如何在TextViewItem被点击时获取DatePicker弹出

我是Eclipse新手，运行Juno。当我试图在文本项目上实现日期选择器时，我碰到了开发移动应用程序的墙。我已经阅读了类似的问题从stackoverflow和应用的答案，但它似乎并没有为我工作。我一直在做出改变，我完全失去了。我尝试添加日历小部件，但它比屏幕大，所以我只想显示日历而不是日历。如何在TextViewItem被点击时获取DatePicker弹出

我需要我的用户能够选择他们希望旅行的日期，并且当单击搜索按钮时，表单中的条目将用于显示他们可以预订的可用巴士的列表。请在下面找到我的代码，没有帮助太少。

抱歉，我现在看着我们的代码。你已经实现了这一切。什么不工作？ – 2014-11-05 06:10:28

步骤1

为UR的TextView创建onClickListener

步骤2

在onClickListener使用我的代码，我已用于datepickerdialog

inOnClick方法

setDate();

的setDate方法：

public void setDate() { 
    new DatePickerDialog(add_task_frag.this, d, 
      calender.get(Calendar.YEAR), calender.get(Calendar.MONTH), 
      calender.get(Calendar.DAY_OF_MONTH)).show(); 
} 

DatePickerDialog.OnDateSetListener d = new DatePickerDialog.OnDateSetListener() { 

    @Override 
    public void onDateSet(DatePicker arg0, int year, int month, int day) { 

     calender.set(Calendar.YEAR, year); 
     calender.set(Calendar.MONTH, month); 
     calender.set(Calendar.DAY_OF_MONTH, day); 
     updatedate(); 

    } 
};

updatedate（）方法：

public void updatedate() { 
    textview.setText(format.format(calender.getTime())); 
}

也在你的xml中，你必须设置clickabale属性为true为你的textview – 2014-11-05 06:14:53
