Android以编程方式隐藏/取消隐藏应用程序图标

Question

我使用下面的代码以编程方式隐藏应用程序图标

try{
    PackageManager p = getPackageManager();
    p.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
}catch (Exception e) {
    e.printStackTrace();
}

现在我想以编程方式使图标可见

Answer 1

使用以下代码隐藏应用程序的图标:

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); // activity which is first time open in manifiest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

这是恢复应用图标的方法。

PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

重要修改:

根据docs ，从 Android Q (API 29) 开始，所有应用图标都将在启动器中可见，除非:

As of Android Q, at least one of the app's activities or synthesized activities appears in the returned list unless the app satisfies at least one of the following conditions:

• The app is a system app.
• The app doesn't request any permissions.
• The tag in the app's manifest doesn't contain any child elements that represent app components.

Additionally, the system hides synthesized activities for some or all apps in the following enterprise-related cases:

• If the device is a fully managed device, no synthesized activities for any app appear in the returned list.
• If the current user has a work profile, no synthesized activities for the user's work apps appear in the returned list.
