我怎样才能做出响应？
mWebView = (WebView) findViewById(R.id.activity_main_webview);
WebSettings webSettings = mWebView.getSettings();
mWebView.setInitialScale(1);
webSettings.setDomStorageEnabled(true);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setAllowContentAccess(true);
mWebView.setScrollbarFadingEnabled(false);

<h2>The w3-mobile Class</h2>
<p>The <strong>w3-mobile</strong> class adds mobile-first responsivenss to any element.</p>
<p>It adds display:block and width:100% to an element on screens that are less than 600px wide.</p>
<p>Resize the browser window to see the effect:</p>
<button class="w3-button w3-black w3-mobile">Home</button>
<button class="w3-button w3-black w3-mobile">Link 1</button>
<button class="w3-button w3-black w3-mobile">Link 2</button>
<button class="w3-button w3-black w3-mobile">Link 3</button>
</div>
</body>
