活动内的全屏DatePicker

我尝试在我使用startActivityForResult调用的活动中显示datePicker和timePicker小部件。两个选择器都应与父布局宽度匹配。在我的情况下,它适用于timePicker,但datePicker不会填满整个屏幕。

我尝试以编程方式测量显示大小,并在onResume中设置datePicker的layoutparams。但不幸的是,它没有用。

如何实现datePicker小部件,使其延伸到父布局的宽度?

activity_date_time_picker.xml:

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

    <include
        android:id="@+id/toolbar"
        layout="@layout/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <ScrollView
        android:id="@+id/scroll_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/toolbar">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <DatePicker
                android:id="@+id/datePicker"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="center" />

            <TimePicker
                android:id="@+id/timePicker"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="center" />

        </LinearLayout>
    </ScrollView>
</RelativeLayout>

DateTimePickerActivity中的onResume方法:

/* ... */
@Override
protected void onResume() {
    super.onResume();

    int width = Resources.getSystem().getDisplayMetrics().widthPixels;
    LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) datePicker.getLayoutParams();
    params.width = width;
    datePicker.setLayoutParams(params);
}
/* ... */

试一下

<强> Style.xml

<style name="DialogTheme" parent="Theme.AppCompat.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

MainActivity.java 将主题应用于日期选择器的构造函数(R.style.AppTheme)

 DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(), R.style.AppTheme, this, year, month, day);
            datePickerDialog.getDatePicker().setMaxDate(c.getTimeInMillis());
            return datePickerDialog;
