how to read value from string.xml in android?

Question

I have written the line:

String Mess = R.string.mess_1 ;

to get string value, but instead of returning string, it is giving me id of type integer. How can I get its string value? I mentioned the string value in the string.xml file.

Answer 1

Try this

String mess = getResources().getString(R.string.mess_1);

UPDATE

String string = getString(R.string.hello);

You can use either getString(int) or getText(int) to retrieve a string. getText(int) will retain any rich text styling applied to the string.

Reference: https://developer.android.com/guide/topics/resources/string-resource.html

Answer 2

In Activity:

this.getString(R.string.resource_name)

If not in activity but have access to context:

context.getString(R.string.resource_name)
application.getString(R.string.resource_name)

Answer 3

I'm using this:

String URL = Resources.getSystem().getString(R.string.mess_1);

Answer 4

By the way, it is also possible to create string arrays in the strings.xml like so:

<string-array name="tabs_names"> 
    <item>My Tab 1</item> 
    <item>My Tab 2</item>
</string-array>

And then from your Activity you can get the reference like so:

String[] tab_names = getResources().getStringArray(R.array.tab_names);
String tabname1=tab_names[0];//"My Tab 1"

Answer 5

Only for future references.

In the String resources documentation it says:

You can use either getString(int) or getText(int) to retrieve a string. getText(int) will >retain any rich text styling applied to the string.

Answer 6

Solution 1

Context context;
String mess = context.getString(R.string.mess_1)

Solution 2

String mess = getString(R.string.mess_1)

Answer 7

In fragments, you can use

getActivity().getString(R.id.whatever);

Answer 8

If you want to add the string value to a button for example, simple use

android:text="@string/NameOfTheString"

The defined text in strings.xml looks like this:

 <string name="NameOfTheString">Test string</string>

Answer 9

You must reference Context name before using getResources() in Android.

String user=getApplicationContext().getResources().getString(R.string.muser);

OR

Context mcontext=getApplicationContext();

String user=mcontext.getResources().getString(R.string.muser);

• Kotlin version: 1.2.60

Task

• single line use
• minimum code
• use suggestions from the compiler

Step 1. Application()

Get link to the context of you application

class MY_APPLICATION_NAME: Application() {

    companion object {
        private lateinit var instance: MY_APPLICATION_NAME

        fun getAppContext(): Context = instance.applicationContext
    }

    override fun onCreate() {
        instance = this
        super.onCreate()
    }

}

Step 2. Add int extension

inline fun Int.toLocalizedString(): String = MY_APPLICATION_NAME.getAppContext().resources.getString(this)

Usage

strings.xml

<resources>
    <!-- .......  -->
    <string name="no_internet_connection">No internet connection</string>
    <!-- .......  -->
</resources>

Results

Answer 11

You can use this code:

 getText(R.string.mess_1); 

Basically, you need to pass the resource id as a parameter to the getText() method.

Answer 12

If you are in an activity you can use

getResources().getString(R.string.whatever_string_youWant);

If you are not in an Activity use this :

getApplicationContext.getResource().getString(R.String.Whatever_String_you_want)

Answer 13

while u write R. you are referring to the R.java class created by eclipse, use getResources().getString() and pass the id of the resource from which you are trying to read inside the getString() method.

Example : String[] yourStringArray = getResources().getStringArray(R.array.Your_array);

Answer 14

You can read directly the value defined into strings.xml:

<resources>
    <string name="hello">Hello StackOverflow!</string>
</resources>

and set into a variable:

String mymessage = getString(R.string.hello);

but we can define the string into the view:

<TextView
    android:id="@+id/myTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/hello"/>
