ListView可重复背景创建空白

Question

我正在尝试在listview中创建具有可重复背景的应用程序，但是我在可重复图像之间的空白时遇到了一些麻烦。为什么是这样？我该如何解决这个问题？

是否有其他方法可以创建可重复的背景？

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>
