Android TabbedFragment中的SqliteOpenHelper获取stackOverFlow错误和TransactionTooLargeException

我正试图在Android的TabbedFragment中使用一个数据库（从SqliteOpenHelper扩展而来）。但我有一个StackOverFlow错误和一个TransactionTooLarge异常，这是我的日志：

` 这是我的片段类：

public class dataBaseFragment extends Fragment {
    private static final String TAG = "DataBaseFragment";
    private TextView tv;
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View v= inflater.inflate(R.layout.data_base_fragment,container,true);
        Database db= new Database(getActivity().getApplicationContext());
        SQLiteDatabase dbWrite= db.getWritableDatabase();
        tv= (TextView) v.findViewById(R.id.tv);
        tv.setText("Ciaoooooooo");
        Log.d(TAG, "onCreateView: ");
        ContentValues cv= new ContentValues();
        cv.put("name","pippo");
        cv.put("sex","maschio");
        dbWrite.insert("user",null,cv);
        cv= new ContentValues();
        cv.put("name","tizia");
        cv.put("sex","femmina");
        dbWrite.insert("user",null,cv);
        db.close();
        SQLiteDatabase dbRead = db.getReadableDatabase();
        Cursor cursor= dbRead.query("user",new String[]{"name","sex"},"name=?",new String[]{"pippo"},null,null,null);
        while(cursor.moveToNext())
        {
           String name= cursor.getString(cursor.getColumnIndex("name"));
            String sex =cursor.getString(cursor.getColumnIndex("sex"));
            Log.d(TAG,String.format("name=%s, sex=%s",name,sex ));
        }
        return v;
    }
}

这是我的Sqlite Openhelper类：

public class Database extends SQLiteOpenHelper {

    public Database(Context context) {
        super(context, "db", null,1);
    }

    public void onCreate(SQLiteDatabase db) {

        db.execSQL("CREATE TABLE user(" +
                "_id INTEGER PRIMARY KEY AUTOINCREMENT," +
                "name TEXT DEFAULT \"\"," +
                "sex TEXT DEFAULT \"\")");
    }
    public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {    
    }
}

如果不附加充气视图，会发生什么情况：

View v= inflater.inflate(R.layout.data_base_fragment,container,false);

---

您不应该自己将片段的视图附加到容器，尽管这可能不是唯一的问题（引发的异常将是

IllegalStateException

）

只是一个建议，在您完成工作后关闭光标。非常感谢。你的意思是什么？当调用

inflate

时，最后一个参数（

attachToRoot

）应该是

false

，否则你会得到容器（附加充气视图），而不是我用充气器尝试的充气视图。充气（R.layout.data\u base\u fragment，container，false）；它现在正在工作，我在更改后重建项目。非常感谢你。祝你圣诞快乐
