Change String-Array in Strings.xml to ArrayList
I'm developing an Android app. I need to convert a string array into an ArrayList. I've read up on this, and all have cases where you add the values to the array in the java file. I have declared the string-array in the strings.xml file. My string-array is here:
<string-array name="Lines">
<item>Red Line</item>
<item>Blue Line</item>
<item>Orange Line</item>
<item>Green Line</item>
<item>Brown Line</item>
<item>Purple Line</item>
<item>Pink Line</item>
<item>Yellow Line</item>
</string-array>
I need to convert Lines into ArrayList. If I use this
List<String> Lines = new ArrayList<String>();
to declare the ArrayList, how can find the array list by ID, and store that as Lines?
Solution 1:
Try this;
List<String> Lines = Arrays.asList(getResources().getStringArray(R.array.Lines));
and this for kotlin:
val Lines = resources.getStringArray(R.array.Lines).toList()
Solution 2:
In strings.xml, add string array
<string-array name="dashboard_tags">
<item>Home</item>
<item>Settings</item>
</string-array>
In your .java class access the string array like
List<String> tags = Arrays.asList(getResources().getStringArray(R.array.dashboard_tags));
Solution 3:
If anybody wondering how to do the same in kotlin
val universities = arrayListOf<String>(*resources.getStringArray(R.array.universities))
universities
will be ArrayList<String>
