How do I save the contents of an array to a file and then read it again later? I have a small amount of data that will need to be stored and since I have no idea where to start on using a SQLite database, I think this will work a lot better.

View 1 Replies View RelatedI'm creating an Android app, where the user starts out seeing a list of questions. When the user clicks a question, I would like to show him a new clickable list, containing that question and its answer alternatives.
My questions reside in rows in the database. The questions live in the first column, while the answer alternatives live in the following columns.
I've managed to display any single element from the row when I click a question in the list, but how to display more than one completely eludes me.
This is the relevant source code in the intent entered when the user clicks a question:
private void fillData() {
Bundle extras = getIntent().getExtras();
Long id = extras != null ? extras.getLong(QuestionsDbAdapter.KEY_ROWID) : null;
Cursor questionsCursor = mDbHelper.fetchQuestion(id);
startManagingCursor(questionsCursor);
String[] from = new String[]{mDbHelper.KEY_QUESTION,
mDbHelper.KEY_ALT1,mDbHelper.KEY_ALT2};
int[] to = new int[]{R.id.text1};
SimpleCursorAdapter questions =
new SimpleCursorAdapter(this, R.layout.questions_one_row,
questionsCursor, from,to);
setListAdapter(questions);}
This displays only the question. If I put one of the answer alternatives first in the 'String[] from ...' statement, that gets displayed instead.

View 2 Replies View RelatedI've read the answer to a question as to how to access the contents of the databases, however I cannot seem to get it to work on my machine. Here is the shell log:
C:android-sdk-windows ools>adb -s emulator-5554 shell
# sqlite3 /data/data/com.android.demo.notepad2/databases/notes
sqlite3 /data/data/com.android.demo.notepad2/databases/notes
SQLite version 3.5.9
Enter ".help" for instructions
sqlite> .tables
.tables
sqlite> ^C
C:android-sdk-windows ools>
SQLite simply echos my commands back to me, even although the Eclipse file browser tells me it exists. If I use the sqlite3 tool and use ".tables" the commands are accepted.
Is the SQLite syntax different through the emulator is am I missing something?
Is there a simple way to change the contents of a dialog box in Android without having to re-create the dialog box? I know that Activity.onCreateDialog() is only called once when the dialog first needs to be created, and this is where you initially set the dialog's contents. I need to change the dialog's contents later, so I'm wondering what is the proper way to do this.

View 5 Replies View RelatedI have been trying out new ROM's and it's been fun. Here is my biggest headache with doing this. I have about 10 contacts that are Direct Dial (speed dial to the rest of the world). What I do is put them in a folder as a shortcut to prevent accidental dialing. But I have to constantly redo this set up. Is there a way to save a folder and it's contents, such as direct dial numbers, to my sd card and bring it back with each new ROM or launcher? Starred folder doesn't work for me as it's more clicking when I am driving. The app Direct Dial still takes several clicks.
