关于ExpandableListView嵌套ExpandableListView的问题

[android_Y]

我在ExpandableListView中嵌套了ExpandableListView
被嵌套在子项中的ExpandableListView无法打开
只有子项那么高无法变高
主类

package R.M.activity;

import java.io.File;
import java.util.ArrayList;
import java.util.List;
import R.M.R;
import R.M.adapter.rmAdapter;
import android.app.ExpandableListActivity;
import android.os.Bundle;

public class MainActivity extends ExpandableListActivity {
    /** Called when the activity is first created. */
    String rootpath = "/";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        File root = new File(rootpath);
        File[] files = root.listFiles();
        List<File[]> child = new ArrayList<File[]>();
        for(File file : files) {
            child.add(file.listFiles());
        }
        setListAdapter(new rmAdapter(files, child, this));
    }
}

适配器

package R.M.adapter;

import java.io.File;
import java.util.ArrayList;
import java.util.List;
import R.M.R;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseExpandableListAdapter;
import android.widget.ExpandableListView;
import android.widget.TextView;

public class rmAdapter extends BaseExpandableListAdapter {
    File[] parentfiles = new File[1];

主类XML

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

子项为ExpandableListView的XML
