一旦我在android模拟器或手机上启动我的应用程序，它就会崩溃，不幸的是，应用程序已经停止 任何帮助都将不胜感激。谢谢
我正在尝试将我的网站转换为android应用程序。您正在将网络视图初始化为相对视图。请看下面的一行
mWebView= (WebView) findViewById(R.id.activity_main_webview);
mWebView = (WebView) findViewById(R.id.textView);
请尝试对视图使用更具描述性的ID。例如，WebView的ID可能是WebView而不是textView:。如果查看xml，则您的活动\u main\u WebView是相对的。您正在MainActivity.java中将其转换为WebView 你可能想这样做
mWebView= (WebView) findViewById(R.id.textView);
如果您查看xml，您的activity\u main\u webview是一个相对的视图。您正在MainActivity.java中将其强制转换为WebView。您的WebView的id是textview。您正在尝试获取活动\主\网络视图，它是一个布局，而不是网络视图。改为使用textview。您的xml文件中是否有id为activity\u main\u webview的RelativeLayout？@AnanBatra请尝试按照我在回答中所述重命名您的WebViews id，仍然可以获得same@AnanBatra您必须得到不同的异常与同一异常中的错误相同，或者不幸的是，“应用程序”意外停止，应用程序已停止
