所以我有以下代码
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String selectedItem = parent.getItemAtPosition(position).toString();
switch (selectedItem) {
case "Lowest Price":// handle...
break;
case "Price": // handle...
break;
default: break;
}
adapter.notifyDataSetChanged();
}
但是我已经在字符串文件中填充了适配器的字符串。
有没有办法从父级或视图中获取id,以便我可以执行以下操作:
switch(id)
case R.resource.my_string
答案 0 :(得分:0)
如果你在string.xml中使用String数组,那么
<array name="price_type">
<item>Lowest Price</item>
<item>Price</item>
</array>
你可以直接从数组中获取值,
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
final String[] priceValues = getResources().getStringArray(R.array.price_type);
String selectedItem = priceValues[position];
// if you want to use more manipulation based on the item you can use the position of the value.
adapter.notifyDataSetChanged();
}
