【问题描述】：

android webview 不加载主页，但加载所有其他页面！奇怪的是，当我从应用程序的原始站点菜单中单击主页时，它会正确加载主页而没有任何问题，但是如果我尝试从顶部导航菜单中单击它，它根本不会加载！

package com.example.couponcheetah;

import android.webkit.WebResourceRequest;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class WebViewController extends WebViewClient 
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) 
        view.getSettings().setjavascriptEnabled(true);
        view.getSettings().setDomStorageEnabled(true);
        view.getSettings().setSupportZoom(false);
        view.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

        // hide element by id
        view.loadUrl("javascript:(function()  " +
                "document.getElementById('site-navigation').style.display='none';)()");
        view.loadUrl(url);
        return true;
    

这是家庭片段：

package com.example.couponcheetah.ui.home;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;

import androidx.annotation.NonNull;
import androidx.fragment.app.Fragment;
import androidx.lifecycle.ViewModelProvider;

import com.example.couponcheetah.WebViewController;
import com.example.couponcheetah.R;

public class HomeFragment extends Fragment 

    private HomeViewModel homeViewModel;

    public View onCreateView(@NonNull LayoutInflater inflater,
                             ViewGroup container, Bundle savedInstanceState) 
        homeViewModel =
                new ViewModelProvider(this).get(HomeViewModel.class);
        View root = inflater.inflate(R.layout.fragment_home, container, false);

        WebView webView=root.findViewById(R.id.web_view_home);
        webView.loadUrl("https://couponcheetah.com");
        webView.setWebViewClient(new WebViewController());
        return root;
    

【参考方案1】：

如果我正确理解您的问题 尝试将您的代码放在 onstart 而不是 oncreateView as

public class HomeFragment extends Fragment 

    private HomeViewModel homeViewModel;
     private WebView webView;
    public View onCreateView(@NonNull LayoutInflater inflater,
                             ViewGroup container, Bundle savedInstanceState) 
        homeViewModel =
                new ViewModelProvider(this).get(HomeViewModel.class);
        View root = inflater.inflate(R.layout.fragment_home, container, false);

        webView=root.findViewById(R.id.web_view_home);
        return root;
    
    
    // impelment funcation onStart and put your code
    webView.loadUrl("https://couponcheetah.com");
        webView.setWebViewClient(new WebViewController());
