android - 向项目中添加资源 xml 文件会导致运行时异常

Question

我想在我的 Android 应用程序项目中包含一个资源 xml 文件，以保存一些旨在具有特定用途的字符串值categories_names.xml，将其复制到res/values文件夹中，但是一旦我尝试运行应用程序，它就会退出并抛出InflateException. 奇怪的是，甚至无法从启动器活动中访问此资源文件。这怎么可能？我在下面报告回溯。

编辑 2：我发现将这些字符串资源与其他字符串资源放在 res/values/strings.xml 文件中具有相同的效果，所以我猜这些资源存在一些问题。我在下面列出它们。

<string name="category_angles">Angles</string>
<string name="category_area">Area</string>
<string name="category_electricity">Electricity</string>
<string name="category_kitchen">Kitchen</string>
<string name="category_data">Data</string>
<string name="category_energy">Energy</string>
<string name="category_force">Force</string>
<string name="category_frequency">Frequency</string>
<string name="category_illumination">Illumination</string>
<string name="category_luminance">Luminance</string>
<string name="category_lenght">Lenght</string>
<string name="category_mass">Mass</string>
<string name="category_power">Power</string>
<string name="category_pressure">Pressure</string>
<string name="category_temperature">Temperature</string>
<string name="category_time">Time</string>
<string name="category_typography">Typography</string>
<string name="category_torsion">Torsion</string>
<string name="category_currencies">Currencies</string>
<string name="category_speed">Speed</string>
<string name="category_internet_speed">Internet speed</string>
<string name="category_volume">Volume</string>

编辑 3：我检查了我的 R.java 生成的文件以确保它不是资源生成器问题，但它看起来不错。粘贴下面的字符串部分。

    public static final int action_settings=0x7f060017;

我知道这是一个迟到的回应，但我遇到了同样的问题，删除我的“android:textAllCaps”样式解决了这个问题。我不知道为什么..仍在调查。

你可以尝试一些事情（如果你还没有）看看你是否取得了进展：

在布局中使用硬编码字符串，而不是从 strings.xml 加载它们。

似乎是与设置字体系列有关的这一行的 TextView init。

从您的布局 xml 中，您似乎正在使用自定义字体系列（“Lato”）。

<TextView
    android:id="@+id/displayTextView"
    ...
    android:fontFamily="Lato"
    ...
/>

您的应用程序支持吗？如果我错了，请纠正我，但据我所知，默认 Roboto 字体的系统支持的字体系列（自 API 16 起）是“sans-serif”、“sans-serif-light”、“sans-serif-浓缩”或“无衬线薄”。

当系统无法通过反射找到并实例化您的自定义字体时，可能会“可能”导致后续的InflateException.

因此，可能值得尝试先使用默认系统字体，看看是否能解决问题。

您的问题在于检索字符串值。线索在这里...

看起来它正在尝试检索一个不存在的字符串值，或者它认为不存在。看看字符串文件中是否有任何可能导致它无法正确解析的内容。

从你提供的内容来看，我不能比这更具体了。

这意味着它是由过度索引 Array 而不是它的大小引起的。所以可能是您使用了高于数组大小的资源索引。所以首先检查一下，然后尝试运行。

您是否要为 Button 充气？因为这似乎行不通，这可能是获得例外的一个原因。如果你是，这就是方法：

LinearLayout view = (LinearLayout) LayoutInflater.from(this).inflate(R.layout.yada_layout, null);
Button b = (Button) view.findViewById(R.id.clearButton);
