android片段webview加載指標

Question

我想添加加載指標到我的webview有沒有解決方案嗎？

預先感謝您！

import com.actionbarsherlock.app.SherlockFragment; 

public class Showing_now extends SherlockFragment{ 

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View mainView = (View) inflater.inflate(R.layout.activity_showing_now, container, false); 
    WebView webView = (WebView) mainView.findViewById(R.id.webViewsn); 

    webView.setWebViewClient(new MyWebViewClient()); 
    webView.getSettings().setPluginsEnabled(true); 
    webView.getSettings().setBuiltInZoomControls(false); 
    webView.getSettings().setSupportZoom(false); 
    webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true); 
    webView.getSettings().setAllowFileAccess(true); 
    webView.getSettings().setDomStorageEnabled(true); 
    webView.getSettings().setJavaScriptEnabled(true); 
    webView.getSettings().setPluginState(PluginState.ON); 
    webView.loadUrl("http://www.myweburl.com"); 
    return mainView; 
} 
    private class MyWebViewClient extends WebViewClient { 

    } 
}

如果您使用ActionbarSherlock，和Android支持庫，我建議使用此設置

protected void onCreate(Bundle savedInstanceState) { 
    requestWindowFeature(Window.FEATURE_PROGRESS); 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.webview); 
    setSupportProgressBarVisibility(true); 
    WebView mWebView = (WebView) findViewById(R.id.WebView); 
    mWebView.setWebChromeClient(new WebChromeClient() { 
     public void onProgressChanged(WebView view, int progress) { 
      setSupportProgress(progress * 100); 
      if (progress == 100) { 
       setSupportProgressBarVisibility(false); 
      } 
     } 
    }); 
    webView1.loadUrl("http://www.google.com"); 
} 

那麼好看多了，你只需要調用requestWindowFeature(Window.FEATURE_PROGRESS)您設置ContentView，之後前，使用setSupportProgressBarVisibility(true);設置ProgressBar在您的webview第一次加載時創建。爲了讓進度視圖在內容加載完成時停止，您需要創建一個新的WebChromeClient並添加OnProgressChanged，並在進度達到100％時將ProgressBar的可見性設置爲false
