android上的SQLite意外停止

我在sqlite android上。在运行项目时，我遇到了一些麻烦。 我有两件事。VivsHelper是前者，MainActivity是后者。以下是我的代码： VivzHelper类：

public class VivzHelper extends SQLiteOpenHelper {

private static final String DATABASE_NAME = "vivzdatabase";
private static final String TABLE_NAME = "VIVZTABLE";
private static final int DATABASE_VERSION = 1;
private static final String UID = "_id";
private static final String NAME = "_Name";
private Context context;
private static final String CREATE_TABLE = "CREATE TABLE" + TABLE_NAME +" ("+ UID+" INTEGER PRIMARY KEY AUTOINCREMENT, " +NAME+"_Name VARCHAR(255));";
private static final String DROP_TABLE = "DROP TABLE "+ TABLE_NAME + " IF EXISTS";
public VivzHelper(Context context){
    super(context, "", null, 1);
    this.context = context;
    // TODO Auto-generated constructor stub
}

@Override
public void onCreate(SQLiteDatabase db) {
    // TODO Auto-generated method stub
    try {
        db.execSQL(CREATE_TABLE);
        Toast.makeText(context, "Oncreate called", Toast.LENGTH_LONG).show();
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    // TODO Auto-generated method stub
    try {
        db.execSQL(DROP_TABLE);
        onCreate(db);
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

}

以下是主要活动：

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fragment_main);
    VivzHelper vivzHelper;
    vivzHelper = new VivzHelper(this);
    SQLiteDatabase sqLiteDatabase = vivzHelper.getWritableDatabase();

当我运行时，我的应用程序突然停止。为什么呢？帮帮我

这是日志目录：

是的，正如@Shifar所说，超类的参数无效，您必须传递一个数据库名称！同时检查您的Create语句，您得到了名称“+name+”_namevarchar（255））；“在它和一个分号中

请在堆栈后跟踪Hey An Thuy Dinh，我认为构造函数

super（context，”，null，1）；

应该是这样的

super（context，DATABASE_NAME，null，DATABASE_VERSION）；

谢谢你。我按照你说的方式修复了它。
