Question

  public List<Diagnosis_tble> GetAllPatientDetails()
     {
      List<Diagnosis_tble> DiagnosistblList = new   ArrayList<Diagnosis_tble>();  
      String selectQuery = "SELECT  * FROM " + TABLE_Diagnosistble + "";  
      SQLiteDatabase db = this.getWritableDatabase();
      Cursor cursor = null;

       {  
        cursor = db.rawQuery(selectQuery, null);

      if(cursor.getCount() > 0)
      {
        if (cursor.moveToFirst()) 

         do{     
            Diagnosis_tble  diagCreation_tble = new Diagnosis_tble(); 

             diagCreation_tble.SetDiagnosisID(cursor.getString(0));
             diagCreation_tble.SetPName(cursor.getString(1));
             diagCreation_tble.SetHospitalNo(cursor.getString(2));
             diagCreation_tble.SetPGender(cursor.getString(3));
             diagCreation_tble.SetPacemaker(cursor.getString(4));
             diagCreation_tble.SetDiagType(cursor.getString(5));
             diagCreation_tble.SetP_Age(cursor.getString(6));
             diagCreation_tble.SetDeviceID(cursor.getString(7));
             diagCreation_tble.SetDiagStrtTime(cursor.getString(8));
             diagCreation_tble.SetDiagEndTime(cursor.getString(9));
             diagCreation_tble.SetDiagStatus(cursor.getString(10));
             diagCreation_tble.SetReportStatus(cursor.getString(11));
             diagCreation_tble.SetUploadStatus(cursor.getString(12));

          DiagnosistblList.add(diagCreation_tble); 

         }while (cursor.moveToNext());

          return DiagnosistblList; 
      }else
      {
          return null;
      } 
    }
    finally
    {
        cursor.close();
    }
}

这段代码有什么问题？

我得到了这个例外：

 java.lang.RuntimeException: Unable to start activity 
 ComponentInfo{com.abc.TestApp/com.abc.TestApp.LoadData}:
 android.database.CursorWindowAllocationException: Cursor window allocation of 2048 kb failed.

我遇到了和你一样的麻烦。我做的是我遍布我的应用程序数据类并关闭所有其他未关闭的游标对象。所以我猜你的应用程序也会发生同样的情况，打开你的数据类，找到没有关闭的游标并关闭它们

Sqlite游标窗口分配2048 kb失败
