来自WEB的源代码调用

Question

我对这部分非常新，并有一个问题。

我有一个带菜单的应用程序。文件名是NavItem.java并具有以下代码：

package de.digisocken.anotherrss;

import java.util.ArrayList;

/**

public class NavItem {

public static final int TYPE_HEADER = 1;
public static final int TYPE_ROW = 2;

public static final int TYPE_WEB = 1;
public static final int TYPE_RSS = 2;

private String label, url;
private int icon;
private int itemType = TYPE_HEADER;
private int linkType = TYPE_WEB;

public NavItem(int itemType, String label, int icon, String url, int linkType) {
    this.itemType = itemType;
    this.label = label;
    this.icon = icon;
    this.url = url;
    this.linkType = linkType;
}

public String getLabel() {
    return label;
}

public void setLabel(String label) {
    this.label = label;
}

public String getUrl() {
    return url;
}

public void setUrl(String url) {
    this.url = url;
}

public int getIcon() {
    return icon;
}

public void setIcon(int icon) {
    this.icon = icon;
}

public int getItemType() {
    return itemType;
}

public void setItemType(int itemType) {
    this.itemType = itemType;
}

public int getLinkType() {
    return linkType;
}

public void setLinkType(int linkType) {
    this.linkType = linkType;
}

public static ArrayList<NavItem> getDrawerItems() {
    ArrayList<NavItem> mListItem = new ArrayList<>();

    mListItem.add(new NavItem(TYPE_HEADER, "Category 1", 0, null, 0));
    mListItem.add(new NavItem(TYPE_ROW, "Wiki", R.drawable.ic_language, "https://de.wikipedia.org/wiki/Amstetten", TYPE_WEB));

    return mListItem;

}
}

是否有可能我在网上上传此文件并且应用程序通过链接调用它？如果是的话新代码是什么？
