ブラウザで外部Webページを開く方法は？

Question

私は外部リンクを開くためのコードを統合するのに助けが必要です。私はブラウザでリンクを開くためにいくつかのコードを追加しましたが、webviewは単にリンクを開いてブラウザに指示しません。私のURLは正しいです。これはwebviewアプリケーションです。

Answer 1

WebViewClient webViewClient= new WebViewClient(){ 
@Override 
public boolean shouldOverrideUrlLoading(WebView view, String url){ 
    return true; 
} 
@Override 
public void onLoadResource(WebView view, String url){ 
    try { 
     Intent i = new Intent(Intent.ACTION_VIEW); 
     i.setData(Uri.parse(url)); 
     startActivity(i); 
    } catch (ActivityNotFoundException ignored) { 
    } 
    } 
} 

Answer 2

問題は、あなたが（setWebViewClient()は現在のハンドラを置き換え）を2回WebViewClientをオーバーライドするので、あなたは、あなたが以前に書いたshouldOverrideUrlLoadingの実施を却下されている最後の時間です。 onReceivedErrorの実装をshouldOverrideUrlLoadingと同じWebViewClientインスタンスに置き、2番目のWebViewClientインスタンスを削除します。あなたのコードはすべきで、このようなものになります[？どのような状況下で、私はより速く答えを得るために、私の質問に、「緊急」または他の同様の句を追加することができ]

webView.setWebViewClient(new WebViewClient(){ 
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 
     if (url != null && url.startsWith("https://studywire.eulj.io")) { 
      return false; 
     } else { 
      view.getContext().startActivity(
         new Intent(Intent.ACTION_VIEW, Uri.parse(url))); 
      return true; 
      } 
     } 
    }); 

    public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
     webView.loadUrl("file:///android_asset/noInternet.html"); 
    }
