Java 控件在使用DropboxSyncAPI Android时不会进入onActivityResult方法中的if条件

我已经遵循了网站教程中的基本步骤，但是，我似乎无法链接我的帐户，它一直失败。我在屏幕上放了一个TextView，当它输入代码的某些部分时，我会更改它

当我运行应用程序时会发生什么：当应用程序打开时，它会要求我登录到dropbox帐户，当我允许应用程序权限时，它会返回到应用程序中，文本视图上显示的文本是：我没有批准此操作

主要活动：

public class MainActivity extends ActionBarActivity {

    private DbxAccountManager mDbxAcctMgr;

    TextView checking;

    static final int REQUEST_LINK_TO_DBX = 0;

                }

            } else {

                checking.setText("I did not approve this");
                // ... Link failed or was cancelled by the user.
            }
        } else {

更新： 我在onActivityResult方法中添加了更多日志。

---

此外，当我第二次运行应用程序时，这种情况就开始发生了，在此之前，应用程序运行良好：TextView甚至显示了connection successful

我有点困惑。您问题的标题说控件不会进入onActivityResult方法，但您报告的消息“我没有批准”只设置在onActivityResult中，对吗？因此，看起来控件肯定会进入ActivityResult，但由于某些原因，resultCode不是Activity.RESULT\u OK。对吗？@smarx对不起，我就是这个意思！我会马上编辑这个问题。你能在每个代码路径中添加一些日志记录并发布新的输出吗？这样我们就可以准确地看到什么是在什么时候执行的，执行了多少次，等等。？例如，向onActivityResult的每个部分添加日志记录。注销resultCode的值也可能很好。再次您好@Greg我已经添加了日志。我认为这是因为应用程序已经在线授权一次：这可能是日志的原因：03-21 00:03:50.849 18691-18691/com.ashwinpraveen.driveapp.dropboxsyncapi W/com.dropbox.sync.android.CoreAccountManager﹕ 用户ID 390717823的重复链接，取消新帐户的链接。我不知道如何解决它，即使它是问题。谢谢，这有助于澄清发生了什么。看起来问题只是你再次链接了同一个帐户，所以你得到了结果代码，因为没有什么真正的改变。如果您只是想继续使用同一个帐户，那么没有理由再次调用startLink。如果你链接了一个不同的帐户，你会得到结果。
