我有一个问题很想得到答案。

我有两个数组，比方说：

String[] name = {"Name Nameson", "Second Name"};
String[] number = {"111 11 111", "222 22 222"};

我希望我的 ListView 将两个 TextView 合并到一个项目中。（我试图用图片来说明这一点）。

我设法得到 f.ex。用一个简单的方法将我的名字数组放入列表视图

lv.setAdapter(new ArrayAdapter<String>(this, R.layout.single_name, name));

我有我的 main.xml 和我的 ListView，我的布局文件夹中有 single_name.xml 和 single_number.xml。

由于我是该网站的新手，因此不允许添加图片，因此我将在此处尝试说明：

标题

（项目一）

名称 Nameson

111 11 111

（项目二）

第二个名字

222 22 222

这取决于联系人的数量。

任何帮助将不胜感激 ：）

提前致谢！

你必须建立自己的适配器。

您可以修改这个以供您使用，它使用查看器模式来提高性能。

public class WifiListAdapter extends BaseAdapter {

    private ArrayList<Wifi> entries;
    private Location location;
    private boolean withDistance;

    public static class ViewHolder{
        public TextView ssid;
        public TextView crypt;
        public TextView distance;

    }

    public WifiListAdapter(ArrayList<Wifi> entries, Location location) {
        this.entries = entries;
        this.location = location;
        withDistance = true;
    }

    public int getCount() {
        return entries.size();
    }

    public Wifi getItem(int position) {
        return entries.get(position);
    }


    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        View vi = convertView;
        ViewHolder holder;
        if(convertView == null){
            vi =  MyApplication.getLayoutInflater().inflate(R.layout.wifi_list_item, null);
            holder = new ViewHolder();
            holder.ssid = (TextView)vi.findViewById(R.id.wifi_list_ssid);
            holder.crypt = (TextView)vi.findViewById(R.id.wifi_list_crypt);
            holder.distance = (TextView)vi.findViewById(R.id.wifi_list_distance);

            vi.setTag(holder);


        }
        else{
            holder = (ViewHolder)vi.getTag();
        }
        Wifi wifi = entries.get(position);

        holder.ssid.setText(wifi.ssid);

        StringBuilder cryptString = new StringBuilder(20);

        if(wifi.wep == 1)
            cryptString.append("WEP ");
        if(wifi.wpa == 1)
            cryptString.append("WPA ");
        if(wifi.wpa2 == 1)
            cryptString.append("WPA2 ");
        if(wifi.wps == 1)
            cryptString.append("WPS ");
        if(wifi.ess == 1)
            cryptString.append("ESS");


        String distanceString;
        if(withDistance) {
            float[] results = new float[1];
            Location.distanceBetween(location.getLatitude(), location.getLongitude(), wifi.lat, wifi.lng, results);
            distanceString = MyApplication.formatDistance(results[0]);
        } else
            distanceString = "unknown";

        holder.distance.setText(distanceString);

        holder.crypt.setText(cryptString.toString().trim());
        //holder.distance.setText(results[0] + "");


        holder.ssid.setTag(position);
        holder.crypt.setTag(position);
        holder.distance.setTag(position);


        return vi;
    }

}

您将需要构建一个自定义适配器以及一个自定义视图来表示列表中的每一行。

这是一个简单适配器的示例，用于具有 2 个文本视图和一个图像视图的列表视图。根据您认为合适的方式进行修改以包含您的标题并取出图像视图

package com.aquarius.customlistviewproject;


public class CustomListViewAdapter extends BaseAdapter{


 private ArrayList<String> album_names;

private ArrayList<String> num_photos;

 public Activity context;

public LayoutInflater inflater;

 public CustomListViewAdapter(Activity context, ArrayList<String> album_names ,     ArrayList<String> num_photos){

super();
this.album_names = album_names;
this.num_photos = num_photos;
this.context = context;
this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}


public Object getItem(int position) {
    // TODO Auto-generated method stub
    return null;
}

public long getItemId(int position) {
    // TODO Auto-generated method stub
    return 0;
}

public int getCount() {
    // TODO Auto-generated method stub
    return album_names.size();
}

public class ViewHolder{

    ImageView thumbnail;
    TextView  title;
    TextView photos;
}

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

    ViewHolder holder;

    if(convertView == null){
        holder = new ViewHolder();
        convertView = inflater.inflate(R.layout.listview_row, null);

        holder.thumbnail = (ImageView)convertView.findViewById(R.id.imgViewLogo);
        holder.title = (TextView)convertView.findViewById(R.id.txtViewTitle);
        holder.photos = (TextView)convertView.findViewById(R.id.txtViewDescription);


        convertView.setTag(holder);
    }

    else
        holder = (ViewHolder)convertView.getTag();
        holder.thumbnail.setImageResource(R.drawable.imgview_drawable);

        holder.title.setText(album_names.get(position));
        holder.photos.setText(num_photos.get(position));
    return convertView;
}

}

您需要创建一个自定义适配器

ArrayAdapter<HashMap<String,String>>
