Question

在我的片段中，我想粘贴一个相对布局，包括我的自定义progrssBar。加载android:progressDrawable="@drawable/loadingbackground"时，总是出现相同的错误： android.view.InflateException: Binary XML file line #30: Binary XML file line #30: Error inflating class android.widget.ProgressBar

通过调试，我发现这确实是loadingbackground.xml (V24)导致错误的原因。

即使loadingbackground.xml为空，也会出现错误。这是片段中禁止的吗？

Answer 1

问题：...xml(24) 我不知道24是什么意思，但这就是它不起作用的原因... 只需创建一个新的可绘制文件并传递内容即可。

但是请注意文件的背面没有（24）。

我对此一无所知，但这可能是与该错误有关的其他一些问题的解决方案。

如何修复错误：XML文件导致类android.widget.ProgressBar膨胀错误
