Disabling User dragging on BottomSheet

Question

I am trying to disable user dragging on BottomSheet. The reason I want to disable is two things. 1. It's preventing the ListView from scrolling downward, 2. I don't want users to dismiss using dragging but with a button on the BottomSheetView. This is what I've done

 bottomSheetBehavior = BottomSheetBehavior.from(bottomAnc);     bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {         @Override         public void onStateChanged(@NonNull View bottomSheet, int newState) {             if (newState == BottomSheetBehavior.STATE_EXPANDED) {                 //Log.e("BottomSheet", "Expanded");             } else if (newState == BottomSheetBehavior.STATE_COLLAPSED) {                 //Log.e("BottomSheet", "Collapsed");             }         }          @Override         public void onSlide(@NonNull View bottomSheet, float slideOffset) {             // React to dragging events             bottomSheet.setOnTouchListener(new View.OnTouchListener() {                 @Override                 public boolean onTouch(View v, MotionEvent event) {                     int action = MotionEventCompat.getActionMasked(event);                     switch (action) {                         case MotionEvent.ACTION_DOWN:                             return false;                         default:                             return true;                     }                 }             });         }     }); 

The bottomSheetLayout

    <?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/white" app:behavior_hideable="true" app:behavior_peekHeight="0dp" app:layout_behavior="@string/bottom_sheet_behavior" android:id="@+id/bottomSheet">  <android.support.v7.widget.CardView     android:layout_width="match_parent"     android:layout_height="match_parent"     app:elevation="10dp">      <LinearLayout         android:layout_width="match_parent"         android:layout_height="match_parent"         android:orientation="vertical">          <LinearLayout             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:orientation="horizontal"             android:gravity="center_vertical">              <TextView                 android:id="@+id/text1"                 android:layout_width="0dp"                 android:layout_height="wrap_content"                 android:layout_weight="1"                 android:text="Order Items"                 android:layout_margin="16dp"                 android:textAppearance="@android:style/TextAppearance.Large"/>               <Button                 android:layout_width="50dp"                 android:layout_height="wrap_content"                 android:layout_marginRight="5dp"                 android:background="@drawable/bg_accept"/>              <Button                 android:layout_width="50dp"                 android:layout_height="wrap_content"                 android:layout_marginRight="8dp"                 android:background="@drawable/bg_cancel"/>          </LinearLayout>          <ListView             android:id="@+id/item_edit"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:background="@color/white"             android:divider="@color/md_divider_black"             android:dividerHeight="1dp"/>      </LinearLayout>  </android.support.v7.widget.CardView>

It can be now no longer relevant, but I will leave it here:

import android.content.Context import android.util.AttributeSet import androidx.coordinatorlayout.widget.CoordinatorLayout import android.view.MotionEvent import android.view.View import com.google.android.material.bottomsheet.BottomSheetBehavior  @Suppress("unused") class LockableBottomSheetBehavior<V : View> : BottomSheetBehavior<V> {     constructor() : super()     constructor(context: Context, attrs: AttributeSet) : super(context, attrs)      var swipeEnabled = true      override fun onInterceptTouchEvent(         parent: CoordinatorLayout,         child: V,         event: MotionEvent     ): Boolean {         return if (swipeEnabled) {             super.onInterceptTouchEvent(parent, child, event)         } else {             false         }     }      override fun onTouchEvent(parent: CoordinatorLayout, child: V, event: MotionEvent): Boolean {         return if (swipeEnabled) {             super.onTouchEvent(parent, child, event)         } else {             false         }     }      override fun onStartNestedScroll(         coordinatorLayout: CoordinatorLayout,         child: V,         directTargetChild: View,         target: View,         axes: Int,         type: Int     ): Boolean {         return if (swipeEnabled) {             super.onStartNestedScroll(                 coordinatorLayout,                 child,                 directTargetChild,                 target,                 axes,                 type             )         } else {             false         }     }      override fun onNestedPreScroll(         coordinatorLayout: CoordinatorLayout,         child: V,         target: View,         dx: Int,         dy: Int,         consumed: IntArray,         type: Int     ) {         if (swipeEnabled) {             super.onNestedPreScroll(coordinatorLayout, child, target, dx, dy, consumed, type)         }     }      override fun onStopNestedScroll(         coordinatorLayout: CoordinatorLayout,         child: V,         target: View,         type: Int     ) {         if (swipeEnabled) {             super.onStopNestedScroll(coordinatorLayout, child, target, type)         }     }      override fun onNestedPreFling(         coordinatorLayout: CoordinatorLayout,         child: V,         target: View,         velocityX: Float,         velocityY: Float     ): Boolean {         return if (swipeEnabled) {             super.onNestedPreFling(coordinatorLayout, child, target, velocityX, velocityY)         } else {             false         }     } } 

And use it in your xml file:

app:layout_behavior="com.your.package.LockableBottomSheetBehavior" 

It disables all users actions, it can be used when you want control BottomSheet only programmatically.
