Otwieranie niestandardowego WebView z "Powered By Chrome" z menu akcji

Question

Niedawno zauważyłem, że po otwarciu linku w niektórych z kilku aplikacji na Androida mają podobny wygląd i niestandardowe menu akcji z opcją "Powered by Chrome "poniżej menu niestandardowego. Jakiego składnika używa się w tym czy nadal jest to Chromium WebView? Mam nadzieję, że dodam je do moich kolejnych projektów, które wymagają otwarcia odnośnika wewnątrz aplikacji.

Jest Chrome Custom Tabs. Możesz zobaczyć przykładowy kod z Google Chrome here.

Spróbuj następujące klasy util:

public class CustomTabs { 

    private static final int TOOLBAR_SHARE_ITEM_ID = 1; 

    public static void openTab(Context context, String url) { 
     CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder(); 

     enableUrlBarHiding(builder); 
     setToolbarColor(context, builder); 
     setSecondaryToolbarColor(context, builder); 
     setCloseButtonIcon(context, builder); 
     setShowTitle(builder); 
     setAnimations(context, builder); 
     setShareActionButton(context, builder, url); 
     addToolbarShareItem(context, builder, url); 
     addShareMenuItem(builder); 
     addCopyMenuItem(context, builder); 

     CustomTabsIntent customTabsIntent = builder.build(); 
     customTabsIntent.launchUrl(context, Uri.parse(url)); 
    } 

    /* Enables the url bar to hide as the user scrolls down on the page */ 
    private static void enableUrlBarHiding(CustomTabsIntent.Builder builder) { 
     builder.enableUrlBarHiding(); 
    } 

    /* Sets the toolbar color */ 
    private static void setToolbarColor(Context context, CustomTabsIntent.Builder builder) { 
     builder.setToolbarColor(ContextCompat.getColor(context, R.color.colorPrimary)); 
    } 

    /* Sets the secondary toolbar color */ 
    private static void setSecondaryToolbarColor(Context context, CustomTabsIntent.Builder builder) { 
     builder.setSecondaryToolbarColor(ContextCompat.getColor(context, R.color.colorPrimary)); 
    }  

    /* Sets the Close button icon for the custom tab */ 
    private static void setCloseButtonIcon(Context context, CustomTabsIntent.Builder builder) { 
     builder.setCloseButtonIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_arrow_back)); 
    } 

    /* Sets whether the title should be shown in the custom tab */ 
    private static void setShowTitle(CustomTabsIntent.Builder builder) { 
     builder.setShowTitle(true); 
    } 

    /* Sets animations */ 
    private static void setAnimations(Context context, CustomTabsIntent.Builder builder) { 
     builder.setStartAnimations(context, R.anim.slide_in_right, R.anim.slide_out_left); 
     builder.setExitAnimations(context, R.anim.slide_in_left, R.anim.slide_out_right); 
    } 

    /* Sets share action button that is displayed in the Toolbar */ 
    private static void setShareActionButton(Context context, CustomTabsIntent.Builder builder, String url) { 
     Bitmap icon = BitmapFactory.decodeResource(context.getResources(), android.R.drawable.ic_menu_share); 
     String label = "Share via"; 

     Intent shareIntent = new Intent(Intent.ACTION_SEND); 
     shareIntent.putExtra(Intent.EXTRA_TEXT, url); 
     shareIntent.setType("text/plain"); 

     PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, shareIntent, PendingIntent.FLAG_UPDATE_CURRENT); 

     builder.setActionButton(icon, label, pendingIntent); 
    } 

    /* Adds share item that is displayed in the secondary Toolbar */ 
    private static void addToolbarShareItem(Context context, CustomTabsIntent.Builder builder, String url) { 
     Bitmap icon = BitmapFactory.decodeResource(context.getResources(), android.R.drawable.ic_menu_share); 
     String label = "Share via"; 

     Intent shareIntent = new Intent(Intent.ACTION_SEND); 
     shareIntent.putExtra(Intent.EXTRA_TEXT, url); 
     shareIntent.setType("text/plain"); 

     PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, shareIntent, PendingIntent.FLAG_UPDATE_CURRENT); 

     builder.addToolbarItem(TOOLBAR_SHARE_ITEM_ID, icon, label, pendingIntent); 

    } 

    /* Adds a default share item to the menu */ 
    private static void addShareMenuItem(CustomTabsIntent.Builder builder) { 
     builder.addDefaultShareMenuItem(); 
    } 

    /* Adds a copy item to the menu */ 
    private static void addCopyMenuItem(Context context, CustomTabsIntent.Builder builder) { 
     String label = "Copy"; 
     Intent intent = new Intent(context, CopyBroadcastReceiver.class); 
     PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

     builder.addMenuItem(label, pendingIntent); 
    } 

    public static class CopyBroadcastReceiver extends BroadcastReceiver { 

     @Override 
     public void onReceive(Context context, Intent intent) { 
      String url = intent.getDataString(); 

      ClipboardManager clipboardManager = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE); 
      ClipData data = ClipData.newPlainText("Link", url); 
      clipboardManager.setPrimaryClip(data); 

      Toast.makeText(context, "Copied " + url, Toast.LENGTH_SHORT).show(); 
     } 
    } 
} 

Nie zapomnij dodać zależności do app/build.gradle

dependencies { 
    ... 
    compile 'com.android.support:customtabs:25.2.0' 
} 

i zarejestrować BroadcastReceiver w AndroidManifest.xml

<application> 
    ... 
    <receiver android:name=".CustomTabs$CopyBroadcastReceiver" /> 
</application>
