ListView可重複背景創建空白

Question

我正在嘗試使用listview中的可重複背景製作應用程序，但是我在可重複圖像之間的空格時遇到了一些麻煩。爲什麼是這樣？我該如何解決這個問題？

是否有另一種方法來創建可重複的背景？

public View getView(int position, View convertView, ViewGroup parent) { 
     LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     View row = inflater.inflate(R.layout.event_list, parent, false); 
     List<Events> r = getEvent(); 
     Events e = r.get(position); 

     LoaderImageView image = (LoaderImageView) row.findViewById(R.id.imageView1); 
     TextView tittel = (TextView) row.findViewById(R.id.textView1); 
     TextView ingress = (TextView) row.findViewById(R.id.textView2); 

     tittel.setText(e.getEventName().toString()); 
     ingress.setText(e.getIngress().toString()); 
     image.setImageDrawable(e.getThumbnail().toString()); 



     Resources res = getResources(); 
     BitmapDrawable background = (BitmapDrawable) res.getDrawable(R.drawable.almanakk_bg); 
     background.setTileModeY(TileMode.REPEAT); 

     row.setBackgroundDrawable(background); 




     return row; 
    }

Answer 2

create drawable bg.xml file 

<bitmap xmlns:android="http://schemas.android.com/apk/res/android" 
    android:src="@drawable/back" 
    android:tileMode="repeat" /> 

and in your activitypage .xml write like this 

    <ListView 
     android:id="@+id/mylist" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:backgorund="@drawable/bg" > 
    </ListView>
