android 解决datepicker和timepicker一起用引起的布局样式有关问题

最近需要用到datepicke和timepicker一起用，但是发现个问题，通过XML布局文件无法跳转大小样式，XML文件内容如下

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="horizontal" >    <DatePicker        android:id="@+id/date_picker"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_vertical"        android:calendarViewShown="false" />    <TimePicker        android:id="@+id/time_picker"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_vertical" /></LinearLayout>

屏幕大的手机能显示全，但是小的就这样了，最后经过查阅资料解决了这个问题，解决方案如下：

/**	 * 调整FrameLayout大小	 * @param tp	 */	private void resizePikcer(FrameLayout tp){		List<NumberPicker> npList = findNumberPicker(tp);		for(NumberPicker np:npList){			resizeNumberPicker(np);		}	}		/**	 * 得到viewGroup里面的numberpicker组件	 * @param viewGroup	 * @return	 */	private List<NumberPicker> findNumberPicker(ViewGroup viewGroup){		List<NumberPicker> npList = new ArrayList<NumberPicker>();		View child = null;		if(null != viewGroup){			for(int i = 0; i < viewGroup.getChildCount(); i++){				child = viewGroup.getChildAt(i);				if(child instanceof NumberPicker){					npList.add((NumberPicker)child);				}				else if(child instanceof LinearLayout){					List<NumberPicker> result = findNumberPicker((ViewGroup)child);					if(result.size()>0){						return result;					}				}			}		}		return npList;	}		/*	 * 调整numberpicker大小	 */	private void resizeNumberPicker(NumberPicker np){		LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(80, LayoutParams.WRAP_CONTENT);		params.setMargins(10, 0, 10, 0);		np.setLayoutParams(params);                                                                            	}

 final DatePicker datePicker = (DatePicker) view.findViewById(R.id.date_picker);          final TimePicker timePicker = (TimePicker) view.findViewById(R.id.time_picker);        resizePikcer(datePicker);//调整datepicker大小		resizePikcer(timePicker);//调整timepicker大小

看下调整后的效果图吧：
