listview设置不同背景图片并添加selector

前段时间为了实现根据item不同的内容实现不同的背景色google了好久只找到了个隔行换色，通过自定义SimpleAdapter终于实现了此功能，但是定义了selector并没有触发点击效果。今天重新想了一遍终于把这个问题解决了。在自定义的getView里就给每个convertView定义它的背景色和selector。

[代码] 自定义SimpleAdapter

01 public class MySimpleAdapter extends BaseAdapter {
02     private LayoutInflater mInflater;
03
04     private List> dataList;
05
06     public MySimpleAdapter(Context context, List> data) {
07         mInflater = LayoutInflater.from(context);
08         this.dataList = data;
09     }
10
11     @Override
12     public int getCount() {
13         return dataList.size();
14     }
15
16     @Override
17     public Object getItem(int position) {
18         return position;
19     }
20
21     @Override
22     public long getItemId(int position) {
23         return position;
24     }
25
26     @Override
27     public View getView(int position, View convertView, ViewGroup parent) {
28         ViewHolder holder;
29         if (convertView == null) {
30             convertView = mInflater.inflate(R.layout.color_list_item, null);
31             holder = new ViewHolder();
32             holder.blue = (TextView)convertView.findViewById(R.id.blue_item);
33             holder.red = (TextView)convertView.findViewById(R.id.red_item);
34             holder.green = (TextView)convertView.findViewById(R.id.green_item);
35             holder.yellow = (TextView)convertView.findViewById(R.id.yellow_item);
36
37             convertView.setTag(holder);
38
39         } else {
40             holder = (ViewHolder)convertView.getTag();
41
42         }
43         holder.blue.setText((CharSequence)dataList.get(position).get("blue"));
44         holder.red.setText((CharSequence)dataList.get(position).get("red"));
45         holder.green.setText((CharSequence)dataList.get(position).get("green"));
46         holder.yellow.setText((CharSequence)dataList.get(position).get("yellow"));
47         if ("blue".equals(dataList.get(position).get("status").toString())) {
48             convertView.setBackgroundResource(R.drawable.item_chang_blue);
49         } else if("red".equals(dataList.get(position).get("status").toString())) {
50             convertView.setBackgroundResource(R.drawable.item_chang_red);
51         } else if("green".equals(dataList.get(position).get("status").toString())) {
52             convertView.setBackgroundResource(R.drawable.flightinfo_item_chang_green);
53         } else if("yellow".equals(dataList.get(position).get("status").toString())) {
54             convertView.setBackgroundResource(R.drawable.flightinfo_item_chang_yellow);
55         }
56         return convertView;
57     }
58
59     @Override
60     public void notifyDataSetChanged() {
61         super.notifyDataSetChanged();
62     }
63
64     class ViewHolder {
65         TextView blue;
66         TextView red;
67         TextView green;
68         TextView yellow;
69     }
70
71 }

[代码] 选择器item_chang_blue.xml 其他同理

01 "1.0" encoding="utf-8"?>
02
03   xmlns:android="http://schemas.android.com/apk/res/android">
04
05
06
07     android:state_focused="true"
08     android:state_pressed="true"
09  android:drawable= "@drawable/list_item_pressed"/>
10
11
12
13  android:state_focused="false"
14     android:state_pressed="true"
15     android:drawable="@drawable/list_item_pressed" />
16
17
18
19
20  android:state_selected="true"
21     android:drawable="@drawable/list_item_pressed"/>
22
23
24     android:state_focused="true"
25     android:drawable="@drawable/list_item_pressed"/>
26       ​
27     "@drawable/status_blue" />
