet after touches.

create transparent relativelayout covers entire screen , use android:clickable="true" property in make sure intercepts click events.

then add android:layout_alignparentbottom bottom sheet , put inside newly created relativelayout. way it'll appear @ bottom , else won't clickable.

<framelayout>    <!-- main layout -->     <relativelayout      android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="#0000"     android:clickable="true">       <framelayout        android:id="@+id/bottom_fragment_container"        android:layout_width="match_parent"        android:layout_height="160dp"        android:background="#e0e0e0"        android:layout_alignparentbottom="true"        android:elevation="16dp"        android:translationy="160dp" />    </relativelayout>  </framelayout>
