Android以编程方式隐藏/取消隐藏应用图标

Question

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

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);

以下是如何恢复应用程序的图标.

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

Answer 2

从启动器中隐藏应用程序图标的最佳方法,您可以<category android:name="android.intent.category.LEANBACK_LAUNCHER"/>在您的清单中使用MainActivity

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

还添加了使用功能

<uses-feature
    android:name="android.software.leanback"
    android:required="true" />

隐藏图标使用此:

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: 如果您需要在应用中隐藏主要活动时执行某些操作,那就太麻烦了.你将面对一个ActivityNotFoundException.为了使它工作,你应该在对主要活动做任何事情之前取消隐藏图标,并在完成后再次隐藏它.
简单的步骤:1 - 在这里收到的电话
2 - 取消隐藏图标
3 - 启动主要活动
4 - 在主要活动上做你的事情
5 - 再次隐藏图标

Answer 4

只需使用以下代码.

 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,在下次重新启动之前,图标可能不会消失.
