Android：某些设备上的DatePicker微调器文本颜色为白色

Question

I realized that on some devices my DatePicker 's spinners don't show because the text is white instead of black (as it should be).

Example with a Honor 5C:

Example with a One Plus 5:

I realized it by setting a black background color instead:

I tried to change a lot of different attributes but nothing worked.

Here is the underlying code:

final AlertDialog.Builder datePickerDialog = new AlertDialog.Builder(getContext(), R.style.AlertDialog);
final View view = fragment.getActivity().getLayoutInflater().inflate(R.layout.views_form_pick_date_dialog_day, null);
final AppCompatTextView datePickerDialogTitle = (AppCompatTextView) view.findViewById(R.id.views_form_pick_date_dialog_title);
final DatePicker datePickerDialogSpinner = (DatePicker) view.findViewById(R.id.views_form_pick_date_dialog_spinner);
datePickerDialogSpinner.updateDate(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
datePickerDialog.setView(view);
datePickerDialog.show();

The XML layout associated:

R.layout.views_form_pick_date_dialog_day

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.AppCompatTextView style="@style/TextViewBody"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="@dimen/style_size_space_medium"
        android:background="@color/style_color_red"
        android:text="@string/app_name"
        android:id="@+id/views_form_pick_date_dialog_title" />

    <DatePicker
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/views_form_pick_date_dialog_title"
        android:calendarViewShown="false"
        android:datePickerMode="spinner"
        android:id="@+id/views_form_pick_date_dialog_spinner" />

</RelativeLayout>

Thanks for your help.

Try this,

Use this as your Activity style.

<style parent="Theme.AppCompat.Light.NoActionBar" name="MyActivityTheme">

<!-- Customize your theme here. -->

<item name="colorPrimary">@color/colorPrimary</item>

<item name="colorPrimaryDark">@color/colorPrimaryDark</item>

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

<item name="colorAccent">@color/colorAccent</item>

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


</style>

and in your manifest add its as your Activity theme.

<activity
        android:name="yourActivity"
        android:theme="@style/MyActivityTheme"/>

Change the datePicker textColor by simply doing this:

 <DatePicker
        android:id="@+id/start_date_text"
        android:layout_width="400dp"
        android:layout_height="190dp"
        android:datePickerMode="spinner"
        android:calendarViewShown="false"
        style="@style/MyDatePicker" />

and style

<style name="MyDatePicker" parent="android:Widget.Material.Light.DatePicker">
     <item name="android:textColorPrimary">@color/Black</item>
</style>

Answer 3

Set style for your date picker

<style name="datepicker" parent="Theme.AppCompat.Light.Dialog">
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primary_dark</item>
        <item name="colorAccent">@color/primary</item>
</style>
