只让本应用程序的webview加载网页，而不调用外部浏览器打开的办法就是：设置WebViewClient，并重写WebViewClient的shouldOverrideUrlLoading方法返回true

		mWebView.setWebViewClient(new WebViewClient(){

			@Override
			public boolean shouldOverrideUrlLoading(WebView view, String url) {
				// TODO Auto-generated method stub
				view.loadUrl(url);
				return true;
			}
		});

    /** 。。。。。。。
     * @param view The WebView that is initiating the callback.
     * @param url The url to be loaded.
     * @return True if the host application wants to leave the current WebView
     *         and handle the url itself, otherwise return false.
     */
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        return false;
    }
