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);
