如何在expandableListView中的第一列旁边获得第二列？

Question

我的应用程序中有一个基本的（有效的）expandableListView，其中包含2个组和每个组内的2个孩子（以我的人名）。

现在，我想在姓名旁边第二列，其中包含该人的电话号码。最终，我想在包含电话号码的第二列上建立到电话的自动链接。

希望我能得到帮助。

我想存档的示例

[在此处输入图片描述] [1]

我的ExpendableListViewAdapter

public class ExpandableListViewAdapter extends BaseExpandableListAdapter {

    String[] groupNames = {“Group 1", “Group 2”};

    String[][] childNames = {

            // Group 1
            {“Name 1”, “Name 2”},

            // Group 2
            {“Name 1”, “Name 2”},

    };

    Context context;

    public ExpandableListViewAdapter(Context context) {

        this.context = context;
    }

    @Override
    public int getGroupCount() {
        return groupNames.length;
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        return childNames[groupPosition].length;
    }

    @Override
    public Object getGroup(int groupPosition) {
        return groupNames[groupPosition];
    }

    @Override
    public Object getChild(int groupPosition, int childPosition) {
        return childNames[groupPosition][childPosition];
    }

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

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

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

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded, View view, ViewGroup parent) {

        TextView txtView = new TextView(context);
        txtView.setText(groupNames[groupPosition]);
        txtView.setPadding(150, 40, 0, 40);
        txtView.setTextColor(Color.rgb(2, 20, 94));
        txtView.setTextSize(23);
        return txtView;
    }

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

        final TextView txtView = new TextView(context);
        txtView.setText(childNames[groupPosition][childPosition]);
        txtView.setPadding(100, 40, 0, 40);
        txtView.setTextColor(Color.rgb(2, 20, 94));
        txtView.setTextSize(18);

        txtView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(context, txtView.getText().toString(), Toast.LENGTH_SHORT).show();
            }
        });

        return txtView;

    }

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