Android Picasso没有加载我在drawable中列出的所有图像

Question

我有一个android picasso的问题。我的手机中没有加载某些图像。它只显示与手机不同的黑色页面。其他手机加载所有手机，而其他手机根本没有加载或有些手机丢失。

我正在使用适配器btw

这是我的适配器代码

        package com.jc.jcpremiere;



import com.squareup.picasso.Picasso;
import android.content.Context;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.RelativeLayout;

    public class ViewPagerAdapter extends PagerAdapter {
        // Declare Variables
        Context context;
        int[] flag;
        String[] rank;
        LayoutInflater inflater;

        public ViewPagerAdapter(Context context,  int[] flag, String[] rank) {
            this.context = context;
            this.flag = flag;
            this.rank = rank;
        }

        @Override
        public int getCount() {
            return rank.length;
        }

        @Override
        public boolean isViewFromObject(View view, Object object) {
            return view == ((RelativeLayout) object);
        }

        @Override
        public Object instantiateItem(ViewGroup container, int position) {
            inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View itemView = inflater.inflate(R.layout.app3x, container, false);
            ImageView imgflag = (ImageView) itemView.findViewById(R.id.items); // need this ImageView

            Picasso.with(context).load(flag[position]).resize(50, 50)
            .centerCrop().into(imgflag); // use ImageView
            //imgflag.setImageResource(flag[position]);
            ((ViewPager) container).addView(itemView);
            return itemView;
        }



        private ImageView findViewById(int items) {
            // TODO Auto-generated method stub
            return null;
        }

        @Override
        public void destroyItem(ViewGroup container, int position, Object object) {
            // Remove viewpager_item.xml from ViewPager
            ((ViewPager) container).removeView((RelativeLayout) object);

        }
    }
