Android :: Multiple Choice Dialog Won't Alter Array When Clicked
May 11, 2010
I have a multiplechoice dialog on my activity. I have a boolean array to keep track of which items are selected from the dialog. So I want each time an item is clicked to make the corresponding place on my array true. The array is being created in the onCreateDialog before the return.
public Dialog onCreateDialog(int id) {
userlistlocal=getuserlist(username);
boolean[] usernamechecked=new boolean[userlistlocal.length/3];
Arrays.fill(usernamechecked,false);
return new AlertDialog.Builder(Newevent.this)
.setIcon(R.drawable.ic_menu_invite)
.setTitle("Add People")..........

I have an array adapted listview (the array adapting is done in another class). I just got the click listener working for the list but now I want set it up so that when I click an item. It pulls the strings from the clicked item and piggybacks them on the intent to a new activity. I figure I am supposed to use intent.putextra however I am not sure how to pull the correct strings corresponding to the item that i click on. My code is below. I am simply lost to be honest
//Initialize the ListView lstTest = (ListView)findViewById(R.id.lstText);
//Initialize the ArrayList alrts = new ArrayList<Alerts>();
//Initialize the array adapter notice with the listitems.xml layout
arrayAdapter = new AlertsAdapter(this, R.layout.listitems,alrts);
//Set the above adapter as the adapter for the list
lstTest.setAdapter(arrayAdapter);
//Set the click listener for the list
lstTest.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView adapterView, View view, int item, long arg3) {
Intent intent = new Intent( HomePageActivity.this, PromotionActivity.class );
finish(); startActivity(intent); } } );
my alerts class..
public class Alerts {
public String cityid;
public String promoterid;
public String promoshortcontent;
public String promocontent;
public String promotitle;
public String locationid;
public String cover;
@Override public String toString() {
return "City: " +cityid+ " Promoter: " +promoterid+ "Short Promotion: " +promoshortcontent+ "Promotion: " +promocontent+ "Title: " +promotitle+ "Location: " +locationid+ "Cover: " +cover+ "$"; } }
anddddd my alertsadapter class..
public class AlertsAdapter extends ArrayAdapter<Alerts> {
int resource;
String response; Context context;
//Initialize adapter public AlertsAdapter(Context context, int resource, List<Alerts> items) {
super(context, resource, items); this.resource=resource;
} @Override public View getView(int position, View convertView, ViewGroup parent)
{ LinearLayout alertView; //Get the current alert object Alerts al = getItem(position);
//Inflate the view if(convertView==null) {
alertView = new LinearLayout(getContext());
String inflater = Context.LAYOUT_INFLATER_SERVICE; LayoutInflater vi;
vi = (LayoutInflater)getContext().getSystemService(inflater);
vi.inflate(resource, alertView, true); } else {
alertView = (LinearLayout) convertView; }
//Get the text boxes from the listitem.xml file
TextView textPromo =(TextView)alertView.findViewById(R.id.txtPromo);
TextView textPromoter =(TextView)alertView.findViewById(R.id.txtPromoter);
TextView textLocation =(TextView)alertView.findViewById(R.id.txtLocation);
//Assign the appropriate data from our alert object above
textPromo.setText(al.promocontent); textPromoter.setText(al.promoterid);
textLocation.setText(al.locationid); return alertView;
} }

I would like to intercept outgoing calls and pass them to a VOIP application. I see that the Google Voice application has a feature for displaying a question before each call is actually initiated. It provides the user with the choice:
Initiate call via Google Voice
Initiate call via standard call
I would like a way to do something similar with my application (so that not all calls have to be routed through it). At the moment, I can intercept CALL events via a BroadcastReceiver, however, these are not allowed to open dialogs (thus making it possible to display the choice).
What is the best way of achieving this goal?

I've been beating my head against the wall on this one for a minute now... did I find another bug like the list selector solid color one? When I set multichoice items for a dialog as seen below my list items have white background and white text, when I click or select an item I can see the text becomes black and the orange list selector shows as expected.... anyone know what's up?.............

I plann to create application is a real time multiplayer multiple choice game. It will have a pool of approximately 600 questions that will be randomly selected for every game. Games will start on a rolling basis, consisting of 10 players at a time who must answer 20 questions per game, for quetion and logic for game it's ready , now my main part multplayer , what i need exactly:
1. Player has to choose a room from the lobbay to enter a game.
2. The player waits until thier selected room reaches 10 people. at that point, the game will start.
3. within the game, each player's score update it in real game.
4. you can click name of player to take you to that player's stats page.
i need this in android but i don't now how i can stat and what the tool i need for it , as i menstion up the logic for application ready but i need multplayer part.

