android - 单击EditText的TimePicker对话框

我已经有一个DatePicker，当用户单击EditText字段时，它会弹出

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();
            }
        });

我曾尝试以类似方式进行TimePicker，但无法使其正常工作。这是我尝试使其工作的尝试

 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();

            }
        });

像我为DatePicker所做的那样，是否不可能做到这一点？

单击此代码后，我什至尝试仅使TimePicker弹出。

      eReminderTime.setOnClickListener(new OnClickListener() {

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

由于某种原因，当我将其输入Android Studio时，“showDialog”被剔除。

谁能给我有关我要去哪里的提示？还是我只需要使用自定义DialogFragment？

最佳答案

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

您错过了+和选定的小时之间的""，因此setText方法仅包含一个字符串，因此您需要连接所有部分(可能不需要使用第一引号)。

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();

        }
    });

那应该可以解决第二个错误，因为您没有提供最后一个参数。
