我认为，有一个错误。可能/**
* Called when the fragment is visible to the user and actively running. Resumes the WebView.
*/
@Override
public void onPause() {
super.onPause();
mWebView.onPause();
}
/**
* Called when the fragment is no longer resumed. Pauses the WebView.
*/
@Override
public void onResume() {
mWebView.onResume();
super.onResume();
}
应替换为onPause，反之亦然。如果我替换了复制粘贴类中的行为，我可以得到任何错误吗？