I have tried to make a series of dialogs, like a questionnaire, that the user needs to answers a series of questions selecting one or more checkboxes. I can do one, just fine, but when I try to make more than one question (lets say 10), it does not show, or show all the dialogs. I tried using dialogs or new acitivities.
So, my problem is I have multiple questions, one to be presented each time, and I need to wait for one to be responded so I can ask the next one. How do I accomplish this?
My first attempt was with a dialog box... but obviously it got all the boxes stacked in each other:

I've seen example com.example.android.apis.view.List11 from ApiDemos. In that example, each row takes the view android.R.simple_list_item_multiple_choice. Each such view has a TextView and a CheckBox.
Now I want each view to have 2 TextView's and 1 CheckBox, somewhat similar to the List3 example. I tried creating a custom layout file row.xml like this:
CODE:...............
Then in Activity.onCreate(), I do like this:
CODE:..................
The result kind of looks like what I want, but it looks like the list doesn't know which item of it is selected. Also, I need to click exactly on the checkbox. In the List11 example, I only need to click on the item row.
So what do I need to do to make a multiple choice list with my custom view for each row?

I'm new to Android programming, and I wanted to pull list options from a column of the SQLite database for the user to select. How would I go about doing this? Like, say the database table to be read is called countries, and the columns were ID, country, and capital. How would I let the user pick from the list of capitals and have the application return the information in that row?

I have an extended dialog class that I want to show for 3 seconds then disappear.This works great the first 2 times it's called, but then it crashes my app after that.Admittedly, I'm not the best with threads and I think that's where my problem might be.As you can see from the code below (commented out section), I tried using a cancel event to kill the thread that is spawned, but that makes it crash the first time it's run. I've also tried doing all of this on the parent class' UI thread which yields the same result as this (crashes after 3 times displaying the dialog).

I have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);
where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);
The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?

I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?

I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.
Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);
That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.
CODE:................
But Like I said, I would like to just order through them one by one when a button is clicked.

I have tried to find a way to update the Android Preferences dynamically. Under the /res/xml directory I have placed a XML file with CheckBoxPreference elements. During application usage some of the preferences CheckBoxPreference elements may vary in numbers. Sometimes there may be 10 items and at other times there may be 35. I have tried to place the XML file in the /assets diectory (where read and write is possible) and then tried to replace the R.xml.<XMLFileName> in the addPreferenceFromResource(R.xml.<XMLFileName>) with the Assets file - but that won't work.
Is it in anyway possible to write to, during runtime programmatically, the XML files placed in the /res directory - and if - how do we do that? Is it possible - programmatically - to create and delete the entries in the preferences - thereby omitting the XML file?

I have an Options Menu on my Activity with an MenuItem "Start". When this MenuItem is selected I would like to alter the Menu so it contains a MenuItem "Stop". And finally when "Stop" is selected, I would like to alter back to "Start". Here is parts of my code that isn't working. I have both "Start" and "Stop" listed in mymenu.xml I should probably remove "stop" when the menu is created:
public class MyActivity extends Activity {
private boolean isStarted = false;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
menu.removeItem(R.id.stop);
inflater.inflate(R.menu.mymenu, menu);
return true;....................

setContentView(R.layout.my_list);
mDbHelper = new MyDbAdapter(this);
mDbHelper.open();
fillData();
registerForContextMenu(getListView());....................
The date is actually stored as an int in the SQLLite database, and thus it displays as an integer. Does anyone know a way to create a date from the int so it doesn't display as 1216544611 (or whatever) but as "12/11/2009 11:32"?

So i was wondering if its possible to for an application that i would write to be constantly running in the background and alter regular phone operations. For example this could be something like as soon as you receive a text from anyone you forward it automatically to another number. Is something like this at all possible? Just to be clear I don't want to solve that particular problem through some other means, just want to know if apps can accomplish that. Also if that is possible is it possible for an app that i write to alter more immediate and instant things, like an incoming call.

I am having a problem about repeating Login dialog (an AlertDialog) and progress dialog, coordinating with http thread. I suppose repetitive Login dialog (if fail, continue) handling should be common and straightforward. I guess my approach must be wrong somewhere. I already spent 2 days on this and am desperate. So please help. User starts the app, the main activity starts.Show a login dialog (generated by the main thread, i.e. from on Create. The main thread then starts a wait_thread, which will wait for http to return data and check the data and decide what to do.After user input username/password and press login, a progress dialog starts.The progress dialog starts an http_thread to talk to the server and get replies. Once done, it will notify the waiting thread.If the user type in the right username password first time, the code works fine.But it always fail for 2nd time Login, i.e. When first login fail(wrong username/ password),the wait_thread will generate 2nd Login dialog to let user repeat the login process. But after user hit the login on this 2nd Login dialog, the system always crashes.
