Question

我在Android应用中显示解析数据时遇到了一些麻烦。基本上，我有两个API。第一个包含特定内容的ID。我已经解析并存储链接ID作为变量来调用下一个API以获取一些特定内容。数据已经过解析，但我想在CardView中正确显示，但目前显示如下。

绿色的单词应该低于它各自的标题。

这是我正在使用的代码。我会感谢任何帮助以某种方式解决这个问题。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    final View rootView = inflater.inflate(R.layout.fragment_newsfeed, container, false);


    Context context = getActivity();


    cardView = (CardView) rootView.findViewById(R.id.cv);
    rv = (RecyclerView) rootView.findViewById(R.id.rv);


    mSwipe = (SwipeRefreshLayout) rootView.findViewById(R.id.swipeRefreshLayout);
    mSwipe.setColorSchemeColors(R.color.primary, R.color.accent);
    mSwipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {


        @Override
        public void onRefresh() {


            refreshContent();
        }

Answer 1

让我假设并猜测您将CardView下的所有内容都归咎于错误，因为CardView是FrameLayout的一个实例，它将重叠所有内容。我的建议是将layout更改为

CardView>LinearLayout{(Vertical)[views within]}

在RecyclerView中显示已解析的数据（使用Volley）
