java - Google Glass 全屏自定义布局卡

Question

我有一个问题。由于 Card 类已弃用并且 CardBuilder.EMBED_INSIDE 相当有限。唯一的选择是使用自定义 View 。我还想使用 CardScrollView 和 CardScrollAdapter。

访问Google Glass Immersion Custom Layout without CardBuilder.Layout.EMBED_INSIDE

但我的问题是，我不能有多个 View 。

这是 MyCustomViewClass:

   public class MyCustomView extends FrameLayout{
public MyCustomView (Context context) {
    super(context);
    initView();
}

private void initView()
{
    View view = inflate(getContext(), R.layout.imageview, null);
    addView(view);

    View view2 = inflate(getContext(), R.layout.secondview, null);
    addView(view2);
}

那是我的主要 Activity 课:

public class InspectionActivity extends Activity {

private CardScrollView mCardScroller;
private GestureDetector mGestureDetector;
private View mView;
private CardScrollView _cardScroller;
private ArrayList<View> _cardsList;
private MyCustomView _myView;
protected List<CardBuilder> mCards;
@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    createCards();
    _cardsList = new ArrayList<View>();
    _myView= new MyCustomView (this);
    _cardsList.add(_myView);
    _cardScroller = new CardScrollView(this) ;
    MainCardsScrollAdapter adapter = new MainCardsScrollAdapter(_cardsList);
    _cardScroller.setAdapter(adapter);
    _cardScroller.activate();
    setContentView(_cardScroller);
}

private void createCards() {
    mCards = new ArrayList<CardBuilder>();
}
public class MainCardsScrollAdapter extends CardScrollAdapter
{
    ArrayList<View> _cardsList;
    public MainCardsScrollAdapter(ArrayList<View> cardsList)
    {
        _cardsList = cardsList;
    }

    @Override
    public int getCount() {
        return _cardsList.size();
    }

    @Override
    public Object getItem(int i) {
        return _cardsList.get(i);
    }


    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        return _cardsList.get(i);
    }

    @Override
    public int getPosition(Object o) {
        return _cardsList.indexOf(o);
    }

    @Override
    public int getViewTypeCount() {
        return CardBuilder.getViewTypeCount();
    }

    @Override
    public int getItemViewType(int position){
        return 2;//should be changed, it's just an example
    }
} }

好吧，从你的帖子来看，我猜它只是将你的一个布局膨胀到 CardScrollView 中。尝试以下操作。

1. 创建一个看起来像这样的适配器类

   public class mainAdapter extends CardScrollAdapter {
   
      private List<CustomCard> mCards;
      private LayoutInflater inflater;
   
      public mainAdapter(List<CustomCard> cards, LayoutInflater inf)
      {
          this.mCards = cards;
          this.inflater = inf;
      }
   
      @Override
      public int getCount() {
          return mCards.size();
      }
   
      @Override
      public Object getItem(int i) {
          return mCards.get(i);
      }
   
      @Override
      public View getView(int i, View view, ViewGroup viewGroup) {
          int card = mCards.get(i).getLayout();
          view = inflater.inflate(card, viewGroup, false);
          return view;
      }
   
      @Override
      public int getPosition(Object o) {
          return this.mCards.indexOf(o);
      }
   }
   

我的 CustomCard 类看起来像这样，您可以只使用 List<Integer>相反

public class CustomCard {
    public int getLayout() {
        return layout;
    }

    public int layout;

    public CustomCard(int layout)
    {
        this.layout = layout;
    }
}

1. 在您的 Activity 类中创建并填充一个包含所需布局的列表，然后将它们传递给您的适配器，如下所示。

在onCreate()

CreateCards();
mCardScroller = new CardScrollView(this);
mCardScroller.setAdapter(new mainAdapter(mCards, getLayoutInflater()));

和 CreateCards()方法看起来像这样

public void CreateCards() {
        mCards.add(new CustomCard(R.layout.firstview));
        mCards.add(new CustomCard(R.layout.secondview));
        mCards.add(new CustomCard(R.layout.thirdview));
    }

希望对你有用
