PreferenceFragmentCompat nicht auf First-Touch-Ereignis

Question

Ich habe eine PreferenceFragmentCompat Einstellungen alles funktioniert funktioniert gut, aber ich bemerkte etwas seltsam, klicken Sie auf Einstellungsschaltfläche zum ersten Mal, wenn Präferenz-Bildschirm geladen und ich berühre einige Präferenzen es reagiert nicht auf meine erste Berührung aber Recht, nachdem es funktioniert in der Regel ist dies mein Code

public class SettingsFragment extends PreferenceFragmentCompat implements HomeActivity.Authentication, Preference.OnPreferenceClickListener, SharedPreferences.OnSharedPreferenceChangeListener, ConfirmAlertDialog.OnDialogClickInterface { 
@Override 
public boolean onPreferenceClick(final Preference preference) { 
    final String key = preference.getKey(); 

    switch (key) { 
     case "remove_ads": 
      homeActivity.purchaseRemoveAds(); 
      break; 
     case "hide_icon": 
      try { 
       homeActivity.loadFragment(new HideOptiosTutorial(), getParentFragment().getFragmentManager().beginTransaction()); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
      break; 

     case "key_share_app_link": 
      shareAppFile(); 

      break; 

     case "move_to_sdcard": 

      showMovetoSdDialog(); 

      break; 
     case "button_internal": 

      showMovetoInternalDialog(); 

      break; 
     case "back_up_sdcard": 
      if (isSDCardUnmounted()) { 
       showSDCardMountError(); 
      } else { 

       globalPasswords = getBackupPasswords(); 

       if (!FileUtilis.isSafAllowed(getActivity())) { 
        showSDCardNotAllowedDialog(983); 
        // 
        return false; 
       } 

       if (globalPasswords.size() == 0) { 
        showNoBackupFoundMsg(); 
       } else { 
        showDialogToBackupFromSDCard(); 
       } 
      } 
      break; 
     case "change_password": 
      showChangePinDialog(); 
      break; 

     case "key_rate_us": 
      rateApplication(); 
      break; 
     case "app_link": 
      SavedAlbumsFragment.showAppLockLink(getActivity()); 
      break; 
     case "view_intruders": 
      startActivity(new Intent(homeActivity, ViewIntruders.class)); 
      break; 
     case "theme": 
      showSelectTehmeDialog(); 
      break; 

     case "enter_email": 

      showChangeEmailDialog(); 
      break; 
    } 


    return false; 
} 
@Override 
public void onCreatePreferences(Bundle bundle, String s) { 
    addPreferencesFromResource(R.xml.pref_headers); 
    Log.e("Mateen","onCreatePreferences"); 

    homeActivity = ((HomeActivity) getActivity()); 
    homeActivity.addAuthenticationListner(this); 
    localDatabase = LocalDatabase.getInstance(getActivity()); 
    localPreferences = new LocalPreferences(getActivity()); 

    getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this); 
    LocalBroadcastManager.getInstance(homeActivity).registerReceiver(broadcastReceiver,new IntentFilter("Remove_Is_Purchased")); 

    removeAdsPref=findPreference("remove_ads"); 
    mCategory = (PreferenceCategory)findPreference("cat_remove_ads"); 



    if (localPreferences.IsRemovedAdsPurchased()) 
    { 
     mCategory.removePreference(removeAdsPref); 
     getPreferenceScreen().removePreference(mCategory); 
    } 
    else 
    { 
     removeAdsPref.setOnPreferenceClickListener(this); 
    } 

    findPreference("move_to_sdcard").setOnPreferenceClickListener(this); 
    findPreference("view_intruders").setOnPreferenceClickListener(this); 
    findPreference("button_internal").setOnPreferenceClickListener(this); 
    findPreference("back_up_sdcard").setOnPreferenceClickListener(this); 
    findPreference("change_password").setOnPreferenceClickListener(this); 
    findPreference("key_rate_us").setOnPreferenceClickListener(this); 
    findPreference("app_link").setOnPreferenceClickListener(this); 
    findPreference("hide_icon").setOnPreferenceClickListener(this); 
    findPreference("key_share_app_link").setOnPreferenceClickListener(this); 
    findPreference("listPref_wrong_tries").setOnPreferenceClickListener(this); 
    findPreference("theme").setOnPreferenceClickListener(this); 
    findPreference("enter_email").setOnPreferenceClickListener(this); 




    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { 
     findPreference("key_cam_short").setVisible(false); 
     findPreference("key_vid_short").setVisible(false); 
    } 

    if (!PreferenceManager.getDefaultSharedPreferences(homeActivity).getBoolean("key_intruder_detection",false)) 
    { 
     findPreference("listPref_wrong_tries").setEnabled(false); 
    } 
    if (!Reprint.isHardwarePresent()) { 
     findPreference("key_fingerprint").setEnabled(false); 
    } 

    if (!FileUtilis.isSdcardPresent(getActivity())) { 
     findPreference("move_to_sdcard").setEnabled(false); 
     findPreference("button_internal").setEnabled(false); 
     findPreference("back_up_sdcard").setEnabled(false); 

     // findPreference("change_password").setEnabled(false); 
     findPreference("always_save_to_sdcard").setEnabled(false); 
    } 
    //add xml 

} 

und das ist meine Präferenz xml:

Bitte führen Sie mich, was mache ich falsch? Ist es Unterstützung libs Problem oder mache ich etwas falsch?

Answer 1

i mein Problem xml des

 app:layout_scrollFlags="scroll|enterAlways" 

aus, indem Sie diese Zeile aus meinem Fragment Layout gelöst Bibliothek unterstützen:

<android.support.v7.widget.Toolbar 
    android:id="@+id/toolbar" 
    android:layout_width="match_parent" 
    android:layout_height="?attr/actionBarSize" 
    app:layout_scrollFlags="scroll|enterAlways" 
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light" /> 

jetzt ist es zu hören meine jede verdammte Berührung: D Happy coding

Answer 2

Scheint, Support-Bibliothek-Fehler zu sein. Es funktioniert wie nach der Aktualisierung App gradle Abhängigkeiten zu erwarten 27.0.0

implementation 'com.android.support:appcompat-v7:27.0.0' 
implementation 'com.android.support:preference-v14:27.0.0' 
implementation 'com.android.support:support-v13:27.0.0'
