的ListView一個ListView的項目裏面，適配器務必在位置0

Question

您好花花公子我有一個ListView項內的ListView：

<Button 
    android:id="@+id/button_comments_open" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center_horizontal" 
    android:text="Comments" 

    /> 

<ListView 
    android:id="@+id/post_comment_listview" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 


    > 
</ListView> 

內：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 

<ListView 
    android:id="@+id/post_fragment_listview" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_marginBottom="10dp" 
    android:layout_marginLeft="10dp" 
    android:layout_marginRight="10dp" 
    android:layout_marginTop="10dp" > 
</ListView> 

</LinearLayout> 

但內部的ListView的適配器（項目）總是在位置0：

public class PostsCommentsAdapter extends BaseAdapter { 


int ITEM_TEXT_TYPE = 0; 
int ITEM_IMAGE_TYPE = 1; 
LayoutInflater mLayoutInflater; 

Context mContext; 

public PostsCommentsAdapter(Context context, int layout, Cursor c, String[] from, 
     int[] to,SparseArray<String> list ,int flags) { 
    super(); 

    this.mContext = context; 
    this.list = list; 



    mLayoutInflater = (LayoutInflater) 
mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
} 


@Override 
public int getCount() { 
    System.out.println("List Size : "+list.size()); 
    return list.size(); 
} 

@Override 
public int getViewTypeCount() { 
    return 2; 
} 

@Override 
    public int getItemViewType(int position) { 

    System.out.println("Getting for Position : "+position+" is The : 
"+list.get(position)); 

// mCursor.moveToPosition(commentsidslist.get(position)); 
    System.out.println("To Get Type"+list.get(position)); 
    String type = (list.get(position).split("\\&&DETAIL&&"))[1]; 
    int chooser = -1; 

    //  1 = like 2 = dislike 3 = comment 4 = imageurl 

    switch (type) { 
    case "C":  
     chooser = 0; 
     break; 
    case "P": 
     chooser = 1; 
     break; 

    default: 
     break; 
    } 

System.out.println("TYPE "+type); 

    return chooser; 

} 

@Override 
public Object getItem(int position) { 
    return list.get(position); 
} 

@Override 
public long getItemId(int position) { 
    return list.get(position).hashCode(); 
} 



@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 

    ViewHolder holder = null; 

    int Demand = getItemViewType(position); 
    System.out.println("Demand :"+Demand); 
    if (convertView == null || convertView.getTag() == null) { 

     holder = new ViewHolder(); 

    System.out.println("ConvertView null"); 

     switch (Demand) { 
     case 0: 
      //text 
      convertView = mLayoutInflater.inflate(R.layout.post_list_row_text, null); 
      holder.tv = (TextView)convertView.findViewById(R.id.post_detail_row_text); 
      holder.like = (Button)convertView.findViewById(R.id.button_comment_like); 
      holder.dislike = 
(Button)convertView.findViewById(R.id.button_comment_dislike); 

      break; 
     case 1: 
      //picture 
      convertView = mLayoutInflater.inflate(R.layout.post_list_row_picture, 
null); 
      holder.iv = 
(ImageView)convertView.findViewById(R.id.comment_row_imageview); 
      holder.like = (Button)convertView.findViewById(R.id.button_comment_like); 
      holder.dislike = 
(Button)convertView.findViewById(R.id.button_comment_dislike); 

      break; 

     default: 
      break; 
     } 




      convertView.setTag(holder); 


      }else { 
       holder = (ViewHolder) convertView.getTag(); 
      } 


     switch (Demand) { 
     case 0: 

      holder.tv.setText((list.get(position).split("\\&&DETAIL&&"))[3]); 
      holder.like.setText("0 For Now"); 
      //if 
      holder.like.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 

       } 
      }); 

      break; 

     case 1: 

      Picasso.with(mContext).load(((list.get(position).split("\\&&DETAIL&&")) 
[3])).resize(150, 150).into(holder.iv); 
      holder.like.setText("0 For Now"); 
      //if 
      holder.like.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        // TODO Auto-generated method stub 

       } 
      }); 

      break; 

     default: 
      break; 
     } 




    System.out.println("Post Row Detail Item : "+((list.get(position)))); 
    return convertView; 
} 

我已經嘗試幾乎所有的東西，但它只是沒有工作，我的問題在哪裏G你呢？！

你應該使用可擴展的listView。獲取教程在這裏：http://androidexample.com/Custom_Expandable_ListView_Tutorial
