Question

我正在制作一个应用程序，其中我从URL接收一些JSON数据，如所示 Image所示。基本上每个日期数组中都有5个对象，我正在使用此代码段从每个日期数组中获取会话并将会话转换为值。

 JSONObject jsonObject = new JSONObject(response);
 JSONObject dataObj = jsonObject.getJSONObject("data");
      Iterator<String> iter = dataObj.keys();
      while (iter.hasNext()) {
              key = iter.next();
              JSONArray datesArray = dataObj.getJSONArray(key);
              sessionsfrom = new ArrayList<String>();

              JSONObject datesObjectt = datesArray.getJSONObject(4);

              for (int i = 0; i < datesArray.length(); i++) {
                  JSONObject datesObject = datesArray.getJSONObject(i);
                  sessionsfrom.add(datesObject.getString("session_from") + " - " +datesObject.getString("session_to") );
                  mBaseRecyclerAdapter.setItems(sessionsfrom);
                                    }

在最后一行中，我将所有会话和从会话到值的所有存储在arraylist中，并放入回收器视图的适配器中。这些会话正在此应用中创建时隙，如Image所示现在，我想要的是我必须将 bookingFound值从json保存到会话和会话到值之间的某个位置，即它不显示在应用程序中，但在每个广告位的背景中，bookingFoung的每个值都必须是存储，以便在填充 viewholder 时，我可以检查哪些bookingFound插槽返回true，哪些返回false，以便在bookingFoundtrue时将插槽的颜色更改为灰色

要填充视图持有人，我需要以下代码

   private BaseRecyclerAdapter<String, CourtDetailsTimeViewHolder> mBaseRecyclerAdapter = new BaseRecyclerAdapter<String, CourtDetailsTimeViewHolder>(CourtDetailsTimeViewHolder.class, R.layout.item_court_details_availability_time) {

    @Override
    protected void populateViewHolder(CourtDetailsTimeViewHolder viewHolder, String model, int position) {
       // SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getContext());
        //String name = preferences.getString("slotfound", "");
        viewHolder.mCheckBox.setOnCheckedChangeListener(null);
        viewHolder.mCheckBox.setText(model);
        viewHolder.mCheckBox.setChecked(getChecked(model));
        /*for (int i = 0; i < bookingcheck.size(); i++) {
            if (bookingcheck.get(i).contains("true")) {
                viewHolder.mCheckBox.setEnabled(false);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details_disable);
            } else {
                viewHolder.mCheckBox.setEnabled(true);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details);
            }
        }*/

    }
};

在此代码中，注释的部分是我尝试过的部分，但没有用。我将bookingFound值放在bookingcheck数组列表中，然后检查它是否包含true，然后禁用插槽，否则启用了它，但是它不起作用...请帮助

结论

1-存储bookingFound json值，就像会话和值之间的会话

2-使用该值在应用程序上启用或禁用插槽

快速修复

使用

datesObject.getString("session_from") + " - " +datesObject.getString("session_to")+"$"+datesObject.get("bookingFound").getAsBoolean()

显示会话使用时

String Session = "02:00 AM - 02:30 AM$true";
String[] separated = currentString.split("$");
separated[0]; // this will contain "02:00 AM - 02:30 AM"
separated[1]; // this will contain "true"

for (int i = 0; i < bookingcheck.size(); i++) {
            if (bookingcheck.get(i).contains("true")) {
                viewHolder.mCheckBox.setEnabled(false);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details_disable);
            } else {
                viewHolder.mCheckBox.setEnabled(true);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details);
            }
        }

您必须更改一些代码。首先，为会话创建一个自定义对象，以提高性能和代码设计

public class SessionModel {

    String sessionFrom;
    String sessionTo;
    boolean sessionFound;


    public SessionModel(String sessionFrom, String sessionTo, boolean sessionFound) {
        this.sessionFrom = sessionFrom;
        this.sessionTo = sessionTo;
        this.sessionFound = sessionFound;
    }


    public String getSessionFrom() {
        return sessionFrom;
    }

    public void setSessionFrom(String sessionFrom) {
        this.sessionFrom = sessionFrom;
    }

    public String getSessionTo() {
        return sessionTo;
    }

    public void setSessionTo(String sessionTo) {
        this.sessionTo = sessionTo;
    }

    public boolean isSessionFound() {
        return sessionFound;
    }

    public void setSessionFound(boolean sessionFound) {
        this.sessionFound = sessionFound;
    }
}

然后创建此对象的数组列表，并在适配器中“在完成循环之后”使用此数组列表

JSONObject jsonObject = new JSONObject(response);
    JSONObject dataObj = jsonObject.getJSONObject("data");
    Iterator<String> iter = dataObj.keys();
    while (iter.hasNext()) {
    key = iter.next();
    JSONArray datesArray = dataObj.getJSONArray(key);
    sessionsfrom = new ArrayList<SessionModel>();

    JSONObject datesObjectt = datesArray.getJSONObject(4);

    for (int i = 0; i < datesArray.length(); i++) {
    JSONObject datesObject = datesArray.getJSONObject(i);
    sessionsfrom.add(SessionModel(datesObject.getString("session_from"), datesObject.getString("session_to"), datesObject.getboolean("bookinFound")));
    }
    mBaseRecyclerAdapter.setItems(sessionsfrom);

在您的适配器中

private BaseRecyclerAdapter<String, CourtDetailsTimeViewHolder> mBaseRecyclerAdapter = new BaseRecyclerAdapter<String, CourtDetailsTimeViewHolder>(CourtDetailsTimeViewHolder.class, R.layout.item_court_details_availability_time) {

    @Override
    protected void populateViewHolder(CourtDetailsTimeViewHolder viewHolder, SessionModel model, int position) {

        viewHolder.mCheckBox.setOnCheckedChangeListener(null);
        viewHolder.mCheckBox.setText(model.getgetSessionFrom+"-"+model.getSessionTo);
        viewHolder.mCheckBox.setChecked(getChecked(model));

            if (model.get(i).isSessionFound()) {
                viewHolder.mCheckBox.setEnabled(false);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details_disable);
            } else {
                viewHolder.mCheckBox.setEnabled(true);
                viewHolder.mCheckBox.setBackgroundResource(R.drawable.slctr_bg_cb_challenges_details);
            }


    }
};

将值从json数据存储到arraylist并填充视图持有者
