主屏幕快捷方式不会添加

Question

我正在尝试以编程方式在主屏幕上添加短片，但它不起作用。该代码适用于奥利奥及以上，但不适用于奥利奥以下。

public void addShortcutToHomeScreen() {

        if (ShortcutManagerCompat.isRequestPinShortcutSupported(this)) {

            ShortcutInfoCompat shortcutInfo = new ShortcutInfoCompat.Builder(this, "#1")
                    .setIntent(new Intent(this, ActivityMemes.class).setAction(Intent.ACTION_MAIN)) //!!! intent's action must be set on oreo
                    .setShortLabel("Memeify")
                    .setIcon(IconCompat.createWithResource(this, R.mipmap.ic_launcher))
                    .build();
            ShortcutManagerCompat.requestPinShortcut(this, shortcutInfo, null);

        } else {

            Intent shortcutIntent = new Intent(getApplicationContext(),
                    Activity.class);

            shortcutIntent.setAction(Intent.ACTION_MAIN);

            Intent addIntent = new Intent();
            addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
            addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "Name");
            addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
                    Intent.ShortcutIconResource.fromContext(getApplicationContext(),
                            R.mipmap.ic_launcher));

            addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
            addIntent.putExtra("duplicate", false);
            getApplicationContext().sendBroadcast(addIntent);

        }
    }

这是我的清单文件。

<activity
            android:name="com.my.package.Activities.Activity"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <action android:name="android.intent.action.CREATE_SHORTCUT" />

                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>
        </activity>

请告诉我我做错了什么，因为我试图修复它但失败了。还有比这更好的方法吗？如有任何帮助，我们将不胜感激。

您可以在您的应用程序中使用此方法class

public void createShortCut() {

            Intent shortcutintent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
            shortcutintent.putExtra("duplicate", false);
            shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
            Parcelable icon = Intent.ShortcutIconResource.fromContext(getApplicationContext(),
                    R.drawable.logo);
            shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);
            shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(getApplicationContext(), SplashActivity.class));
            sendBroadcast(shortcutintent);

        }
    }

并应用此权限

    <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />

如果您使用的是 Android 8+，则不能再使用广播，您必须使用 ShortcutManager ： https://developer.android.com/about/versions/oreo/android-8.0-changes#as

Android 8.0 (API level 26) includes the following changes to app shortcuts:

The com.android.launcher.action.INSTALL_SHORTCUT broadcast no longer has any effect on your app, because it is now a private, implicit broadcast. Instead, you should create an app shortcut by using the requestPinShortcut() method from the ShortcutManager class.

The ACTION_CREATE_SHORTCUT intent can now create app shortcuts that you manage using the ShortcutManager class. This intent can also create legacy launcher shortcuts that don't interact with ShortcutManager. Previously, this intent could create only legacy launcher shortcuts.

Shortcuts created using requestPinShortcut() and shortcuts created in an activity that handles the ACTION_CREATE_SHORTCUT intent are now fully-fledged app shortcuts. As a result, apps can now update them using the methods in ShortcutManager.

Legacy shortcuts retain their functionality from previous versions of Android, but you must convert them to app shortcuts manually in your app. To learn more about changes to app shortcuts, see the Pinning Shortcuts and Widgets feature guide.
