SQLite keine Werte einfügen

Question

Ich weiß nicht, warum, aber wenn ich in in meiner app log es nicht die Werte in der SQLite-Datenbank erstellen

dies ist mein Code:

public class SQLiteHandler extends SQLiteOpenHelper { 

    private static final String TAG = SQLiteHandler.class.getSimpleName(); 

    // All Static variables 
    // Database Version 
    private static final int DATABASE_VERSION = 1; 

    // Database Name 
    private static final String DATABASE_NAME = "android_api"; 

    // Login table name 
    private static final String TABLE_USERS = "users"; 

    // Login Table Columns names 
    private static final String KEY_ID = "id"; 
    private static final String KEY_NAME = "nome"; 
    private static final String KEY_EMAIL = "email"; 
    private static final String KEY_UID = "uid"; 
    private static final String KEY_DATA_NASCIMENTO = "data_nascimento"; 
    private static final String KEY_DATA_CRIADO = "user_datacriado"; 

    public SQLiteHandler(Context context) { 
     super(context, DATABASE_NAME, null, DATABASE_VERSION); 
    } 

    // Creating Tables 
    @Override 
    public void onCreate(SQLiteDatabase db) { 
     String CREATE_LOGIN_TABLE = "CREATE TABLE " + TABLE_USERS + "(" 
       + KEY_ID + " INTEGER PRIMARY KEY," + KEY_NAME + " TEXT," 
       + KEY_EMAIL + " TEXT UNIQUE," + KEY_UID + " TEXT," 
       + KEY_DATA_CRIADO + " TEXT" + ")"; 
     db.execSQL(CREATE_LOGIN_TABLE); 

     Log.d(TAG, "Database tables created"); 
    } 

    // Upgrading database 
    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // Drop older table if existed 
     db.execSQL("DROP TABLE IF EXISTS " + TABLE_USERS); 

     // Create tables again 
     onCreate(db); 
    } 

    /** 
    * Storing user details in database 
    * */ 
    public void addUser(String nome, String email, String uid, String data_nascimento, String user_datacriado) { 
     SQLiteDatabase db = this.getWritableDatabase(); 

     ContentValues values = new ContentValues(); 
     values.put(KEY_NAME, nome); // Name 
     values.put(KEY_EMAIL, email); // Email 
     values.put(KEY_UID, uid); // Email 
     values.put(KEY_DATA_NASCIMENTO, data_nascimento); // Created At 
     values.put(KEY_DATA_CRIADO, user_datacriado); // Created At 

     // Inserting Row 
     long id = db.insert(TABLE_USERS, null, values); 
     db.close(); // Closing database connection 

     Log.d(TAG, "New user inserted into sqlite: " + id); 
    } 

    /** 
    * Getting user data from database 
    * */ 
    public HashMap<String, String> getUserDetails() { 
     HashMap<String, String> user = new HashMap<String, String>(); 
     String selectQuery = "SELECT * FROM " + TABLE_USERS; 

     SQLiteDatabase db = this.getReadableDatabase(); 
     Cursor cursor = db.rawQuery(selectQuery, null); 
     // Move to first row 
     cursor.moveToFirst(); 
     if (cursor.getCount() > 0) { 
      user.put("nome", cursor.getString(1)); 
      user.put("email", cursor.getString(2)); 
      user.put("uid", cursor.getString(3)); 
      user.put("created_at", cursor.getString(4)); 
     } 
     cursor.close(); 
     db.close(); 
     // return user 
     Log.d(TAG, "Fetching user from Sqlite: " + user.toString()); 

     return user; 
    } 

    /** 
    * Re crate database Delete all tables and create them again 
    * */ 
    public void deleteUsers() { 
     SQLiteDatabase db = this.getWritableDatabase(); 
     // Delete All Rows 
     db.delete(TABLE_USERS, null, null); 
     db.close(); 

     Log.d(TAG, "Deleted all user info from sqlite"); 
    } 
} 

Dies ist in dem Login-Fragmente:

@Override 
      public void onResponse(String response) { 
       Log.d(TAG, "Login Response: " + response.toString()); 
       hideDialog(); 

       try { 
        JSONObject jObj = new JSONObject(response); 
        boolean error = jObj.getBoolean("error"); 

        // Check for error node in json 
        if (!error) { 
         // user successfully logged in 
         // Create login session 
         session.setLogin(true); 

         // Now store the user in SQLite 
         String uid = jObj.getString("uid"); 

         JSONObject user = jObj.getJSONObject("user"); 
         String name = user.getString("nome"); 
         String email = user.getString("email"); 
         String data_nascimento = user.getString("data_nascimento"); 
         String user_datacriado = user.getString("user_datacriado"); 

         // Inserting row in users table 
         db.addUser(name, email, uid, data_nascimento, user_datacriado); 
         // Launch main activity 
         //Intent intent = new Intent(LoginActivity.this, 
           //MainActivity.class); 
         //startActivity(intent); 
         //finish(); 

         // Launch login activity 
         Intent intent = new Intent(
           getActivity(), 
           MainActivity.class); 
         startActivity(intent); 
        } else { 
         // Error in login. Get the error message 
         String errorMsg = jObj.getString("error_msg"); 
         Toast.makeText(getContext(), 
           errorMsg, Toast.LENGTH_LONG).show(); 
        } 
       } catch (JSONException e) { 
        // JSON error 
        e.printStackTrace(); 
        Toast.makeText(getContext(), "Json error: " + e.getMessage(), Toast.LENGTH_LONG).show(); 
       } 

      } 
     }, new Response.ErrorListener() { 
... 

Während des Debuggen, die adduser(...) Methode:

long id = db.insert(TABLE_USERS, null, values); 

id ist immer -1 und ich weiß nicht warum.

Answer 1

Ein Problem ist, dass Ihre CREATE TABLE die SQL für die data_nascimento Spalte fehlt, in die Sie Werte einfügen möchten.

Nach dem Hinzufügen können Sie Ihre App deinstallieren, um die Datenbank neu zu erstellen.

Answer 2

Versuchen Sie, Autoincrement zu IdPRIMARY KEY Spalte hinzuzufügen.
