public void ShowTrack(String smetaout,String stitleout){ 
    AlertDialog.Builder alert = new AlertDialog.Builder(this); 
    alert.setTitle(stitleout); 

    WebView wv = new WebView(this); 

    wv.setWebViewClient(new WebViewClient() { 

     @Override 
      public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) { 
      Log.d("My Webview", "shouldOverrideUrlLoading"+urlNewString); 
       if (!loadingFinished) { 
        redirect = true; 
       } 

      loadingFinished = false; 
      view.loadUrl(urlNewString); 
      Log.d("My Webview", urlNewString); 
      return false; 
      } 

      public void onPageStarted(WebView view, String url) { 
       Log.d("My Webview", "onPageStarted"+url); 
       loadingFinished = false; 

      } 

      @Override 
      public void onPageFinished(WebView view, String url) { 
       if(!redirect){ 
        loadingFinished = true; 
       } 

       if(loadingFinished && !redirect){ 

       } else{ 
        redirect = false; 
       } 
       Log.d("My Webview", "onPageFinished"+url); 
      } 

    }); 
    wv.loadUrl(smetaout); 
    alert.setView(wv); 
    alert.setNegativeButton("Close", new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int id) { 
      dialog.dismiss(); 
     } 
    }); 
    alert.show(); 
} 

Answer 1

在.loadUrl之前插入任何延迟（定时器，异步等）。例如：

new CountDownTimer(5000, 5000) 
{ 
    public void onTick(long millisUntilFinished) {} 
    public void onFinish() 
    { 
     view.loadUrl(urlNewString); 
    } 
}.start();     

Answer 2

试试这个：

public void ShowTrack(String smetaout,String stitleout){ 
    AlertDialog.Builder alert = new AlertDialog.Builder(this); 
    alert.setTitle(stitleout); 

    WebView wv = new WebView(this); 

    // Progress dialog starts 
    ProgressDialog progressDialog = ProgressDialog.show(YourActivity.this, "", "Loading... ",true ,true); 

    wv.setWebViewClient(new WebViewClient() { 

     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) { 
      Log.d("My Webview", "shouldOverrideUrlLoading"+urlNewString); 
      if (!loadingFinished) { 
       redirect = true; 
      } 

      loadingFinished = false; 
      view.loadUrl(urlNewString); 
      Log.d("My Webview", urlNewString); 
      return false; 
     } 

     public void onPageStarted(WebView view, String url) { 
      Log.d("My Webview", "onPageStarted"+url); 
      loadingFinished = false; 

     } 

     @Override 
     public void onPageFinished(WebView view, String url) { 

      final Handler handler = new Handler(); 
      handler.postDelayed(new Runnable() { 
       @Override 
       public void run() { 
        // Do something after 5s = 5000ms 
        progressDialog.dismiss(); 
       } 
      }, 5000); 

      if(!redirect){ 
       loadingFinished = true; 
      } 

      if(loadingFinished && !redirect){ 

      } else{ 
       redirect = false; 
      } 
      Log.d("My Webview", "onPageFinished"+url); 
     } 

    }); 
    wv.loadUrl(smetaout); 
    alert.setView(wv); 
    alert.setNegativeButton("Close", new DialogInterface.OnClickListener() { 
     @Override 
     public void onClick(DialogInterface dialog, int id) { 
      dialog.dismiss(); 
     } 
    }); 
    alert.show(); 
} 

我希望这是你想要的。
