Android以编程方式隐藏/取消隐藏应用程序图标

我已经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，我想使用以下代码以编程方式使图标可见

隐藏应用程序的图标：

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

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);

据介绍，自Android Q（API 29）起，无论发生什么情况，所有应用程序图标都将在启动器中可见，除非：

截至Android Q，至少有一个应用程序的活动或合成 活动显示在返回的列表中，除非应用满足以下条件： 至少满足以下条件之一：

• 该应用程序是一个系统应用程序
• 应用程序未请求任何权限
• 应用程序清单中的标记不包含任何表示应用程序组件的子元素

此外，系统隐藏部分或全部的合成活动 以下企业相关案例中的应用程序：

• 如果设备是完全受管理的设备，则返回的列表中不会显示任何应用程序的合成活动
• 如果当前用户具有工作配置文件，则返回的列表中不会显示用户工作应用程序的合成活动

要隐藏图标，请使用以下命令：

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

要取消隐藏图标，请执行以下操作：

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

重要提示： 当应用程序中的主要活动被隐藏时，如果您需要对其执行某些操作，这会有点棘手。您将面临一个

ActivityNotFoundException

。要使其工作，您应该在对主要活动执行任何操作之前取消隐藏图标，并在完成后再次将其隐藏。
简单步骤： 这里接收到一个呼叫
2-取消隐藏图标
3-启动主要活动
4-在主要活动中做你的事情

谢谢

从您可以使用的启动器隐藏应用程序图标的最佳方法

在你的活动清单中

  <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LEANBACK_LAUNCHER"/>
        </intent-filter>
    </activity>

自Android Q（API 29）起，不再支持此功能。详细信息也已添加到。您的应用程序图标将可见，除非它满足以下条件之一：

• 该应用程序是一个系统应用程序
• 应用程序未请求任何权限
• 应用程序清单中的标记不包含任何 表示应用程序组件

---

这是我到目前为止所发现的，不幸的是，这不是对原始问题的回答，只是备选方案

这是第一个选项，但是如果你的应用程序需要权限，并且不再有用（至少在Android 10中是这样），正如@CoronaPintu在这里提到的，这个方法可以工作，但有很多限制

private void hideIcon(Context context, Class activityToHide) {
    PackageManager packageManager = getPackageManager();
    ComponentName componentName = new ComponentName(context, activityToHide);
    packageManager.setComponentEnabledSetting(
        componentName,
        PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
        PackageManager.DONT_KILL_APP);
}

使用上述相同方法加上adb命令，即使您的应用程序需要此替代方案的许可，但您必须访问设备并连接到pc，然后运行此命令

要隐藏：

$adb外壳设置将全局显示\隐藏\图标\应用程序\启用0

显示：

$adb外壳设置将全局显示\隐藏\图标\应用程序\启用1

以防万一，您无法从应用程序运行此命令

Runtime.getRuntime().exec("dpm set-device-owner my.package.name/.DevAdminReceiver");    

另一个选项是DevicePolicyManager

private void hideIcon(Context context, Class activityToHide) {
    ComponentName componentName = new ComponentName(context, activityToHide);
        DevicePolicyManager devicePolicyManager = (DevicePolicyManager) getSystemService(getApplicationContext().DEVICE_POLICY_SERVICE);
        devicePolicyManager.setApplicationHidden(componentName, "your.package.name.here", true);
}

这种方法是有效的，但我们也有一些限制，您需要 启用设备所有者模式，您可以找到更多信息

要启用此模式，必须运行此adb命令

adb shell dpm set-device-owner my.package.name/.DevAdminReceiver

但是，您可以从应用程序中执行此命令

Runtime.getRuntime().exec("dpm set-device-owner my.package.name/.DevAdminReceiver");    

但是，如果手机已经设置了帐户，此方法将失败，并出现下一个错误：

java.lang.IllegalStateException: Not allowed to set the device owner because there are already several users on the device

您好，您的代码工作得很好，但我有一件棘手的事情要做。隐藏图标后，如果用户拨打#007等特定号码，我想启动应用程序。我已经实现了呼出呼叫接收器和号码匹配，我正在尝试开始我的主要活动，但它给了我ActivityNotFoundException。如果你有任何想法，你能帮我吗？@Scorpion是的，你是对的，这会破坏你的活动，你不能访问该活动。为此，你需要使用另一种方法。@Scorpion为此，我进行了大约2天的研发。。是的，现在只要给你一个解决方案，你要隐藏你的mainActivity一旦你隐藏它，活动将不会被找到它的破坏，所以你需要创建相同的另一个活动，如mainActivity2，你需要存储布尔值到SharerPrefRence图标是否隐藏然后你需要打开mainActivity2否则mainActivity。。。请检查您的解决方案是否有效的相同请求。但应用程序图标将继续显示，直到重新启动。有什么解决办法吗@Coronapintu我知道它已经有一段时间没有被问到了，但我认为应该有另一个活动，没有使用launcher意图过滤器定义（因此它不会出现在app launcher中）这将有一个呼出呼叫目的过滤器来启用主活动。这无疑是最好的和干净的解决方案相对于其他以前的解决方案。感谢一款仅适用于电视应用的乳液有什么手动处理的方法吗@艾哈迈德：是的，它工作得很好，但我没有找到任何手动处理的方法你实施了这个吗？请告知。许多人都坚持这一点days@RaRa我正在使用Java代码隐藏图标，但在Android 10上，只有我的代码不起作用。如何打开它？这与一年前发布的代码有何不同？您的建议不应该是对此的评论吗？@弃置购物车我的回答还提供了如何在禁用MainActivity时使用它。当你使用这种方法隐藏你的应用程序时，很可能会得到ActivityNotFoundException，但是没有一个答案没有关于它的详细信息。这就是为什么我将我的答案添加为新的，这样人们就可以看到它。问题是一旦应用程序被隐藏，如何将其取消隐藏。答案的唯一原始部分似乎是一种与问题无关的方法，因为OP不是询问他们在隐藏时试图使用它会出现什么错误，而是询问如何取消隐藏（默认情况下解决错误）。它应该有
