Question

大家好我在Android开发中遇到了一个问题。我还在开发一个Android应用程序。所以我遇到了android listview的问题。

我的问题是，我想在一个列表视图中显示两个数据项。像这样：

 Recipt No :Date
 001       :2017/11/30

所以现在我使用Arrayadapter加载一个数据元素。但现在我想在列表视图中加载两个数据

下面我把我的java代码加载到列表视图中的一个数据。

 public void showList()
{
    String[] ides = new String[de1.size()];     

    for (int i = 0; i < de1.size(); i++) {

        ides[i] = de1.get(i).getId().toString();



    }
   ArrayAdapter adapter = new ArrayAdapter<String>(depositDetails.this,R.layout.depositlists,R.id.b,ides);


         listViewlist.setAdapter(adapter);



}

xml代码部分

    <LinearLayout
        android:layout_width="500dp"
        android:layout_height="67dp"
        android:layout_marginBottom="8dp"

    </LinearLayout>

Answer 1

使用自定义适配器

public class CustomAdapter extends ArrayAdapter<User> {

Context context;
ArrayList<User> userArrayList;
public CustomAdapter(Context context,ArrayList<User> userArrayList) {
    super(context, R.layout.depositlists, userArrayList);
    this.context=context;
    this.userArrayList=userArrayList;

}

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


    if (convertView == null) {
        convertView = LayoutInflater.from(getContext()).inflate(R.layout.depositlists, parent, false);
    }

    User user = getItem(position);


    TextView b = (TextView) convertView.findViewById(R.id.b);
    TextView Status = (TextView) convertView.findViewById(R.id.Status);

    b.setText(user.getReciptNo());
    Status.setText(user.getDate());

    return convertView;
}
}


Replace showList method  

public void showList()
{
    ArrayList<User> users = new ArrayList<>();

    for (int i = 0; i < de1.size(); i++) {

        users.add(new User(i,de1.get(i).getId().toString()));

    }
    CustomAdapter adapter = new CustomAdapter(depositDetails.this,users);

    listViewlist.setAdapter(adapter);
    }


Add User Class


public class User {
String  ReciptNo;
String Date;

public User(String reciptNo, String date) {
    ReciptNo = reciptNo;
    Date = date;
}

public String getReciptNo() {
    return ReciptNo;
}

public void setReciptNo(String reciptNo) {
    ReciptNo = reciptNo;
}

public String getDate() {
    return Date;
}

public void setDate(String date) {
    Date = date;
}
}
