java - "Validates resource references inside Android XML files"

Question

我在使用“android:name="ManageApps"”的第二个 Activity 上收到此错误，

'net.web44.jimappdev.thecoincollector.ManageApps' is not assignable to 'android.app.Activity' Validates resource references inside Android XML files.

这是Manifest.xml，

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

这里是MainActivity.java，

        }

Answer 1

看起来您的 ManageApps Activity 不在包 namespace 中:

<activity
    android:name="ManageApps"
    android:label="@string/app_name">
    <intent-filter>
        <action android:name="net.web44.jimappdev.thecoincollector.manageapps" />

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

名称必须以 . 开头才能被视为包 namespace 的一部分:

    android:name=".ManageApps"

此外，尽管我不是 100% 确定，但我始终假设操作名称区分大小写。在上面的 list 部分中，您使用 manageapps 作为操作名称的最后一部分，而在 Java 代码中构建 Intent 时以混合大小写的方式使用它:

startActivity(new Intent("net.web44.jimappdev.thecoincollector.ManageApps"));
