问题描述

我有一个应用程序，可让您在主屏幕中创建快捷方式".但是我可以检测快捷方式"是否已经存在，而不必再次创建它. 谢谢.

I have an app that allows you to create "shortcuts" in Home Screen. But can i detect if the "shortcuts" already exist, i didn't have to create it again. Thanks.

推荐答案

我遇到了同样的问题.我认为您不可能告诉它是否存在，但我认为我使用的方法也对您有用.

I was having the same issue. I don't think its possible for you to tell if it's there, but I think what I used will work for you as well.

在添加快捷方式之前，只需将其卸载！

Simply uninstall the shortcut before you add it!

intent.setAction("com.android.launcher.action.UNINSTALL_SHORTCUT");
getApplicationContext().sendBroadcast(intent);

intent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
getApplicationContext().sendBroadcast(intent);

只需确保将以下内容添加到清单文件中即可.

Just make sure you add the following to your manifest file.

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