widget(5、DatePicker)

DatePicker 是android下的日期选择器,类似的有TimePicker等。DatePicker 常用定义如下:

    <DatePicker        android:id="@+id/datePicker1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:calendarViewShown="false" />

其中calendarViewShown是控制样式是否显示日历,通常选择为false。

DatePicker 典型代码如下:

    Calendar calendar =Calendar.getInstance();        int year          =calendar.get(Calendar.YEAR);        int monthOfYear   =calendar.get(Calendar.MONTH);        int dayOfMonth    =calendar.get(Calendar.DAY_OF_MONTH);                datepicker.init(year, monthOfYear, dayOfMonth, new OnDateChangedListener(){            public void onDateChanged(DatePicker view, int year,                    int month, int day) {                String tmp = year + "/" + (month+1) + "/" + day;//这里的month返回的是索引,从0开始                Toast toast = new Toast(MainActivity.this);                toast = Toast.makeText(getApplicationContext(),                    tmp, Toast.LENGTH_SHORT);            toast.show();               }         });
