这段代码存在一个错误，`bigImageLoader(bitmap)`方法应该在`onCreateView`方法内部调用，而不是在类声明处调用。修改后的代码如下：

package com.example.dzy;  

import android.app.Dialog; 
import android.graphics.Bitmap; 
import android.graphics.BitmapFactory; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ImageView; 
import android.widget.LinearLayout;  
import androidx.annotation.NonNull; 
import androidx.annotation.Nullable; 
import androidx.fragment.app.Fragment;  

import java.io.InputStream;  

public class Fragment_1 extends Fragment {     
    private ImageView imageView_1,imageView_2;     
    @Nullable     
    @Override     
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {         
        View view = inflater.inflate(R.layout.activity_shouye, container, false);         
        imageView_1=(ImageView)view.findViewById(R.id.image_show1);         
        imageView_1.setImageBitmap(bitmap);         
        imageView_1.setOnClickListener(new View.OnClickListener(){             
            @Override             
            public void onClick(View v){                 
                bigImageLoader(bitmap);             
            }         
        });         
        return view;     
    }      

    Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.mipmap.show1);      

    //方法里直接实例化一个imageView不用xml文件，传入bitmap设置图片     
    private void bigImageLoader(Bitmap bitmap){         
        final Dialog dialog = new Dialog(getActivity());         
        ImageView image = new ImageView(getContext());         
        image.setImageBitmap(bitmap);         
        dialog.setContentView(image);         
        //将dialog周围的白块设置为透明         
        dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);         
        //显示         
        dialog.show();         
        //点击图片取消         
        image.setOnClickListener(new View.OnClickListener(){             
            @Override             
            public void onClick(View v){                 
                dialog.cancel();             
            }         
        });     
    }      
}

这里将`bigImageLoader`方法改为在`imageView_1`的点击事件中调用，这样点击图片时才会调用显示大图的方法。同时，也将`bigImageLoader`方法移到了类的内部，以方便调用。
