Why am I able to click "behind" the bottomsheet in Android?

Question

I have a BottomSheet in my Activity.

I'm calling behavior.setState(BottomSheetBehavior.STATE_EXPANDED); to show the bottom sheet and it works fine, but the problem I have is that I can somehow click on the empty space of my bottom sheet to trigger onClick event of a view that is behind the bottom sheet.

Is there a way to prevent this from happening?

What version of the Support Library are you using? Have you upgraded to the latest (24.2.1 as of now)? — ianhanniballake, Sep 27 '16 at 22:38
I found an exact same question that was asked here http://stackoverflow.com/questions/37596701/dim-screen-and-block-interaction-with-bottomsheets but doesnt seem to have an answer yet — user1865027, Sep 27 '16 at 22:55
the project I'm working on has switched to AndroidX and I couldn't reproduce clicking through the Bottom Sheet — Someone Somewhere, Jun 13 '20 at 01:28

A simple solution is to add the

android:clickable="true"

attribute to the layout that you are using for your bottom sheet. That way it will capture all clicks, and not let them bleed through. You do not have to set an onClick method for it, as you have no need to handle them.

Please post the layout. – lionscribe Sep 29 '16 at 02:26
if `android:clickable="false"` doesn't work, try to `setEnable(false)` on the clickable controls below the buttonsheet when the bottom sheet is expanded. Use `slideOffset`to get the slide direction – GGK stands for Ukraine Jan 14 '20 at 22:05
You can also set `bottomSheet.setClickable(false);`in Your code – GGK stands for Ukraine Jan 14 '20 at 22:13
The answer works out fine, but I didn't understand the logic. Could you please help me understand? – Nishchay Zacariah May 16 '21 at 10:42

@NishchayZacariah If a view is not clickable, it will allow the touch to go to the view under it. For example, you may have an imageView in a button, but since it is not clickable, it allows the click to go through to the button below it. – lionscribe May 26 '21 at 20:52

I faced same issue !

Add android:clickable=true to your BottomSheet ! Should look like below !

<LinearLayout
    android:clickable="true"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/materialWhite"
    android:orientation="vertical"
    app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">
</LinearLayout>

Why am I able to click "behind" the bottomsheet in Android?
