每当
webview
捕捉到错误并执行
onreceivederror()
方法时,我就尝试放大新的error.xml布局。我已经完成了一半,但问题是我得到了两种观点。。。我的error.xml视图以及*“网页未找到错误”*视图,请帮助我解决此问题

Fragment.java

public class menu_1 extends Fragment {
private WebView wv;
private TextView tv;
RelativeLayout layout;

@Override
public View onCreateView(final LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_1, container, false);


    wv = (WebView) v.findViewById(R.id.frag1_web);
    wv.loadUrl("file:///res/raw/web1.html");
    WebSettings ws = wv.getSettings();
    ws.setJavaScriptEnabled(true);
    wv.setWebViewClient(new WebViewClient() {
        @Override
        public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
            super.onReceivedError(view, request, error);
            Toast.makeText(getActivity().getApplicationContext(), "Error", Toast.LENGTH_LONG).show();


            LayoutInflater inflater1=getActivity().getLayoutInflater();
            View v=inflater1.inflate(R.layout.show_error,null);
            view.addView(v);
       }

});
    return v;
}



@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState)  {
    super.onViewCreated(view, savedInstanceState);
    //you can set the title for your toolbar here for different fragments different titles
    getActivity().setTitle("Menu 1");
}


}

您可以调用新活动,并在webview所在片段的GetErrorPost布局文件中设置error.xmlused@Hasmukhkachhatiya我正在片段中获取此webview,所以不想调用新活动来显示错误…@Pehlaj添加了片段文件。请参见下面的答案hanax alot@Pehlaj:)它起作用了。。。我可以用同样的方法处理imageview和其他小部件吗。在我需要的时候设置可见性。这也行吗?是的,您可以根据webview的成功/错误显示/隐藏任何视图
