两个日期选择器片段 - 如何分别编辑日期？

Question

我正在学习日期选择器 Android 教程。不幸的是，在这样做之后，我意识到它只适用于我的一个文本字段，老实说，我不知道如何将它应用到另一个文本字段，DateEdit2。也就是说，单击 DateEdit1 或 DateEdit2 我编辑 DateEdit1。我知道这是来自设置日期的功能，但是任何尝试更改或将按钮作为参数传递都会导致错误，因为这些方法无法以这种方式进行编辑。有什么想法吗？

代码如下：

 public void showTruitonDatePickerDialog(View v) {
        DialogFragment newFragment = new DatePickerFragment();
        newFragment.show(getSupportFragmentManager(), "datePicker");
    }

    public static class DatePickerFragment extends DialogFragment implements
            DatePickerDialog.OnDateSetListener {

        @Override
        public Dialog onCreateDialog(Bundle savedInstanceState) {
            // Use the current date as the default date in the picker
            final Calendar c = Calendar.getInstance();
            int year = c.get(Calendar.YEAR);
            int month = c.get(Calendar.MONTH);
            int day = c.get(Calendar.DAY_OF_MONTH);

            // Create a new instance of DatePickerDialog and return it
            return new DatePickerDialog(getActivity(), this, year, month, day);
        }

        public void onDateSet(DatePicker view, int year, int month, int day) {
            // Do something with the date chosen by the user
            DateEdit1.setText(DateEdit1.getText() + " " + day + "/" + (month + 1) + "/" + year);
        }
    }

提前谢谢你，约翰

Answer 1

在 activity 中创建全局 public boolean isDateEdit1;。

在 DateEdit1 的 onClickListener 中，在调用 showTruitonDatePickerDialog(View v) 之前，设置 isDateEdit1 = true;。

在 DateEdit2 的 onClickListener 中，在调用 showTruitonDatePickerDialog(View v) 之前，设置 isDateEdit1 = false;。

然后，在 onDateSet:

    public void onDateSet(DatePicker view, int year, int month, int day) {
        if(getActivity.isDateEdit1){
          DateEdit1.setText(""+day + "/" + (month + 1) + "/" + year);
          return;
        }
        DateEdit2.setText("" + day + "/" + (month + 1) + "/" + year);
    }

我创建了另一个 class，它使用另一个名称扩展了 DialogFragment，并使用了不同的函数：

public void showTruitonDatePickerDialog(View v) {
    DialogFragment newFragment = new DatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker");
}

public void datePickerDialog(View v) {
    DialogFragment newFragment = new SecondDatePickerFragment();
    newFragment.show(getSupportFragmentManager(), "datePicker1");
}

public static class DatePickerFragment extends DialogFragment implements
        DatePickerDialog.OnDateSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
        DateEdit1.setText(DateEdit1.getText() + " " 
              + day + "/" + (month + 1) + "/" + year);
    }
}

public static class SecondDatePickerFragment extends DialogFragment implements
        DatePickerDialog.OnDateSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        // Create a new instance of DatePickerDialog and return it
        return new DatePickerDialog(getActivity(), this, year, month, day);
    }

    public void onDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
        DateEdit2.setText(DateEdit2.getText() + " "
            + day + "/" + (month + 1) + "/" + year);
    }
}

它不是很好，但对我有用。因此，在第一个 onClickListener() 上调用 showTruitonDatePickerDialog()，然后在第二个 onClickListener() 上调用 datePickerDialog()。
