Android webview 여러 창

Question

웹보기에 어려움이 있습니다. 양식이있는 웹 페이지를로드하는 webview가 있습니다. 양식에 타겟 _blank 속성이 있습니다. 양식의 작업 URL이로드 된 새 webview 창을 열려면 webview가 필요합니다. 다음 코드를 적용했습니다.

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    web = (WebView) findViewById(R.id.webview1); 
    progressBar = (ProgressBar) findViewById(R.id.progressBar1); 

    web = new WebView(this);   
    WebSettings settings = web.getSettings(); 
    settings.setJavaScriptEnabled(true); 
    settings.setDomStorageEnabled(true); 
    settings.setSupportMultipleWindows(true); 
    settings.setJavaScriptCanOpenWindowsAutomatically(true); 

    web.loadUrl("https://www.example.com/formpage"); 
    web.setWebViewClient(new myWebClient()); 

    web.setWebChromeClient(new WebChromeClient() 
    { 
     /* multiple webview window overload method - start */ 
     public boolean onCreateWindow(WebView view, boolean dialog, boolean userGesture, Message resultMsg) 
     { 
      WebView newWebView = new WebView(view.getContext()); 

      WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj; 
      transport.setWebView(newWebView); 
      resultMsg.sendToTarget(); 
      return true; 
     } 

     /* multiple webview window overload method - end */ 
    }); 

    setContentView(web); 
} 

양식 제출 버튼을 클릭해도 아무런 변화가 없습니다.

Answer 1

새 WebView를보기 계층 구조에 삽입해야합니다.
