android – Bottom Sheet行为只需要在按钮点击时显示？

我已经使用appcompat-v7实现了底页：23.2.1.一切正常,但唯一的问题是,当我向上拖动布局时,底部工作表出现.我不希望在向上拖动时显示底部工作表在底部工作表未显示在屏幕上时的布局上.

<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/DarkGray"
tools:context=".bottom_sheets.grid.BottomSheetGridActivity">
  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <Button
        android:id="@+id/btnView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Show view" />
  </LinearLayout>
   <LinearLayout
    android:id="@+id/bottom_sheet1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="vertical"
    android:layout_marginBottom="8dp"
    app:layout_behavior="@string/bottom_sheet_behavior">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clipToPadding="false"
        android:background="#fff"
        />
 </LinearLayout>
</android.support.design.widget.CoordinatorLayout>

主要活动

  @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.bottom_grid);
    Button btnView = (Button) findViewById(R.id.btnView);
    View bottomSheet = findViewById(R.id.bottom_sheet1);
    behavior = BottomSheetBehavior.from(bottomSheet);
    btnView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

             behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
        }
    });

    behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            // React to state change

        }

        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {
            // React to dragging events
        }
    });

    RecyclerView listRecyclerView = (RecyclerView) findViewById(R.id.recyclerView1);
    listRecyclerView.setHasFixedSize(true);
    listRecyclerView.setLayoutManager(new LinearLayoutManager(this));
    RecyclerItemAdapter recyclerItemAdapter = new RecyclerItemAdapter(createItems(), this);
    listRecyclerView.setAdapter(recyclerItemAdapter);
}

上面的代码将在点击时显示底部工作表,但是在布局上拖动时也会显示工作表.有什么我错过了.请帮助我！

解决方法:

谢谢@oguzhand

 behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            // React to state change
            if (newState == BottomSheetBehavior.STATE_DRAGGING) {
                behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
            }
        }

        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {
            // React to dragging events
        }
    });

我现在可以在未显示时禁用底页行为.
