I am using the support FloatingActionButton Snackbar CoordinatorLayout I need the CoordinatorLayout so that if SnackBar is shown the FloatingActionButton moves up to make room for the Snackbar. For better understanding check this video . I am using SnackBar for double-back to exit the application, but the SnackBar can be dismissed. Is there a way to disable the dismiss on the SnackBar? Snackbar snackbar = Snackbar.make(view, R.string.press_back_again_to_exit, Snackbar.LENGTH_SHORT); snackbar.setAction(R.string.ok, new View.OnClickListener() { @Override public void onClick(View v) { } });

How can the background be dimmed just like it is shown here ? I've set it up normally using the CoordinatorLayout and the BottomSheetBehavior . This will simply show a bottom sheet. public class MyBottomSheet extends BottomSheetDialogFragment { private static final String TAG = "MyBottomSheet"; @NonNull @Override public Dialog onCreateDialog(final Bundle savedInstanceState) { final BottomSheetDialog dialog = (BottomSheetDialog) super.onCreateDialog(savedInstanceState); final View view = View.inflate(getContext(), R.layout.my_custom_view, null); dialog.setContentView(view); behavior =

Introduction I have an activity, which implements a common pattern with parallax header image and scrolling content using CoordinatorLayout , AppBarLayout and CollapsingToolbarLayout . My xml layout looks like this: <android.support.design.widget.CoordinatorLayout android:fitsSystemWindows="true" android:layout_height="match_parent" android:layout_width="match_parent"> <android.support.design.widget.AppBarLayout android:fitsSystemWindows="true" android:id="@+id/appbar" android:layout_height="wrap_content" android:layout_width="match_parent" android:theme="@style/AppTheme.AppBarOverlay">

So when I scroll to bottom i see this: main layout code: <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/coordinator" android:layout_width="match_parent" android:layout_height="match_parent" android

I'm trying to get the toolbar to collapse on scroll when a recyclerview inside a fragment is scrolled. To start, heres my main layout: <DrawerLayout> <RelativeLayout android:id="@+id/mainRelativeLayout" android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.design.widget.CoordinatorLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <android.support.design.widget.AppBarLayout android:id="@+id/appBarLayout" android:layout_width="match_parent" android:layout_height="wrap_content" > <Toolbar android:id="@+id/toolbar" android

In the GIF below you'll see I'm having trouble coordinating (heh) an AppBarLayout , containing a CollapsingToolbarLayout , and a Persistent BottomSheet in such a way that they play nicely together Goal: Have the fragment contents , seen above in turquoise ( #26999f ), remain above, yet scroll behind, the BottomSheet, seen above in dark green (#12783e) , while also respecting the AppBarLayout and its Behavior Again, as you can see from the GIF I'm close; the fragment contents is using a custom layout_behavior , MyScrollingViewBehavior , which extends AppBarLayout.ScrollingViewBehavior In the
