Question

我无法访问strings.xml：

Log.i("url",context.getString(R.string.url));

在strings.xml中

<string name="url">http://myip.com/</string>

它会产生一个例外：

12-12 14:52:44.551: E/AndroidRuntime(3534): FATAL EXCEPTION: WebViewCoreThread

Answer 1

尝试从Strings.xml

获取字符串

String strurl=context.getresources().getString(R.string.url);
Log.i("url ",strurl);

Answer 2

context显然是null，如果您在该行上获得NullPointerException。
