Question

我需要更改DatePicker的字体颜色，它被视为日历。我发现的所有回复都适合微调器视图。那么有没有办法在日历视图中更改字体颜色？

Answer 1

您可以使用getDeclaredFields（）方法

执行此操作

示例：我在这里更改了文本大小和填充，这对我有用。

DatePicker datepicker = (DatePicker) findViewById(R.id.datePicker);

    try {
        Field f[] = datepicker.getClass().getDeclaredFields();
        for (Field field : f) 
        {
            if (field.getName().equals("mYearPicker")) 
            {
                field.setAccessible(true);
                Object yearPicker = new Object();
                yearPicker = field.get(datepicker);
                ((View) yearPicker).setVisibility(View.VISIBLE);
                ((View) yearPicker).setPadding(-2, 0, -2, 0);

                View childpicker;
                childpicker = (View) findViewById(Resources.getSystem().getIdentifier("year", "id","android"));
                EditText textview = (EditText) childpicker.findViewById(Resources.getSystem().getIdentifier("timepicker_input", "id", "android"));
                textview.setTextSize(26);
                textview.setPadding(-3, 0, -3, 0);

                //System.out.println("ss1:"+field);
            }

            if (field.getName().equals("mDayPicker")) 
            {
                field.setAccessible(true);
                Object yearPicker = new Object();
                yearPicker = field.get(datepicker);
                ((View) yearPicker).setVisibility(View.VISIBLE);
                ((View) yearPicker).setPadding(-2, 0, -2, 0);


                View childpicker;
                childpicker = (View) findViewById(Resources.getSystem().getIdentifier("month", "id","android"));
                EditText textview = (EditText) childpicker.findViewById(Resources.getSystem().getIdentifier("timepicker_input", "id", "android"));
                textview.setTextSize(26);
                textview.setPadding(-3, 0, -3, 0);

                //System.out.println("ss2:"+field);
            }

            if (field.getName().equals("mMonthPicker")) 
            {
                field.setAccessible(true);
                Object yearPicker = new Object();
                yearPicker = field.get(datepicker);
                ((View) yearPicker).setVisibility(View.VISIBLE);
                ((View) yearPicker).setPadding(-2, 0, -2, 0);

                View childpicker;
                childpicker = (View) findViewById(Resources.getSystem().getIdentifier("day", "id","android"));
                EditText textview = (EditText) childpicker.findViewById(Resources.getSystem().getIdentifier("timepicker_input", "id", "android"));
                textview.setTextSize(26);
                textview.setPadding(-3, 0, -3, 0);
                //System.out.println("ss3:"+field);
            }
            //System.out.println("ss:"+field);


        }
    } catch (SecurityException e) {
        Log.d("ERROR", e.getMessage());
    } catch (IllegalArgumentException e) {
        Log.d("ERROR", e.getMessage());
    } catch (IllegalAccessException e) {
        Log.d("ERROR", e.getMessage());
    }catch (Exception e) {
        Log.d("ERROR", e.getMessage());
    }
