Android :: Clicking Elements Doesn't Display Correct Values / Point Where It Would Pull Old?

Apr 14, 2010

I apologize if this code looks a bit like a mess (considering the length); I figured I'd just include everything that goes on in my program at the moment.

I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value).

There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code...

Android :: Display A List With 200 Elements?

Jun 27, 2010

When I have a ListActivity and an Adapter how does Android handle a list with 200 elements.
Does it try to load all of them directly how does it wait till the user scrolls and then renders those elements?

Do I have to worry with performance when a list is too long?

Android :: Dynamic Display Of ListView Elements Partially Working

Jul 26, 2010

I am making a time sheet program where a user inputs his in- and out-punches. I have a ListView that I am populating from an array of calendar objects. I would like each row to show the day and date then on a new line the time, but I only want to display the day and date if it is different from the previous element.Currently, I am setting visibility in the Base Adapter based on comparisons using position vs position-1 (which are used as indices to the array). This only works if the whole list fits on the screen. If it extends beyond the screen and the user scrolls around the results are unpredictable.To further confuse things, I am setting the color of the times, based on the position, to alternate between green and red (in/out) and it works as expected, scrolling or not.How does Android handle the ListView position when scrolling or what could I do differently to show/hide the day and date? Code...

Android :: Images Don't Display But TextView Contents Is Correct

Oct 29, 2010

I am working on an Android application that displays a list of items when a tab is selected, then displays detail information about an item that was selected from the list :

CODE:............

The details are to be displayed using ImageViews, ImageButtons, and TextViews. The data comes from a database query, so the TextView text and ImageView drawables have to be assigned dynamically.

The correct text from the database query gets assigned to each of the Views. I can see everything being added when I step through the code in the onCreate method of Activity3 in the debugger.

BUT, the drawables are only displayed when I select the first item in the ListActivity. If I select another item, all TextViews display the correct information but the drawables are not displayed for the ImageViews or ImageButtons. It looks like only the backgrounds are being displayed.

The ImageButton drawables are not being dynamically assigned, only the ImageView drawables are. The ImageButton drawables are set in the TableLayout XML that is associated with the activity. Here is one entry :

CODE:..............

Originally, I had android_drawable="@drawable/ic_phone", then tried adding android:background="@drawable/ic_phone", and finally created the following selector (phoneselector.xml) :

If I select the first item again, its proper ImageView drawables are displayed along with the proper text in the TextViews. The ImageView drawables that belong to the other items have no problems being displayed in Activity2's ListView.

The code successfully sets an onClickListener for the button (also in Activity3.onCreate). If I click on what is displayed on the spot where the drawable should be, the phone number is dialed.

The code successfully sets an onClickListener for the button (also in DetailActivity.onCreate).

Has anyone seen anything like this before? I would appreciate any help figuring out what is wrong.

Here are more details because I wonder if the problem has to do with the use of the Views :

The Activity1 extends TabActivity and sets a TabHost view that contains a FrameLayout along with the TabWidget. Activity1 creates the tabs dynamically.

Activity2 extends ListActivity and sets the content to its ListView (via setContentView(getListView()).

When ListActivity.onListItemClick is invoked (item in list is selected), a new Intent is created that contains an identifier in a Bundle and Activity3 is started.

The started activity (in Activity3.onCreate...) sets the content to a TableLayout view defined in a .xml file (via setContentView(R.layout.details.xml).

Here is the code from Activity3.onCreate :

Android :: Correct Approach To Display Search Results On Screen

Dec 16, 2009

I want to display search result on the screen, I have implemented in such a way that. From the search form user fill the 'search field' and 'search location' I set values into bean and that bean is static so that I can access it from every where. Then I start search result screen intent using:
Intent mainIntent = new Intent(SearchVenueResults.this, SearchResults.class);
startActivity(mainIntent);

On the 'SearchResults' activity 'oncreate' method I load data on the behalf of static bean which values filled from search form and then display data.
@Override
public void onCreate(Bundle savedInstanceState) { loadDataAndSetupUI();
super.onCreate(savedInstanceState);
}
My question is is it the correct approach to use it or in Android there is another preferable approach?

Android :: HttpURLConnection Doesn't Send Correct User-Agent Header

Sep 15, 2009

I have a server that uses User Agent header to identify the device that is connecting to it. But when i connect to the server using HttpURLConnection i get no User Agent header, but when i connect with the browser it sends the correct User Agent.

