致命异常：android.content.res.Resources$NotFoundException：Drawable org.radarcns.detail：drawable/status_searching，资源 ID #0x7f080130

Question

我遇到异常：

Fatal Exception: android.content.res.Resources$NotFoundException: Drawable org.radarcns.detail:drawable/status_searching with resource ID #0x7f080130


Caused by android.content.res.Resources$NotFoundException: Resource "org.radarcns.detail:drawable/status_searching" (7f080130) is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f080130 a=11 r=0x7f080130}

SourceRowView 中出现此错误的代码如下：

    private val mStatusIcon: ImageView = findViewById(R.id.status_icon)
    mStatusIcon.setImageResource(R.drawable.status_searching)

R.drawable.status_searching 存在于 src/main/res/drawable 中，其中包含：

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/ic_searching" />
</layer-list>

现在@drawable/ic_searching.png以png格式存在于drawable-hdpi、drawable-mdpi、drawable-xhdpi和drawable-xxhdpi中。

即使所有资源都存在，但它给出了 ResourceNotFound，我不明白为什么会发生这种情况？

我推荐使用以下功能。

imageView.setImageDrawable(ContextCompat.getDrawable(activity, R.drawable.your_image));
