如何在rawquery中使用字符串？

Question

我創建於Android studio.I應用程序首先使用getQuestion光標隨機得到一個問題，其中id = 0（將別人改變這一點的東西）

SQLiteDatabase myDatabase = this.openOrCreateDatabase("Questions", MODE_PRIVATE, null); 
Cursor getQuestion = myDatabase.rawQuery("SELECT question FROM questions WHERE id = '0' ORDER BY RANDOM() LIMIT 1",null); 
int questionIndex = getQuestion.getColumnIndex("question"); 

在同一個桌子上有答案列。我想獲得我隨機getQuestion查詢中使用這樣的事情

Cursor getAnswer = myDatabase.rawQuery("SELECT answer FROM questions WHERE question = ?"); 

我無法找到如何使用的問題作爲一個字符串，並在的getAnswer query.What使用它，我應該得到了問題的答案做什麼？

int questionIndex = getQuestion.getColumnIndexOrThrow("question"); 
int answerIndex = getQuestion.getColumnIndexOrThrow("answer"); 
...
