Hello I'm trying to calculate user's sleeping hours of 7.5.the app should suggest that the user should be at bed at an exact time. For example, she chooses 7:00 Am as her waking time, the app will suggest that by 11:30 Am she should be going to bed What I tried so far is this:
public class TimepickerActivity extends Activity implements TimePickerDialog.OnTimeSetListener {
Button btn1, btn2;
TimePicker picker;
TextView tv;
private int hour;
private int minute;
static final int TIME_DIALOG_ID = 999;
#Override
public void onCreate( Bundle savedInstanceState ) {
super.onCreate(savedInstanceState);
setContentView( R.layout.activity_timepicker );
btn1 = (Button) findViewById (R.id.btnShow);
btn2 = (Button) findViewById (R.id.btnSleepingTime);
tv = (TextView) findViewById (R.id.textView1);
picker = (TimePicker) findViewById (R.id.timePicker1);
setCurrentTimeOnView();
addListenerOnButton();
}
// display current time
public void setCurrentTimeOnView() {
final Calendar c = Calendar.getInstance();
hour = c.get(Calendar.HOUR_OF_DAY);
minute = c.get(Calendar.MINUTE);
// set current time into textview
tv.setText( new StringBuilder().append(pad(hour))
.append(":").append(pad(minute)));
// set current time into timepicker
picker.setCurrentHour(hour);
picker.setCurrentMinute(minute);
}
public void addListenerOnButton() {
btn1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case TIME_DIALOG_ID:
// set time picker as current time
return new TimePickerDialog(this,
timePickerListener, hour, minute,false);
}
return null;
}
private TimePickerDialog.OnTimeSetListener timePickerListener =
new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int selectedHour,
int selectedMinute) {
hour = selectedHour;
minute = selectedMinute;
Calendar c = Calendar.getInstance();
c.add(Calendar.HOUR, - selectedHour);
c.add(Calendar.MINUTE, - selectedMinute);
// set current time into timepicker
picker.setCurrentHour(hour + 7);
picker.setCurrentMinute(minute + 30);
// set current time into textview
//tv.setText(new StringBuilder().append(pad(hour))
// .append(":").append(pad(minute)));
tv.setText( picker.getCurrentHour().toString() + ":" + picker.getCurrentMinute().toString() );
}
};
private static String pad(int c) {
if (c >= 10)
return String.valueOf(c);
else
return "0" + String.valueOf(c);
}
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
// TODO Auto-generated method stub
}
}
When I input 7:00 am as my waking time, the result is giving me 2:30 pm. But it should be 12:30 pm. Any help is appreciated thanks.
No, it's correct. If you input 7:00am + 7.5 hours = 14:30 = 2:30 am. The program is working correctly.
EDIT: you almost did it:
public class TimepickerActivity extends Activity implements TimePickerDialog.OnTimeSetListener {
private static final int SUB_HOUR = -7;
private static final int SUB_MINUTE = -30;
[...]
public void onTimeSet(TimePicker view, int selectedHour,
int selectedMinute) {
// Gets current time
Calendar c = Calendar.getInstance();
// Assign hour set in the picker
c.set(Calendar.HOUR, selectedHour)
c.set(Calendar.MINUTE, selectedMinute);
// Have Calendar calculate the substraction of hours and minutes
c.add(Calendar.HOUR, SUB_HOUR);
c.add(Calendar.MINUTE, SUB_MINUTE);
// Get the hour and the minute calculated
hour = c.get(Calendar.HOUR);
minute = c.get(Calendar.MINUTE);
[...]
Of course this means this previous assignment:
hour = selectedHour;
minute = selectedMinute;
is now useless and you can remove it.
By the way, you didn't take into account the day, e.g. choosing 1:30 am would return 6:00 pm but for the day before.
EDIT: I corrected my code.

I am working on a simple app in which i have taken two date pickers they subtract two dates and display the result. But i want that if the two dates are same like 06/04/2017 then two radio button should pop up for selecting full day and half day as soon as it calculates that the two dates are same.
how to do that?

