Android以编程方式隐藏/取消隐藏应用程序图标
我以编程方式使用下面的代码隐藏应用程序图标
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显示图标
使用以下代码隐藏应用的图标：
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);
这里是如何带回应用程序的图标。
PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
要隐藏图标使用这个：
PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
并取消隐藏图标：
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：在隐藏应用程序时，如果您需要在应用程序的主要活动中执行某些操作，则会有些棘手。 你将面临一个ActivityNotFoundException 。 为了使它工作，你应该在做任何事情之前取消隐藏图标到你的主要活动，并在完成后再次隐藏。
简单的步骤：在这里收到一个电话
2 – 取消隐藏的图标
3发起主要活动
4，在主要活动上做你的事情
再次隐藏图标
只要使用下面的代码。
PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName("com.example.removeicon","com.example.removeicon.LauncherActivity"); p.setComponentEnabledSetting(componentName , PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
请注意，图标可能不会消失，直到下一次重新启动。
