Question

我无法理解这个错误，在我的更新命令中，我有10个要更新的字段，但出现此错误09-17 17:18:25.234: E/AndroidRuntime(4929): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.jpos/com.sys.Main}: java.lang.IllegalArgumentException: the bind value at index 11 is null

它表示索引11为空，但是我的表中的字段总数为10。

这是我的更新命令

 private void UpdateTableMunicipalityCodes() {
        HashMap<String, String> queryValues =  new  HashMap<String, String>();

        queryValues.put("munc_id", "7");
        queryValues.put("rdo_code", "999" );
        queryValues.put("munc_code", "999");
        queryValues.put("munc_desc", "UPDATECOMMAND");
        queryValues.put("area_code", "999");
        queryValues.put("created_date", "2013-17-2013 06:02:29");
        queryValues.put("created_by", "SYSGENn");
        queryValues.put("last_modified_date", "2013-17-2013 07:02:09");
        queryValues.put("last_modified_by", "SYSGENn");
        queryValues.put("munc_status", "A");
        hashDbHelper.updateTableMunicipality(queryValues);

      }

通过这里：

public void updateTableMunicipality(HashMap<String, String> queryValues) 
{ 
        database = this.getWritableDatabase();  
        ContentValues values = new ContentValues();
        values.put("MUNC_ID", queryValues.get("munc_id"));
        values.put("RDO_CODE", queryValues.get("rdo_code"));
        values.put("MUNC_CODE", queryValues.get("munc_code"));
        values.put("MUNC_DESC", queryValues.get("munc_desc"));
        values.put("AREA_CODE", queryValues.get("area_code"));
        values.put("CREATED_DATE", queryValues.get("created_date"));
        values.put("CREATED_BY", queryValues.get("created_by"));
        values.put("LAST_MODIFIED_DATE", queryValues.get("last_modified_date"));
        values.put("LAST_MODIFIED_BY", queryValues.get("last_modified_by"));
        values.put("MUNC_STATUS", queryValues.get("munc_status"));      
        database.update("tbl_municipality_codes", values, "MUNC_ID" + " = ?",     newString[] { queryValues.get("MUNC_ID") });
        System.out.println("Updated " + queryValues.get("munc_id"));        
      }

这是我的创建表查询

    query ="CREATE TABLE [tbl_municipality_codes] (" +
              "[MUNC_ID] [INT(1000)] NOT NULL," +
              "[RDO_CODE] [VARCHAR(50)] NOT NULL," +
              "[MUNC_CODE] [VARCHAR(50)] NOT NULL, " +
              "[MUNC_DESC] [VARCHAR(100)] NOT NULL, "+
              "[AREA_CODE] VARCHAR, "+
              "[CREATED_DATE] DATETIME NOT NULL," +
              "[CREATED_BY] [VARCHAR(50)] NOT NULL, "+
             "[LAST_MODIFIED_DATE] DATETIME," +
              "[LAST_MODIFIED_BY] [VARCHAR(50)],"+
              "[MUNC_STATUS] [VARCHAR(1)] NOT NULL,"+
              "CONSTRAINT [sqlite_autoindex_tbl_municipality_codes_1] PRIMARY KEY ([MUNC_ID]))";

我认为我的错误是在我的表中的约束自动索引器中..我该如何修复它？

您正试图阅读HashMap中不存在的条目，因此您获得了null：

queryValues.put("munc_id", "7");
...
database.update(..., newString[] { queryValues.get("MUNC_ID") });

正如muratgu所说，你必须使用queryValues.get("munc_id")。
