java - Lollipop 5.1 设备上的新 WebView 出现异常

Question

这个问题已经有答案了:

android.view.InflateException Error inflating class android.webkit.WebView (21 个回答)

已关闭 4 年前。

我尝试将 WebView 添加到我的 Activity 中:

WebView webView = new WebView(this);

在所有设备上都可以正常工作，但在 Android Lollipop 5.1(仅限)设备上，我在这一行中遇到了异常:

我做错了什么以及在 Android Lollipop 5.1 设备上解决问题的最佳方法是什么。

可以通过捕获错误，然后使用应用程序上下文创建 WebView 来解决此问题:

try {
    webView = new WebView(this);
}
catch (Resources.NotFoundException e) {
    // Some older devices can crash when instantiating a WebView, due to a Resources$NotFoundException
    // Creating with the application Context fixes this, but is not generally recommended for view creation
    webView = new WebView(getApplicationContext());
}

通常不鼓励使用应用程序上下文创建 View ，但这里是一个不错的后备方案。
