应用程序在db.execsql（）上取消cecloses;

Question

当我尝试查看持有数据库持有人的类时，我的应用程序会不断拒绝。我在数据库的onCreate（）方法上遇到了一个错误。我有一个应用程序，它使用相同的数据库写入几乎与唯一的区别是我试图单击菜单选项而不是常规按钮，我不知道这是否会影响该问题。如果有人能告诉我怎么了，那会很好。谢谢你。

数据库类中的ongreate方法

@Override
    public void onCreate(SQLiteDatabase db) {
        // TODO Auto-generated method stub
        db.execSQL(" CREATE TABLE " + DATABASE_TABLE + " (" +
        KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
        KEY_LATITUDE + " TEXT IS NOT NULL, " +
        KEY_LONGITUDE + " TEXT IS NOT NULL, " +
        KEY_TIME + " TEXT IS NOT NULL, " +
        KEY_DATE + " TEXT IS NOT NULL);");


    }

观众类

public class DatabaseViewer extends Activity{

private TextView dbla;
private TextView dblo;
private TextView dbti;
private TextView dbda;

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.database);


    dbln = (TextView) findViewById(R.id.dblo);
    dbti = (TextView) findViewById(R.id.dbti);
    dbda = (TextView) findViewById(R.id.dbda);

    dbla = (TextView) findViewById(R.id.dbla);
    Database info = new Database(this);
    info.open();
    String data = info.latData();
    info.close();
    dblt.setText(data);
}

 }

Answer 1

尝试这个：

1）删除“是”

2）删除';'在最后

Answer 2

从 一些SQLITE文档：

每个表的一组SQL约束。 SQLITE支持独特的，而不是零检查和外键约束。

取出“ IS”的“不是not null”的部分来读取“文本而不是null”

Answer 3

问题是表格创建查询。

删除“ is” ..这就是logcat所说的

做一件事..使用sqlite管理器使用firefox。
