「BottomSheetBehavior を a の子ビューにアタッチすることでCoordinatorLayout(つまり、を追加するapp:layout_behavior=”android.support.design.widget.BottomSheetBehavior”)と、適切なタッチ検出が自動的に取得され、5 つの状態の間で遷移します...」. Linear LayouttoFrame Layoutを変更してみてください。

こんな感じで使ってみてください。

<FrameLayout
    android:id="@+id/bottom_sheet"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#ff0000"
    app:behavior_hideable="true"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior">

       <Button
            android:id="@+id/buildProjectButton"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/buildProject" />

        <Button
            android:id="@+id/buildTaskButton"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/buildTask" />


</FrameLayout>

コードを次のように変更します。

 View bottomSheet = findViewById(R.id.bottom_sheet);
 BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
 bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);


bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
    @Override
    public void onStateChanged(@NonNull View bottomSheet, int newState) {
        // React to state change
        Log.e("onStateChanged", "onStateChanged:" + newState);
        if (newState == BottomSheetBehavior.STATE_EXPANDED) {
               // Hide your state here.
        } 
    }

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

下部シートの動作は、デフォルトでは非表示にできません。これを追加する必要があります。

bottomSheetBehavior.setHideable(true);
