Android-TV：两个listview焦点切换时焦点如何回到离开之前的item上面

 布局用这个就可以了，就是添加了一个onFocusChanged方法

public class myListView extends ListView {
    public myListView(Context context) {
        super(context);
    }

    public myListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public myListView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    public myListView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }


    @Override
    protected void onFocusChanged(boolean gainFocus, int direction, Rect previouslyFocusedRect) {
        int lastSelectItem = getSelectedItemPosition();
        super.onFocusChanged(gainFocus, direction, previouslyFocusedRect);
        if (gainFocus) {
            setSelection(lastSelectItem);
        }
    }

}

使用

        <cn.titansys.waylon.ui.listview.myListView
            android:background="#60000000"
            android:id="@+id/lv_list"
            android:layout_width="200dp"
            android:layout_marginBottom="200px"
            android:layout_marginLeft="100px"
            android:layout_height="800px"
            android:listSelector="@drawable/item_focus_sub_left" />
