Android Sqlite Datenbank funktioniert nicht richtig

Question

Ich versuche einfach, eine Quiz-App zu erstellen, für die ich die Daten in der Datenbank speichern werde. Der folgende Code funktioniert nicht, und die App stürzt

log

public class QuestionFeedMainPage extends AppCompatActivity { 
    Button b1; 
    EditText e1,e2,e3,e4,e5; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_question_feed_main_page); 
     b1 = (Button)findViewById(R.id.submitQF); 
     e1 = (EditText)findViewById(R.id.q); 
     e2 = (EditText)findViewById(R.id.o1); 
     e3 = (EditText)findViewById(R.id.o2); 
     e4 = (EditText)findViewById(R.id.o3); 
     e5 = (EditText)findViewById(R.id.o4); 
     b1.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       String q = e1.getText().toString(); 
       String o1 = e2.getText().toString(); 
       String o2 = e3.getText().toString(); 
       String o3 = e4.getText().toString(); 
       String o4 = e5.getText().toString(); 
       if(q.equals("") || o1.equals("") || o2.equals("") || o3.equals("") || o4.equals("")){ 
        Toast.makeText(QuestionFeedMainPage.this, "Please fill all the fields", Toast.LENGTH_SHORT).show(); 
       } 
       else { 
        SQLiteDatabase sql = openOrCreateDatabase("multip",MODE_PRIVATE,null); 
        sql.execSQL("create table if not exists questions (sno INTEGER PRIMARY KEY AUTOINCREMENT,question varchar,optionone varchar,optiontwo varchar,optionthree varchar,optionfour varchar)"); 
        String s4 = "select * from questions where question='"+q+"'"; 
        Cursor cursor = sql.rawQuery(s4,null); 
        if(cursor.getCount()>0){ 
         Toast.makeText(QuestionFeedMainPage.this, "This question already exist", Toast.LENGTH_SHORT).show(); 
        } 

        else{ 
         sql.execSQL("insert into questions values ('"+q+"','"+o1+"','"+o2+"','"+o3+"','"+o4+"')"); 
         Toast.makeText(QuestionFeedMainPage.this, "Question Added", Toast.LENGTH_SHORT).show(); 
         e1.setText(""); 
         e2.setText(""); 
         e3.setText(""); 
         e4.setText(""); 
         e5.setText(""); 

        } 
       } 
      } 
     }); 
    } 
} 

Fehler jedes Mal, wenn ich die Daten füttern:

Answer 1

Die Fehlermeldung ziemlich erklärt, was los ist:

android.database.sqlite.SQLiteException: Tabelle Fragen hat 6 Spalten, aber 5 Werte wurden zur Verfügung gestellt (Code 1):, während der Kompilierung: Einfügen in Fragen Werte ('x', 'x', 'x', 'x', 'x ')

versuchen, etwas in dieser Richtung:

String sql = "INSERT INTO questions (question, optionone, optiontwo, optionthree, optionfour) VALUES (?, ?, ?, ?, ?)"; 
SQLiteStatement statement = db.compileStatement(sql); 

String q = e1.getText().toString(); 
String q1 = e2.getText().toString(); 
String q2 = e3.getText().toString(); 
String q3 = e4.getText().toString(); 
String q4 = e5.getText().toString(); 

statement.bindString(1, q); // These match to the five question marks in the sql string 
statement.bindString(2, q1); 
statement.bindString(3, q2); 
statement.bindString(4, q3); 
statement.bindString(5, q4); 

long rowId = statement.executeInsert();  

Answer 2

Sie wollen mit 6 Spalten 5 Werte in eine Tabelle füllen. Sie möchten den Primärschlüssel sno nicht einfügen.

So etwas sollte funktionieren:

sql.execSQL("insert into questions (question,optionone,optiontwo,optionthree,optionfour) values ('"+q+"','"+o1+"','"+o2+"','"+o3+"','"+o4+"')");
