android - 如何修复资源未找到异常？

Question

在 Android Studio (3.1.2) 中工作时，我有一个应用程序最初创建为在 InstantApp 管理器下运行。 我相信这就是将其分为 3 个主要目录的原因:app、base、feature。

注意:突出显示相关文件...

无论如何，问题是找不到资源。

我正在尝试自定义一个 SeekBar 并使用渐变形状作为背景。在 feature.res.values.style.xml 中:

<?xml version="1.0" encoding="utf-8"?>

<style name="alphaSliderStyle" parent="@android:style/Widget.SeekBar">
    <item name="android:indeterminateOnly">false</item>
    <item name="android:progressDrawable">@drawable/alpha_progress</item>
</style>

我的理解是 alpha_progress.xml 文件应该在 feature.res.drawable 下。但是，在运行该应用程序时，一旦显示自定义 SeekBar 的 View 被实例化，我就会得到以下内容(摘录):

相关位似乎是:

Caused by: android.content.res.Resources$NotFoundException: Drawable com.razorware.cloudcard.app:drawable/alpha_progress with resource ID #0x7f08005b
Caused by: android.content.res.Resources$NotFoundException: File res/drawable/alpha_progress.xml from drawable resource ID #0x7f08005b

...特别是它正在查找 app.res.drawable 位置(如果我理解正确的话)。

就其值(value)而言，以下是另外两个相关drawables的内容:

// alpha_progress.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <bitmap android:src="@drawable/alpha_color_sample" />
    </item>
</layer-list>

// alpha_color_sample.xml
<?xml version="1.0" encoding="utf-8"?>
<shape  xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    android:id="@+id/colorSample"
    android:layout_width="135dp"
    android:layout_height="45dp">

    <gradient android:angle="90"
        android:startColor="#FFFFFFFF"
        android:endColor="#00FFFFFF" />
</shape>

Answer 1

Caused by: android.content.res.Resources$NotFoundException: Drawable com.razorware.cloudcard.app:drawable/alpha_progress with resource ID #0x7f08005b
Caused by: android.content.res.Resources$NotFoundException: File res/drawable/alpha_progress.xml from drawable resource ID #0x7f08005b

Resources.NotFoundException

This exception is thrown by the resource APIs when a requested resource can not be found.

你应该设置 android:drawable 在 item 内 部分。

<item android:id="@android:id/background"
     android:drawable="@drawable/alpha_color_sample">
 </item>

我假设 <bitmap android:src 产生问题是因为， alpha_color_sample 不是有效的位图。

更改后 Clean-Rebuild-Run .
