我想为我的Datepickers和Timepickers使用自定义皮肤。在XML中更改背景并不起作用（它将背景更改为集合，而不是每个按钮）。 API非常简短，并且没有外观（http://developer.android.com/reference/android/widget/DatePicker.html）。是否可以为Datepickers和Timepickers的按钮使用自定义皮肤？
答案 0 :(得分：12)
好的，你正在为datepicker和时间选择器寻找自定义主题.. 这将允许您更改按钮的主题..

并采用ICS风格
希望这会对你有帮助....答案 1 :(得分：4)
不幸的是，numberpicker是一个内部小部件。 需要覆盖这些背景。而且没有正式的方法可以做到。
<NumberPickerButton android:id="@+id/increment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/timepicker_up_btn" />
<EditText android:id="@+id/timepicker_input"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:singleLine="true"
style="?android:attr/textAppearanceLargeInverse"
android:textColor="@android:color/primary_text_light"
android:textSize="30sp"
android:background="@drawable/timepicker_input" />
<NumberPickerButton android:id="@+id/decrement"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/timepicker_down_btn" />
答案 2 :(得分：3)
这是不安全的，但我相信只有这样才能在没有复制整个班级的情况下为时间戳设定皮肤：
try { for (int i=0; i<2; i++)
{
((ViewGroup) ((ViewGroup) mTimePicker.getChildAt(0)).getChildAt(i)).getChildAt(0).setBackgroundResource(R.drawable.timepicker_up_btn);
((ViewGroup) ((ViewGroup) mTimePicker.getChildAt(0)).getChildAt(i)).getChildAt(1).setBackgroundResource(R.drawable.timepicker_input);
((ViewGroup) ((ViewGroup) mTimePicker.getChildAt(0)).getChildAt(i)).getChildAt(2).setBackgroundResource(R.drawable.timepicker_down_btn);
}
} catch (Throwable t) {/* obviously no the view may look like garbage */}
显然，您必须为您的应用提供引用的drawables
