android - 在Webview中长按-应用崩溃

Question

当我在Webview(android)中长按文本时，该应用程序崩溃。我也无法选择文本，因为它会在突出显示文本之前崩溃。通常，该应用程序将显示默认的上下文操作栏，但该应用程序将崩溃。

在我的Activity OnCreate中，我使用了“setWebViewClient”和“LoadURL”。

Web View 位于RelativeLayout(主)内部，在另一个RelativeLayout之下；

这是日志:

Answer 1

分析代码后，我发现问题出在Java文件的开头。它开始于

package com.edireito.dgpro.dgpro;
import...
public class MyActivity extends ActionBarActivity {

当我将“ActionBarActivity”更改为“Activity”时，它起作用了!

谢谢。
