如何在android中为数据库调用soap的Web服务。
我的 Web 服务在 C# 中的 ASP.NET 中。
为什么 NewDataSet 和 Table 值没有显示在 android 的soap web 服务中请回答。

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

MainActivity.this.runOnUiThread(new Runnable() {
public void run() {
output.setText(resultString);
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
};
thread.start();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
我的 Web 服务结果是：
