Question

在我的应用程序中，我使用DatePicker对话框和时间选择器对话框来相应地选择日期和时间。现在，在那些对话框中，颜色是根据我的Themecolor设置的。但我想做的是手动改变这些颜色。为了exmaple我已经改变了工具栏颜色，就这样工具栏.setBackgroundColor（Constant.color）;但是，如何手动以相同的方式更改标题颜色（当前日期显示 - 我已附加图片）和日期选择器颜色（指示当前日期的圆形选择器）。

这是我的DeatepickerDialog

    appColor = app_preferences.getInt("color", 0xff3F51B5);
    appTheme = app_preferences.getInt("theme", 0xff3F51B5);
    themeColor = appColor;
    constant.color = appColor;

    if (themeColor == 0){
        setTheme(Constant.theme);

Answer 1

new DatePickerDialog(MainActivity.this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    //Your Code
}
}, year, monthOfYear, dayOfMonth).show();

编辑 - 按照建议将主题更改为Theme.AppCompat.Light.Dialog

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

Answer 2

尝试这样做：

在styles.xml中添加以下内容：

DatePickerDialog mDatePickerDialog = new DatePickerDialog(mContext, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener()

然后在你的datePicker中改为做。
