R.string无法解析或不是字段

Question

I am programming a map in android, I follow this tutorial hier ,and I want to add error messages, but the errors are not in R class. The errors, which I mean, are: R.string.invalid_lat_long_used, R.string.service_not_available R.string.no_address_found, R.string.address_found
how can I resolve this problem?

Answer 1

The link that you followed, doesnt says about the changes that you have to make in other resource files.

The reason why you are not able to get R.string.invalid_lat_long_used , R.string.service_not_available etc are because, these are custom strings that are specified by you. So you'll have to declare these strings in a file named Strings.xml manually.

You can see that, there is already a file named Strings.xml in your project. So you'll have to edit the Strings.xml file with all the above mentioned Strings.

According to the docs , values in Strings.xml can be set as follows

<resources>
    <string name="test_text">Test</string>
    <string name="clear_text">Clear</string>
    <string name="wifi_connection">The active connection is wifi.</string>
    <string name="mobile_connection">The active connection is mobile.</string>
    <string name="no_wifi_or_mobile">No wireless or mobile connection.</string>
</resources>

So for your case the Strings.xml file should contain all these Strings too

<string name="invalid_lat_long_used">Invalid Lat Long</string>
<string name="service_not_available ">Service Not Available</string>
<string name="no_address_found">No address found</string>
<string name="address_found">Address found</string>

etc..

Strings.xml file can be found inside res / values /

Answer 2

Add that values inside the Strings.xml file:

<string name="invalid_lat_long_used">Invalid Lat Long Used</string>
<string name="service_not_available ">Service Not Available</string>
<string name="no_address_found">No Address Found</string>
<string name="address_found">Address Found</string>
