错误集合

1.trying to draw too large(641336400bytes) bitmap.

将高分辨率图片放在了低分辨率文件夹下

 

例如：图片的分辨率是属于xxhdpi的，但错将这张图片放在了drawable-xhdpi或者比这个还低的文件夹下，解决的办法： 

a.人为的将这张图片的分辨率降低(一般不这样做) 

b.将高分辨率的图片放在drawable-xxhdpi或者drawable-xxxhdpi下即可

2.recyclerview点击事件中的页面跳转

这里的startActivity不能使用

解决方法：

@NonNull
@Override
public ShopsAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.information, viewGroup, false);
    final ViewHolder holder = new ViewHolder(view);
    holder .context=viewGroup.getContext() ;
    holder.tv_shopName.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            int position = holder.getAdapterPosition();
            Shops shops = list.get(position);
            Toast.makeText(view.getContext(), shops.getShopName(), Toast.LENGTH_SHORT).show();
        }
    });
    return holder;
}
以及

public ViewHolder(View view) {
    super(view);
    shopView =view;

    tv_shopName = (TextView) view.findViewById(R.id.tv_shopName);
    tv_userName = (TextView) view.findViewById(R.id.tv_userName);
    btn_open = (Button) view.findViewById(R.id.btn_open);
    btn_open.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String shopName = tv_shopName.getText().toString();
            Intent intent = new Intent();
            intent.setClass(shopView .getContext(),ShowGoods .class );
            intent.putExtra("shopName", shopName);
            shopView.getContext().startActivity(intent);
        }
    });
}
3.The application may be doing too much work on its main thread.
意思是：主线程中有耗时操作，主线程受不了了。
(还有这种操作？？？)
