my database contains questions and each question has three options. everything work fine but when I try to get the questions and options randomly it it gives me errors:
I found similar questions to my problem but it also didn't work,
here is my code:
public List<Test> getTest() {
List<Test> MyList = new ArrayList<Test>();
myDB=this.getReadableDatabase();
Cursor cursor = myDB.rawQuery("SELECT * FROM " + My_Table + "ORDER BY RANDOM() LIMIT 1", null);
if (cursor.moveToFirst()) {
do {
Test newQ = new Test();
newQ .setId(cursor.getInt(0));
newQ .setTest(cursor.getString(1));
newQ .setAns(cursor.getString(2));
newQ .setO1(cursor.getString(3));
newQ .setO2(cursor.getString(4));
newQ .setO3(cursor.getString(5));
MyList .add(newQ );
} while (cursor.moveToNext());
}
return MyList ;}
when I add this line to my code:
ORDER BY RANDOM() LIMIT 1
the activity will not work.
