Question

我搜索了很多，需要知道从日历中选择日期的最佳方式，我已经在尝试片段，例如

FragmentManager manager = getFragmentManager（）; FragmentTransaction transaction = manager.beginTransaction（）;

DialogFragment fragment = new DatePickerDialogFragment（MainActivity.this）; fragment.show（transaction，“date_dialog”）;

但是有关于进口的错误，因为它们相互矛盾我相信...... 真的需要一个出路，有没有人有一个很好的解决方案，请让我知道我需要它！

Answer 1

我喜欢用Dialog做到这一点。首先，在xml中的android:focusable="false"上设置EditText。

然后你可以尝试这样的事情：

yourEditText = (EditText) findViewById(R.id.yourEditTextID);
        yourEditText.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                // To show current date in the datepicker
                Calendar mcurrentDate = Calendar.getInstance();
                mYear = mcurrentDate.get(Calendar.YEAR);
                mMonth = mcurrentDate.get(Calendar.MONTH);
                mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

                DatePickerDialog mDatePicker = new DatePickerDialog(yourActivity.this, new OnDateSetListener() {
                    public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) {
                        Calendar myCalendar = Calendar.getInstance();
                        myCalendar.set(Calendar.YEAR, selectedyear);
                        myCalendar.set(Calendar.MONTH, selectedmonth);
                        myCalendar.set(Calendar.DAY_OF_MONTH, selectedday);
                        String myFormat = "dd/MM/yy"; //Change as you need
                        SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.FRANCE);
                        yourEditText.setText(sdf.format(myCalendar.getTime()));

                        mDay = selectedday;
                        mMonth = selectedmonth;
                        mYear = selectedyear;
                    }
                }, mYear, mMonth, mDay);
                //mDatePicker.setTitle("Select date");
                mDatePicker.show();
            }
        });

mYear，mMonth和mDay是全球性的。

Answer 2

您可以尝试这样的事情

DatePicker mDlgDatePicker = new DatePickerDialog(getActivity(), new OnDateSetListener() {
@Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
    mEdtxDate.setText(year + "-" + (monthOfYear + 1 < 10 ? "0" : "") + (monthOfYear + 1) + "-"
                            + (dayOfMonth < 10 ? "0" : "") + dayOfMonth);
                }
  }, 2014, 1, 1);
  mDlgDatePicker.show();

选择日期为默认日期的 KOTLIN 日期选择器

最初将此代码添加为全局范围，位于 onCreate() 之上或之外的某处

 //this will show default date as current date initially
 private val currentDate: Calendar = Calendar.getInstance()
 private var year = currentDate[Calendar.YEAR]
 private var month = currentDate[Calendar.MONTH]
 private var day = currentDate[Calendar.DAY_OF_MONTH]

在您的 TextView 上，添加此 OnClickListener：

 binding.tvDate.setOnClickListener {
     selectDate()
 }

这是您的 selectDate() 函数：

 private fun selectDate() {
 val mDatePicker = DatePickerDialog(
     this,
     { _, selectedYear, selectedMonth, selectedDay ->
         val myFormat = AppConstants.DateFormat.DF_dd_MM_yy
         val sdf = SimpleDateFormat(myFormat, Locale.getDefault())
         day = selectedDay
         month = selectedMonth
         year = selectedYear
         currentDate.set(year, month, day)
         binding.tvDate.text = sdf.format(currentDate.time)
     }, year, month, day
 )

 mDatePicker.show()
 mDatePicker.getButton(AlertDialog.BUTTON_POSITIVE)
     .setTextColor(ContextCompat.getColor(this, R.color.purple))

 mDatePicker.getButton(AlertDialog.BUTTON_NEGATIVE)
     .setTextColor(ContextCompat.getColor(this, R.color.purple))

}

这里。 DF_dd_MM_yyyy 是 const val DF_dd_MM_yyyy = "dd/MM/yyyy"
