I have followed the xamarin Timepicker tutorial link to create a Timepickerdialog
within an Activity
. It works great.
I need to to do the same in a fragment
but have failed to make it work.
Can someone please show me how to do it using a fragment? Any guildelines or links or advice.
I'm using Xamarin Andriod
.
Thank you in advanced.
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView android:id="@+id/timeDisplay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=""/>
<Button android:id="@+id/pickTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Change the time"/>
</LinearLayout>
MainActivity.cs
private TextView time_display;
private Button pick_button;
private int hour;
private int minute;
const int TIME_DIALOG_ID = 0;
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
// Set our view from the "Main" layout resource
SetContentView (Resource.Layout.Main);
// Capture our View elements
time_display = FindViewById<TextView> (Resource.Id.timeDisplay);
pick_button = FindViewById<Button> (Resource.Id.pickTime);
// Add a click listener to the button
pick_button.Click += (o, e) => ShowDialog (TIME_DIALOG_ID);
// Get the current time
hour = DateTime.Now.Hour;
minute = DateTime.Now.Minute;
// Display the current date
UpdateDisplay ();
}
// Updates the time we display in the TextView
private void UpdateDisplay ()
{
string time = string.Format ("{0}:{1}", hour, minute.ToString ().PadLeft (2, '0'));
time_display.Text = time;
}
private void TimePickerCallback (object sender, TimePickerDialog.TimeSetEventArgs e)
{
hour = e.HourOfDay;
minute = e.Minute;
UpdateDisplay ();
}
protected override Dialog OnCreateDialog (int id)
{
if (id == TIME_DIALOG_ID)
return new TimePickerDialog (this, TimePickerCallback, hour, minute, false);
return null;
}
Fragment.cs
//Everything same as Activity
//updated the following:
time_display = view.FindViewById<TextView>(Resource.Id.timeDisplay);
pick_button = view.FindViewById<Button>(Resource.Id.pickTime);
protected override Dialog OnCreateDialog(int id)
{
if (id == TIME_DIALOG_ID)
return new TimePickerDialog(this.Activity, TimePickerCallback, hour, minute, false);
return null;
}
Result:
Error 1.The name 'ShowDialog' does not exist in the current context.
Error 2.Fragement.OnCreateDialog(int)': no suitable method found to override.
Try this set of code to show the TimePickerDialog.
TimePickerDialog timePickerDialog = new TimePickerDialog(this.Activity, TimePickerCallback, hour, minute, false);
timePickerDialog.Show();
