关键代码如下：
~~~
private void setTimePickerDividerColor(TimePicker timePicker) {
LinearLayout llFirst = (LinearLayout) timePicker.getChildAt(0);
LinearLayout mSpinners = (LinearLayout) llFirst.getChildAt(1);
for (int i = 0; i < mSpinners.getChildCount(); i++) {
if (mSpinners.getChildAt(i) instanceof NumberPicker) {
Field[] pickerFields = NumberPicker.class.getDeclaredFields();
setPickerMargin((NumberPicker) mSpinners.getChildAt(i));
for (Field pf : pickerFields) {
if (pf.getName().equals("mSelectionDivider")) {
pf.setAccessible(true);
try {
pf.set(mSpinners.getChildAt(i), new ColorDrawable());
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (Resources.NotFoundException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
break;
}
}
}
}
}
~~~
当compileSdkVersion 23之上时，此时默认的timepick是clock类型的
timepickermode 可以设置为spinner
