Hi Guys,
I have been working on an open source MVVM framework for Android, and have just released it on Github. It is a development release, but is quite well documented. Those of you who are addicted to WPF goodness would really love the ability to do the same on Android.
Here it is on Github: RoboMVVM[^]
I am considering writing a tutorial about it on CodeProject soon when I have time for it. Meanwhile, please have a look and tell me what you think.
Regards,

Hi
Currently I am working on an application to set reminders on monthly basis. I am not able to provide the correct repeating interval for my alarmmanager. Pls provide info about the same. this is my code, but this will not raise alarm for Feb or months having 30 days. Also pls provide code to set yearly repeating alaram.
repeatTime=(AlarmManager.INTERVAL_DAY*31);
mAlarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, when.getTimeInMillis(), repeatTime, pi);
Thanks,
Sharath

You need to add logic to calculate how many days to add, depending on the number of days in the current month. Then each time your application runs it sgould reset the alarm to the new value.
|

|
|
|
As you are already (hopefully) aware, hard-coding numbers into your code is a bad idea.
When are you wanting the alarm set for (e.g., the last day of the month)?

I want to add Horizontal scroll only for my tabhost.
However we can add swipe able tab. but i don't want this. i want to swipe only the tabhost. not the tab content.
Thanks in advance.

According to my counting, the line you have marked is not line 39, as referenced in the error message. However, I suspect that the variable mTabHost has not been set to point to anything. Are you sure you get a valid reference returned in the following statement?
mTabHost = FindViewById<FragmentTabHost>(Resource.Id.tabhostN );
|
|
|
|

first of all thanks for ur attention.
i have it in "activity_main.axml" :
<android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tabhostN"
android:layout_width="match_parent"
android:layout_height="match_parent">
And the mTabHost isnot nulll in
mTabHost = FindViewById<FragmentTabHost>(Resource.Id.tabhostN );
Or
Possible to give me and C# xamarin example for doing the same i have done?
any further question?

Did you actually check the value of this variable at run time? It matters not what you write in your source code, the only way to be sure it works is to check it at the time of error. If it is not that variable that causes the error then it must be one of the others.
I also notice that you have this code within a try/catch block, but you eat the exception. This is really bad practice and leads to situations just such as this. Exceptions provide useful information, so make proper use of them.
|
|
|
|
|
i have used this for sample for that the catch is not complete.
at runtime the mtabHost is not null.
i have breakepoint in
mTabHost.AddTab(spec);
and the error occured in here.
thanks in advanced!
|
|
|
|
|
Then you need to establish what value is causing the exception. We cannot guess it from the information you have provided.
|
|
|
|
|
may i give ur the whole project for downloading?
thanks in advanced!
|
|
|
|
|
Sorry, no. You need to do the debugging and provide the required information.
