刷新expandablelistview的整個父項

Question

我無法在expandablelistview中使用自定義佈局來工作，只需點擊兒童孩子即可刷新。

在該示例中，您具有MyExpandableListAdapter - > getChildView方法，其中子代充滿自定義佈局R.layout.list_out_item（什麼是文本瀏覽和按鈕）。

現在我想要的是，如果我點擊一個按鈕，該子視圖的父級更新。我怎樣才能做到這一點？我正在考慮刷新父母和孩子，因爲崩潰迫使更新，但也歡迎其他解決方案。

    ExpandableListAdapter mAdapter; 

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

     // Set up our adapter 
     mAdapter = new MyExpandableListAdapter(); 
     setListAdapter(mAdapter); 

    }

public class MyExpandableListAdapter extends BaseExpandableListAdapter { 
    private Map<Ability, Integer> abilityMods; 
    private List<Skill> skills = SkillList(); 

    private List<Skill> SkillList() { 
     List<Skill> skills = new Vector<Skill>(); 

     abilityMods = Player.getAbilityModifier(); 

     skills.add(new Skill(abilityMods, "Appraise", 2, Ability.Dex, 2)); 
     skills.add(new Skill(abilityMods, "Autohypnosis", 0, Ability.Int, 
       -7));

參見this鏈接定製BaseExpandableListViewAdapter。使用List<View>存儲父視圖，當點擊btn時，獲取父視圖並操作視圖。
