在PreferenceScreen中显示crouton

Question

我使用Crouton库向用户显示警告消息。在这种情况下，我希望在特定的首选项屏幕中显示。我在我的PreferenceActivity中编写了以下代码

但是，Crouton只显示在第一个首选项屏幕上，而不显示在实际触发Crouton的子首选项屏幕上。有什么办法解决这个问题吗？

       findPreference(key.key).setOnPreferenceChangeListener(new OnPreferenceChangeListener()
        {

            @Override
            public boolean onPreferenceChange(Preference preference, Object newValue)
            {
                int count = 0;
                for (ANALYTICS_KEYS key : ANALYTICS_KEYS.values())
                {
                    if (appPreferences.getAnalyticProperty(key))
                    {
                        count++;

                    }
                }

                Crouton crouton = null;
                if (count > 5 && count < 7)
                {
                    Style.Builder style = new Builder(Style.INFO).setConfiguration(new Configuration.Builder().setDuration(Configuration.DURATION_INFINITE).build());

                    crouton = Crouton.makeText(DashAnalyticsPreferenceActivity.this, "More than 5 attributes might not be visible", style.build());

                }
                else if (count > 7)
                {
                    crouton = Crouton.makeText(DashAnalyticsPreferenceActivity.this, "More than 7 attributes are not allowed. Only first 7 will be considered", Style.ALERT);
                }
                else
                    Crouton.cancelAllCroutons();

                if (crouton != null)
                {
                    crouton.show();
                    crouton.setOnClickListener(new View.OnClickListener()
                    {
                        @Override
                        public void onClick(View v)
                        {

                            //Crouton.hide(crouton);
                        }
                    });
                }

                return true;
            }

Crouton被附加到Activites视图。因此，它将只显示在为创建它而传递的Activity中。

如果要在其他Crouton中显示Activity，则必须将相应的Activity传递给它。
