android - 无法触发在 ListPreference 中选择项目的操作

Question

我的其中一个设置页面中有一个列表首选项。只要选择列表中的一个值，我就想执行一个操作。 However the onClick listener is not getting called when an item is selected.单击列表名称时会调用它。以下是相同的相关代码:

    @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    public static class AAFlows extends PreferenceFragment implements Preference.OnPreferenceClickListener {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.pref_flows);
            setHasOptionsMenu(true);

            // Bind the summaries of EditText/List/Dialog/Ringtone preferences
            // to their values. When their values change, their summaries are
            // updated to reflect the new value, per the Android Design
            // guidelines.
            ListPreference flows = (ListPreference) findPreference(getString(R.string.pref_key_flows));
            flows.setOnPreferenceClickListener(this);
            }


        @Override
        public boolean onPreferenceClick(Preference preference) {
            ListPreference flows1 = (ListPreference) findPreference(getString(R.string.pref_key_flows));

            Log.d("TestingOutside2",flows1.getValue());
            return true;
        }
    }

如何在选择列表中的任何值时触发操作？

你可以试试onSharedPreferenceChanged:

Called when a shared preference is changed, added, or removed. This may be called > even if a preference is set to its existing value.
