An aside - Google needs to catch up

The XML Layout: MultiAutoCompleteTextView

SetTokeniser: UsernameTokenizer

• terminateToken(CharSequence text) - this basically just provides a presentable version of our token with a proper terminator at the end (e.g. makes sure a trailing single space in this case)
• findTokenStart(CharSequence text, int cursor) - Just finds the position of the start of the token. It does this by iterating backwards through the provided CharSequence (the text input in the input box) starting from the position of the cursor, which is just the position of the last character edited (this means if you go back and edit text in the middle of a block it still finds the correct token).  If no valid token start is found (e.g. we go backwards and we can't find a @ character) then the current position is returned - no dropdown is displayed.
• findTokenEnd(CharSequence text, int cursor) - As above, but finds the end position. Iterates forward until a token terminator (in our case a space) or the end of the text is found

Does generated code always suck?

Let's get down to business, don't got no time to play around, what is this..

private static String DB_PATH = "/data/data/com.tmm.android.chuck/databases/";
private static String DB_NAME = "questionsDb";
private SQLiteDatabase myDataBase; 
private final Context myContext;

public DBHelper(Context context) {
 super(context, DB_NAME, null, 1);
 this.myContext = context;
} 

public void createDataBase() throws IOException{

 boolean dbExist = checkDataBase();
 if(!dbExist)
 {
  this.getReadableDatabase();
  try {
   copyDataBase(); 
  } catch (IOException e) {
   throw new Error("Error copying database");
  }
 }
}

private void copyDataBase() throws IOException{

 InputStream myInput = myContext.getAssets().open(DB_NAME);

 String outFileName = DB_PATH + DB_NAME;

 OutputStream myOutput = new FileOutputStream(outFileName);

 byte[] buffer = new byte[1024];
 int length;
 while ((length = myInput.read(buffer))>0){
  myOutput.write(buffer, 0, length);
 }

 //Close the streams
 myOutput.flush();
 myOutput.close();
 myInput.close();
}

public List getQuestionSet(int difficulty, int numQ){
 List questionSet = new ArrayList();

Cursor c = myDataBase.rawQuery("SELECT * FROM QUESTIONS WHERE DIFFICULTY=" + difficulty +
   " ORDER BY RANDOM() LIMIT " + numQ, null);
 
while (c.moveToNext()){
  Question q = new Question();
  q.setQuestion(c.getString(1));
  q.setAnswer(c.getString(2));
  q.setOption1(c.getString(3));
  q.setOption2(c.getString(4));
  q.setOption3(c.getString(5));
  q.setRating(difficulty);
  questionSet.add(q);
 }
 return questionSet;
}
