I'm using multiple textviews with onclick listeners that direct me to a TimePicker Dialog.
However I cannot seem to know how to write the code after reading the tutorials,
textview1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
textview2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
To show the dialog:
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case TIME_DIALOG_ID:
return new TimePickerDialog(this,
mTimeSetListener, mHour, mMinute, true);
}
return null;
}
and finally,
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(android.widget.TimePicker view,
int hourOfDay, int minute) {
mHour = hourOfDay;
mMinute = minute;
}
};
now, to .setText for the textview that CALLED the timepicker after the TimePickerDialog.OnTimeSetListener callback, how should I write the code?
The answer is very simple but I lack OOP knowledge and still learning.
Thanks...
You need to use a global varible. say,String fromWhere="";
now,
textview1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
fromWhere="textview1";
showDialog(TIME_DIALOG_ID);
}
});
textview2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
fromWhere="textview2";
showDialog(TIME_DIALOG_ID);
}
});
...
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(android.widget.TimePicker view,
int hourOfDay, int minute) {
if(fromWhere.equals(textview1))
// set hour and minute to according variable and textview
else if(fromWhere.equals(textview2))
// set hour and minute to according variable and textview
.. //so on for others
//mHour = hourOfDay;
//mMinute = minute;
fromWhere="";
}
};
create a member variable (say int whichViewClicked = 0) in your class to keep track of the textview clicked to bring-up the time-picker.
Now if you click textview1 set whichViewClicked = 1, if textview2 is clicked set whichViewClicked = 2 and so on. In the onTimeSet() method check the value of whichViewClicked and set the textview text accordingly
Use EditText and we can get time pikker long press on edit text.
EditText timeDisplay=(EditText)findViewById(R.id.timeDisplay);
timeDisplay.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});

I have a custom Dialog Fragment and I need to display an Alert dialog inside it.
Is it possible to do without closing the Dialog fragment?
When I do it with the context provided for the Dialog fragment it just closes the Dialog fragment and open the Alert dialog.
case R.id.deleteButton:
new AlertDialog.Builder(context)
.setTitle(context.getResources().getString(R.string.discard_changes))
.setIcon(android.R.drawable.ic_dialog_alert)

onItemClickListener.onItemClick(Device, DELETE_DOC);
dismiss();
})
.setNegativeButton(android.R.string.no, null).show();
break;

the above code is full fragment code with gialog innerclass too. im a beginner can you gys help me out of it?
and actually what i need is i have to click the from and to area in tab view fragment. after slecting it opens a dialog with search filter and listview. after clicking any list item it should diaplay in textview on parent fragment and after that i should be able wo pass the value to next fragment using put intent method.
currently im getting null value when i pass it to the next fragment.
i dont know why.
i have attached an image to get you the clear view. please check it.see here
Here is my code, in my ListViewAdapter. I want to show a timePicker to set time for my Adapter. But a cannot solve my onTimeSet
p is my Adapter
assert btnLeft != null;
btnLeft.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
TimePickerDialog mTimePicker;
mTimePicker = new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
p.setOnHour(hourOfDay);
p.setOnMinutes(minute);
btnLeft.setText(hourOfDay + " : " + minute);
}
}, p.getOnHour(), p.getOnMinutes(), false);
mTimePicker.setTitle("Select Time");
mTimePicker.show();
notifyDataSetChanged();
}
According to the docs, OnTimeSetListener calls onTimeSet() when
... the user is done setting a new time and the dialog has closed.
You need to use an OnTimeChangedListener with the onTimeChanged() method.
I am trying to follow along this tutorial: http://www.learn-android-easily.com/2013/01/using-timepickerdialog-and.html
However, showDialog cannot be resolved because I am using a fragment. How can I use a DateTime Picker Dialog inside of a class that extends a fragment?
Thanks.
EDIT: Show code:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.date_and_time_picker);
// get the references of buttons
btnSelectDate=(Button)findViewById(R.id.buttonSelectDate);
btnSelectTime=(Button)findViewById(R.id.buttonSelectTime);
// Set ClickListener on btnSelectDate
btnSelectDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Show the DatePickerDialog
showDialog(DATE_DIALOG_ID);
}
});
// Set ClickListener on btnSelectTime
btnSelectTime.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Show the TimePickerDialog
showDialog(TIME_DIALOG_ID); //not resolved in fragment
}
});
}
This is working for me in a fragment
Time currDate = new Time(Time.getCurrentTimezone());
currDate.setToNow();
DatePickerDialog d = new DatePickerDialog(this, datePickerListener,
currDate.year, currDate.month, currDate.monthDay);
d.show();
private DatePickerDialog.OnDateSetListener datePickerListener =
new DatePickerDialog.OnDateSetListener()
{
public void onDateSet(DatePicker view, int selectedYear, int selectedMonth, int selectedDay)
{
// Do as you need
}
};
So I made an Activity with textViews, editTexts, date dialog and time dialog picker. plus a button.
I used this to get the Date/Time dialogs to work:
public class RainbowBookActivity extends Activity {
private static final int DATE_DIALOG_ID=1; // for date
private static final int TIME_DIALOG_ID=2; // for month
private int d,mo,y,h,m; // for date & month variables

Now I would some how like to get this in there so I can have a button that transferes info from the editTexts:
EditText inputName;
EditText inputRoom;
public void onCreate1(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_rainbowbook);
inputName = (EditText) findViewById(R.id.editText1);
inputRoom = (EditText) findViewById(R.id.editText2);
Button btnNextScreen = (Button) findViewById(R.id.button3);
//Listening to button event
btnNextScreen.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
//Starting a new Intent
Intent nextScreen = new Intent(getApplicationContext(), BookingsActivity.class);
//Sending data to another Activity
nextScreen.putExtra("name", inputName.getText().toString());
nextScreen.putExtra("room", inputRoom.getText().toString());
Log.e("n", inputName.getText()+"."+ inputRoom.getText());
startActivity(nextScreen);
}
});
}
I cant seem to figure this out and am hoping someone can help me. Thanks.

BookingsActivity:
public class BookingsActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bookings);
TextView Name = (TextView) findViewById(R.id.textView2);
TextView Room = (TextView) findViewById(R.id.textView3);
Button btnClose = (Button) findViewById(R.id.btnClose);
Intent i = getIntent();
// Receiving the Data
String name = i.getStringExtra("name");
String room = i.getStringExtra("room");
Log.e("Bookings", name + "." + room);
// Displaying Received data
Name.setText(name);
Room.setText(room);
// Binding Click event to Button
btnClose.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
//Closing SecondScreen Activity
finish();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_bookings, menu);
return true;
}
}
maybe this in your BookingActivity
Bundle b = i.getExtras();
String name = b.getString("name", "default name");
String room = b.getString("room", "default room");
edit:
also, launche BookingActivity with startActivityForResult() so you can get data back from it later when you're done with it.
EDIT:
examples of startActivityForResult can be found How to return a result (startActivityForResult) from a TabHost Activity? and http://android.rahulblogs.com/android-startactivityforresult-example/
