Android - 在onCreate（）中顯示列表視圖圖像

Question

我想創建一個列表視圖，立即在onCreate（）方法初始化時將圖像只添加到某些字段，我不知道如何做到這一點。

這裏是我的onCreate（）方法的必要組成部分：

((ListView) findViewById(android.R.id.list)).setClickable(true); 
    for(int i=0; i<num_enter; i++){ 
    adapter=new SimpleAdapter(this, listItems, R.layout.custom_row_view,new String[]{"name", "current", "image"}, new int[] {R.id.text1, R.id.text2, R.id.lockImage}); 
    setListAdapter(adapter); 
    HashMap<String,String> temp = new HashMap<String,String>(); 
    temp.put("name", name[i]); 

    SetSql getport = new SetSql(this); 
    getport.open(); 
    int port = getport.getSingleProtect(i); 
    getport.close(); 
    if(port==1){ 
     //THIS IS WHERE I WANT TO SET THE IMAGE 

     temp.put("current", Integer.toString(current[i])); 
    }else{ 
    temp.put("current", Integer.toString(current[i])); 
    } 
    listItems.add(temp); 
    adapter.notifyDataSetChanged(); 
    } 
    }else{ 
     ((ListView) findViewById(android.R.id.list)).setClickable(false); 
     adapter=new SimpleAdapter(this, listItems, R.layout.custom_row_view,new String[]{"name", "current"}, new int[] {R.id.text1, R.id.text2}); 
     setListAdapter(adapter); 
     HashMap<String,String> temp = new HashMap<String,String>(); 
     temp.put("name", "You have no enteries yet!"); 
     temp.put("current", ""); 
     listItems.add(temp); 
     adapter.notifyDataSetChanged(); 
    } 

這裏是我的custome_row_view.xml：

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

<ImageView 
android:layout_height="wrap_content" 
android:layout_width="wrap_content" 
android:id="@+id/lockImage" 
/> 

<TextView android:id="@+id/text1" 
android:textSize="25dp" 
android:textStyle="bold" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
/> 

<TextView android:id="@+id/text2" 
android:textSize="25dp" 
android:layout_marginTop="5dp" 
android:layout_width="wrap_content" 
android:layout_height="fill_parent" 
android:layout_alignParentRight="true"/> 

</RelativeLayout> 

感謝您的幫助！

我認爲你應該製作新的xml文件來記錄你想添加的圖像。您的listView類似category ListView。我有一個理想，你

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    // TODO Auto-generated method stub 
    ViewHolder holder; 
    convertView = null; 
    holder = new ViewHolder(); 
    int port = getport.getSingleProtect(position); 
    if(port==1){ 
    //INFLATE YOUR IMAGE 
     convertView = inflater.inflate(INFLATE_YOUR_IMAGES, null); 
     convertView.setTag(holder); 
     ....................... 




    }else { 
     ................. 
     //INFLATE AS NORMAL 
    } 


    return convertView; 
}
