試試這個
您的列表項行XML會是這樣 Abc.xml

<?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="wrap_content" 
    android:orientation="vertical" 
    android:background="@android:color/darker_gray"> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="horizontal" 
     android:layout_margin="5dp"> 

     <TextView 
      android:id="@+id/textView1" 
      android:layout_width="match_parent" 
      android:layout_height="80dp" 
      android:layout_weight="1" 
      android:gravity="center" 
      android:text="Name1" 
      android:textSize="18sp" 
      android:background="@android:color/white" 
      android:layout_margin="5dp"/> 

     <TextView 
      android:id="@+id/textView2" 
      android:layout_width="match_parent" 
      android:layout_height="80dp" 
      android:layout_weight="1" 
      android:gravity="center" 
      android:text="Name2" 
      android:textSize="18sp" 
      android:layout_margin="5dp" 
      android:background="@android:color/white"/> 

     <TextView 
      android:id="@+id/textView3" 
      android:layout_width="match_parent" 
      android:layout_height="80dp" 
      android:layout_weight="1" 
      android:gravity="center" 
      android:text="Name3" 
      android:textSize="18sp" 
      android:layout_margin="5dp" 
      android:background="@android:color/white"/> 


    </LinearLayout> 


</LinearLayout> 

而且CustomAdapter的名單會是這樣

public class Custom_Adapter_Products extends BaseAdapter { 
    Context context; 
    String[] list = {"AAA","AAA","AAA","AAA","AAA","","AAA", "AAA","AAA"}; 

    public Custom_Adapter_Products(Context context){ 
     this.context = context; 
    } 

    @Override 
    public int getCount() { 
     return (list.length/3); 
    } 

    @Override 
    public Object getItem(int position) { 

     return null; 
    } 

    @Override 
    public long getItemId(int position) { 

     return position; 
    } 

    @Override 
    public View getView(int pos, View convertView, ViewGroup parent) { 
     try{ 
      int position = (pos*3); 
      ViewHolder holder; 
      LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      if (convertView == null) 
      { 
       convertView = vi.inflate(R.layout.abc, null); 
       holder = createViewHolder(convertView); 
       convertView.setTag(holder); 
      } 
      else 
      { 
       holder = (ViewHolder) convertView.getTag(); 
      } 


      if(!list[position].equals("")){ 
       holder.textView1.setText(list[position]); 
       holder.textView1.setVisibility(View.VISIBLE); 
      } 
      else{ 
       holder.textView1.setVisibility(View.GONE); 
      } 

      if(!list[position+1].equals("")){ 
       holder.textView2.setText(list[position]); 
       holder.textView2.setVisibility(View.VISIBLE); 
      } 
      else{ 
       holder.textView2.setVisibility(View.GONE); 
      } 

      if(!list[position+2].equals("")){ 
       holder.textView3.setText(list[position]); 
       holder.textView3.setVisibility(View.VISIBLE); 
      } 
      else{ 
       holder.textView3.setVisibility(View.GONE); 
      } 

     }catch (Exception e){ 
      e.printStackTrace(); 
     } 
     return convertView; 
    } 


    private static class ViewHolder 
    { 
     public TextView textView1; 
     public TextView textView2; 
     public TextView textView3; 
    } 

    private ViewHolder createViewHolder(View v) { 
     ViewHolder holder = new ViewHolder(); 
     try{ 
      holder.textView1 = (TextView) v.findViewById(R.id.textView1); 
      holder.textView2 = (TextView) v.findViewById(R.id.textView2); 
      holder.textView3 = (TextView) v.findViewById(R.id.textView3); 
     }catch (Exception e) { 
      // TODO: handle exception 
      e.printStackTrace(); 
     } 
     return holder; 
    } 
}
