解決方法：以"http","https"開頭的url在本頁用webview進行載入，其他連結進行跳轉

private class MyWebViewClient extends WebViewClient{
	@Override 
	public boolean shouldOverrideUrlLoading(WebView view, String url) { 
			if(url.startsWith("http:") || url.startsWith("https:") ) { 
		    view.loadUrl(url);  
		    return false;  
			}else{
				Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));  
		    startActivity(intent);
		    return true;  
			}
	}  
			
	
}
