Question

我似乎只在API 15设备上收到此错误。它似乎是动画或其他东西的问题，但我不知道如何解决这个问题。当我启动我的应用程序时，它强制关闭。但是，在API 17上，它可以正常工作。

这是似乎导致它的一行：

PreferenceManager.setDefaultValues(this, R.xml.preferences, false);

这是堆栈跟踪：

Answer 1

我知道这是一个古老的问题，但我想我会分享一个解决方案。

您的原始问题中提供的信息量有限，但是我认为此解决方案仍然适用。

我查看了有关创建首选项屏幕的指南（我假设您也这样做）。该指南可以在Android Developer Guides网站上找到。

他们似乎错过了设置Activity或[AppCompatActivity] []中使用的称为setContentView(View)的实际活动内容（按钮，布局等屏幕组件）的电话。 / p>

TL; DR

添加到您的SettingsActivity.java文件

setContentView(R.layout.my_settings_activity_layout);

其中my_settings_activity_layout是相应的MySettingsActivity.java布局文件的文件名

android.view.InflateException：二进制XML文件行＃2：错误导致类alpha
