Java android应用程序中日期选择器的问题

嗨，我的应用程序我放置了两个编辑文本框，当我触摸它时，日期选择器对话框就会出现

现在的问题是，当我触摸第一个编辑框时，对话框打开，设置后，它显示在EditText1。然后，当我触摸第二个编辑框时，对话框打开，在设置其他日期后，它不会显示在EditText2中，而是显示在EditText1中，并且前一个日期会更改

我希望日期显示在相应的框中

下面是我的代码

{
    et1 =(EditText)findViewById(R.id.widget29);
    et1.setHint("DOB");
    et2 =(EditText)findViewById(R.id.widget32);
    et2.setHint("DOF");

    et1.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            showDialog(DATE_DIALOG_ID);
        }
    });

    et2.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            showDialog(DATE_DIALOG_ID);
        }
    });


 // get the current date
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

}


private void updateDisplay()
{
    this.et1.setText(
            new StringBuilder()
                    // Month is 0 based so add 1
                    .append(mMonth + 1).append("-")
                    .append(mDay).append("-")
                    .append(mYear).append("-"));
}


private void updateDisplay1()
{
    this.et2.setText(
        new StringBuilder()
                // Month is 0 based so add 1
                .append(mMonth + 1).append("-")
                .append(mDay).append("-")
                .append(mYear).append("-"));
}

private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener()
    {
        public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth) 
        {
            mYear = year;
            mMonth = monthOfYear;
            mDay = dayOfMonth;
            updateDisplay();
        }
    };



    private DatePickerDialog.OnDateSetListener mDateSetListener1 = new DatePickerDialog.OnDateSetListener()
    {
        public void onDateSet(DatePicker view, int year,
                              int monthOfYear, int dayOfMonth) {
            mYear = year;
            mMonth = monthOfYear;
            mDay = dayOfMonth;
            updateDisplay1();
        }
    };

    @Override
    protected Dialog onCreateDialog(int id) 
    {
       switch (id) 
       {
          case DATE_DIALOG_ID:
          return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
       }
       return null;
    }
}

下面是我在这里面临的更多问题

每当我触摸编辑文本框时，键盘也会打开如何隐藏键盘

在编辑文本框中，我希望订单被视为年/月/日期

是否有任何方法可以更改日期选择器对话框，如下图所示

请在这方面帮助我

您正在为两种显示对话框方法设置相同的id

et1.setOnClickListener(new View.OnClickListener()
{
    @Override
    public void onClick(View v)
    {
        showDialog(DATE_DIALOG_ID);
    }
});

et2.setOnClickListener(new View.OnClickListener()
{
    @Override
    public void onClick(View v)
    {
        showDialog(DATE_DIALOG_ID);
    }
});

…而您的开关/机箱块只有一个“机箱”

   switch (id) 
   {
      case DATE_DIALOG_ID:
      return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
   }

至于其他问题，请将它们拆分为单独的问题。

@Venky感谢您的代码对我们的帮助，但我想知道，这个showDialog已经被删除了，那么如何使用Dialog完成同样的事情呢fragmentas@Venky感谢您的代码对我们的帮助，但是我想知道这个showDialog已经被删除了，所以如何使用Dialog fragmentas来做同样的事情呢
