如何在android的Timepicker对话框中更改分隔线颜色

<style name="TimePickerDialogTheme" parent="Theme.AppCompat.Light.Dialog">
    <!-- 自定义对话框背景颜色 -->
    <item name="android:windowBackground">@android:color/white</item>
</style>

TimePickerDialog timePickerDialog = new TimePickerDialog(context, R.style.TimePickerDialogTheme, null, hour, minute, false);

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <size android:width="1dp" />
    <!-- 自定义分隔线颜色 -->
    <solid android:color="#FF0000" />
</shape>

TimePicker timePicker = timePickerDialog.getTimePicker();
try {
    // 获取TimePicker内部的mDelegate成员变量
    Field mDelegateField = timePicker.getClass().getDeclaredField("mDelegate");
    mDelegateField.setAccessible(true);
    Object mDelegate = mDelegateField.get(timePicker);

    // 获取mDelegate内部的mPicker成员变量
    Field mPickerField = mDelegate.getClass().getDeclaredField("mPicker");
    mPickerField.setAccessible(true);
    Object mPicker = mPickerField.get(mDelegate);

    // 获取mPicker内部的mDivider成员变量
    Field mDividerField = mPicker.getClass().getDeclaredField("mDivider");
    mDividerField.setAccessible(true);

    // 使用自定义的分隔线
    Drawable customDivider = ContextCompat.getDrawable(context, R.drawable.divider);
    mDividerField.set(mPicker, customDivider);
} catch (Exception e) {
    e.printStackTrace();
}
