android - 单击 EditText 的 TimePicker 对话框

Question

我已经有一个 DatePicker 当用户点击 EditText 字段时弹出

eReminderDate.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();
                int mYear = mcurrentDate.get(Calendar.YEAR);
                int mMonth = mcurrentDate.get(Calendar.MONTH);
                int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

                DatePickerDialog mDatePicker;
                mDatePicker = new DatePickerDialog(AddReminder.this, new OnDateSetListener() {
                    public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) {
                        // TODO Auto-generated method stub
                    /*      Your code   to get date and time    */
                        selectedmonth = selectedmonth + 1;
                        eReminderDate.setText("" + selectedday + "/" + selectedmonth + "/" + selectedyear);
                    }
                }, mYear, mMonth, mDay);
                mDatePicker.setTitle("Select Date");
                mDatePicker.show();
            }
        });

我试过用类似的方式做一个 TimePicker 但无法让它工作。这是我让它工作的尝试

 eReminderTime.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Calendar mcurrentTime = Calendar.getInstance();
                int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
                int minute = mcurrentTime.get(Calendar.MINUTE);
                TimePickerDialog mTimePicker;
                mTimePicker = new TimePickerDialog(AddReminder.this, new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                        eReminderTime.setText( ""selectedHour + ":" + selectedMinute);
                    }
                }, hour, minute);
                mTimePicker.setTitle("Select Time");
                mTimePicker.show();

            }
        });

是否不可能像我为 DatePicker 所做的那样做它？

一旦使用此代码单击 EditText 字段，我什至尝试弹出 TimePicker 。

      eReminderTime.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            showDialog(TIME_DIALOG_ID);
        }
    });

出于某种原因，当我将其输入 Android Studio 时，“showDialog”被计分了。

谁能给我提示我哪里出错了？还是我只需要使用自定义 DialogFragment？

eReminderTime.setText( "" + selectedHour + ":" + selectedMinute);

您缺少+中间""和选定的时间，setText方法只需要一个字符串，因此您需要连接所有部分（第一个引号可能是不必要的）。

eReminderTime.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Calendar mcurrentTime = Calendar.getInstance();
            int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
            int minute = mcurrentTime.get(Calendar.MINUTE);
            TimePickerDialog mTimePicker;
            mTimePicker = new TimePickerDialog(AddReminder.this, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                    eReminderTime.setText( selectedHour + ":" + selectedMinute);
                }
            }, hour, minute, true);//Yes 24 hour time
            mTimePicker.setTitle("Select Time");
            mTimePicker.show();

        }
    });

这应该可以解决您的第二个错误，您没有提供最后一个参数。 TimePickerDialog 构造函数

为什么不以可重复使用的方式编写？

创建 SetTime 类：

class SetTime implements OnFocusChangeListener, OnTimeSetListener {   

       private EditText editText;
       private Calendar myCalendar;

       public SetTime(EditText editText, Context ctx){
           this.editText = editText;
           this.editText.setOnFocusChangeListener(this);
           this.myCalendar = Calendar.getInstance();

       }

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            // TODO Auto-generated method stub
            if(hasFocus){
                int hour = myCalendar.get(Calendar.HOUR_OF_DAY);
                int minute = myCalendar.get(Calendar.MINUTE);
                new TimePickerDialog(ctx, this, hour, minute, true).show();
            }
        }

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            // TODO Auto-generated method stub
            this.editText.setText( hourOfDay + ":" + minute);
        }

    }

然后从 onCreate 函数调用它：

    EditText editTextFromTime = (EditText) findViewById(R.id.editTextFromTime);
    SetTime fromTime = new SetTime(editTextFromTime, this);

您可以在edittext的onclick侦听器中使用以下代码

  TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this,
    new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay,
                              int minute) {

            tv_time.setText(hourOfDay + ":" + minute);
        }
    }, hour, minute, false);
     timePickerDialog.show();

我扩展了@Sumoanand 很好的可重用解决方案，以在多次更改时间时支持焦点更改和单击侦听器。还更新选择器日历以记住上次选择的时间 + 格式化 HH:mm

public class TimeSetter implements View.OnFocusChangeListener, TimePickerDialog.OnTimeSetListener, View.OnClickListener {

    private EditText mEditText;
    private Calendar mCalendar;
    private SimpleDateFormat mFormat;

    public TimeSetter(EditText editText){
       this.mEditText = editText;
       mEditText.setOnFocusChangeListener(this);
       mEditText.setOnClickListener(this);
    }

    @Override
    public void onFocusChange(View view, boolean hasFocus) {
        if (hasFocus){
            showPicker(view);
        }
    }

    @Override
    public void onClick(View view) {
        showPicker(view);
    }

    private void showPicker(View view) {
        if (mCalendar == null)
            mCalendar = Calendar.getInstance();

        int hour = mCalendar.get(Calendar.HOUR_OF_DAY);
        int minute = mCalendar.get(Calendar.MINUTE);

        new TimePickerDialog(view.getContext(), this, hour, minute, true).show();
    }

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        mCalendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
        mCalendar.set(Calendar.MINUTE, minute);

        if (mFormat == null)
            mFormat = new SimpleDateFormat("HH:mm", Locale.getDefault());

        this.mEditText.setText(mFormat.format(mCalendar.getTime()));
    }

}

onCreate 的用法：

EditText timeEditText = (EditText) rootView.findViewById(R.id.timeText);
new TimeSetter(timeEditText);

我不知道这是否对你有用，它对我有用。

为日期/时间选择器对话框创建一个方法。

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {

    // when dialog box is called, below method will be called.
    // The arguments will be working to get the Day of Week to show it in a special TextView for it.

    public void onDateSet(DatePicker view, int selectedYear,
                          int selectedMonth, int selectedDay) {
        String year1 = String.valueOf(selectedYear);
        String month1 = String.valueOf(selectedMonth + 1);
        String day1 = String.valueOf(selectedDay);
        delivDate.setText(month1 + "/" + day1 + "/" + year1);
        delivDay.setText(DateFormat.format("EEEE", new Date(selectedYear, selectedMonth, selectedDay - 1)).toString());
    }
};

然后，无论你想去哪里，你都可以像这样

public void setDateOnClick (View view) {
    Calendar cal = Calendar.getInstance();

    DatePickerDialog datePicker = new DatePickerDialog(this, datePickerListener,
            cal.get(Calendar.YEAR),
            cal.get(Calendar.MONTH),
            cal.get(Calendar.DAY_OF_MONTH));
    //Create a cancel button and set the title of the dialog.
    datePicker.setCancelable(false);
    datePicker.setTitle("Select the date");
    datePicker.show();
}

希望你找到这个作为你的解决方案。

你没有把最后一个参数放在TimePickerDialog.

{
public TimePickerDialog(Context context, OnTimeSetListener listener, int hourOfDay, int minute,
            boolean is24HourView) {
        this(context, 0, listener, hourOfDay, minute, is24HourView);
    }
}

这是的代码TimePickerclass。它需要一个布尔参数is24HourView

对我来说，如果我单击 dpFlightDate 编辑文本不止一次，对话框就会出现不止一次。如何避免此对话框仅出现一次，并且如果用户第二次单击该对话框，则该对话框不得再次出现，即如果对话框在屏幕上？

          // perform click event on edit text
            dpFlightDate.setOnClickListener(new View.OnClickListener() {

综上所述，EditText 仍然需要focusable="false"xml 中的属性，以防止键盘弹出。
