推荐答案

这是什么问题？

解决了preference并设置一个监听器，做烤面包？
事情是这样的例如：

Resolve the preference and set a listener that does the toast? Something like this for example

ListPreference listPreference = findPreference(key);
    listPreference.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
        @Override
        public boolean onPreferenceChange(Preference preference, Object newValue) {
            Toast.makeText(SettingsActivity.this, "second", Toast.LENGTH_LONG).show();
            return true;
        }
    });
