H5做的商城客户端，效果很不错
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.setJavaScriptEnabled(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;
}
