今天学习了simpleAdapter简单适配器
简单适配器在适配器中作用很大,例如微信qq的消息列表
simpleadapter的五个参数
data是一个
List<Map<String,Object>> data = new ArrayList<>();
Map<String,Object> map = new HashMap<>();
map.put("icon",R.drawable.apple);
map.put("name","套餐");
map.put("content","卤肉饭套餐");
data.add(map);
String[] from = new String[]{
"icon","name","content"
};
int [] to = new int[]{
R.id.food_image,
R.id.food_name,
R.id.food_content
};
form数组是键值对的String
to数组是布局文件中一一对应的id
android.widget.SimpleAdapter simpleAdapter = new android.widget.SimpleAdapter(this,data,R.layout.food_item,from,to);
