切换偏好需要很长时间才能切换

Question

我的应用程序中有一个android开关，它隐藏了应用程序绘制中的图标。问题是隐藏和启用需要很长时间。

public static class MyPreferenceFragment extends PreferenceFragment {
    @Override
    public void onCreate(final Bundle savedInstanceState) {
        {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.drawer_icon);

            PreferenceManager preferenceManager = getPreferenceManager();
            if (preferenceManager.getSharedPreferences().getBoolean("drawer_icon", true)) {
                PackageManager p = getActivity().getPackageManager();
                ComponentName componentName = new ComponentName(getActivity(), com.dfuse.brokenswitcher.LaunchIconActivity.class);
                p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);
            } else {
                int newState;
                newState = PackageManager.COMPONENT_ENABLED_STATE_DISABLED;
                PackageManager pm = getActivity().getPackageManager();
                pm.setComponentEnabledSetting(new ComponentName(getActivity(), LaunchIconActivity.class), newState, PackageManager.DONT_KILL_APP);
        }


        }
    }

}
