Change Datepicker dialog color for Android 5.0

问题:

Is it possible to change the datepicker (and also the timepicker) colour scheme for android 5.0?

I\'ve tryed setting the accent colours, but this doesn\'t work (both with and without android:):

<!-- colorPrimary is used for the default action bar background -->
<item name=\"colorPrimary\">@color/purple</item>

<!-- colorPrimaryDark is used for the status bar -->
<item name=\"colorPrimaryDark\">@color/purple_tint</item>

<!-- colorAccent is used as the default value for colorControlActivated
     which is used to tint widgets -->
<item name=\"colorAccent\">@color/purple_tint</item>

From original:

To something like this:

The reason why Neil\'s suggestion results in a fullscreen DatePicker is the choice of parent theme:

<!-- Theme.AppCompat.Light is not a dialog theme -->
<style name=\"DialogTheme\" parent=\"**Theme.AppCompat.Light**\">
    <item name=\"colorAccent\">@color/blue_500</item>
</style>

Moreover, if you go this route, you have to specify the theme while creating the DatePickerDialog:

// R.style.DialogTheme
new DatePickerDialog(MainActivity.this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        //DO SOMETHING
    }
}, 2015, 02, 26).show();

This, in my opinion, is not good. One should try to keep the styling out of java and inside styles.xml/themes.xml.

I do agree that Neil\'s suggestion, with a bit of change (changing the parent theme to say, Theme.Material.Light.Dialog) will get you the desired result. But, here\'s the other way:

On first inspection, we come across datePickerStyle which defines things such as: headerBackground(what you are trying to change), dayOfWeekBackground, and a few other text-colors and text-styles.

Overriding this attribute in your app\'s theme will not work. DatePickerDialog uses a separate theme assignable by the attribute datePickerDialogTheme. So, for our changes to take affect, we must override datePickerStyle inside an overriden datePickerDialogTheme.

Here we go:

Override datePickerDialogTheme inside your app\'s base theme:

<style name=\"AppBaseTheme\" parent=\"android:Theme.Material.Light\">
    ....
    <item name=\"android:datePickerDialogTheme\">@style/MyDatePickerDialogTheme</item>
</style>

Define MyDatePickerDialogTheme. The choice of parent theme will depend on what your app\'s base theme is: it could be either Theme.Material.Dialog or Theme.Material.Light.Dialog:

<style name=\"MyDatePickerDialogTheme\" parent=\"android:Theme.Material.Light.Dialog\">
    <item name=\"android:datePickerStyle\">@style/MyDatePickerStyle</item>
</style>

We have overridden datePickerStyle with the style MyDatePickerStyle. The choice of parent will once again depend on what your app\'s base theme is: either Widget.Material.DatePicker or Widget.Material.Light.DatePicker. Define it as per your requirements:

<style name=\"MyDatePickerStyle\" parent=\"@android:style/Widget.Material.Light.DatePicker\">
    <item name=\"android:headerBackground\">@color/chosen_header_bg_color</item>
</style>

Currently, we are only overriding headerBackground which by default is set to ?attr/colorAccent (this is also why Neil suggestion works in changing the background). But there\'s quite a lot of customization possible:

dayOfWeekBackground
dayOfWeekTextAppearance
headerMonthTextAppearance
headerDayOfMonthTextAppearance
headerYearTextAppearance
headerSelectedTextColor
yearListItemTextAppearance
yearListSelectorColor
calendarTextColor
calendarSelectedTextColor

If you don\'t want this much control (customization), you don\'t need to override datePickerStyle. colorAccent controls most of the DatePicker\'s colors. So, overriding just colorAccent inside MyDatePickerDialogTheme should work:

<style name=\"MyDatePickerDialogTheme\" parent=\"android:Theme.Material.Light.Dialog\">
    <item name=\"android:colorAccent\">@color/date_picker_accent</item>

    <!-- No need to override \'datePickerStyle\' -->
    <!-- <item name=\"android:datePickerStyle\">@style/MyDatePickerStyle</item> -->
</style>

Overriding colorAccent gives you the added benefit of changing OK & CANCEL text colors as well. Not bad.

