I need to generate an array that looks like the following:
String[] testlist = new String[] {"First Note", "Second Note", "Third Note"};
The information I need is inside a SQLite Database. I'm using the following code to access:
db = new notesDBHelper(this);
//notesDBHelper is a standard SQLiteHelper, the DB has a table called notes with fields 'title' and 'note_text'
String query = String.format("SELECT * FROM notes");
db.getReadableDatabase().rawQuery(query, null);
This is the point where I'm stuck - The query returns without error, but I'm not sure of the syntax to build the string.
Instead of a array you can use a list. Than you don't have to set a size.
ArrayList<String> list = new ArrayList<String>();
String[] array = new String[4]
int counter = 0;
String query = String.format("SELECT * FROM notes");
Cursor cursor = db.getReadableDatabase().rawQuery(query, null);
while (cursor.moveToNext()) {
String note = cursor.getString(1);
list.add(note);
if(counter < array.length){
array[counter] = note;
counter++;
}
}
Now I put both solution in the code. You have also to decide which row it is.
You should use a cursor with your query. A function like this (untested code from the top of the head) could work in your database helper class.
public ArrayList<String> getStrings() {
ArrayList<String> strings = new ArrayList<String>();
String query = String.format("SELECT * FROM notes");
Cursor c = db.getReadableDatabase().rawQuery(query, null);
if (c.moveToFirst())
do {
strings.add(sessionCursor.getString(1)); // 1 = columnindex
} while (sessionCursor.moveToNext());
return strings;
}
