android 解决datepicker和timepicker一起用引起的布局样式问题
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); }
然后这样调用就行了:
final DatePicker datePicker = (DatePicker) view.findViewById(R.id.date_picker); final TimePicker timePicker = (TimePicker) view.findViewById(R.id.time_picker); resizePikcer(datePicker);//调整datepicker大小 resizePikcer(timePicker);//调整timepicker大小
看下调整后的效果图吧:
