Question

我将两个int从一个活动传递到另一个活动，作为我自己班级变量的一部分。

问题是这些值应该是0,0但它显示了一些随机数，如126435,4。

我班级（项目）的结构：

public class item implements Parcelable {
private int id;
private String title;
private String desc;
private double lat;
private double lon;
private String pub;
private int p;
private int n;
//private int cat;

public item(int id, String title, String desc, double lat, double lon, String pub, int p, int n) {
    super();
    this.id = id;
    this.title = title;
    this.desc = desc;
    this.lat = lat;
    this.lon = lon;
    this.pub = pub;
    this.p = p;
    this.n = n;
    //this.cat=cat;
}

添加额外变量（项目）:(我是正确的。我已经检查了它，它返回0,0原样：

Intent.putExtra("thing",markers.get(i));
startActivity(Intent);

但是当它通过并且我使用SetText将其设置为textView时，它会显示一些随机数字，我不知道它们来自哪里：

positive.setText(item.getP()+"");
negative.setText(item.getN()+"");

然后我从意图Extra获取项目：

item = getIntent().getParcelableExtra("thing");

谢谢你们！

我在Parcelable实现中没有以相同的顺序读写。
