Question

我遇到了android leanback RowsFragment焦点的问题。我在相同的RowsFragment中添加了两种不同类型的适配器（下面附带代码）但是当按下向上按钮（电视遥控器DPad向上按钮）以获得焦点在上面的行时，焦点转到顶部栏导航。

//我的示例代码 -

MyRowFragment extends RowsFragment
    {
        private SparseArrayObjectAdapter myRowsAdapter;
        @Override
        public void onViewCreated (View view, Bundle savedInstanceState){
        super.onViewCreated(view, savedInstanceState);
        loadDataRows();
    }

    private void loadDataRows() {
// got some logic to download data 
        for (MyDataType data : MyDataTypeList) {
            ArrayObjectAdapter rowAdapter;

            //conditionToCheck is boolean to check some condition
            if (conditionToCheck) {
                rowAdapter =
                        new ArrayObjectAdapter(new MyCustomPresenter(value, value1));
            } else {
                rowAdapter =
                        new ArrayObjectAdapter(MyCustomPresentor1(value, value1));
            }

            rowAdapter.add(data);

            myRowsAdapter.set(rowKey, new ListRow(rowAdapter));

        }
    }
}

我的布局文件是：

<com.github.ksoichiro.android.observablescrollview.ObservableScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="none">

            <FrameLayout
                android:id="@+id/rowsContainer"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>
        </LinearLayout>
    </com.github.ksoichiro.android.observablescrollview.ObservableScrollView>

Answer 1

将焦点添加到MyCustomPresenter（）和MyCustomPresenter1（）中的卡片展示器。

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent) {
    cardView.setFocusable(true);
    cardView.setFocusableInTouchMode(true);
}

问题集中在RowsFragment android Leanback库？
