您好我在listview中使用复选框，但是当我滚动列表视图时，复选框会自动取消选中或选中。
public class MyContactsAdapter extends BaseAdapter {
private LayoutInflater inflater;
private List<Friend> mAllFriends;
public MyContactsAdapter(Context context,List<Friend> allFriends) {
inflater = LayoutInflater.from(context);
this.mAllFriends =allFriends;
}
@Override
public int getCount() {
if(mAllFriends==null)
{
return 0;
}else{
return mAllFriends.size();
}
}
@Override
public Object getItem(int position) {
return mAllFriends.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder mHolder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.contact_list_item, null);
mHolder = new ViewHolder();
mHolder.mProFileImage = (ImageView) convertView
.findViewById(R.id.profleImage);
mHolder.mPersonName = (TextView) convertView
.findViewById(R.id.person_Name);
mHolder.mEmailId = (TextView) convertView
.findViewById(R.id.person_emailId);
mHolder.mSelectPerson = (CheckBox)convertView.findViewById(R.id.personSelect);
mHolder.mSelectAllLabel = (TextView)convertView.findViewById(R.id.personSelectAllLabel);
convertView.setTag(mHolder);
} else {
mHolder = (ViewHolder) convertView.getTag();
}
if(position==0)
{
mHolder.mProFileImage.setVisibility(View.GONE);
mHolder.mPersonName.setVisibility(View.GONE);
mHolder.mEmailId.setVisibility(View.GONE);
mHolder.mSelectAllLabel.setVisibility(View.VISIBLE);
}else{
mHolder.mProFileImage.setVisibility(View.VISIBLE);
mHolder.mPersonName.setVisibility(View.VISIBLE);
mHolder.mEmailId.setVisibility(View.VISIBLE);
mHolder.mSelectAllLabel.setVisibility(View.GONE);
}
mHolder.mProFileImage.setImageResource(R.drawable.ic_launcher);
mHolder.mPersonName.setText(""+mAllFriends.get(position).getName());
mHolder.mEmailId.setText(""+mAllFriends.get(position).getEmail());
mHolder.mSelectPerson.setTag(position);
mHolder.mSelectPerson.setChecked(mAllFriends.get(position).isSelected());
mHolder.mSelectPerson.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
mAllFriends.get((Integer) buttonView.getTag()).setSelected(isChecked);
}
});
return convertView;
}
private static class ViewHolder {
ImageView mProFileImage;
TextView mPersonName;
TextView mEmailId;
CheckBox mSelectPerson;
TextView mSelectAllLabel;
}
}
