ArrayIndexOutOfBoundsException将项目保存在自定义适配器中

-1

使用12-14项目加载时，相同的适配器可以正常工作，但在加载少于10项时会出错。ArrayIndexOutOfBoundsException将项目保存在自定义适配器中

它导致当我输入6 items = ArrayIndexOutOfBoundsException：length = 6; index = 6

public class SpinnerAdapterAirSweeper extends ArrayAdapter <String>{ 


    Context c; 

    String[] levels; 
    int[] images; 

    public SpinnerAdapterAirSweeper(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 
     // if (levels.length > position) { 
      tx.setText(levels[position]); 
    // } 
    // if (images.length > position) { 
      image.setImageResource(images[position]); 
    // } 
//  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 

     // if (levels.length > position) { 
      tx.setText(levels[position]); 
    // } 
    // if (images.length > position) { 
      image.setImageResource(images[position]); 
    // } 
//  tx.setText(levels[position]); 
//  image.setImageResource(images[position]); 



     return convertView; 
    } 

    @Override 
    public int getItemViewType(int position) { 



     return super.getItemViewType(position); 
    } 
}

请给我提供一个解决方案和一个代码来解决这个问题。此适配器早期工作正常。由于

编辑：我这是如何将值传递给适配器

添加代码，您是如何将值传递给适配器 –

检查我的编辑@santoshkumar –

代码看起来不错干净生成N检查。 –

这是不是值试试这个。您已经添加额外这里逗号

String levels[]={"Level 1", 
      "Level 2", 
      "Level 3", 
      "Level 4", 
      "Level 5", 
      "Level 6" 

      }; 
    int[] images={ 
      R.drawable.air_sweeper1, 
      R.drawable.air_sweeper2, 
      R.drawable.air_sweeper3, 
      R.drawable.air_sweeper4, 
      R.drawable.air_sweeper5, 
      R.drawable.air_sweeper6 

    };
