个性化(Style/Theme)之ListView

1)Item分隔栏


只需要在Adapter中Override isEnabled Method, 在getView中设置其他相关的即可。

public class XXXItemAdapter extends BaseAdapter{
	private LayoutInflater minflater;
	private List<CommonViewHolder> list;
	public FinanceListItemAdapter(LayoutInflater inflater, List<CommonViewHolder> list) {
		super();
		this.minflater = inflater;
		this.list = list;
    }

	@Override
	public int getCount() {
		return  this.list.size();
	}

	@Override
	public boolean isEnabled(int position) {
		boolean result = true;
		if(position == 0 || position == 4 || position == 9 ) {
			result = false;
		}
		return result;
	}

	@Override
	public Object getItem(int position) {
		return  position < this.list.size()  ? this.list.get(position) : null;
	}

	@Override
	public long getItemId(int position) {
		return  position < this.list.size() ? this.list.get(position).id :  -1l;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		CommonViewHolder commHolder = null;
		   if(convertView == null) {
			    convertView = minflater.inflate(R.layout.list_common_item, null);
			    commHolder = new CommonViewHolder();
			    commHolder.text= (TextView)convertView.findViewById(R.id.more_item_text);
			    commHolder.sign = (ImageView)convertView.findViewById(R.id.more_item_sign);
			    commHolder.sign.setImageResource(R.drawable.go_next_icon);
			    commHolder.text.setTextColor(Color.BLACK);
			    convertView.setDrawingCacheBackgroundColor(Color.WHITE);
			    convertView.setTag(commHolder);
		   }else {
			   commHolder =  (CommonViewHolder) convertView.getTag();
		   }
		   commHolder.text.setText(this.list.get(position).text.getText());
		   if(position == 0 || position == 4 || position == 9 ) {
			   commHolder.sign.setImageDrawable(null);
			   convertView.setBackgroundColor(Color.GRAY);
		   }
		   return convertView;
	}

}

2)自定义背景(白色＋圆角)

只需要配置XML即可。


four_white_corner_listview_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<selector
    xmlns:android="http://schemas.android.com/apk/res/android">
   
    <item>        
       <shape xmlns:android="http://schemas.android.com/apk/res/android" 
                    android:shape="rectangle"> 
                   <stroke android:width="3dip" android:color="#ffffffff" /> 
                    <solid android:color="#ffffffff" /> 
                    <corners android:bottomRightRadius="6dip" 
                        android:bottomLeftRadius="6dip" 
                        android:topLeftRadius="6dip" 
                        android:topRightRadius="6dip" /> 
                </shape> 
    </item>
    
    
</selector>
