“标签<活动>属性名称包含无效字符''。 " Android Manifest [英] "Tag <Activity > attribute name has invalid character ' '. " Android Manifest

问题描述

我在Android Manifest中收到错误Tag属性名称有无效字符'。，而没有明显无效的字符。这是代码：

I am getting the error "Tag attribute name has invalid character ' '. " in the Android Manifest, while there is no obviously invalid character. Here is the code:

<activity
        android:name="Quiz 31"
        android:configChanges="orientation|keyboardHidden"
        android:label="Quiz 31"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar" >
        <intent-filter>
            <action android:name="com.SoulSlayerAbad.AMQ.QUIZ31" />

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

如您所见，代码中没有''字符。有谁知道为什么会这样？需要注意的一点是，我使用Eclipse控制台内部运行的几行Java生成了这段代码。代码是：

As you can see, no ' ' character in the code. Does anyone know why this is happening? One thing to note is that I generated this piece of code using a few lines of Java run inside of Eclipse console. The code for that is:

        int Begin = 0, End = 0; 
    Scanner sc = new Scanner(System.in);

    String Text = " <activity "+
            "android:name=\"Quiz "+Begin+"\" "+
            "android:configChanges=\"orientation|keyboardHidden\" "+
            "android:label=\"Quiz "+Begin+"\" "+
            "android:screenOrientation=\"portrait\" "+
            "android:theme=\"@android:style/Theme.NoTitleBar\" > "+
            "<intent-filter> "+
                "<action android:name=\"com.SoulSlayerAbad.AMQ.QUIZ"+Begin+"\" /> "+

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

    System.out.println("Begining:");
    Begin = sc.nextInt();
    System.out.println("End At:");
    End = sc.nextInt();
    while(Begin <= End){
        System.out.println(Text);
        Begin++;
    }

推荐答案

android：name 应该引用代表活动的类路径。它不得包含任何特殊字符或空格。

android:name is supposed to have reference of your class path which represents the activity. It must not contain any special characters or spaces.

例如：

android:name="com.json.test.MainActivity"

这里， MainActivity 是扩展活动的类文件。

Here, MainActivity is the class file which extends an Activity.
