Add the wireless Taobao page to android webview and click the baby details link to enter the baby details page. The problem cannot be returned_html/css_WEB-ITnose

In the past few days, I have been trying to introduce the wireless Taobao page into the webview. I found that after clicking on the product details to enter the page, I cannot return.
At first, I followed what most people on the Internet said to display the link in the same webview. Page, thus overloading the shouldOverrideUrlLoading method of WebClient

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

I found that after clicking the baby details link page, I cannot return. I have tried various methods, but it cannot be solved!
Finally, I found that the solution is: there is no need to rewrite the shouldOverrideUrlLoading method of WebClient; you only need to rewrite the onPageStarted method of WebClient, without writing anything in it. The code is as follows:

		mWebView = (WebView) findViewById(R.id.webView);		mWebView.setWebViewClient(new WebViewClient() {			@Override			public void onPageStarted(WebView view, String url, Bitmap favicon) {				super.onPageStarted(view, url, favicon);			}		});		WebSettings webSettings = mWebView.getSettings();		//支持js        webSettings.setJavaScriptEnabled(true);        //支持对网页缩放        webSettings.setSupportZoom(true);        //支持android4.0        webSettings.setBuiltInZoomControls(true);        //默认缩放模式        webSettings.setDefaultZoom(ZoomDensity.CLOSE);        mWebView.setInitialScale(100);        //载入url

mWebView.loadUrl(" http ://m.taobao.com/channel/chn/mobile/tejia_taoke.php?pid=mm_11443354_6190798_21526785");
