【中文标题】错误 net::err_unknown_url_scheme 电话:【英文标题】:Error net::err_unknown_url_scheme tel: 【发布时间】:2017-05-05 10:03:26 【问题描述】:

我用 android Studio 构建了一个 webview 应用程序,当我从应用程序返回错误 net::err_unknown_url_scheme 按此链接时,在我的网站上我有一个类似 tel:0752118 的链接

这是我的 MainActivity.java

  package totalonlinesrl.totalonline;

import android.content.Context;
import android.graphics.Bitmap;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.net.Uri;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.LinearLayout;
import android.widget.ProgressBar;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity 
    private WebView webView;
    private ProgressBar progressBar;
    private LinearLayout layoutProgress;
    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        webView = (WebView) findViewById(R.id.webView);
        progressBar = (ProgressBar) findViewById(R.id.progressBar);
        layoutProgress = (LinearLayout) findViewById(R.id.layoutProgress);
        webView.setVisibility(View.GONE);
        WebSettings settings = webView.getSettings();
        settings.setjavascriptEnabled(true);
        settings.setBuiltInZoomControls(true);
        settings.setSupportZoom(true);
        settings.setDisplayZoomControls(false);
        webView.setWebViewClient(new WebViewClient() 
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) 
                view.loadUrl(url);
                return true;
            

            @Override
            public void onPageFinished(WebView view, String url) 
                webView.setVisibility(View.VISIBLE);
                layoutProgress.setVisibility(View.GONE);
                progressBar.setIndeterminate(false);
                super.onPageFinished(view, url);

            

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) 
                layoutProgress.setVisibility(View.VISIBLE);
                progressBar.setIndeterminate(true);
                super.onPageStarted(view, url, favicon);
            
        );
        if(isOnline()) 
            webView.loadUrl("https://total-online.eu/");
         else 
            String summary = "<html><body><font color='red'>No Internet Connection</font></body></html>";
            webView.loadData(summary, "text/html", null);
            toast("No Internet Connection.");
        
    
    private void toast(String message) 
        Toast.makeText(this, message, Toast.LENGTH_LONG).show();
    

    private boolean isOnline() 
        ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo netInfo = cm.getActiveNetworkInfo();
        return (netInfo != null && netInfo.isConnected());
    

有什么办法吗?

如果链接包含地理位置、电话号码和电子邮件地址,您可以使用下面的代码切换到搜索屏幕和邮件客户端。

public boolean shouldOverrideUrlLoading(WebView view, String url) 
    if (url.startsWith("tel:")) 
        Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
        startActivity(intent);
        view.reload();
        return true;
     else if (url.contains("mailto:")) 
        view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
        return true;
     else if(url.contains("geo:")) 
        view.getContext().startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse(url)));
        return true;
     else 
        view.loadUrl(url);
        return true;
