我下面的代碼已經用於隱藏應用程序圖標編程Android的隱藏/取消隱藏應用程序圖標編程
try{
PackageManager p = getPackageManager();
p.setComponentEnabledSetting(getComponentName(), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
}catch (Exception e) {
e.printStackTrace();
}
現在，我想使圖標可見編程
只需使用下面的代碼。
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);
請注意，圖標可能不會消失，直到下一次重新啓動。使用下面的代碼
隱藏應用程序的圖標：
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);
這裏是如何帶回了應用程序的圖標。
PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class);
p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
你好，你的代碼工作完美，但我有一個棘手的事情去做。隱藏圖標後，如果用戶撥打＃007等特定號碼，我想啓動應用程序。我已經實現了傳出呼叫接收器和匹配號碼我試圖開始我的主要活動，但它給我ActivityNotFoundException。你能幫助我，如果你有任何想法.. – Scorpion
@Scorpion是的，你是正確的，將摧毀你的活動，你不能訪問該活動。因爲你需要用另一種方式。 – CoronaPintu
你可以建議我該怎麼做？我得到了：我的代碼的startActivity行上的java.lang.NullPointerException – Scorpion
要隱藏圖標使用此：
PackageManager p = getPackageManager();
ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class);
p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
，並取消隱藏圖標：
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： 這在某種程度上棘手的，如果你需要做的主要活動東西隱藏您的應用。你將面臨一個ActivityNotFoundException。爲了使其工作，您應該在做任何事情之前取消隱藏圖標，然後在完成後再次隱藏它。
簡單的步驟：在這裏獲得
2，取消隱藏圖標
3推出的主要活動
4 - 做你的事情上的主要活動
5隱藏圖標再次
