How to set maximum expanded height in android support design bottom sheet?
You can use setMaxHeight method from BottomSheetBehavior
(this method should be called before show()
method)
bottomSheetDialog.behavior.maxHeight = 1000 // set max height when expanded in PIXEL
bottomSheetDialog.behavior.peekHeight = 400 // set default height when collapsed in PIXEL
You can just set param "maxHeight" to the root viewgroup of your bottom sheet.
android:maxHeight=500dp
Works good with ConstraintLayout as root layout.
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
