How do you access the values in the res/values/string.xml resource file from the Android Activity class?

Well you can get String using,

getString(R.string.app_name);

And, you can get string-array using

String arr[] = getResources().getStringArray(R.array.planet);
for (int i = 0; i < arr.length; i++) {
        Toast.makeText(getBaseContext(),arr[i], Toast.LENGTH_LONG).show();  
}

String resources, To access a String resource/value that you've defined in an XML file from your Android/Java code, use the Android getString method, like this: To access a String resource/value that you’ve defined in an XML file from your Android/Java code, use the Android getString method, like this: String prefsKeyTimeBetweenNotifications = getString(R.string.prefsKeyTimeBetweenNotifications);

Activity:

getString(R.string.some_text);

Android, android app and I wanted to use the string.xml resource instead of hardcoding the facts and hexadecimals.

Android values folder is used to set the values for the resources which are used in many Android projects. In the values folder, there are many types of files available like Colors, Styles, Strings, etc. The main purpose of using res/values folder remove the duplication of uses.

</string-array>

I am simply trying to get strings from regular Java (domain) classes within an Android app, but I am not able to get them by using getResources(). Is this possible? (I´d like to avoid creating a new strings.xml alike file in order to centralize all the strings within the app) Thanks in advance.

If getString(R.string.app_name); isn't working for you, you can pass context like this:

context.getString(R.string.app_name);

Understanding App Resources · codepath/android_guides Wiki , example: XML file saved at res/values/strings.xml : Resource pointer to an array of String s. resource reference: In Java: R.array.string_array_name; syntax: Accessing string values in Kotlin works exactly the same as it does in Java, just with Kotlin syntax: val string: String = getString(R.string.your_string_id) (This assumes that your code is inside an Android Activity, or a similar class that inherits from Context.

If you have the context of Activity, go with:

getString(R.string.app_name);

If you don't have the context, try below, you can get the context from activity using Constructor.

mContext.getString(R.string.app_name);

String Resources, Android best practices suggest that functionality and the resources supporting that a systematic way to access resources from XML files and from Java code. we will usually place string variable definitions in a file res/values/strings.xml, this  A class does not have a context and to use a string resource a context is needed. So just call the class from an activity and give a parameter context and within your class constructor just use that context to get the string resource. In your custom class you need to import the R namespace for the project to get the resource Id.

Managing Android Resources, Accessing Resources in Code android:name attribute value in the XML element (for a string from the Resources object, because Caution: You should never modify the R.java file  Also note that the whole language dependency can be taken care of by the android framework. Simply create different folders for each language. If english is your default language, just put the english strings into res/values/strings.xml. Then create a new folder values-ru and put the russian strings with identical names into res/values-ru

Accessing Resources, example: XML file saved at res/values/strings.xml : Resource pointer to an array of String s. resource reference: In Java: R.array.string_array_name; syntax: I have a Java project with a toolbar, and the toolbar has icons on it. These icons are stored in a folder called resources/, so for example the path might be "resources/icon1.png". This folder is located in my src directory, so when it is compiled the folder is copied into bin/ I'm using the following code to access the resources.

android.content.res.Resources.getString java code examples, Best Java code snippets using android.content.res.Resources.getString Android XML Percent Symbol getString(R.string.tab_repositories); case 1: return resources. Most clients will use output streams that write data to the file system (. Note: A string is a simple resource that is referenced using the value provided in the name attribute (not the name of the XML file).

  • Note that getString() is not static. If you want to assign a string.xml value to a static property of your app class, do it in you class onCreate().
  • @MByD That's the first tim I was faster then you =)
  • <string-array name="planet"> <item>Mercury</item> <item>Venus</item> <item>Earth</item></string-array>
