WebView的几个常见功能使用方法

WebView.setBackgroundColor(0);//先设置背景色为transparent 
WebView.setBackgroundResource(R.drawable.yourImage);//然后设置背景图片 

mWebView.setWebViewClient(new WebViewClient() 
{   
 @Override 
public void onPageFinished(WebView view, String url)  
{ 
//结束 
super.onPageFinished(view, url); 
} 
 @Override 
 public void onPageStarted(WebView view, String url, Bitmap favicon)  
 { 
 //开始 
 super.onPageStarted(view, url, favicon); 
 } 
}); 

webview.setWebChromeClient(new MyWebChromeClient())即可:
class MyWebChromeClient extends WebChromeClient { 
@Override 
public void onProgressChanged(WebView view, int newProgress) { 
// TODO Auto-generated method stub 
super.onProgressChanged(view, newProgress); 
} 
} 
例如： 
public class WebPageLoader extends Activity { 
  final Activity activity = this; 
 
 
  @Override 
  public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    this.getWindow().requestFeature(Window.FEATURE_PROGRESS); 
    setContentView(R.layout.main); 
    WebView webView = (WebView) findViewById(R.id.webView); 
    webView.getSettings().setJavascriptEnabled(true); 
    webView.getSettings().setSupportZoom(true); 
    webView.setWebChromeClient(new WebChromeClient() { 
      public void onProgressChanged(WebView view, int progress) { 
        activity.setTitle("Loading..."); 
        activity.setProgress(progress * 100); 
        if (progress == 100) 
          activity.setTitle(R.string.app_name); 
      } 
    }); 
    webView.setWebViewClient(new WebViewClient() { 
      public void onReceivedError(WebView view, int errorCode, 
          String description, String failingUrl) { // Handle the error 
      } 
 
 
      public boolean shouldOverrideUrlLoading(WebView view, String url) { 
        view.loadUrl(url); 
        return true; 
      } 
    }); 
    webView.loadUrl("http://www.sohu.com"); 
  } 
}

webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);  
webView.setHorizontalScrollBarEnabled(false);  
webView.getSettings().setSupportZoom(true);  
webView.getSettings().setBuiltInZoomControls(true);  
webView.setInitialScale(70);  
webView.setHorizontalScrollbarOverlay(true);
