package com.example.magazijnapp;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.MenuPopupWindow;
import android.os.Bundle;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.Spinner;
import android.widget.SpinnerAdapter;
import java.lang.reflect.Array;
public class MainActivity extends AppCompatActivity {
Spinner spinnermagazijn;
Button knop;
String[] magazijnarray;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
spinnermagazijn = findViewById(R.id.spinnermagazijn);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.
}
}
At the end of the line u see my problem.

You can do something like this:
Create the array with the hardcoded values in Strings.xml
<string-array name="my_array">
<item>Option 1</item>
<item>Option 2</item>
<item>Option 3</item>
<item>Option 4</item>
</string-array>
Now you add it as a property in your spinner, at MainActivity.xml
<Spinner
android:id="#+id/spinnermagazijn"
style="#style/Widget.AppCompat.Spinner.Underlined"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="2"
android:spinnerMode="dropdown"
android:padding="8dp"
android:entries="#array/my_array"
android:textSize="15sp"/>
If I get you right, this is what you are looking for.
