Question

我最近注意到，当在一些Android应用程序中打开链接时，它们具有相似的外观和感觉以及自定义操作菜单，其中包含＆＃34; Powered by Chrome＆＃34;在自定义菜单下方。在这个中使用了什么组件，还是Chromium WebView？希望我希望将它们添加到我的下一个涉及在应用程序中打开链接的项目中。

是Chrome Custom Tabs。您可以在Google Chrome here中看到示例代码。

尝试以下util类：

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();
        }
    }
}

不要忘记将依赖项添加到app/build.gradle

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

并在BroadcastReceiver

中注册AndroidManifest.xml

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

这是动画xml：

slide_in_left.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="100%p" android:toXDelta="0%p"
    android:duration="@android:integer/config_longAnimTime"
    android:interpolator="@android:anim/overshoot_interpolator" />

slide_in_right.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="-100%p" android:toXDelta="0%p"
    android:duration="@android:integer/config_longAnimTime"
    android:interpolator="@android:anim/overshoot_interpolator" />

slide_out_left.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="0" android:toXDelta="-100%p"
    android:duration="@android:integer/config_longAnimTime"
    android:interpolator="@android:anim/overshoot_interpolator" />

slide_out_right.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="0" android:toXDelta="100%p"
    android:duration="@android:integer/config_longAnimTime"
    android:interpolator="@android:anim/overshoot_interpolator" />
