如何将更新的电话号码放入我为Android应用选择的字段中？

Question

如何将更新的电话号码放入我选择的字段？我有选择器返回电话号码，但在错误的字段中。

选择联系人后，电话号码将被放置在错误的字段中。

负责此联系人选择器逻辑的我的片段在我的回购中 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在正确的字段中？

NEW CLUE ：我注意到请求代码根据我选择的字段返回不同的值：第一个字段requestCode 65636，第二个字段requestCode 131172，第三个字段requestCode 196708

Answer 1

您当前的设置有WizardActivity作为父活动，SetupContactsFragment作为片段，ContactPickerFragment作为子片段。当ContactPickerFragment发出startActivityForResult(...)来电时，onActivityResult(...)会收到WizardActivity来电。

问题：

首先，永远不会使用WizardActivity's成员变量contactPickerFragment。它不是你的ui的一部分。因此，在contactPickerFragment.onActivityResult(....)内调用WizardActivity#onActivityResult(...)除了打印几个日志语句之外什么都不做。此外，对super.onActivityResult(...)的调用完全丢失。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super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现在可以收到onActivityResult(...)回调。但是，我们需要识别onActivityResult(...)并将其发送到正确的子片段。这样做的一种方法是为每个子片段分配不同的requestCode。在SetupContactsFragment#onActivityResult(...)内，我们遍历所有子片段并发出对其onActivityResult(...)方法的调用。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，我不明白为什么你需要三个相同的儿童片段，每个片段都有一个输入区域和一个输入区域。一个按钮。这些小部件都可以是SetupContactsFragemets' ui的一部分。即使规范在未来从3个联系人变为10个，您也可以实施一种方法，该方法可以多次膨胀和添加每一行。

在这种情况下，您需要3个唯一requestCodes。根据按下的ImageButton，requestCode使用不同的startActivityForResult(...)。在onActivityResult(...)内，requestCode将指出哪些EditText需要更新。
