自定义Dialog:双日期选择器

系统 1508 0
系统自带的DatePickerDialog只能一次性选择一个日期,有时候我们需要这样的功能:需要录入2个日期,比如开始日期和结束日期,如果采用DatePickerDialog需要弹出2次Dialog,能不能一次就搞定呢?那就需要下面的内容了。
自定义一个DatePickerDialog,实现OnDateChangedListener接口,里面有2个DatePicker,然后分别对这2个DatePicker设置日期就行了。

我只是简单的实现了一下,更多的扩展请大家添上。

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"
	    >
	    <LinearLayout
	    android:orientation="vertical"
	    android:layout_width="fill_parent"
	    android:layout_height="fill_parent"
	    android:layout_weight="1"
	    >
	    	<TextView 
	    	android:layout_width="fill_parent"
	   		android:layout_height="wrap_content"
	   		android:text="开始时间:"
	   		android:textSize="@dimen/font_middler"
	   		android:textColor="@color/white"
	   		android:gravity="center"
	    	/>
	    	<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:orientation="vertical"
	    android:layout_width="fill_parent"
	    android:layout_height="fill_parent"
	    android:layout_weight="1"
	    android:layout_marginLeft="5dip"
	    >
	    	<TextView 
	    	android:layout_width="fill_parent"
	   		android:layout_height="wrap_content"
	   		android:text="结束时间:"
	   		android:textSize="@dimen/font_middler"
	   		android:textColor="@color/white"
	   		android:gravity="center"
	    	/>
	    	<DatePicker
		    android:id="@+id/endDatePicker"
		    android:padding="5dip"
		    android:layout_gravity="center_horizontal"
		    android:layout_width="wrap_content"
		    android:layout_height="wrap_content"
		    />
	    </LinearLayout>
	</LinearLayout>
	<LinearLayout
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:layout_marginTop="20dip"
    >
	     <Button android:id="@+id/apply"
	        android:layout_width="100dip"
	   		android:layout_height="wrap_content"
	   		android:text="确认"
	   		android:textSize="@dimen/font_middler"
	   		/>
	     <Button android:id="@+id/cancel"
	        android:layout_width="100dip"
	   		android:layout_height="wrap_content"
	   		android:text="取消"
	   		android:textSize="@dimen/font_middler"
	   		android:layout_marginLeft="20dip"
	   		/>
	</LinearLayout>
</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码(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();



//自己实现需要的功能
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.
