更改DatePicker背景颜色

Question

我试图DatePicker在另一个活动的顶部显示一个对话框，正在发生的是它以某种方式继承了它的颜色。

我希望它具有绿色的标头和白色的背景，

这是样式的节选

<style name="DatePickerDialog" parent="@android:style/Theme.Holo.Light">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="colorAccent">@color/primary</item>
</style>

这段代码用来弹出 DatePicker

    DatePickerDialog datepicker = new DatePickerDialog(this, R.style.DatePickerDialog, new DatePickerDialog.OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            TextView newdate = (TextView) findViewById(R.id.newdate);
            Date date = getDate(year, monthOfYear, dayOfMonth);
            DateFormat dateformat = new SimpleDateFormat(getResources().getString(R.string.date_format_full));
            newdate.setText(dateformat.format(date));
        }
    }, newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));

    datepicker.show();

如果我在样式中指定白色背景，

    <item name="android:background">@color/app_background</item>

我尝试过的最后一件事是AlertDialog.THEME_DEVICE_DEFAULT_DARK用作DatePicker主题

DatePickerDialog datepicker = new DatePickerDialog(this, 
AlertDialog.THEME_DEVICE_DEFAULT_DARK, new 
DatePickerDialog.OnDateSetListener() 

这是我从中打开对话框的活动的样式

<style name="UserDialog" parent="android:style/Theme.Dialog">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:background">@color/primary</item>
    <item name="android:textColor">@color/dialog_text</item>
    <item name="colorPrimary">@color/app_background</item>
    <item name="android:windowTitleStyle">@style/NewDialogTitle</item>
</style>

<style name="NewDialogTitle" parent="@android:style/TextAppearance.DialogWindowTitle">
    <item name="android:gravity">center_horizontal</item>
</style>

我正在使用的颜色

<color name="primary">#4CAF50</color>
<color name="app_background">#FFFFFF</color>

有谁知道如何完成它？我将不胜感激。我尝试遵循此答案，但没有运气

此代码对我有用，请尝试...

styles.xml

<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
    <item name="colorAccent">@android:color/holo_green_dark</item>
</style>

弹出码

        Calendar mcurrentDate = Calendar.getInstance();
        int mYear = mcurrentDate.get(Calendar.YEAR);
        int mMonth = mcurrentDate.get(Calendar.MONTH);
        int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

        DatePickerDialog mDatePicker;
        mDatePicker = new DatePickerDialog(context, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() {
            public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) {

                Toast.makeText(context,"Selected Date " + + selectedday + "-" + ++selectedmonth  + "-" + selectedyear ,Toast.LENGTH_SHORT).show();
            }
        }, mYear, mMonth, mDay);
        mDatePicker.show();

Answer 2

要在应用程序级别更改 DatePicker 颜色（日历模式），请定义以下属性。

<style name="MyAppTheme" parent="Theme.AppCompat.Light">
    <item name="colorAccent">#ff6d00</item>
    <item name="colorControlActivated">#33691e</item>
    <item name="android:selectableItemBackgroundBorderless">@color/colorPrimaryDark</item>
    <item name="colorControlHighlight">#d50000</item>
</style>
