Question

  private class ContactListAdapter extends ArrayAdapter<import_fragment.Contact> {
    public ContactListAdapter() {
        super (main_fragment.this, R.layout.fragment_import, Contacts);
    }

    @Override
    public View getView(int position, View view, ViewGroup parent) {
        if (view == null)
            view = getActivity().getLayoutInflater().inflate(R.layout.fragment_import, parent, false);

        import_fragment.Contact currentContact = Contacts.get(position);

        TextView name = (TextView) view.findViewById(R.id.contactName);
        name.setText(currentContact.getName());
        TextView phone = (TextView) view.findViewById(R.id.phoneNumber);
        phone.setText(currentContact.getPhone());
        TextView email = (TextView) view.findViewById(R.id.emailAddress);
        email.setText(currentContact.getEmail());
        TextView address = (TextView) view.findViewById(R.id.cAddress);
        address.setText(currentContact.getAddress());


        return view;
    }

当我尝试更改R.layout.import_fragment（我的其他片段）时，此行super (main_fragment.this, R.layout.fragment_import, Contacts); 有错误说*无法解析方法'super（com.al3almya.users.al3almya.main_fragment，int，java.util.List）;

当我输入其他片段布局时，我收到此错误。

Answer 1

ArrayAdapter的第一个参数是Context，但您传递com.al3almya.users.al3almya.main_fragment，这是错误的。

将您的方法签名更改为此

public ContactListAdapter(Context cntx) {
    super (cntx, R.layout.fragment_import, Contacts);
}

当你调用适配器时使用这个

new ContactListAdapter(this); // if called from activity

或

new ContactListAdapter(getActivity); // if called from fragment

调用另一个片段时ListAdapter错误
