Question

我已经搜索了一段时间但尚未找到解决方案。我发送一个httppost到我的php文件，然后将其存储在我的mysql数据库中。但当我检查数据库时，我看到空帖。我看到它插入了条目，但值为空。我检查了我的PHP代码，如果我手动ping它的URL与它把它放入数据库的信息。我的logcat没有显示错误。

public class Add extends Activity implements View.OnClickListener
{
/** Called when the activity is first created. */
private Button add_btn;
EditText name;
EditText addy;
EditText hours;
EditText desc;
TextView error;

  @Override
