H5做的商城客户端，效果和android原生客户端没多大区别，现在h5是越来越火了， android的小伙伴们又遇到一个新的挑战了。本项目只能学习一下WebViewActivity使用， 但是由于js看不到，所以补发看到里面的方法， 主要代码： @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_webview); ButterKnife.bind(this); String url = getIntent().getStringExtra(EXTRA_URL); mWebView.setWebViewClient(new WebViewClient()); WebSettings webSettings = mWebView.getSettings(); webSettings.setJavaScriptEnable d(true); mWebView.loadUrl(url); setupActionBar(url); } 还有就是CustomTabActivityHelper类封装了 /** * Opens the URL on a Custom Tab if possible. Otherwise fallsback to opening it on a WebView * * @param activity The host activity * @param customTabsIntent a CustomTabsIntent to be used if Custom Tabs is available * @param uri the Uri to be opened * @param fallback a CustomTabFallback to be used if Custom Tabs is not available */ public static void openCustomTab(Activity activity, CustomTabsIntent customTabsIntent, Uri uri, CustomTabFallback fallback) { String packageName = CustomTabsHelper.getPackageNameToUse(activity); //If we cant find a package name, it means there's no browser that supports //Chrome Custom Tabs installed. So, we fallback to the webview if (packageName == null) { if (fallback != null) { fallback.openUri(activity, uri); } } else { customTabsIntent.intent.setPackage(packageName); customTabsIntent.launchUrl(activity, uri); } } /** * Unbinds the Activity from the Custom Tabs Service * @param activity the activity that is connected to the service */ public void unbindCustomTabsService(Activity activity) { if (mConnection == null) return; activity.unbindService(mConnection); mClient = null; mCustomTabsSession = null; } d(true); mWebView.loadUrl(url); setupActionBar(url); } 还有就是CustomTabActivityHelper类封装了 /** * Opens the URL on a Custom Tab if possible. Otherwise fallsback to opening it on a WebView * * @param activity The host activity * @param customTabsIntent a CustomTabsIntent to be used if Custom Tabs is available * @param uri the Uri to be opened * @param fallback a CustomTabFallback to be used if Custom Tabs is not available */ public static void openCustomTab(Activity activity, CustomTabsIntent customTabsIntent, Uri uri, CustomTabFallback fallback) { String packageName = CustomTabsHelper.getPackageNameToUse(activity); //If we cant find a package name, it means there's no browser that supports //Chrome Custom Tabs installed.