I want to store a time in only 12 hours format.
the Time Picker is working perfectly but i just want to set AM or PM after the selected time in EditText.
this is my TimePicker theme
Here, my complete code
starttime.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Initialize a new time picker dialog fragment
DialogFragment dFragment = new TimePickerFragment();
// Show the time picker dialog fragment
dFragment.show(getActivity().getFragmentManager(),"Time Picker");
}
});

}
public void onTimeSet(TimePicker view, int hourOfDay, int minute){
// Do something with the returned time
TextView tv = (TextView) getActivity().findViewById(R.id.start_time);
tv.setText( hourOfDay + ":" + minute );
}
}
use this logic to find am pm
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
String AM_PM ;
if(hourOfDay < 12) {
AM_PM = "AM";
} else {
AM_PM = "PM";
}
}
try it will helps you,
public void onTimeSet(RadialPickerLayout view, int hourOfDay, int minute, int second) {
String hourString = "";
if(hourOfDay < 12) {
hourString = hourOfDay < 10 ? "0"+hourOfDay : ""+hourOfDay;
} else {
hourString = (hourOfDay - 12) < 10 ? "0"+(hourOfDay - 12) : ""+(hourOfDay - 12);
}
String minuteString = minute < 10 ? "0"+minute : ""+minute;
String secondString = second < 10 ? "0"+second : ""+second;
String am_pm = (hourOfDay < 12) ? "am" : "pm";
String time = hourString+":"+minuteString + " " + am_pm;
time.setTextColor(getResources().getColor(R.color.dark_blue));
time.setText(time);
}
This answer would be the best Option with few lines of code.
#Override
public void onTimeSet(TimePickerDialog view, int hourOfDay, int minute, int second)
{
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY,hourOfDay);
calendar.set(Calendar.MINUTE,minute);
calendar.set(Calendar.SECOND,second);
textViewStartTime.setText(startTimeFormat().format(calendar.getTime()));
}
public SimpleDateFormat startTimeFormat(){
return this.startTimeFormat = new SimpleDateFormat("hh:00 a");
}
OutPut will be :- 12:00 AM
I made a button to open a date and time picker, but a CheckBox must be checked in order to activate my button. Without the checkbox, it works fine, with the chekbox checked or unchecked, it's not opening the date picker. Can you tell me why?
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
pick_date = (Button) findViewById(R.id.pick_date);
tv_result = (TextView) findViewById(R.id.tvdate_result);
CheckBox fixed_date_flag = (CheckBox) findViewById(R.id.fixed_date);
final boolean checked = (fixed_date_flag).isChecked();
if(checked){
pick_date.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(NewActivity.this, NewActivity.this, year, month, day);
datePickerDialog.show();
}
});}
}
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth)
{
yearFinal = year;
monthFinal = month + 1;
dayFinal = dayOfMonth;
Calendar c = Calendar.getInstance();
hour = c.get(Calendar.HOUR);
minute = c.get(Calendar.MINUTE);
TimePickerDialog timePickerDialog = new TimePickerDialog(NewActivity.this, NewActivity.this, hour, minute, DateFormat.is24HourFormat(this));
timePickerDialog.show();
}
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute)
{
hourFinal = hourOfDay;
minuteFinal = minute;
tv_result.setText(
"year: " + yearFinal + "\n" +
"month: " + monthFinal + "\n" +
"day: " + dayFinal + "\n" +
"hour: " + hourFinal + "\n" +
"minute: " + minuteFinal);
}
}
your problem is very simple:
When creating the activity, your are checking if the checkbox is checked. If this value is true (but is not true) you add a click listener to the datePicker. So, the picker does not have a click listener! This means that when you "tap" the picker, it has no listener added, even if the checkbox is checked.
You must move the if statement inside the onClick method, like this:
EDITED:
pick_date.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
if((fixed_date_flag).isChecked()){
Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(NewActivity.this, NewActivity.this, year, month, day);
datePickerDialog.show();
}
}
});
Nevertheless, I think is a much better option to create a separated cass that implements OnClickListener interface, so in the constructor you can initialize the datepicker, instanciated as a privated variable of this new class, and on the onClick method you only call to .show() method (if the checkbox is checked, obbiusly)
Hope it helps!
I am not able to understand where am I doing mistake. I want to check it is a weekend or weekday. If it is weekend then it should prompt in the toast that it is a sunday or saturday weekend. I don't know what should I put in place of ??? mark. It should also display current date if it is weekend. Please, any one can help me. Thank you.

Once you get your date you can do like this and get the day and proceed with your logic.
Calendar c = Calendar.getInstance();
c.setTime(yourDate);
int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
I think that your variable dayOfWeek is the same variable as the parameter dayOfMonth
The above code must work
public DatePickerDialog.OnDateSetListener pickerListener = new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
if (selectedDay == 1 || selectedDay == 7) {
Toast.makeText(DateTimePickerActivity.this
, "You have selected weekend"
, Toast.LENGTH_SHORT).show();
view.updateDate(selectedYear,selectedMonth,selectedDay);
}
}
};
I had already tried the first two suggestions below, but I tried again and sincerely thanks for the help! The result is the same though. I´ll just edit the post to add more code info.
Hello there! I´m experimenting with a simple ToDo application and managed to change almost everything I wanted besides the date formatted that´s displayed once the user saves the task.
The task itself is added via the AddToDoActivity class which has the following resumed code:

