当我检查CheckBox中的项目时，还会检查其他项目。
我的应用有ListView个联系人姓名和CheckBox。此外，用户可以多选列表中的名称。
我有3个班级
感谢您的帮助。

答案 0 :(得分：0)
您正在检查OnItemClickListener中的复选框。那不行。
在适配器中，您有每个项目在<form>中显示的字符串。您还需要一个布尔数组/列表来跟踪每个项目的复选框状态。
在适配器TextView中，您需要获取该位置的checked-state布尔值，然后找到复选框视图并根据布尔值设置复选框状态。
在getView()中，您需要更新该位置的布尔值，并在适配器上调用OnItemClickListener。
我建议您阅读notifyDataSetChanged()并真正了解回收视图时发生的情况，以便了解每个子视图的状态必须保存在适配器中的原因。
ListView然后在你的活动中：
public class SelectUserAdapter extends BaseAdapter{
private Context context;
private String[][] lis;
private boolean[] checkedState;
public SelectUserAdapter(Context c, String[][] li) {
context = c;
lis = li;
checkedState = new boolean[lis.length];
}
// ...
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.contact_row, parent, false);
}
TextView txtName = (TextView) convertView.findViewById(R.id.name);
txtName.setPadding(10, 0, 0, 0);
txtName.setText(lis[position][1].toString());
CheckBox cb = (CheckBox) convertView.findViewById(R.id.check);
cb.setChecked(checkedState[position]);
return convertView;
}
public void markSelected(int position) {
checkedState[position] = true;
notifyDataSetChanged(); // refresh the ListView
}
}
