以Android小机器人作为ListView的背景图片，增加ListView的周边距离，分割线透明，效果如图所示：

主要是通过布局文件实现。给出代码实现activity_main.xml：

测试的主Activity MainActivity.java：

package zhangphil.demo;import android.app.Activity;import android.content.Context;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ArrayAdapter;import android.widget.ListView;import android.widget.TextView;public class MainActivity extends Activity {	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);		ListView list = (ListView) findViewById(android.R.id.list);		String[] data = new String[100];		for (int i = 0; i < data.length; i++) {			data[i] = "数据" + i;		}		list.setAdapter(new MyArrayAdapter(this, android.R.layout.simple_list_item_1, data));	}	private class MyArrayAdapter extends ArrayAdapter
     
       {		private String[] data;		private LayoutInflater layoutInflater;		private int resource;		public MyArrayAdapter(Context context, int resource, String[] data) {			super(context, resource);			this.data = data;			this.resource = resource;			this.layoutInflater = LayoutInflater.from(context);		}		@Override		public View getView(int position, View convertView, ViewGroup parent) {			if (convertView == null)				convertView = layoutInflater.inflate(resource, null);			TextView text = (TextView) convertView.findViewById(android.R.id.text1);			text.setText(getItem(position));			convertView.setBackgroundColor(0xff80deea);			// convertView.getBackground().setAlpha(128);			return convertView;		}		@Override		public String getItem(int pos) {			return data[pos];		}		@Override		public int getCount() {			return data.length;		}	}}
