如何设置从DatePicker的对话框中的呼叫日期 [英] How to set the date from DatePicker dialog for multiple calls

问题描述

美好的一天，似乎无法找到一个解决方案。我有2个按钮，当pressed，打开一个datepickerdialog，但我现在的问题是，我怎么能设置他们在OnDateSet方法的相应按钮。我使用的日期DialogFragment，然后实施我的活动DateListener。我一直在使用getTag（），但在获取标签没有成功尝试。这里是我的尝试：

Good day, can't seem to find a solution for this. i have 2 buttons that when pressed, opens a datepickerdialog, but my problem now is , how can i set them to the appropriate button on OnDateSet method. I am using a DialogFragment for the date and then implementing the DateListener in my activity. I have tried using getTag() but no success in getting the tag. here is what i tried:

public void showfromDatePickerDialog(View v) {
        DialogFragment dateFragment = new DateDialogFragment();
        dateFragment.show(getSupportFragmentManager(), "fromdatePicker");
    }

    public void showtoDatePickerDialog(View v) {
        DialogFragment dateFragment = new DateDialogFragment();
        dateFragment.show(getSupportFragmentManager(), "todatePicker");
    }


        public void onDateSet(DatePicker view, int year, int month, int day) {

        StringBuilder builder = new StringBuilder();
        builder.append(day).append("-")
               .append(month).append("-")
               .append(year);

        String text= builder.toString();

        if(view.getTag().toString().equals("fromdatePicker")) { // error here

            Log.d(TAG, "got here" + text);
            fromdate.setText(text);
        }


        if(view.getTag() == "todatePicker") {
            todate.setText(text);
        }

任何想法如何实现这一点？我不断看到有关使用2种不同的DialogFragment一流的解决方案，但我猜测应该有另一种方式。还是我错了？谢谢

any ideas how to implement this? i keep seeing solutions about using 2 different DialogFragment class but am guessing there should be another way. or am i wrong? Thank you

推荐答案

好吧，我对这些周围的工作。它可以是对这个问题的人的帮助。如果稍有不正确，请让我知道，我可以改变它。但是这是我做过什么来解决这个问题。

ok, i have a work around for these. which can be helpful for anyone with this problem. if its slightly incorrect please let me know and i can change it. but this is what i did to solve this issue.

在DateSet：

  public void onDateSet(DatePicker view, int year, int month, int day) {

        StringBuilder builder = new StringBuilder();
        builder.append(day).append("-")
               .append(month).append("-")
               .append(year);

        String text= builder.toString();

FragmentManager fragmanager = getSupportFragmentManager();

      if(fragmanager.findFragmentByTag("fromdatePicker") != null) {

            Log.d(TAG, "got here" + text);
            fromdate.setText(text);
        }



       // if(view.getTag() == "todatePicker") {
  if(fragmanager.findFragmentByTag("todatePicker") != null) {
            todate.setText(text);
        }

这样你可以使用多个调用同一dateListener并设置适当的日期基础上调用对话框中显示时所通过的标签。

that way you can use the same dateListener for multiple calls and set the date appropriately based on the tag that was passed when calling show on the dialog.
