How to set maximum expanded height in android support design bottom sheet?

Question

I already showed my bottom sheet layout with its peek height set to 100dp. But how can I limit my bottom sheet to expand to 500dp only? This is my sample layout:

<android.support.design.widget.CoordinatorLayout android:id="@+id/coordinator" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent">  <fragment xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:id="@+id/map"     android:name="com.google.android.gms.maps.SupportMapFragment"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context=".MapsActivity" />  <android.support.v4.widget.NestedScrollView     android:id="@+id/design_bottom_sheet"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="#000000"     app:behavior_hideable="true"     app:behavior_peekHeight="100dp"     app:layout_behavior="android.support.design.widget.BottomSheetBehavior">      <LinearLayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical">          <TextView             android:layout_width="match_parent"             android:layout_height="100dp"             android:layout_marginBottom="5dp"             android:background="#e444ff" />          <TextView             android:layout_width="match_parent"             android:layout_height="100dp"             android:layout_marginBottom="5dp"             android:background="#e444ff" />          <TextView             android:layout_width="match_parent"             android:layout_height="100dp"             android:layout_marginBottom="5dp"             android:background="#e444ff" />      </LinearLayout>  </android.support.v4.widget.NestedScrollView>  <android.support.design.widget.FloatingActionButton     android:id="@+id/fab"     android:layout_margin="@dimen/activity_horizontal_margin"     app:layout_anchor="@+id/design_bottom_sheet"     app:layout_anchorGravity="top|right|end"     android:layout_width="wrap_content"     android:layout_height="wrap_content" />  </android.support.design.widget.CoordinatorLayout> 

In addition to my question, how can I disallow the user from dragging the bottom sheet up and down?

Answer 1

to stop the bottom sheet from moving up the full screen is simple, just set a layout_height for your NestedScrollView to 500dp, also you probably want to set it's layout_gravity="bottom"

<android.support.v4.widget.NestedScrollView     android:id="@+id/design_bottom_sheet"     android:layout_width="match_parent"     android:layout_height="500dp"     android:background="#000000"     android:layout_gravity="bottom"     app:behavior_hideable="true"     app:behavior_peekHeight="100dp"     app:layout_behavior="android.support.design.widget.BottomSheetBehavior">      <LinearLayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical">          <TextView             android:layout_width="match_parent"             android:layout_height="100dp"             android:layout_marginBottom="5dp"             android:background="#e444ff" />          <TextView             android:layout_width="match_parent"             android:layout_height="100dp"             android:layout_marginBottom="5dp"             android:background="#e444ff" />          <TextView             android:layout_width="match_parent"             android:layout_height="100dp"             android:layout_marginBottom="5dp"             android:background="#e444ff" />      </LinearLayout>  </android.support.v4.widget.NestedScrollView> 

if you don't want the view to be draggable up then you need to set behavior_peekHeight and layout_height to the same values.

And to stop the view from being draggable down is the behavior_hideable flag just set this to false
