Android中的ExpandableListView的使用，以及点击时间禁用，并展开group，去掉小三角

刚在项目中做完了一个ExpandableListView的模块，GroupView和childView都是动态获取的，先上一下效果图看一下

上面是大项，下面是小项

1.去掉左边的小箭头，设置下面这个属性即可

lvInsuranceTime.setGroupIndicator(null);

2.设置childView可点击，就是两全险，终身寿险可点击，只要将BaseExpanableAdapter中重写的isChildeSelectable这个返回值改为true即可

@Overridepublic boolean isChildSelectable(int groupPosition, int childPosition) {    return true;}

3.设置group不可点击，也就是上面的大项，不可点击，只需要重写下面的方法，返回true即可

mAdapter = new InsuranceCompanyTypeAdapter(this, OutSizeDatas);lvInsuranceTime.setAdapter(mAdapter);//首次加载全部展开for (int i = 0; i < OutSizeDatas.size(); i++) {    lvInsuranceTime.expandGroup(i);}//让其group不能被点击lvInsuranceTime.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {    @Override    public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {        return true;    }});

当然这个方法，还有一个setOnChildClickListener这个方法，是设置点击child的时候生效，但是切记，一定要将BaseExpanableAdapter中重写的isChildeSelectable这个返回值改为true，否则child的点击事件，是不会生效的

4.下面将Adapter中实现的方法贴出来，有详细的注释

public class InsuranceCompanyTypeAdapter extends BaseExpandableListAdapter{    private  ArrayList<InsuraceCompanyTypeBean.DataEntity> datas;    private Context mContext;//    private ArrayList<InsuraceCompanyTypeBean.DataEntity.SubDictionaryListEntity> bean;//    private final int size;    private static final int TYPE_ITEM = 0;    private static final int TYPE_SEPARATOR = 1;    private static final int TYPE_MAX_COUNT = TYPE_SEPARATOR + 1;    public InsuranceCompanyTypeAdapter(Context context,ArrayList<InsuraceCompanyTypeBean.DataEntity> datas) {        this.datas = datas;        this.mContext = context;//        this.bean = bean;//        size = datas.size() * bean.size();    }//这里是获取group中的数量，也就是寿险一类的数量    @Override    public int getGroupCount() {        return datas.size();    }//这里是获取每个group中child的数量    @Override    public int getChildrenCount(int groupPosition) {        return datas.get(groupPosition).subDictionaryList.size();    }//这里是获取组的当前的item    @Override    public Object getGroup(int groupPosition) {        return datas.get(groupPosition);    }//获取当前组中的child中的item    @Override    public Object getChild(int groupPosition, int childPosition) {        return datas.get(groupPosition).subDictionaryList.get(childPosition);    }//这里一般都是返回这个，不用管    @Override    public long getGroupId(int groupPosition) {        return groupPosition;    }//同上    @Override    public long getChildId(int groupPosition, int childPosition) {        return childPosition;    }//同上    @Override    public boolean hasStableIds() {        return false;    }//注意，这里就是相当于listView中的getView，只不过有两个，一个是group的，一个是child的，这里就不详细说了，会listView，就肯定会这个    @Override    public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {        ViewHolder holder = null;        InsuraceCompanyTypeBean.DataEntity dataEntity = datas.get(groupPosition);        if(convertView == null){            holder = new ViewHolder();            convertView = View.inflate(mContext,R.layout.insurace_type_item,null);            convertView.setTag(holder);        }else{            holder = (ViewHolder) convertView.getTag();        }        holder.tvGroupName = (TextView) convertView.findViewById(R.id.tv_catalog);        holder.tvGroupName.setText(dataEntity.kindText);        return convertView;    }//这里是childView，同上    @Override    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {        ViewHolder holder = null;        InsuraceCompanyTypeBean.DataEntity.SubDictionaryListEntity subDictionaryListEntity = datas.get(groupPosition).subDictionaryList.get(childPosition);        if(convertView == null){            holder = new ViewHolder();            convertView = View.inflate(mContext,R.layout.insurace_type_item2,null);            convertView.setTag(holder);        }else{            holder = (ViewHolder) convertView.getTag();        }        holder.tvChildName = (TextView) convertView.findViewById(R.id.tv_insurance_company_item_name2);        holder.ivChoose = (ImageView) convertView.findViewById(R.id.iv_term_insurance_choosed2);        holder.tvChildName.setText(subDictionaryListEntity.itemText);         if(datas.get(groupPosition).subDictionaryList.get(childPosition).isChoose){                holder.ivChoose.setVisibility(View.VISIBLE);            }else{                holder.ivChoose.setVisibility(View.INVISIBLE);            }        return convertView;    }//这里是设置childItem是否可被点击，true就是可点击，false不可点击    @Override    public boolean isChildSelectable(int groupPosition, int childPosition) {        return true;    }    static  class ViewHolder{        TextView tvGroupName;        TextView tvChildName;        ImageView ivChoose;    }

好了，基本这样就实现了上面的效果了，刚开始也是搞了很久，不过搞定了，哈哈哈哈~~~
