系統自帶的DatePickerDialog隻能一次性選擇一個日期,有時候我們需要這樣的功能:需要錄入2個日期,比如開始日期和結束日期,如果采用DatePickerDialog需要彈出2次Dialog,能不能一次就搞定呢?那就需要下面的内容了。
自定義一個DatePickerDialog,實作OnDateChangedListener接口,裡面有2個DatePicker,然後分别對這2個DatePicker設定日期就行了。
package qianlong.qlmobile.view;

super.onCreate(savedInstanceState);
setContentView(R.layout.ipo_dialog_date_picker);

if(onDateSetListener!=null){

}
dismiss();
break;

}

public interface OnDateSetListener {

}
public void setOnDateSetListener(OnDateSetListener onDateSetListener){

}
@Override

if(view==startDatePicker){
this.start_year=year;

}else if(view==endDatePicker){
this.end_year=year;
this.end_monthOfYear=monthOfYear;

}
// updateDate(view,year,monthOfYear,dayOfMonth);
}
// public void updateDate(
// DatePicker view, int year, int monthOfYear,int dayOfMonth){
// view.updateDate(year, monthOfYear, dayOfMonth);
// }
}
我隻是簡單的實作了一下,更多的擴充請大家添上。
ipo_dialog_date_picker.xml如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:layout_width="fill_parent"
android:layout_height="fill_parent"

<DatePicker
android:id="@+id/startDatePicker"
android:padding="5dip"
android:layout_gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</LinearLayout>
<LinearLayout

android:layout_height="wrap_content"
android:text="結束時間:"

<DatePicker
android:id="@+id/endDatePicker"

</LinearLayout>
</LinearLayout>
<LinearLayout

<Button android:id="@+id/apply"
android:layout_width="100dip"
android:layout_height="wrap_content"
android:text="确認"
android:textSize="@dimen/font_middler"

<Button android:id="@+id/cancel"

android:layout_height="wrap_content"
android:text="取消"

</LinearLayout>
用法:
private Calendar calendar_start = Calendar.getInstance();
private Calendar calendar_end = Calendar.getInstance();
//在需要的地方填入如下代碼(通常是在Button的click事件中.)
qianlong.qlmobile.view.DatePickerDialog d=new qianlong.qlmobile.view.DatePickerDialog(
HK_TradeIPOActivity.this.getParent(),
calendar_start.get(Calendar.YEAR),
calendar_start.get(Calendar.MONTH),
calendar_start.get(Calendar.DAY_OF_MONTH),
calendar_end.get(Calendar.YEAR),
calendar_end.get(Calendar.MONTH),
calendar_end.get(Calendar.DAY_OF_MONTH)
);
d.setOnDateSetListener(onDateSetListener);
d.show();
//自己實作需要的功能
private qianlong.qlmobile.view.DatePickerDialog.OnDateSetListener onDateSetListener=new qianlong.qlmobile.view.DatePickerDialog.OnDateSetListener(){
@Override
public void onDateSet(int start_year,
int start_monthOfYear,
int start_dayOfMonth,
int end_year,
int end_monthOfYear,
int end_dayOfMonth) {
// TODO Auto-generated method stub
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");
calendar_start.set(Calendar.YEAR, start_year);
calendar_start.set(Calendar.MONTH, start_monthOfYear);
calendar_start.set(Calendar.DAY_OF_MONTH, start_dayOfMonth);
calendar_end.set(Calendar.YEAR, end_year);
calendar_end.set(Calendar.MONTH, end_monthOfYear);
calendar_end.set(Calendar.DAY_OF_MONTH, end_dayOfMonth);
String startDate=simpleDateFormat.format(calendar_start.getTime());
String endDate=simpleDateFormat.format(calendar_end.getTime());
//doSomething(startDate,endDate)
}
};
over.
