我有两个 Activity SetupActivity 和 DashboardActivity。我正在使用 Firebase 身份验证并检查用户是否存在。新用户申请流程为 打开App->MainActivity->RegisterFragment->SetupActivity->DashboardActivity。这是我的SetupActivity.Java

` 这里我希望用户首先选择个人资料图片，然后必须在编辑文本中填充文本。因此，我需要禁用所有编辑文本，并且在设置个人资料图像后我必须启用它们。为此，我编写了tipdisabled() 和tipEnabled() 方法。但我不知道在哪里正确使用它们。请澄清这一点。
最佳答案
您可以像这样合并代码:
private void tipEnabled(Boolean isEnabled)
{
TIPCurrentLocation.setEnabled(isEnabled);
TIPMobile.setEnabled(isEnabled);
TIPBloodGroup.setEnabled(isEnabled);
TIPFullname.setEnabled(isEnabled);
TIPLastDonated.setEnabled(isEnabled);
PermanentLocation.setEnabled(isEnabled);
}
要实现您的流程，请将 tipEnabled(false) 放在您选择的图像中，单击监听器并将 tipEnabled(true) 放在 onResult 中，我认为在您的情况下是 <强>onActivityResult()。
您应该隔离代码，因为现在您的 Activity 看起来像一个数据转储，目前正在处理太多的职责。尝试创建 Presenter 类、Controller 类或 ViewModel 类，将所有这些功能委托(delegate)给它们。您的 Activity 应该只充当容器，不应该进行验证或任何逻辑处理，而应该进行委托(delegate)。
