推荐答案

您可以检查列表用于Android用户界面小部件.要使用这些显式导航属性之一，请将其值设置为布局中另一个小部件的ID(android:id值).您应该将导航顺序设置为循环，以便最后一个控件将焦点引导回第一个.

You may check this documentation. The Android framework automatically applies a directional navigation scheme based on the relative position of focusable elements in your layouts. You should test the generated navigation scheme in your app using a D-pad controller. After testing, if you decide you want users to move through your layouts in a specific way, you can set up explicit directional navigation for your controls. Check the lists of all of the available navigation attributes for Android user interface widgets. To use one of these explicit navigation attributes, set the value to the ID (android:id value) of another widget in the layout. You should set up the navigation order as a loop, so that the last control directs focus back to the first one.
