Android 如何从数组更改为一个数组列表

我有这个数组，我把它作为一个参数发送给另一个活动， 如何使用一个数组列表添加此项？？？ 我试图使用数组列表类型模块，但我不能添加所有我不想添加的项目

    title = new String[]{"ahmad", "ali", "omar"};
    desc = new String[]{"China", "India", "United States"};
    background = new int[]{R.drawable.apple_ex,R.mipmap.ic_launcher,R.drawable.apple_ex};
    profile = new int[]{R.drawable.apple_ex,R.mipmap.ic_launcher,R.drawable.apple_ex};

创建一个模型类，如下所示：-

public class Model {

    private String title;
    private String desc;
    private int background;
    private int profile;

    public Model(String title, String desc, int background, int profile) {
        this.title = title;
        this.desc = desc;
        this.background = background;
        this.profile = profile;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }

    public int getBackground() {
        return background;
    }

    public void setBackground(int background) {
        this.background = background;
    }

    public int getProfile() {
        return profile;
    }

    public void setProfile(int profile) {
        this.profile = profile;
    }
}

ArrayList<Model> modelList = new ArrayList<>();

Model model1 = new Model("ahmad", "China", R.drawable.apple_ex, R.drawable.apple_ex);
Model model2 = new Model("ali", "India", R.mipmap.ic_launcher, R.drawable.apple_ex);
Model model3 = new Model("omar", "United States", R.mipmap.ic_launcher, R.drawable.apple_ex);

modelList.add(model1);
modelList.add(model2);
modelList.add(model3);

然后，当您必须在Arraylist中添加项时，只需创建一个包含适当项的模型，并按如下方式添加：-

public class Model {

    private String title;
    private String desc;
    private int background;
    private int profile;

    public Model(String title, String desc, int background, int profile) {
        this.title = title;
        this.desc = desc;
        this.background = background;
        this.profile = profile;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }

    public int getBackground() {
        return background;
    }

    public void setBackground(int background) {
        this.background = background;
    }

    public int getProfile() {
        return profile;
    }

    public void setProfile(int profile) {
        this.profile = profile;
    }
}

ArrayList<Model> modelList = new ArrayList<>();

Model model1 = new Model("ahmad", "China", R.drawable.apple_ex, R.drawable.apple_ex);
Model model2 = new Model("ali", "India", R.mipmap.ic_launcher, R.drawable.apple_ex);
Model model3 = new Model("omar", "United States", R.mipmap.ic_launcher, R.drawable.apple_ex);

modelList.add(model1);
modelList.add(model2);
modelList.add(model3);

你可以上课

public class Container{

  public String[]  title;
  public String[] desc;
  public int[] background ;
  public  int[] profile;

}

设置属性并通过序列化为字符串将其传递给其他活动。

是否希望标题、描述、背景、配置文件合并到一个列表中？是！将数据存储在列表中并在其他活动中使用为什么不使用Hashmap并放置这些数据。如果在Arraylist中循环，则不会得到类强制转换异常。通过使用Title、Desc作为键并将这些数组放入值中，可以将它们放置为HashMap。
