Display Snackbar in Präferenz Frage

Ich möchte eine grundlegende Snackbar zu meiner Anwendung hinzufügen, aber ich habe einen Fehler erhalten, dass ich nicht herausfinden konnte warum. Ich denke, das Problem ist getView(), kann sein, dass ich getListView() verwenden muss, aber ich bin in einem statischen Kontext, also wie?Display Snackbar in Präferenz Frage

Hier ist mein Java-Code:

public class SettingsFragment extends PreferenceActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     // Display the fragment as the main content. 
     getFragmentManager().beginTransaction().replace(android.R.id.content, 
       new PrefsFragment()).commit(); 
     ActionBar bar = getActionBar(); 
     bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#4CAF50"))); 

    } 


    public static class PrefsFragment extends PreferenceFragment { 

     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 

      // Load the preferences from an XML resource 
      addPreferencesFromResource(R.xml.settings); 

      Preference save_database = findPreference("savedatabase"); 
      save_database.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() 
      { 
       public boolean onPreferenceClick(Preference pref) 
       { 
        Data.bdd.Save_database(getActivity(),getView()); 
        return true; 
       } 
      }); 



      final CheckBoxPreference checkboxPref = (CheckBoxPreference) getPreferenceManager().findPreference("checkbox_always_on"); 
      checkboxPref. 
        setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() { 

         public boolean onPreferenceChange(Preference preference, Object newValue) { 
          if (newValue.toString().equals("true")) { 

           Screen.screen_on(getActivity()); 
           Snackbar.make(getListView(),"Auto-extinction de l'écran désactivé",Snackbar.LENGTH_SHORT); 

          } else { 
           Screen.screen_off(getActivity()); 
           Snackbar.make(getView(),"Auto-extinction de l'écran activé",Snackbar.LENGTH_SHORT); 
          } 
          return true; 
         } 
        }); 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
      View view = super.onCreateView(inflater, container, savedInstanceState); 
      view.setBackgroundColor(getResources().getColor(R.color.green_800)); 

      return view; 
     } 
    }

können Sie nur Stil hier einfügen! Welche Version von App compact verwenden Sie? –

@MilindVyas Sie sprechen über welchen Stil? Für AppCompact: Kompilieren Sie 'com.android.support:appcompat-v7:23.0.0' – filol

+0

, ersetzen Sie PreferenceActivity einfach durch AppCompactActivity. –

Also mit Hilfe von @ YasinKaçmaz fand ich die Antwort auf mein Problem. Hier ist mein Code

public class SettingsFragment extends AppCompatActivity { 

static CoordinatorLayout coordinatorLayout; 
Activity thisActivity=this; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     SnackbarShow.showSnackbar(thisActivity); 

     // Display the fragment as the main content. 
     getFragmentManager().beginTransaction().replace(android.R.id.content, 
       new PrefsFragment()).commit(); 
     ActionBar bar = getSupportActionBar(); 
     bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#4CAF50"))); 


    } 

    public static class PrefsFragment extends PreferenceFragment { 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 

      addPreferencesFromResource(R.xml.settings); 


      Preference save_database = findPreference("savedatabase"); 
      save_database.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() 
      { 
       public boolean onPreferenceClick(Preference pref) 
       { 
        Data.bdd.Save_database(getActivity(),getView()); 
        return true; 
       } 
      }); 


      final CheckBoxPreference checkboxPref = (CheckBoxPreference) getPreferenceManager().findPreference("checkbox_always_on"); 
      checkboxPref. 
        setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() { 

         public boolean onPreferenceChange(Preference preference, Object newValue) { 
          if (newValue.toString().equals("true")) { 
           Screen.screen_on(getActivity()); 
           showSnackbar(getView()); 
          } else { 
           Screen.screen_off(getActivity()); 
           showSnackbar(getView()); 
          } 
          return true; 
         } 
        }); 
     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
      View view = super.onCreateView(inflater, container, savedInstanceState); 

      view.setBackgroundColor(getResources().getColor(R.color.green_800)); 

      return view; 
     } 


     public static void showSnackbar(View view) { 
      Snackbar snackbar = Snackbar 
        .make(view, "There is one text", Snackbar.LENGTH_LONG) 
        .setAction("Action Text", new View.OnClickListener() { 
         @Override 
         public void onClick(View view) { 
          Log.v("snackbar","yoo clicked action"); 
         } 
        });

Ich habe diesen Code in meinem Utils, können Sie versuchen:

public static void showSnackbar(final Activity activity) { 
    Snackbar snackbar = Snackbar 
    .make(activity.findViewById(android.R.id.content), "There is one text", Snackbar.LENGTH_LONG) 
    .setAction("Action Text", new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Log.v("snackbar","yoo clicked action"); 
      } 
      }); 

    // Changing message text color 
    snackbar.setActionTextColor(Color.RED); 

    // Changing action button text color 
    View sbView = snackbar.getView(); 
    TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text); 
    textView.setTextColor(Color.YELLOW); 

    snackbar.show(); 
}

Ich habe den gleichen Fehler – filol

In einer anderen Aktivität ist es Arbeit. Wenn ich einen CoordinatorLaoyout hinzufüge, bekam ich 'android.view.InfllateException: Binär XML-Dateizeile # 2: Fehler beim Aufblasen der Klasse LinearLayout' – filol

Ich sah dein Beispiel des Layouts, aber ich verstehe nicht ganz, wie ich es in meinen Code integrieren kann. So was? EDIT: Sorry der Code ist zu lang, siehe hier: http://pastebin.com/ZVQf0820 ' – filol

Gemäß der Dokumentation - https://developer.android.com/reference/android/support/design/widget/Snackbar.html#make(android.view.View,%20java.lang.CharSequence,%20int)

Sie übergeordnete Ansicht müssen, die es zu werden Pässe() -Methode als ein erster Parameter, Suchen Sie in der Layoutdatei Ihres Fragments nach der übergeordneten Ansicht, z. B. RelativeLayout oder LinearLayout. Rufen Sie die XML-Referenz derselben mit der Methode view.findViewById() ab. Und übergeben Sie das Objekt der übergeordneten Ansicht als ersten Parameter. Hoffe es wird helfen!