This way you don\'t have to provide any styling information to DatePickerDialog\'s constructor. Everything has been wired properly:

DatePickerDialog dpd = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

    }
 }, 2015, 5, 22);

 dpd.show();

Give this a try.

The code

new DatePickerDialog(MainActivity.this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        //DO SOMETHING
    }
}, 2015, 02, 26).show();

The Style In your styles.xml file

EDIT - Changed theme to Theme.AppCompat.Light.Dialog as suggested

<style name=\"DialogTheme\" parent=\"Theme.AppCompat.Light.Dialog\">
    <item name=\"colorAccent\">@color/blue_500</item>
</style>

try this, work for me

Put the two options, colorAccent and android:colorAccent

<style name=\"AppTheme\" parent=\"@style/Theme.AppCompat.Light.NoActionBar\">
    <!-- Customize your theme here. -->
   ....
    <item name=\"android:dialogTheme\">@style/AppTheme.DialogTheme</item>
    <item name=\"android:datePickerDialogTheme\">@style/Dialog.Theme</item>
</style>

<style name=\"AppTheme.DialogTheme\" parent=\"Theme.AppCompat.Light.Dialog\">

<!-- Put the two options, colorAccent and android:colorAccent. -->
    <item name=\"colorAccent\">@color/colorPrimary</item>
    <item name=\"android:colorPrimary\">@color/colorPrimary</item>
    <item name=\"android:colorPrimaryDark\">@color/colorPrimaryDark</item>
    <item name=\"android:colorAccent\">@color/colorPrimary</item>
 </style>

Just to mention, you can also use the default a theme like android.R.style.Theme_DeviceDefault_Light_Dialog instead.

new DatePickerDialog(MainActivity.this, android.R.style.Theme_DeviceDefault_Light_Dialog, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    //DO SOMETHING
    }
}, 2015, 02, 26).show();

I had the problem that time picker buttons have not been seen in the screen for API 24 in android. (API 21+) it is solved by

<style name=\"MyDatePickerDialogTheme\" parent=\"android:Theme.Material.Light.Dialog\">
            <item name=\"android:colorAccent\">@color/colorPrimary2</item></style>

<style name=\"Theme\" parent=\"BBaseTheme\">
         <item name=\"android:datePickerDialogTheme\">@style/MyDatePickerDialogTheme</item>
</style>

回答7:

<style name=\"AppThemeDatePicker\" parent=\"Theme.AppCompat.Light.NoActionBar\">
    <item name=\"colorAccent\">@color/select2</item>
    <item name=\"android:colorAccent\">@color/select2</item>
    <item name=\"android:datePickerStyle\">@style/MyDatePickerStyle</item>
</style>


<style name=\"MyDatePickerStyle\" parent=\"@android:style/Widget.Material.Light.DatePicker\">
    <item name=\"android:headerBackground\">@color/select2</item>
</style>

For Changing Year list item text color (SPECIFIC FOR ANDROID 5.0)

Just set certain text color in your date picker dialog style. For some reason setting flag yearListItemTextAppearance doesn\'t reflect any change on year list.

<item name=\"android:textColor\">@android:color/black</item>

Create a new style

<!-- Theme.AppCompat.Light.Dialog -->
<style name=\"DialogTheme\" parent=\"Theme.AppCompat.Light.Dialog\">
    <item name=\"colorAccent\">@color/blue_500</item>
</style>

Java code:

The parent theme is the key here. Choose your colorAccent

DatePickerDialog = new DatePickerDialog(context,R.style.DialogTheme,this,now.get(Calendar.YEAR),now.get(Calendar.MONTH),now.get(Calendar.DAY_OF_MONTH);

Result:
