如何将更新后的 phone 号码放入我为 Android 应用程序选择的字段中？

Question

如何将更新后的 phone 号码放入我选择的字段中？我让选择器返回 phone 号码，但在错误的字段中。

选择联系人后，phone 号码被放置在错误的字段中。

负责此联系人选择器逻辑的片段在我的存储库中 https://github.com/jackygrahamez/MayDay/blob/gradle2/app/src/main/java/com/mayday/md/common/ContactPickerFragment.java

我如何重构此代码以将数字放入正确的字段中？

您当前的设置有 WizardActivity 作为父片段 activity，SetupContactsFragment 作为片段，ContactPickerFragment 作为子片段。当 ContactPickerFragment 发出 startActivityForResult(...) 调用时，onActivityResult(...) 回调在 WizardActivity 中收到。

问题：

首先，WizardActivity's 成员变量 contactPickerFragment 从未被使用过。它不属于您的 ui。因此，在 WizardActivity#onActivityResult(...) 中调用 contactPickerFragment.onActivityResult(....) 除了打印一些日志语句外什么都不做。此外，对 super.onActivityResult(...) 的调用完全丢失了。正确的方法是检查请求代码是否由 WizardActivity 发出。如果不是，则调用超级方法会将 onActivityResult(..) 调用路由到片段 SetupContactsFragment。

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    // currently, WizardActivity does not deal with 
    // any onActivityResult callbacks
    super.onActivityResult(requestCode, resultCode, data);
}

SetupContactsFragment 现在可以接收 onActivityResult(...) 回调。尽管如此，我们仍需要识别 onActivityResult(...) 并将其分派到正确的子片段。一种方法是为每个子片段分配不同的 requestCode。在 SetupContactsFragment#onActivityResult(...) 中，我们遍历所有子片段并调用它们的 onActivityResult(...) 方法。由于我们为每个片段分配了不同的 requestCode，因此只会处理其中一个调用。

但是，我不明白为什么您需要三个相同的子片段，每个子片段都包含一个输入字段和一个按钮。这些小部件都可以是 SetupContactsFragemets' ui 的一部分。即使将来规格从 3 个联系人更改为 10 个，您也可以实施一种方法，多次膨胀和添加每一行。

在这种情况下，您将需要 3 个唯一 requestCodes。基于 ImageButton 被按下，不同的 requestCode 被用于 startActivityForResult(...)。在 onActivityResult(...) 中，requestCode 将指示需要更新的 EditText。
