第Android開發實現日期時間控件選擇1.2Layout中添加日期和時間控件

注意需要將控件的calendarViewShown指定為false及datePickerMode屬性指定為spinner

xmlversion="1.0"encoding="utf-8"

LinearLayoutxmlns:android="/apk/res/android"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="vertical"

DatePicker

android:id="@+id/dialog_datetime_date_picker"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:calendarViewShown="false"

android:datePickerMode="spinner"/

TimePicker

android:id="@+id/dialog_datetime_time_picker"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:calendarViewShown="false"

android:datePickerMode="spinner"/

/LinearLayout

二、新建DateTimeDialog

創建DateTimeDialog類是為了將方法封裝，以便我項目多次調用

publicclassDateTimeDialog{

}

2.1創建靜態方法

2.1.1創建SetDateDialog，用于選擇日期

publicstaticvoidSetDateDialog(Contextcontext,Activityactivity,TextViewtextView,String...title){

}

這里我們將引用控件的context、activity作為參數傳入方法中，方便我們動態加載Layout和指定AlertDialog彈出所在的Activity，避免彈出框無法顯示。

textView參數為需要綁定選擇的控件，并且在選擇之后，會將選擇的日期返回給textView

titile是可選參數，指定彈出框的標題，不指定的話，會默認為選擇日期

2.1.2SetDateDialog中綁定textView的click事件

給textView綁定事件后，在用戶點擊控件時即可執行相應的事件內容，在此我們需要的是用戶點擊控件時，彈出日期選擇框。

textView.setOnClickListener(view-{

AlertDialog.Builderbuilder=newAlertDialog.Builder(activity);

builder.setView(view1);

builder.create().show();

});

由于我們的控件中含有時間控件，需要隱藏

Viewview1=LayoutInflater.from(context).inflate(R.layout.dialog_datetime,null);

finalTimePickertimePicker=view1.findViewById(R.id.dialog_datetime_time_picker);

timePicker.setVisibility(View.GONE);

如果textView有默認值，則在彈出的時候需要將textView的日期帶入彈出框中

finalDatePickerdatePicker=view1.findViewById(R.id.dialog_datetime_date_picker);

Calendarcalendar;

StringstrDate=textView.getText().toString();

calendar=convertDateToCalendar(strDate);

datePicker.init(calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DATE),null);

設置彈出框的標題

if(title!=nulltitle.length0){

builder.setTitle(title[0]);

}else

builder.setTitle("選擇日期");

實現彈出框的按鈕事件：

點擊確定時，綁定值給textView，并關閉彈窗；點擊取消時，直接關閉天窗；點擊現在時，將當前時間傳給textView，并關閉彈窗。

builder.setPositiveButton("確定",(dialog,i)-{

//日期格式

intyear=datePicker.getYear();

intmonth=datePicker.getMonth()+1;

intdayOfMonth=datePicker.getDayOfMonth();

textView.setText(String.format(Locale.getDefault(),"%d年%d月%d日",year,month,dayOfMonth));

dialog.cancel();

});

builder.setNegativeButton("取消",(dialog,which)-dialog.cancel());

builder.setNeutralButton("現在",(dialog,i)-{

SimpleDateFormatsimpleDateFormat=newSimpleDateFormat("yyyy年M月d日",Locale.getDefault());//HH:mm:ss

//獲取當前時間

Datedate=newDate(System.currentTimeMillis());

textView.setText(simpleDateFormat.format(date));

dialog.cancel();

});

以下是完整代碼：

publicstaticvoidSetDateDialog(Contextcontext,Activityactivity,TextViewtextView,String...title){

textView.setOnClickListener(view-{

AlertDialog.Builderbuilder=newAlertDialog.Builder(activity);

Viewview1=LayoutInflater.from(context).inflate(R.layout.dialog_datetime,null);

finalDatePickerdatePicker=view1.findViewById(R.id.dialog_datetime_date_picker);

finalTimePickertimePicker=view1.findViewById(R.id.dialog_datetime_time_picker);

timePicker.setIs24HourView(true);

Calendarcalendar;

StringstrDate=textView.getText().toString();

calendar=convertDateToCalendar(strDate);

datePicker.init(calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DATE),null);

timePicker.setHour(calendar.get(Calendar.HOUR_OF_DAY));

timePicker.setMinute(calendar.get(Calendar.MINUTE));

timePicker.setVisibility(View.GONE);

//

datePicker.setCalendarViewShown(false);

//設置Date布局

builder.setView(view1);

if(title!=nulltitle.length0){

builder.setTitle(title[0]);

}else

builder.setTitle("選擇日期");

builder.setPositiveButton("確定",(dialog,i)-{

//日期格式

intyear=datePicker.getYear();

intmonth=datePicker.getMonth()+1;

intdayOfMonth=datePicker.getDayOfMonth();

textView.setText(String.format(Locale.getDefault(),"%d年%d月%d日",year,month,dayOfMonth));

dialog.cancel();

});

builder.setNegativeButton("取消",(dialog,which)-dialog.cancel());

builder.setNeutralButton("現在",(dialog,i)-{

SimpleDateFormatsimpleDateFormat=newSimpleDateFormat("yyyy年M月d日",Locale.getDefault());//HH:mm:ss

//獲取當前時間

Datedate=newDate(System.currentTimeMillis());

textView.setText(simpleDateFormat.format(date));

dialog.cancel();

});

builder.create().show();

});

}

同樣的方式我們再實現選擇日期時間的方法，具體不再贅述，上代碼：

publicstaticvoidSetDateTimeDialog(Contextcontext,Activityactivity,TextViewtextView,String...title){

textView.setOnClickListener(view-{

AlertDialog.Builderbuilder=newAlertDialog.Builder(activity);

Viewview1=LayoutInflater.from(context).inflate(R.layout.dialog_datetime,null);

finalDatePickerdatePicker=view1.findViewById(R.id.dialog_datetime_date_picker);

finalTimePickertimePicker=view1.findViewById(R.id.dialog_datetime_time_picker);

timePicker.setIs24HourView(true);

//

datePicker.setCalendarViewShown(false);

Calendarcalendar;

StringstrDate=textView.getText().toString();

calendar=convertDateToCalendar(strDate);

datePicker.init(calendar.get(Calendar.YEAR),calendar.get(Calendar.MONTH),calendar.get(Calendar.DATE),null);

timePicker.setHour(calendar.get(Calendar.HOUR_OF_DAY));

timePicker.setMinute(calendar.get(Calendar.MINUTE));

//設置Date布局

builder.setView(view1);

if(title!=nulltitle.length0){

builder.setTitle(title[0]);

}else

builder.setTitle("選擇時間");

builder.setPositiveButton("確定",(dialog,i)-{

//日期格式

intyear=datePicker.getYear();

intmonth=datePicker.getMonth()+1;

intdayOfMonth=datePicker.getDayOfMonth();

inthour=timePicker.getHour();

intmin=timePicker.getMinute();

//

timePicker.getSecond();

textView.setText(String.format(Locale.getDefault(),"%d年%d月%d日%d:%d",year,month,dayOfMonth,hour,min));

dialog.cancel();

});

builder.setNegativeButton("取消",(dialog,which)-dialog.cancel());

builder.setNeutralButton("現在",(dialog,i)-{

SimpleDateFormatsimpleDateFormat=newSimpleDateFormat("yyyy年M月d日HH:mm",Locale.getDefault());//HH:mm:ss

//獲取當前時間

Datedate=newDate(System.currentTimeMillis());

textView.setText(simpleDateFormat.format(date));

dialog.cancel();
