1. 開啟網頁時不呼叫系統瀏覽器， 而是在本WebView中顯示：

mWebView.setWebViewClient(new WebViewClient(){
      @Override
      public boolean shouldOverrideUrlLoading(WebView view, String url) {
          view.loadUrl(url);
          return true;
      }
  });

2. 通過java程式碼呼叫javascript

WebSettings webSettings =   mWebView .getSettings();       
webSettings.setJavaScriptEnabled(true); 
mWebView.addJavascriptInterface(new Object() {       
            public void clickOnAndroid() {       
                mHandler.post(new Runnable() {       
                    public void run() {       
                        webview.loadUrl("javascript:wave()");       
                    }       
                });       
            }       
        }, "demo");  
 

3. 按返回鍵時， 不退出程式而是返回上一瀏覽頁面：

public boolean onKeyDown(int keyCode, KeyEvent event) {       
        if ((keyCode == KeyEvent.KEYCODE_BACK) &&   mWebView .canGoBack()) {       
            webview.goBack();       
                   return true;       
        }       
        return super.onKeyDown(keyCode, event);       
    }
 

4. 開啟頁面時， 自適應螢幕：

WebSettings webSettings =   mWebView .getSettings();       
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);

5. 便頁面支援縮放：

WebSettings webSettings =   mWebView .getSettings();       
 webSettings.setJavaScriptEnabled(true);  
 webSettings.setBuiltInZoomControls(true);
webSettings.setSupportZoom(true);
