通过单击 EditText 获得 TimePicker 对话框

我已经有了一个 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();
}
});

我曾经尝试过用类似的方法做一个 TimePicker，但是无法让它工作。这是我想让它工作的尝试

 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();


}
});

Is it impossible to do it similar to the way I did it for DatePicker?

我甚至尝试过在用这段代码单击 EditText 字段时弹出一个 TimePicker。

      eReminderTime.setOnClickListener(new OnClickListener() {


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

For some reason when I entered that into Android Studio the 'showDialog' was scored out.

有人能告诉我哪里做错了吗？还是只能使用自定义对话框片段？

最佳答案 
eReminderTime.setText( "" + selectedHour + ":" + selectedMinute);

在 ""和选定时间之间缺少一个 +，setText方法只采用一个字符串，因此需要将所有部分连接起来(可能不需要第一个引号)。

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();


}
});

这应该可以修复第二个错误，因为您没有提供最后一个参数。 TimePickerDialog 构造函数

为什么不用可重用的方式编写呢？

Create SetTime class:

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);

I dont know if this will work for you, it works for me just fine.

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，无论你想在哪里，你都可以这样做

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();
}

希望你能找到解决办法。

e1.setText(day1 + "/" + (month1+1) + "/" + year1);

您还没有将最后一个参数放入 TimePickerDialog中。

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

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

您可以在编辑文本的 onclick 侦听器中使用下面的代码

  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();

setDateTimeField();


private void setDateTimeField() {

我扩展了@Sumoanand 的可重用解决方案，以支持焦点更改和在多次更改时单击侦听器。同时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()));
}


}

用法来自 onCreate:

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

对于我来说，如果我多次点击 dpFlightDate 编辑文本，定时器对话框就会出现多个对话框。 我如何避免这个对话框只出现一次，如果用户点击的第二次对话框必须不再出现即如果对话框在屏幕上？

          // perform click event on edit text
dpFlightDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// calender class's instance and get current date , month and year from calender
final Calendar c = Calendar.getInstance();
int mYear = c.get(Calendar.YEAR); // current year
int mMonth = c.get(Calendar.MONTH); // current month
int mDay = c.get(Calendar.DAY_OF_MONTH); // current day
// date picker dialog
datePickerDialog = new DatePickerDialog(frmFlightDetails.this,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
// set day of month , month and year value in the edit text
dpFlightDate.setText(dayOfMonth + "/"
+ (monthOfYear + 1) + "/" + year);


}
}, mYear, mMonth, mDay);
datePickerDialog.show();
}
});
tpFlightTime.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Use the current time as the default values for the picker
final Calendar c = Calendar.getInstance();
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
// Create a new instance of TimePickerDialog
timePickerDialog = new TimePickerDialog(frmFlightDetails.this, new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
tpFlightTime.setText( selectedHour + ":" + selectedMinute);
}
}, hour, minute, true);//Yes 24 hour time
timePickerDialog.setTitle("Select Time");
timePickerDialog.show();
}
});

在以上所有操作中，EditText 仍然需要 xml 中的 focusable="false"属性，以防止键盘弹出。
