android - Android Retrofit：如何仅将 JSON 数据显示到一个卡片视图中？

Question

我在显示我的输出时遇到了最后一个问题。我想要的是每个语法错误都会有一个消息和每个卡片视图的建议列表。

这是我在结果适配器中的代码：

public class ResultAdapter extends RecyclerView.Adapter<ResultAdapter.ResultViewHolder>{

Context mContext;
List<Photo> photoList = new ArrayList<>();
ArrayList<Match> matchList = new ArrayList<>();
ArrayList<Replacement> replacementList = new ArrayList<>();
ArrayList<Object> data = new ArrayList<>();

int VIEW_TYPE_MATCH = 1;
int VIEW_TYPE_REPLACEMENT = 2;
public ResultAdapter (Context mContext, ArrayList<Match> matchList){
    this.mContext = mContext;

    for (int a =0; a < matchList.size(); a++){

        for (int b = 0; b < matchList.get(a).getReplacements().size(); b++){
            this.data.add(matchList.get(a));
            this.data.add(matchList.get(a).getReplacements().get(b));
        }


        Log.i("Adapter", "Replacement " + matchList.get(a).getReplacements().size());
    }


    Log.i("Adapter", "MatchList " + matchList.size());

}


@Override
public ResultViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext())
            .inflate(R.layout.result_card, viewGroup, false);
    getViewType(i);
    return new ResultViewHolder(view);
}

@Override
public void onBindViewHolder(ResultViewHolder resultViewHolder, int i) {

    Object value = data.get(i);
    if (value instanceof Match) {
        Match match = (Match) value;
        resultViewHolder.mBadErrorTextView.setText(match.getMessage());
    } else {
        Replacement replacement = (Replacement) value;
        resultViewHolder.mBetterErrorTextView.setText(replacement.getValue());
    }
}

@Override
public int getItemCount() {
    return data.size();
}

public class ResultViewHolder extends RecyclerView.ViewHolder{

    @BindView(R.id.ErrorBadTextView)
    TextView mBadErrorTextView;

    @BindView(R.id.ErrorBetterTextView)
    TextView mBetterErrorTextView;


    public ResultViewHolder(@NonNull View itemView) {
        super(itemView);

        ButterKnife.bind(this, itemView);
    }

}

private int getViewType(int position){

    Object value = data.get(position);
    if (value instanceof Match){
        return VIEW_TYPE_MATCH;
    }else {
        return VIEW_TYPE_REPLACEMENT;
    }
}

}

分段：

public class Tab1Fragment_GrammarChecker extends Fragment {

private static final String TAG = "Tab1Fragment";

@BindView(R.id.InputTextEditText)
EditText mInputGrammarEditText;

// @BindView(R.id.MatchRecyclerView) // RecyclerView mMatchRecyclerView;

@BindView(R.id.ErrorsRecyclerView)
RecyclerView mErrorsRecyclerView;

List<Match> matches1 = new ArrayList<>();
public ArrayList<Match> matchArrayList = new ArrayList<>();
public ArrayList<Match> matchData = new ArrayList<>();

public ArrayList<Match> matches = new ArrayList<>();
public List<Replacement> replacementsList = new ArrayList<>();

public static String userInput;
public String apiKey = "";
public String language = "en-US";

@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.tab1_grammar_checker, container, false);

    ButterKnife.bind(this, view);

    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getContext());
    mErrorsRecyclerView.setLayoutManager(layoutManager);
    mErrorsRecyclerView.setItemAnimator(new DefaultItemAnimator());

    return view;
}

@OnClick(R.id.checkGrammarButton)
public void setOnClick(View view){
    userInput = mInputGrammarEditText.getText().toString().trim();
    if(TextUtils.isEmpty(userInput)){
        matches.clear();
        Snackbar snackbar = Snackbar
                .make(view, R.string.fieldEmptyMessage, Snackbar.LENGTH_LONG);

        snackbar.show();
        return;
    }
    if (userInput.length() >= 51){
        matches.clear();
        Snackbar snackbar = Snackbar
                .make(view, R.string.fieldEmptyMessage, Snackbar.LENGTH_LONG);

        snackbar.show();
        return;
    }
    loadJson();
}

public void loadJson(){
    Retrofit.Builder builder = new Retrofit.Builder()
            .baseUrl("http://api.grammarbot.io")
            .addConverterFactory(GsonConverterFactory.create());

    Retrofit retrofit = builder.build();
    Service serviceAPI = retrofit.create(Service.class);
    Call<GrammarBotMain> loadErrorsCall = serviceAPI.readErrorsGrammar(apiKey, userInput, language);

    final ProgressDialog progressDialog;
    progressDialog = new ProgressDialog(getActivity());
    progressDialog.setMax(100);
    progressDialog.setMessage(getResources().getString(R.string.progressDialogLoadingResultMessage));
    progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    progressDialog.show();

    loadErrorsCall.enqueue(new Callback<GrammarBotMain>() {
        @Override
        public void onResponse(Call<GrammarBotMain> call, Response<GrammarBotMain> response) {
            progressDialog.dismiss();
            GrammarBotMain grammarBotMain = response.body();

            matches.clear();
            matches = grammarBotMain.getMatches();

            if (matches.size() == 0){

                final InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
                Snackbar snackbar = Snackbar
                        .make(getView(), R.string.noError, Snackbar.LENGTH_LONG);

                snackbar.show();
                return;
            }
            final InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);

            mErrorsRecyclerView.setAdapter(new ResultAdapter(getContext(), matches));
            Log.i("Fragment", "SUCCESS " + matches.size());
        }

        @Override
        public void onFailure(Call<GrammarBotMain> call, Throwable t) {
            progressDialog.dismiss();
            Log.e("Error: ", t.getMessage());
        }
    });
}
}

我想要的输出：

Cardview1：（第一个错误）消息建议：s1，s2，s3，s4

Cardview2：（对于另一个错误）消息建议：s1，s2，s3，s4

... 等等

这就是我现在的输出：
