我正在尝试获取 中元素的计数，这样我就可以循环获取列表，但我尝试过的方法似乎不起作用。

下面是我使用的代码

private void processRetrievedDatabase(SoapObject soapResult)
    {
        int i = 0;
        int j = 0;
        SoapObject rootArray = ((SoapObject)soapResult.getProperty(0));
        SoapObject dbArray = ((SoapObject)rootArray.getProperty(0));
        int dbCount = dbArray.getPropertyCount();
        ArrayList<String> databases = new ArrayList<String>();
        while (i < dbCount)
        {
            if (i % 2 == 0)
            {
                databases.add(dbArray.getPropertyAsString(i));
                Log.d(TAG, dbArray.getPropertyAsString(i));
            }
            else
            {
                SoapObject tablesArray = ((SoapObject)dbArray.getProperty(i));
                int tableCount = tablesArray.getPropertyCount();
                while (j < tableCount)
                {
                    Log.d(TAG, tablesArray.getPropertyAsString(j));
                    j++;
                }
            }
            i++;
        }

下面是我在 logcat 中得到的内容

12-04 19:52:49.480: D/Soap Manager(6204): anyType{Key=information_schema; Value=anyType{string=CHARACTER_SETS; string=COLLATIONS; string=COLLATION_CHARACTER_SET_APPLICABILITY; string=COLUMNS; string=COLUMN_PRIVILEGES; string=ENGINES; string=EVENTS; string=FILES; string=GLOBAL_STATUS; string=GLOBAL_VARIABLES; string=KEY_COLUMN_USAGE; string=PARAMETERS; string=PARTITIONS; string=PLUGINS; string=PROCESSLIST; string=PROFILING; string=REFERENTIAL_CONSTRAINTS; string=ROUTINES; string=SCHEMATA; string=SCHEMA_PRIVILEGES; string=SESSION_STATUS; string=SESSION_VARIABLES; string=STATISTICS; string=TABLES; string=TABLESPACES; string=TABLE_CONSTRAINTS; string=TABLE_PRIVILEGES; string=TRIGGERS; string=USER_PRIVILEGES; string=VIEWS; string=INNODB_BUFFER_PAGE; string=INNODB_TRX; string=INNODB_BUFFER_POOL_STATS; string=INNODB_LOCK_WAITS; string=INNODB_CMPMEM; string=INNODB_CMP; string=INNODB_LOCKS; string=INNODB_CMPMEM_RESET; string=INNODB_CMP_RESET; string=INNODB_BUFFER_PAGE_LRU; }; }
12-04 19:53:01.896: D/Soap Manager(6204): anyType{Key=information_schema; Value=anyType{string=CHARACTER_SETS; string=COLLATIONS; string=COLLATION_CHARACTER_SET_APPLICABILITY; string=COLUMNS; string=COLUMN_PRIVILEGES; string=ENGINES; string=EVENTS; string=FILES; string=GLOBAL_STATUS; string=GLOBAL_VARIABLES; string=KEY_COLUMN_USAGE; string=PARAMETERS; string=PARTITIONS; string=PLUGINS; string=PROCESSLIST; string=PROFILING; string=REFERENTIAL_CONSTRAINTS; string=ROUTINES; string=SCHEMATA; string=SCHEMA_PRIVILEGES; string=SESSION_STATUS; string=SESSION_VARIABLES; string=STATISTICS; string=TABLES; string=TABLESPACES; string=TABLE_CONSTRAINTS; string=TABLE_PRIVILEGES; string=TRIGGERS; string=USER_PRIVILEGES; string=VIEWS; string=INNODB_BUFFER_PAGE; string=INNODB_TRX; string=INNODB_BUFFER_POOL_STATS; string=INNODB_LOCK_WAITS; string=INNODB_CMPMEM; string=INNODB_CMP; string=INNODB_LOCKS; string=INNODB_CMPMEM_RESET; string=INNODB_CMP_RESET; string=INNODB_BUFFER_PAGE_LRU; }; }

我几乎已经完成了，但它应该打印出数据库，然后是 log cat 中的所有表并重复，但由于某种原因它只打印第一个数据库及其表。

所以在我上面的例子中，它应该打印

information_schema
CHARACTER_SETS
COLLATIONS
COLLATION_CHARACTER_SET_APPLICABILITY
etc
etc
boardies_password_manager
alarms
categories
passwords
etc
etc

但我只得到 information_schema 及其表而不是数据库的其余部分

感谢您提供的任何帮助。

Answer 1

如果我理解正确的话，它只打印第一个数据库，因为在为下一个表开始循环之前，j 变量没有重置为 0。所以，else block 应该是这样的:

  else
       {
            SoapObject tablesArray = ((SoapObject)dbArray.getProperty(i));
            int tableCount = tablesArray.getPropertyCount();

            // j should reset to 0
            j = 0;
            while (j < tableCount)
            {
                Log.d(TAG, tablesArray.getPropertyAsString(j));
                j++;
            }
        }

或者您可能需要这样的 for 循环(我喜欢这种方式，因为它比 while 更简单、更清晰):

private void processRetrievedDatabase(SoapObject soapResult)
{
    SoapObject rootArray = ((SoapObject)soapResult.getProperty(0));
    SoapObject dbArray = ((SoapObject)rootArray.getProperty(0));
    int dbCount = dbArray.getPropertyCount();
    ArrayList<String> databases = new ArrayList<String>();
    for(int i = 0; i < dbCount; i++){
        if (i % 2 == 0)
        {
            databases.add(dbArray.getPropertyAsString(i));
            Log.d(TAG, dbArray.getPropertyAsString(i));
        }
        else
        {
            SoapObject tablesArray = ((SoapObject)dbArray.getProperty(i));
            int tableCount = tablesArray.getPropertyCount();
            for(int j = 0; j < tableCount; j++){
                Log.d(TAG, tablesArray.getPropertyAsString(j));
            }
        }
    }
}
