未能读取第 0 行第 3730 列

Question

这是我的代码：

dbAdapterdepartamento = new DBAdapterDepartamento(new Sqlitebbdd(
                getApplicationContext()));

        Cursor cdept=dbAdapterdepartamento.getAllDepartamentos();
        cdept.moveToFirst();


        while (cdept.isAfterLast() == false) {
          if (cdept.getFloat(cdept.getColumnIndex("_id")) == 0) {
              String title = cdept.getString(cdept.getColumnIndex("departamento"));
              Log.e("",""+title);
          }       
          cdept.moveToNext();
        }
        cdept.moveToNext();


        departamentoSpinnerAdapter = new SimpleCursorAdapter(this,
                android.R.layout.simple_spinner_dropdown_item,
                cdept,
                new String[] { Tablas.ColumnDEPARTAMENTO.NOMBRE_DEPARTAMENTO },
                new int[] { android.R.id.text1 },
                SimpleCursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);

        sp2 = (Spinner) findViewById(R.id.spinner2);
        sp2.setAdapter(departamentoSpinnerAdapter);
        sp2.setOnItemSelectedListener(this);

游标只有28行2列，但每次都return很多列。这是错误：

Failed to read row 0, column 3730 from a CursorWindow which was 28 rows, 2 columns.

Answer 1

我认为你的数据库在

      String title = cdept.getString(cdept.getColumnIndex("departamento"));

为了

row 0 , column departamento

保留编号 3730，实际上您的数据库 table 结构没有索引为 3730 的列

所以您在 table 值中有错误值的问题，可能是插入问题
