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'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 have two Activities that need to insert data into the same sqlite database. When the second Activity calls SQLiteOpenHelper.getWriteableDatabase() an IllegalStateException is thrown with the message "SQLiteDatabase created and never closed".
I've been able to avoid the Exception by making my database object a singleton but I'm thinking there must be a better way.
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.

View 2 Replies View RelatedI 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?

View 3 Replies View RelatedI put my database field in "assets" folder. And use the code from this blog to copy the database to "/data/data/my_packname/databases/", (This copy code i run it in the onCreate() method when i run this app) then use select * from ... to get data. But it gives me the exception: no such table. Someone told me that if i am attempting to copy the file in SQLiteOpenHelper's onCreate(), it's too late. So the copy file code can not copy the complete file. So i need to use adb or ddms to pull the database first? So, Anyone can teach me how to use my own databse?

public void delete(String id, String name, String phonenumber, String time, String message)
{
String[] args={id};
getWritableDatabase().delete("texts", "_ID=?", args);
}
It works fine, and deletes the specified row. However, I also want to implement it so that I can delete the most recent (earliest date) entry in the database, which should be at the top of the table. I know I can do this by altering the last 2 parameters of delete, but I cannot figure out what to change them to.

View 6 Replies View RelatedIs it really necessary to close an SQLite database that your activity has opened (database is in local memory or on SD card)? I would think it would be good practice, but I noticed that the Android samples such as the Notepad tutorial and SearchableDictionary sample do not do this. I've also seen sample code where the database is consistently opened, read from, and closed, but that would seem to add unnecessary overhead.