For testing i am using an echo server that replies with the headers it found on the request.

When i connect with browser i get: eg: User-Agent: Mozilla/5.0 (Linux; U; Android 1.5; en-fr; HTC Hero Build/CUPCAKE) AppleWebKit/528.5+ (KHTML, like Gecko) Version/3.1.2 Mobile Safari/525.20.1 Up.Link/6.3.1.20.06.3.1.20.0.

But when i connect by code with UrlConnection i get: User-Agent: UNAVAILABLE.

Does anyone know we i get different behaviors? How i can i connect in the same way the browser does?

What i really need is not only the User-Agent header, i also need some special headers (x-up-subno actually). This header is added by the APN of the operator, but for some reason when i connect by code that headers are not added to the request.

From browser:

Android :: WebView With Theme Doesn't Show Focused Text Field Values

Apr 4, 2009

I have encountered a problem with focused text fields in a WebView not showing entered text values.As long as a WebView text field has focus it will not show text or even the blinking cursor.You can select and highlight the text or unfocus the field to see it, but when it gains focus it will not show the text as if the foreground color of the text is white.The simplest code to demonstrate this is below.With the setTheme using a Light background, try typing values into the Email text field to notice that the text is not visible when the field is focused.

Android :: How Can I Get Correct Display Metrics From Widget In Android?

Apr 15, 2010

I need to determine the screen density at runtime in an Android App Widget. I've set up an HDPI emulator device (avd). If set up a regular executable project, and insert this code into the on Create method: Similarly, if I get a resource at runtime using the Resources object obtained from context.get Resources() in the App Widget, it returns the wrong resource based on screen density. For instance, I have a 60x60px drawable for mdpi, and an 80x80 drawable for hdpi. If I get this Drawable object using context.get Resources().getDrawable(...), it returns the 60x60 version. Is there any way to correctly deal with resources at runtime from the context of an App Widget?

Android :: Setting Values And Display Text In Android Spinner

May 31, 2010

I need help in setting up value and display text in spinner. As per now I am populating my spinner by array adapter e.g. mySpinner.setAdapter(myAdapter);

And as far as I know after doing this the display text and the value of spinner at same position is same. The other attribute that I can get from spinner is the position on the item. Now in my case I want to make spinner like the drop down box, which we have in .NET. Which holds a text and value. Where as text is displayed and value is at back end. So if I change drop down box , I can either use its selected text or value. But its not happening in android spinner case.

For Example:

Text Value
Cat 10
Mountain 5
Stone 9
Fish 14
River 13
Loin 17

So from above array I am only displaying non-living objects text, and what I want is that when user select them I get there value i.e. like when Mountain selected I get 5. I hope this example made my question a bit more clear.

Android :: Droid Notification Activity Doesn't Display Occasionally / Can I Fix It

Oct 6, 2010

I have an android background Service that will occasionally post a notification to the Status Bar using the Notification class. Occasionally, when I receive a notification, pull-down the notification window, and select the notification from the list, the specified Activity doesn't start. When this happens, the screen dims (as if it were about to display the Activity), but the Activity is never shown. I included my code below...

NOTE: The UserNotification class extends Activity, and is set to a dialog theme in the manifest. This class also has its taskAffinity property set to "" in the manifest.

Android :: MapView Doesn't Display Tiles - Debugging Strategies / What's Actual Problem?

Jul 10, 2010

There are a number of posts (both here & elsewhere) about why a MapView might not be displaying tile info (personally, I've liked http://stackoverflow.com/questions/1809507/android-hello-mapview-tutorial-map-tiles-do-not-load, but there are other good ones, too).

My question is slightly different: I'm not getting tile info to show up (on my handset or in the emulator), and I'm looking for advice on what to try in order to debug this problem. As far as I can tell I've correctly located my debug.keystore, and used the Java JDK keytool to get the signature from it, which I then plugged into the Google web page, and then plugged THAT key back into my XML file. The app runs ok, it just doesn't display any tiles.

I was hoping that if I did something wrong here I'd see an error message in, say, logcat (or an exception that Eclipse might catch) that would confirm that this is the source of the error.

So here's my question - what would y'all recommend someone try in order to figure out what the actual problem is?
