android 解決datepicker和timepicker一起用引起的配置樣式問題，androidpicker

最近需要用到datepicke和timepicker一起用，但是發現個問題，通過XML布局檔案無法跳轉大小樣式，XML檔案內容如下

<?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>

螢幕大的手機能顯示全，但是小的就這樣了，最後經過查閱資料解決了這個問題，解決方案如下：

/** * 調整FrameLayout大小 * @param tp */private void resizePikcer(FrameLayout tp){List<NumberPicker> npList = findNumberPicker(tp);for(NumberPicker np:npList){resizeNumberPicker(np);}}/** * 得到viewGroup裡面的numberpicker組件 * @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;}/* * 調整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);                                                                            }

然後這樣調用就行了：

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

看下調整後的吧：

是不是很簡單呢，文字也可以改變，通過style,例子如下：
