InnerList查看没有滚动

Question

嗨，我在另一个列表视图中创建一个列表视图使用此代码

package com.ltest; 

import android.app.Activity; 
import android.content.Context; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ListView; 
import android.widget.TextView; 

public class LTestActivity extends Activity { 
/** Called when the activity is first created. */ 
String[] str1 = {"one1","two1","three1","four1","five1"}; 
String[] str2 = {"one2","two2","three2","four2","five2"}; 
String[] str3 = {"one3","two3","three3","four3","five3"}; 
String[] str4 = {"one4","two4","three4","four4","five4"}; 
String[] str5 = {"one5","two5","three5","four5","five5"}; 
String[][]str = {str1,str2,str3,str4,str5}; 
String[] ttl = {"A","B","C","D","E"}; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    ListView lv = (ListView)findViewById(R.id.list_main); 
    lv.setAdapter(new EfficientAdapter(this,str,ttl)); 
} 



public class EfficientAdapter extends BaseAdapter { 
    private LayoutInflater mInflater; 
    private String[][] str; 
    private String[] ttl; 
    Context context; 
    public EfficientAdapter(Context context,String[][] str, String[] ttl) { 
     mInflater = LayoutInflater.from(context); 
     this.str = str; 
     this.context = context; 
     this.ttl = ttl; 
    } 

    public int getCount() { 
     return str.length; 
    } 

    public Object getItem(int position) { 
     return position; 
    } 

    public long getItemId(int position) { 
     return position; 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 
     if (convertView == null) { 
      convertView = mInflater.inflate(R.layout.custom_list,null); 
      TextView tv_ttl = (TextView)convertView.findViewById(R.id.text_ttl); 
      ListView InnerList = (ListView) convertView.findViewById(R.id.list); 
      InnerList.setAdapter(new InnerEfficientAdapter(context, str[position])); 
      tv_ttl.setText(ttl[position]); 
     } 
     return convertView; 
    } 

    public class InnerEfficientAdapter extends BaseAdapter { 
     private LayoutInflater mInflater; 
     private String[] str; 

     public InnerEfficientAdapter(Context context,String[] str) { 
      mInflater = LayoutInflater.from(context); 
      this.str = str; 
     } 

     public int getCount() { 
      return str.length; 
     } 

     public Object getItem(int position) { 
      return position; 
     } 

     public long getItemId(int position) { 
      return position; 
     } 

     public View getView(int position, View convertView, ViewGroup parent) { 
      if (convertView == null) { 
       convertView = mInflater.inflate(R.layout.custom_list_second,null); 
       TextView tv = (TextView) convertView.findViewById(R.id.text); 
       tv.setText(str[position]); 
      } 
      return convertView; 
     } 
     } 
    } 

} 

，但我发现，内部列表视图不滚动，任何一个能帮助我吗？ 谢谢; http://i.stack.imgur.com/uKQlZ.png 和图像在这里

您应该使用ExpandableListView。

内部列表不滚动，因为ListView实现了自己的滚动器并拦截所有滚动手势。
