Question

我有一个模型，我想制作一个这样的数组。问题是我这样做：

我的代码：

final WifiModel itemsData[] = {
                new WifiModel(nearbyAccessPoints.get(0).SSID, "name"),
                new WifiModel(nearbyAccessPoints.get(1).SSID, "name"),
                new WifiModel(nearbyAccessPoints.get(2).SSID, "name"),
                new WifiModel(nearbyAccessPoints.get(3).SSID, "name"),
                new WifiModel(nearbyAccessPoints.get(4).SSID, "name"),
        };

我想做一个i ++表格，例如i = 4。我怎么能这样做？

我的模特：

public class WifiModel {

    private String SSID;
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    WifiModel(String SSID, String name) {
        this.SSID = SSID;
        this.name = name;
    }

    public String getSSID() {
        return SSID;
    }

    public void setSSID(String SSID) {
        this.SSID = SSID;
    }
}

Answer 1

简单：）

WifiModel itemsData[] = new WifiModel[5]; 
for(int i=0; i<5; i++) itemsData[i]=new WifiModel(nearbyAccessPoints.get(i).SSID, "name");

Answer 2

数组不是动态长度。您可以使用ArrayList来实现此目标，如下所示：

ArrayList<WifiModel> itemsData = new ArrayList<>();

int n=4; // any number you want
for(int i=0;i<n;i++)
{
itemData.add(new WifiModel(nearbyAccessPoints.get(i).SSID, "name"));
}

Answer 3

试试这个：

List<WifiModel> list = new ArrayList<>();
WifiModel wifi=null;
int i;
for(i=0; i<4; i++){
    wifi = new WifiModel(nearbyAccessPoints.get(i).SSID, "name");
    list.add(wifi);
}

使用自动增量创建我的模型数组
