在string.xml文件中与String一起获取值

Question

I have the following in my strings.xml file:

<resources>
   <string name="app_name">My Application</string>
   <string name="title_activity_maps">Map</string>

   <string-array name="city_names">

      <item value="1452">Abbotsford</item>
      <item value="163">Aberdeen</item>
      <item value="821">Acornhoek</item>
      <item value="168">Addo</item>
      <item value="153">Adelaide</item>
      <item value="1433">Aeroton</item>
      <item value="790">Agatha</item>
      <item value="393">Aggeneys</item>
      <item value="867">Agulhas</item>


   </string-array>

I'm using it for an AutoCompleteTextView. My question is, how can I get the value to be printed to the logs after the user searches a city? I'm using this to get the city names, but also wants the value.

cityNames = getResources().getStringArray(R.array.city_names);

Answer 1

This can't be done this way and there is no value attribute in <item> XML tag. What you can do is that you have your string as a pattern and try to parse that pattern in two different values using string manipulation or JSON or any structured data format.

Example:

<string-array name="city_names">
   <item>Abbotsford,1452</item>
   <item>Aberdeen,163</item>
</string-array>

and then parse that using the split on the string to get your two values.
