設置列表視圖只有一行差異

Question

我想讓我的listview只有一行imageview。這裏是我的適配器：

public class ListAdapter extends BaseAdapter { 

private Context activity; 
private ArrayList<HashMap<String, String>> data; 
private static LayoutInflater inflater=null; 

public ListAdapter(Context a, ArrayList<HashMap<String, String>> d) { 
    activity = a; 
    data=d; 
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
} 

public int getCount() { 
    return data.size(); 
} 

public Object getItem(int position) { 
    return data.get(position); 
} 

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

public View getView(int position, View convertView, ViewGroup parent) { 
    View vi=convertView; 
    if(convertView==null) 
     vi = inflater.inflate(R.layout.listview, null); 
    TextView subject = (TextView)vi.findViewById(R.id.subject); 
    TextView added = (TextView)vi.findViewById(R.id.added); 
    TextView permalink = (TextView)vi.findViewById(R.id.permalink); 

    HashMap<String, String> map = new HashMap<String, String>(); 
    map = data.get(position); 

    //Setting all values in listview 
    subject.setText(map.get(ViewPagerAdapter.KEY_NEWS_SUBJECT)); 
    added.setText(map.get(ViewPagerAdapter.KEY_NEWS_LAPSE)); 
    permalink.setText(map.get(ViewPagerAdapter.KEY_NEWS_PERMA)); 
    return vi; 
} 

}

當前佈局有幾個TextView的，但唯一的行可以說我修復4號，僅顯示ImageView的。我應該怎麼做？

首先在自定義佈局中添加一個ImageView。
裏面你public View getView(int position, View convertView, ViewGroup parent)方法添加以下內容：

ImageView image = (ImageView)vi.findViewById(R.id.imageview); 
    if(position == 0){ // here I suppose you want it display on the first row 
     image.setVisibility(View.Visible); 
    } 
    else{ 
     image.setVisibility(View.GONE); 
    } 

附註：我建議你使用getView時使用ViewHolder（）;
