我正在尝试在另一个活动之上显示DatePicker
对话框,发生的事情是它以某种方式继承了它的颜色。
我希望它有绿色标题和白色背景,
以下是样式
的摘录<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>
此代码用于弹出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了白色背景,
<item name="android:background">@color/app_background</item>
我尝试过的最后一件事是使用AlertDialog.THEME_DEVICE_DEFAULT_DARK
作为DatePicker
主题
DatePickerDialog datepicker = new DatePickerDialog(this,
AlertDialog.THEME_DEVICE_DEFAULT_DARK, new
DatePickerDialog.OnDateSetListener()
以下是我从
打开对话框的活动样式<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?我很感激任何指导。我试图关注this answer, but had no luck

此代码适合我试试这个......
styles.xml
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">@android:color/holo_green_dark</item>
</style>
弹出代码
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();

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>

以下自定义DatePickerDoalog类不仅可以自定义暗色,而且还可以使暗淡的动画显示
/**

public class DatePickerDialogCustomDim extends DatePickerDialog {
private final long animDuration = 100;
private float dimAmount = 0.7f;
private Drawable dimDrawable;
private ViewGroup root;
private OnDismissListener outsideDismissListener;
private final OnDismissListener dismissListener = new OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialog) {
final ObjectAnimator animator = ObjectAnimator.ofPropertyValuesHolder(dimDrawable,
PropertyValuesHolder.ofInt("alpha", (int) (255 * dimAmount), 0));
animator.setTarget(dimDrawable);
animator.setDuration(animDuration);
animator.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
ViewGroupOverlay overlay = root.getOverlay();
overlay.remove(dimDrawable);
}
});
animator.start();
if (outsideDismissListener != null)
outsideDismissListener.onDismiss(dialog);
}
};
@TargetApi(Build.VERSION_CODES.N)
public DatePickerDialogCustomDim(@NonNull Context context) {
this(context, 0);
}
@TargetApi(Build.VERSION_CODES.N)
public DatePickerDialogCustomDim(@NonNull Context context, @StyleRes int themeResId) {
this(context, themeResId, null, -1, -1, -1);
init(context);
}
public DatePickerDialogCustomDim(@NonNull Context context,
@Nullable OnDateSetListener listener,
int year,
int month,
int dayOfMonth) {
this(context, 0, listener, year, month, dayOfMonth);
}
public DatePickerDialogCustomDim(@NonNull Context context,
@StyleRes int themeResId,
@Nullable OnDateSetListener listener,
int year,
int monthOfYear,
int dayOfMonth) {
super(context, themeResId, listener, year, monthOfYear, dayOfMonth);
init(context);
}
private void init(Context context) {
root = ((Activity) context).getWindow().getDecorView().findViewById(android.R.id.content);
super.setOnDismissListener(dismissListener);
}
public void setDimAmount(@FloatRange(from = 0, to = 1f) float dim) {
dimAmount = dim;
}
@Override
public void show() {
super.show();
dimDrawable = new ColorDrawable(Color.WHITE); // a dim color
dimDrawable.setBounds(0, 0, root.getWidth(), root.getHeight());
ViewGroupOverlay overlay = root.getOverlay();
overlay.add(dimDrawable);
ObjectAnimator animator = ObjectAnimator.ofPropertyValuesHolder(dimDrawable,
PropertyValuesHolder.ofInt("alpha", 0, (int) (255 * dimAmount)));
animator.setTarget(dimDrawable);
animator.setDuration(animDuration);
animator.start();
}
@Override
public void setOnDismissListener(@Nullable OnDismissListener listener) {
outsideDismissListener = listener;
}
}
它与一种样式结合使用(主要是禁用暗淡)
<style name="DatePickerDialogTheme" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">@color/accent</item>
<item name="android:textColorLink">@color/primary</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