Here´s the ToDoItem, that actually reads the info from AddToDoActivity:
public class ToDoItem {
public static final String ITEM_SEP = System.getProperty("line.separator");
public enum Priority {
LOW, MED, HIGH
};
public enum Status {
NOTDONE, DONE
};
public final static String TITLE = "title";
public final static String PRIORITY = "priority";
public final static String STATUS = "status";
public final static String DATE = "date";
public final static String FILENAME = "filename";
public final static SimpleDateFormat FORMAT = new SimpleDateFormat(
"dd/MM/yyyy HH:mm:ss", Locale.US);
private String mTitle = new String();
private Priority mPriority = Priority.LOW;
private Status mStatus = Status.NOTDONE;
private Date mDate = new Date();
ToDoItem(String title, Priority priority, Status status, Date date) {
this.mTitle = title;
this.mPriority = priority;
this.mStatus = status;
this.mDate = date;
}
// Create a new ToDoItem from data packaged in an Intent
ToDoItem(Intent intent) {
mTitle = intent.getStringExtra(ToDoItem.TITLE);
mPriority = Priority.valueOf(intent.getStringExtra(ToDoItem.PRIORITY));
mStatus = Status.valueOf(intent.getStringExtra(ToDoItem.STATUS));
try {
mDate = ToDoItem.FORMAT.parse(intent.getStringExtra(ToDoItem.DATE));
} catch (ParseException e) {
mDate = new Date();
}
}
public String getTitle() {
return mTitle;
}
public void setTitle(String title) {
mTitle = title;
}
public Priority getPriority() {
return mPriority;
}
public void setPriority(Priority priority) {
mPriority = priority;
}
public Status getStatus() {
return mStatus;
}
public void setStatus(Status status) {
mStatus = status;
}
public Date getDate() {
return mDate;
}
public void setDate(Date date) {
mDate = date;
}
// Take a set of String data values and
// package them for transport in an Intent
public static void packageIntent(Intent intent, String title,
Priority priority, Status status, String date) {
intent.putExtra(ToDoItem.TITLE, title);
intent.putExtra(ToDoItem.PRIORITY, priority.toString());
intent.putExtra(ToDoItem.STATUS, status.toString());
intent.putExtra(ToDoItem.DATE, date);
}
public String toString() {
return mTitle + ITEM_SEP + mPriority + ITEM_SEP + mStatus + ITEM_SEP
+ FORMAT.format(mDate);
}
public String toLog() {
return "Title:" + mTitle + ITEM_SEP + "Priority:" + mPriority
+ ITEM_SEP + "Status:" + mStatus + ITEM_SEP + "Date:"
+ FORMAT.format(mDate);
}
}
Oh well, after hours tweaking the
public final static SimpleDateFormat FORMAT = new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss", Locale.US);
method from ToDoItem, I still cannot successfully convert yyyy-MM-dd to dd/MM/yyyy.
First, I´ve tried the obvious, and changed the expression yyyy-MM-dd to dd/MM/yyyy.
After that, all I got after saving the task was today´s date, even though the date inputted on AddToDoActivity is months or years ahead. If I revert back to yyyy-MM-dd, the date shown on the Task List is the same inputted on AddToDoActivity.
Then I tried to change all mentions of dates on every class to match the exact format that I wanted.
That made everything look good on AddToDoActivity, but again, when I transported the date back to ToDoItem, the app just ignored the previously inputted date and showed today´s date again.
Can anyone help me with this one??
Thanks!!
You are calling setDateString with arguments in the order of year, month, day:
setDateString(c.get(Calendar.YEAR), c.get(Calendar.MONTH),
c.get(Calendar.DAY_OF_MONTH));
But your method has parameters in the order of day, month, year:
private static void setDateString(int dayOfMonth, int monthOfYear, int year) {
...
}
I also think you made some errors while copying your code into the question, since the setDateString method is duplicated and there is no setTimeString method.
Change:
setDateString(c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));
to:
setDateString(c.get(Calendar.DAY_OF_MONTH), c.get(Calendar.MONTH), c.get(Calendar.YEAR));
Modify the code as follows in the ToDoListAdapter file getView method
// TODO - Display Time and Date.
// Hint - use ToDoItem.FORMAT.format(toDoItem.getDate()) to get date and time String
final TextView dateView = (TextView) itemLayout.findViewById(R.id.dateView);
dateView.setText(ToDoItem.FORMAT.format(toDoItem.getDate()));
The output will be something similar the the following
