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

@Override
public 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~~~
