Question

是否可以在可消耗列表视图的每一行中添加不同的子视图XML？

我使用自定义适配器创建了一个可消耗列表视图但我想把它变成以下

可展开列表视图包含数据性别（男性和女性）

如果性别是男性，当我们点击时，子视图应显示男性菜单

如果性别是女性，当我们点击时，子视图应显示女性菜单

如何实现它？

这是我的适配器代码

 package com.example.expandlist;

import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseExpandableListAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class ExpandListAdapter extends BaseExpandableListAdapter {

    private Context context;
    private ArrayList<Group> groups;

    public ExpandListAdapter(Context context, ArrayList<Group> groups) {
        this.context = context;
        this.groups = groups;
    }
@Override
public Object getChild(int groupPosition, int childPosition) {
    ArrayList<Child> chList = groups.get(groupPosition).getItems();
    return chList.get(childPosition);
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return childPosition;
}

@Override
public View getChildView(int groupPosition, int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent) {

    Child child = (Child) getChild(groupPosition, childPosition);
    if (convertView == null) {
        LayoutInflater infalInflater = (LayoutInflater) context
                .getSystemService(context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.child_item, null);
    }
    TextView tv = (TextView) convertView.findViewById(R.id.country_name);
    ImageView iv = (ImageView) convertView.findViewById(R.id.flag);

    tv.setText(child.getName().toString());
    iv.setImageResource(child.getImage());

    return convertView;
}

@Override
public int getChildrenCount(int groupPosition) {
    ArrayList<Child> chList = groups.get(groupPosition).getItems();
    return chList.size();
}

@Override
public Object getGroup(int groupPosition) {
    return groups.get(groupPosition);
}

@Override
public int getGroupCount() {
    return groups.size();
}

@Override
public long getGroupId(int groupPosition) {
    return groupPosition;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded,
        View convertView, ViewGroup parent) {
    Group group = (Group) getGroup(groupPosition);
    if (convertView == null) {
        LayoutInflater inf = (LayoutInflater) context
                .getSystemService(context.LAYOUT_INFLATER_SERVICE);
        convertView = inf.inflate(R.layout.group_item, null);
    }
    TextView tv = (TextView) convertView.findViewById(R.id.group_name);
    tv.setText(group.getName());
    return convertView;
}

@Override
public boolean hasStableIds() {
    return true;
}

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

}

您需要在getChildView方法中为男性和女性创建两种不同的XML布局：

public View getChildView(int groupPosition, int childPosition,
    boolean isLastChild, View convertView, ViewGroup parent) {

    Child child = (Child) getChild(groupPosition, childPosition);
    if (child.getGender==MALE){
        if (convertView == null) {
            LayoutInflater infalInflater = (LayoutInflater) context
                    .getSystemService(context.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.child_item_male, null);
        }
        TextView tv = (TextView) convertView.findViewById(R.id.country_name);
        ImageView iv = (ImageView) convertView.findViewById(R.id.flag);

        tv.setText(child.getName().toString());
        iv.setImageResource(child.getImage());
    }else{
        if (convertView == null) {
            LayoutInflater infalInflater = (LayoutInflater) context
                .getSystemService(context.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.child_item_female, null);
        }
        TextView tv = (TextView) convertView.findViewById(R.id.country_name);
        ImageView iv = (ImageView) convertView.findViewById(R.id.flag);

        tv.setText(child.getName().toString());
        iv.setImageResource(child.getImage());

    return convertView;
}
