java.lang.ArrayIndexOutOfBoundsException：length = 10; index = 10错误

我有四个活动使用单个适配器来显示微调器。调用适配器时，其中2个活动正常，但其中2个崩溃。给 ArrayIndexOutOfBoundsException：length = 10; index = 10错误。

这是代码

此活动不会崩溃并完美显示微调器及其项目

public class ArcherTowerActivity extends AppCompatActivity {

 Spinner sp1;
    Spinner sp2;
    Spinner sp3;
    Spinner sp4;
    Spinner sp5;
    Spinner sp6;
    Spinner sp7;
    Spinner sp8;
    TextView tx;
    Button sbmt;
    String levels[]={"Level 1",
            "Level 2",
            "Level 3",
            "Level 4",
            "Level 5",
            "Level 6",
            "Level 7",
            "Level 8",
            "Level 9",
            "Level 10",
            "Level 11",
            "Level 12",
            "Level 13",
            "Level 14",};
    int[] images={
            R.drawable.archer_tower1,
            R.drawable.archer_tower2,
            R.drawable.archer_tower3,
            R.drawable.archer_tower4,
            R.drawable.archer_tower5,
            R.drawable.archer_tower6,
            R.drawable.archer_tower7,
            R.drawable.archer_tower8,
            R.drawable.archer_tower9,
            R.drawable.archer_tower10,
            R.drawable.archer_tower11,
            R.drawable.archer_tower12,
            R.drawable.archer_tower13,
            R.drawable.archer_tower14,
    };



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_archer_tower);

        sbmt=(Button)findViewById(R.id.submit);
        tx=(TextView)findViewById(R.id.upgradeResult);
        sp1=(Spinner)findViewById(R.id.spinner);
        sp2=(Spinner)findViewById(R.id.spinner1);
        sp3=(Spinner)findViewById(R.id.spinner2);
        sp4=(Spinner)findViewById(R.id.spinner3);
        sp5=(Spinner)findViewById(R.id.spinner4);
        sp6=(Spinner)findViewById(R.id.spinner5);
        sp7=(Spinner)findViewById(R.id.spinner6);
        sp8=(Spinner)findViewById(R.id.spinner7);
        SpinnerAdapter adapter=new SpinnerAdapter(this,levels,images);
        sp1.setAdapter(adapter);
        sp2.setAdapter(adapter);
        sp3.setAdapter(adapter);
        sp4.setAdapter(adapter);
        sp5.setAdapter(adapter);
        sp6.setAdapter(adapter);
        sp7.setAdapter(adapter);
        sp8.setAdapter(adapter);

此活动无法执行此操作

public class MortarActivity extends AppCompatActivity {

    Spinner sp1;
    Spinner sp2;
    Spinner sp3;
    Spinner sp4;

    TextView tx;
    Button sbmt;
    String levels[]={"Level 1",
            "Level 2",
            "Level 3",
            "Level 4",
            "Level 5",
            "Level 6",
            "Level 7",
            "Level 8",
            "Level 9",
            "Level 10",
           };
    int[] images={
            R.drawable.mortar1,
            R.drawable.mortar2,
            R.drawable.mortar3,
            R.drawable.mortar4,
            R.drawable.mortar5,
            R.drawable.mortar6,
            R.drawable.mortar7,
            R.drawable.mortar8,
            R.drawable.mortar9,
            R.drawable.mortar10,

    };



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_mortar);

        sbmt=(Button)findViewById(R.id.submit);
        tx=(TextView)findViewById(R.id.upgradeResult); 
        sp1=(Spinner)findViewById(R.id.spinner);
        sp2=(Spinner)findViewById(R.id.spinner1);
        sp3=(Spinner)findViewById(R.id.spinner2);
        sp4=(Spinner)findViewById(R.id.spinner3);

        SpinnerAdapter adapter=new SpinnerAdapter(this,levels,images);
        sp1.setAdapter(adapter);
        sp2.setAdapter(adapter);
        sp3.setAdapter(adapter);
        sp4.setAdapter(adapter);

这是适配器代码

public class SpinnerAdapter extends ArrayAdapter <String>{


Context c;

    String[] levels;
    int[] images;

    public SpinnerAdapter(Context ctx,String[] levels, int[] images){

        super(ctx,R.layout.spinner_building_to_upgrade,levels);
        this.c=ctx;
        this.images=images;
        this.levels=levels;


    }


    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {


        if(convertView==null){

            LayoutInflater inflater=(LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView=inflater.inflate(R.layout.spinner_building_to_upgrade,null);
        }

        TextView tx=(TextView) convertView.findViewById(R.id.levelNumber);
        ImageView image=(ImageView)convertView.findViewById(R.id.imageid);

        //SET DATA
        tx.setText(levels[position]);
        image.setImageResource(images[position]);




        return convertView;
    }

    @NonNull
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if(convertView==null){

            LayoutInflater inflater=(LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView=inflater.inflate(R.layout.spinner_building_to_upgrade,null);
        }

        TextView tx=(TextView) convertView.findViewById(R.id.levelNumber);
        ImageView image=(ImageView)convertView.findViewById(R.id.imageid);

        //SET DATA
        tx.setText(levels[position]);
        image.setImageResource(images[position]);



        return convertView;
    }
}

First Activity有14个项目，Second Activity有10个项目。第二个崩溃给出了java.lang.ArrayIndexOutOfBoundsException：length = 10; index = 10错误。

编辑：

我已经找到了问题，如果我在阵列适配器中输入小于10的项目，它会崩溃并给出错误。为什么会这样？因为我没有设置任何最大最小长度。我想在微调器适配器中发送8个项目。请帮忙
