Question

在下面，我发布了我的json，其中我将获得数天的数组。如果数组包含[5,6,7]，则更改3个文本视图的颜色即。卡片视图中的Th，Fr，Sa。

[

{
    "id":112,
    "patient":"sandeepsingh@innotical.com",
    "salt":"sdfdsf",
    "doctor":"Dr",
    "amount":null,
    "unit":null,
    "method":null,
    "date":"2006-04-02",
    "note":null,
    "frequency":null,
    "reminder":[
    ]
},
{
    "id":114,
    "patient":"sandeepsingh@innotical.com",
    "salt":"Zaleplon",
    "doctor":"ufuffu",
    "amount":"13",
    "unit":1,
    "method":1,
    "date":"2016-06-02",
    "note":"chchjf",
    "frequency":null,
    "reminder":[
        {
            "id":1,
            "time":" ",
            "days":[
                1,
                2,
                3,
                4,
                5,
                6,
                7
            ]
        },
        {
            "id":2,
            "time":" ",
            "days":[
                5,
                6,
                7
            ]
        }
    ]
}

]

并且在这里我发布了我想要更改颜色位置的cardview图像。我想要提前完成一个完整的解决方案。

我的解析代码如下。

 @Override
                public void success(List<SavedMedicationPojo> savedMedicationPojo, Response response) {




                    savedMedicationPojo1.addAll(savedMedicationPojo);
                   // medSetter.setMedicationPojo(savedMedicationPojo1);

                  if (savedMedicationPojo.size()>0){

                    for (int i = 0; i < savedMedicationPojo.size(); i++) {

                       // SavedMedicationPojo medication = new SavedMedicationPojo();


                        mSaltIdList.add(savedMedicationPojo.get(i).getId());
                        mSaltList.add(savedMedicationPojo.get(i).getSalt());

                        mSaltFrequencyList.add(savedMedicationPojo.get(i).getFrequency());
                       // savedMedicationPojo.get(i).getReminder().get(i).
                       int msize = savedMedicationPojo.get(i).getReminder().size();
                        /*if(msize==0)

                            mReminderDaysHashMap.put(i, mDaysList);
                        }*/
                        for (int j = 0;j< savedMedicationPojo.get(i).getReminder().size();j++){
                            mReminderId.add(savedMedicationPojo.get(i).getReminder().get(j).getId());
                            mReminderTime.add(savedMedicationPojo.get(i).getReminder().get(j).getTime());
                                ArrayList<Integer> mDaysList= new ArrayList<Integer>();

                                for (int k = 0; k < savedMedicationPojo.get(i).getReminder().get(j).getDays().size(); k++) {
                                    mDaysList.add(savedMedicationPojo.get(i).getReminder().get(j).getDays().get(k));
                                }
                                mReminderDaysHashMap.put(j, mDaysList);
                           // }

                        }


                    }


                    mDataAdapter.notifyDataSetChanged();
                    pb.setVisibility(View.INVISIBLE);
                  }else{

                      mNoDataView.setVisibility(View.VISIBLE);
                  }

                }

Answer 1

在为卡片设置自定义适配器值时，您可以解析JSON数组值，并使用if else条件语句设置TextViews的所需颜色。

要获取您需要的特定代码，您需要共享解析JSON数据的方式和位置以及卡视图的适配器类的代码。

Answer 2

您可以使用以下代码更改任何textview的背景：

txtView.setBackgroundColor(Color.parseColor("#AA3456"));

如果您想在代码工作后的工作日添加支票：

首先在列表或数组中解析你的日子，
搜索您的日期列表是否包含如下日期编号：

if（Arrays.asList（days）.contains（“1”））{ ... }

重置所有textview的背景颜色并更改特定日期textview的颜色（如果您的列表包含那一天，如下所示：

//重置颜色 txtViewSunday.setBackgroundColor（Color.TRANSPARENT）; txtViewMonday.setBackgroundColor（Color.TRANSPARENT）; txtViewTuesday.setBackgroundColor（Color.TRANSPARENT）; txtViewWednesday.setBackgroundColor（Color.TRANSPARENT）; txtViewThursday.setBackgroundColor（Color.TRANSPARENT）; txtViewFriday.setBackgroundColor（Color.TRANSPARENT）; txtViewSaturday.setBackgroundColor（Color.TRANSPARENT）;

// Update color 
if (Arrays.asList(days).contains("1")){
 txtViewSunday.setBackgroundColor(Color.parseColor("#AA3456"));
}else if (Arrays.asList(days).contains("2")){
 txtViewMonday.setBackgroundColor(Color.parseColor("#AA3456"));
}else if (Arrays.asList(days).contains("3")){
 txtViewTuesday.setBackgroundColor(Color.parseColor("#AA3456"));
}else if (Arrays.asList(days).contains("4")){
 txtViewWednesday.setBackgroundColor(Color.parseColor("#AA3456"));
}else if (Arrays.asList(days).contains("5")){
 txtViewThursday.setBackgroundColor(Color.parseColor("#AA3456"));
}else if (Arrays.asList(days).contains("6")){
 txtViewFriday.setBackgroundColor(Color.parseColor("#AA3456"));
}else if (Arrays.asList(days).contains("7")){
 txtViewSaturday.setBackgroundColor(Color.parseColor("#AA3456"));
}

您必须在适配器中编写此代码。
