我有一个带有复选框的列表视图

下面是我的getView方法

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        view = convertView;

        if (convertView == null) {
            //inflate the view for each row of listview
            view = layoutInflater.inflate(R.layout.rating_item, null);
            mViewHolder = new ViewHolder();

            mViewHolder.mstatus = (TextView) view.findViewById(R.id.ratingStatus);
            mViewHolder.mCheckBox = (CheckBox) view.findViewById(R.id.checkBox);
            view.setTag(mViewHolder);
        } else {
            mViewHolder = (ViewHolder) view.getTag();
        }

        if (StarListHolder.getInstance().getStarOne().toString() != null) {

            String starTest = String.valueOf(listForView.get(position));
            ArrayList<String> starOne = StarListHolder.getInstance().getStarOne();
            List<String> starList = StarTest.getInstance().getStarList();
            mViewHolder.mstatus.setText(starList.get(position));
        }
        return view;
    }}

我如何知道用户正在检查的复选框的数量。

//关于活动或片段类
//On your Activity or fragment Class
btn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {   



int count = listView.getAdapter().getCount();
            LinearLayout ll=(LinearLayout)v.findViewById(R.id.ll1);

            for (int i = 0; i < count; i++) {

                ll = (LinearLayout) gridView.getChildAt(i);

                CheckBox cb = (CheckBox)ll.findViewById(R.id.checkbox1);
                TextView tv = (TextView)ll.findViewById(R.id.textView1);
                //  StringBuilder stringBuilder=new StringBuilder();
                if (cb.isChecked()) {

                    Log.e("CheckBoxch", "" + cb.getTag().toString());
                    Log.e("text", "" + tv.getTag().toString());
                    stringBuilder.append(tv.getTag().toString() + ",");
                    type_of_truck_appended = stringBuilder.toString();
                    if (pwindowforTruckName.isShowing()) {
                        pwindowforTruckName.dismiss();
                    }

像这样试试。

private static int checkBoxCounter = 0;

mViewHolder.mCheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if(isChecked && checkBoxCounter>=2){
            list.get(position).setChecked(false);
            mViewHolder.mCheckBox.setChecked(false);

        }else {
            if (isChecked) {
                starOne.add((Integer) mViewHolder.mCheckBox.getTag());
                checkBoxCounter++;              
            } else {
                checkBoxCounter--;
            }
            cCheckedItems.setText(checkBoxCounter); //<-- ADD THIS
            Toast.makeText(context, "there are " + checkBoxCounter + " items selected", Toast.LENGTH_LONG).show();
        }}});

在适配器中全局定义它。

private static int checkBoxCounter = 0;

mViewHolder.mCheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if(isChecked && checkBoxCounter>=2){
            list.get(position).setChecked(false);
            mViewHolder.mCheckBox.setChecked(false);

        }else {
            if (isChecked) {
                starOne.add((Integer) mViewHolder.mCheckBox.getTag());
                checkBoxCounter++;              
            } else {
                checkBoxCounter--;
            }
            cCheckedItems.setText(checkBoxCounter); //<-- ADD THIS
            Toast.makeText(context, "there are " + checkBoxCounter + " items selected", Toast.LENGTH_LONG).show();
        }}});

我猜您会想对这些数据做些什么&反映列表中的更改。以下是步骤：
1） 在适配器中创建一个接口
2） 根据您分别使用的是RecyclerView
还是BaseAdapter
方法，在onBindViewHolder
方法或getView
方法内的整行/复选框上应用点击侦听器
3） 在活动中实现该接口并通知适配器已在Li中进行了更改
