I have added a string-array of "distance" in my string.xml with a list of different distances and applied it within a Spinner in my second activity. I've also incorporated the Spinner in the second activities java folder. The problem I'm having is the distances are not populating in my spinner in the design. I don't know if the coding in Java is incorrect and is the reason it is not being displayed.

This is the strings.xml:

<string name="distancetravel">Distance willing to travel?</string>

<string-array name="distance">

    <item>Within 20 miles</item>

    <item>Within 50 miles</item>

    <item>Within 100 miles</item>

    <item>Endless Miles</item>

</string-array>

This is the activity2.xml:

<RelativeLayout

  <Spinner

    android:id="@+id/distancelist"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:entries="@array/distance"

    android:layout_below="@+id/distancetravel"

    android:layout_centerInParent="true" />

</RelativeLayout>

This is the Activity2.java:

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.widget.AdapterView;

import android.widget.ArrayAdapter;

import android.widget.Spinner;



public class Activity2 extends AppCompatActivity implements AdapterView.OnItemSelectedListener {



    Spinner spinner;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_activity2);



        spinner= (Spinner) findViewById(R.id.spinner);

        ArrayAdapter adapter=ArrayAdapter.createFromResource(this,R.array.distance,android.R.layout.simple_spinner_dropdown_item);

        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        spinner.setAdapter(adapter);

        spinner.setOnItemSelectedListener(this);

    }



    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.

        getMenuInflater().inflate(R.menu.menu_activity2, menu);

        return true;

    }



    @Override

    public boolean onOptionsItemSelected(MenuItem item) {

        // Handle action bar item clicks here. The action bar will

        // automatically handle clicks on the Home/Up button, so long

        // as you specify a parent activity in AndroidManifest.xml.

        int id = item.getItemId();



        //noinspection SimplifiableIfStatement

        if (id == R.id.action_settings) {

            return true;

        }



        return super.onOptionsItemSelected(item);

    }



    @Override

    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {



    }



    @Override

    public void onNothingSelected(AdapterView<?> parent) {



    }

}

Most of the time if R is not found then the issue is with the project itself and something is not resolving correctly. Try to clean and rebuild the project and see if R can be resolved. If that doesn't work, try passing it your array declared as a string array like so

String foo_array = mContext.getResources().getStringArray(R.array.foo_array);

Hope this helps !
