Android :: Eclipse Is Marking FindViewById(int) As Undefined
May 24, 2010
Eclipse is marking findViewById(int) as undefined; it was doing the same thing for getResources(), but I was able to get around that by calling context.getResources() instead (as seen below) and can't seem to find a similar workaround for findViewById.
Here is the code:
CODE:.....................
Is there another package I need to import for findViewById?

Wonder why do I get this error?
String srvcName = Context.TELEPHONY_SERVICE; TelephonyManager telephonyManager = (TelephonyManager)getSystemService(srvcName); String deviceId = telephonyManager.getDeviceId();

first of all: yes, I read all the other threads on this topic. And not only those from this site... (you see, i'm a little frustrated) Most of them come with the advice to use "android:id" instead of just "id" in the xml file. I did. From others, i learned, that View.findViewById works different than Activity.findViewById. I handled that, too.
in my location_layout.xml i use
<FrameLayout .... >
<some.package.MyCustomView ... />
<LinearLayout ... >
<TextView ...
android:id="@+id/txtLat" />.................

I use K-9 Mail for my hotmail account. When I mark emails as read on my phone I would like that to sync with my hotmail account.For some reason I can get it to delete the emails on the server, but I can't get it to mark it as read.

I have a unique situation I need assitance with...about 1.5 years ago I ripped all my cd's to my harddrive in mp3 format, for a thousand or so mp3's. My cd's have all since been stolen out of my car, and a week ago my hard drive crashed. I used a restore tool & was able to retrieve a lot of info from the drive, however none of the files have names on them, just 0001 0002 etc etc. Now my question. I have loaded all my music onto my htc incredible, and am looking for something like pandora which allows you to quickly mark a song as good or bad, and move onto the next. I want to sort through these to see which ones I want to keep, as I don't want to take the time to rename every song from every album as I usually only like 3-4 songs per album. So i want some music player that either I can assign them to a playlist, then sync the playlist to my pc, and sort through that way, or something that allows me to delete the song straight from the main screen. Now before anyone says yes you can delete using astro, or long clicking, what i'm trying to accomplish is to either delete the song, move the song, rate it, or simply mark it good or bad, in 1-2 clicks. If I have to go through screen after screen to delete or assign to a playlist with over 1000+ songs, it'll drive me crazy. I'd rather not do it on my PC as i'd like to do it while walking around wearing headphones.

If I want to mark the second item I'm doing the following code: This code is from my Adapter that extends ArrayAdapter :if (convertView == null) { LayoutInflater mInflater = (LayoutInflater)getContext( ).getSystem Service (Context.LAYOUT_INFLATER_SERVICE); convertView = mInflater.inflate(R.layout.channel_list, null); MyContent o = items.get(position); if (o != null) { TextView tt = (TextView) convertView. findViewById (R.id.toptext) ;TextView bt = (TextView) convertView.findViewById(R.id.bottomtext);if (tt != null) {tt.setText(o.Top()) ; if(bt != null){bt.setText(o.Bottom());} if(position == 2) { convertView.setBackground Color(R.color.selectem_color); return convertView;It will show the list view but mark every 9'th item after this item (the 11'th item 13'th and so on).Does anyone know what's the reason?

I have my work IMAP account set up in the Android e-mail application. It works fine, but every mail I send from the phone shows up as unread in the Sent folder, so when I access the account with other e-mail applications I have all these unread messages in the Sent folder. I have never had any e-mail applications mark Sent mail unread. Is there a way to prevent the Android mail client from marking sent unread?

I started learning Java and how to program for Android last night. So far I'm on this tutorial: developer.android.com/resources/tutorials/views/hello-tabwidget.html. Clearly these tutorials have been designed for people that already have experience with Java.
Despite the tutorial lacking all the required steps (for an absolute beginner with Java) and even having a typo, it seems I've figured everything out (which I'm really proud of :p). Except I cannot figure out how to fix TabHost tabHost = getTabHost(); which apparently is undefined.
I have one other error shown in the linked image below, but I don't see why.
Here is the linked image.

I have an error stating something like: The method foo() is undefined for the type bar(){}
Eclipse tells me that after entering this code:
CODE:...........
I'm not sure if this is the problem, but I have it located under....
CODE:......
I'm guessing it has a problem with "this." I'm still learning about Android so I'm going pretty basic.

I've created a test project with three identical classes that extend BroadcastReceiver, named
TestReceiverOne TestReceiverTwo TestReceiverThree
They each have the following function as their content:
CODE:...................
I've added each BroadcastReceiver class to the manifest, have it accept the appropriate action/category, and start debugging. I've set breakpoints in the onReceive method of each test class, and in the anonymous inner BroadcastReceiver in my onCreate.
Unfortunately, I seem to be getting somewhat undefined behavior. Sometimes getResultExtras in my second onReceive will return null. Sometimes getResultCode in the second onReceive returns 0. Sometimes I'm 1 off in my third onReceive. Sometimes I get the wrong numResults in onReceive in my activity.
Is there some other behavior I have to specify when using setResult and getResult in an ordered broadcast?

I am developing an app that upon receiving an SMS message with a unique string of text, the GPS is enabled and starts tracking the location of the phone. The issue I'm having is with the getSystemService() method.
I receive the error "The method getSystemService(String) is undefined for the type SmsReceiver", I believe this is because it does not have a context. I have tried to add in a context with in my code with 'ctx', and that removes the error but my application crashes every time I run it on my phone. The code for recieving the SMS works fine, and the GPS location tracking code works fine if it's in my main class.
I still don't fully understand contexts.
