这个是使用ViewHolder常见的问题

 @Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        info = list.get(i);
        ViewHolder viewHolder;
        if(view==null) {
            viewHolder = new ViewHolder();
            view = LayoutInflater.from(getContext()).inflate(itemId, null);
            viewHolder.imageView = view.findViewById(R.id.app_icon);
            viewHolder.textView =  view.findViewById(R.id.app_packagename);
            viewHolder.checkBox =  view.findViewById(R.id.app_chechbox);
            view.setTag(viewHolder);
        }else{
            viewHolder = (ViewHolder) view.getTag();
        }
        if(checkingArray[i]==true){
            viewHolder.checkBox.setChecked(true);
            Log.d("click"+i+"", " set checkbox true");
        }else{
            viewHolder.checkBox.setChecked(false);
        }

        viewHolder.imageView.setImageDrawable(info.icon);
        viewHolder.textView.setText(info.packageName);
        final int a =i;
        viewHolder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                Log.d("check"+a, "onCheckedChanged: ");
                if (b) {
                    App.bannedApplicationList.add(info.packageName);
                   // info.ifChecked  = true;
                    checkingArray[a] = true;
                    Log.d("click"+a, "set true");
                }else{
                   // info.ifChecked = false;
                   // Log.d("listLength",App.bannedApplicationList.size()+"");
                }
            }
        });
        int length = checkingArray.length;
        for(int k=0;k<length;k++){
            if(checkingArray[k]==false){
                
            }
        }
        return view;
    }

只放出getView部分的代码
首先需要记一下点击checkbox时候的状态，这个状态的可以在List的实体类中添加一个布尔变量记录，那么判断这view的时候，如果true的话在set一下就可以。

但是经过观察：
在点击前面四个checkboxbox时，控制台输出
Log.d("check"+a, "onCheckedChanged: ");
没有问题，但是在向下滑动时候，会错误的认为其他的item也被点击。

这样，只需要换一个监听器就行（我还把item也设置为false）

@Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        info = list.get(i);
        ViewHolder viewHolder;
        if(view==null) {
            viewHolder = new ViewHolder();
            view = LayoutInflater.from(getContext()).inflate(itemId, null);
            viewHolder.imageView = view.findViewById(R.id.app_icon);
            viewHolder.textView =  view.findViewById(R.id.app_packagename);
            viewHolder.checkBox =  view.findViewById(R.id.app_chechbox);
            view.setTag(viewHolder);
        }else{
            viewHolder = (ViewHolder) view.getTag();
        }
        if(checkingArray[i]==true){
            viewHolder.checkBox.setChecked(true);
            Log.d("click"+i+"", " set checkbox true");
        }else{
            viewHolder.checkBox.setChecked(false);
        }

        viewHolder.imageView.setImageDrawable(info.icon);
        viewHolder.textView.setText(info.packageName);
        final int a =i;
        viewHolder.checkBox.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                checkingArray[a] = true;
                Log.d("click"+a, "onClick: ");
            }
        });
        return view;
    }
