[Tutorial]How to use Timer Function - C++ or Other Android Development Languages

You may need a timer......for what????
okay....in this guide i'm showing you to how to switch to the next layout maybe.....
This is not originally a my code.....Just sharing with you
Read Carefully and Realize
1- Start your mono android project
2- Go to your activity, add the following
Code:
using System.Timers;
//This is how my code looked like after adding it,
Code:
[FONT="Arial Black"][B]using System;
using System.Timers;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
namespace Timer
{
[Activity(Label = "Timer", MainLauncher = true, Icon = "@drawable/icon")]
public class Activity1 : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
}
}
}[/B][/FONT]
3- Now create a another layout
Resources---Layout----Right Click---Add New Item
Choose Android Layout
Name the layout whatever you want. (I named it to Main2)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
4- Within the brackets after Public Class, add below,
Code:
int count = 1;
System.Timers.Timer timer1;
//for the the timer1, you can replace anything you want to refer your timer
5- After this code ,
Code:
SetContentView(Resource.Layout.Main);
Type this,
Code:
timer1 = new System.Timers.Timer(200);
timer1.Interval = 100;
timer1.Elapsed += new ElapsedEventHandler(OnTimeEvent);
timer1.Enabled = true;
timer1.Start();
6- Now after the code below,
Code:
int count = 1;
System.Timers.Timer t1;
type this,
Code:
private void OnTimeEvent(object source, ElapsedEventArgs e)
{
RunOnUiThread(delegate
{
count++;
if (count == 200)
{
SetContentView(Resource.Layout.Main2);
timer1.Enabled = false;
}
});
}
this code is running in background to whether check if the timer reached to 200 or not, when it reached, then the Main2 layout will load and timer will be disabled.
7- All done now, run it on AVD or your phone. :laugh::laugh::laugh::laugh:
Happy CODING!

Alternative
If you just wanna go.from one.class to another after a certain amount of time(This is your purpose, i believe). Then instead of.writing such a huge amount of code. You can just make it sleep for 200 millisecond and start an intent.
Like
Code:
sleep(200);
Intent a= new Intent(existing class.this, thenextclass.class);
startActivity(a);
Also if you want you can surround it with a try and catch method.
I think this will do.
And its a class i.e a .java file. Not a layout.
A layout is your .xml file..

I think the point of using a timer was so that program execution wasn't halted and other things would/could continue. If you use sleep then it blocks the thread and no further execution takes place till it continues
Just out of curiosity, ScatteredHell, why would you not just set the interval to 20,000 (20 seconds)? I don't see any benefit to the counter method you've used.

---

That is the point you see...
You should add all the codes before your timer thread.
then,
Code:
try{sleep(200)}
catch(InterruptedException a){
a.printStackTrace()}
finally{
your intent
}
surrounded by a thread ofcourse

@hiphop
you saying in JAVA, maybe there are few other ways to do that. Man in XAMARIN android layout is not a xml file.....use this before talking
layout is .axml and activity is .cs
this is for C# man
@Archer
I didn't have any purpose, I only wanted to tell this to starters....So that's
Users must be creative to use this

---

As far as i know.
xamarin is for ios.
(correct me, if i am wrong)..
And sorry, i forgot that you were talking about c#

You should definitely use a timer to wait, not sleep. If you use sleep then it will block the thread it's in, unless you put it in a separate thread and have a callback function for when it's complete. That's exactly the point of using a timer. You create the timer and assign a callback function to execute once the timer triggers. The UI will continue to work during that time. No separate thread needed.

t1
Hello.
Where did you use the t1 again, or the count in the OnCreate Bundle?
I want to use the timer to fil a progressbar, but I don't know where should I declare the variables.
Like this:
HTML:
ProgressBar progBar = FindViewById<ProgressBar> (Resource.Id.progressBar1);
P.S. :
Ohh and I forgot to mention that, but my application is closing after I launch it.

Sorry for the late reply. I use count inside of Activity 1 otherwise you cannot use it if you declared it in OnCreateBundle. I didn't play with xamarin in a long time, so sorry I don't remember. But i'm pretty sure you can find it in examples.
Go to project properties. There are 2 options. I exactly don't remember their title, when you tick those two options. app will run without the need of xamarin runtime on your phone. When you normally debug the app, runtime is automatically installed in your device, so it won't take long to debug as only app contain the code.
