Android将值传递给类

我希望将此方法获得的数据（位于片段中）传递给扩展视图的类（此类位于与我的项目关联的库项目中）

片段中的方法

 public void checkOperatori(){
    SQLiteDatabase db = new DatabaseHelper(getActivity()).getReadableDatabase();
    String OPERATORI = "SELECT DISTINCT(nome), cognome FROM Operatori";
    Cursor cur = db.rawQuery(OPERATORI, null);
    int count = cur.getCount();
    String[] nome_op = new String[count];
    String[] cognome_op = new String[count];
    for(int i=0; i<count; i++) {
        cur.moveToNext();
        nome_op[i] = cur.getString(0);
        cognome_op[i] = cur.getString(1);
        mWeekView.setData(nome_op[i], cognome_op[i]);
    }


     cur.close();
     db.close();

}

为什么不在WeekView类中创建getter/setter方法呢

public class WeekView extends View {
    ...
    private String nome_op, cognome_op;
    public void setData(String nome_op, String cognome_op)
    {
        this.nome_op = nome_op;
        this.cognome_op = cognome_op
    }
    public String get_nome_op()
    {
        return nome_op;
    }
    public String get_cognome_op()
    {
        return cognome_op;
    }
}

然后：

编辑：

可能您正在使用类名而不是此类的对象调用函数。。比如：

WeekView.setData(nome_op, cognome_op);

您需要实例化一个变量

WeekView weekView = new WeekView();
weekView.set(nome_op, cognome_op);

如果要在不创建此类对象的情况下调用方法，则需要将该方法设置为static

顺便说一句，为什么您直接访问数据库？如果你想的话，你应该使用APImakestatic。我编辑了我的文章，因为我想传递2个数组。你能帮助我吗？谢谢你

this.nome_op=nome_op；this.cognome_op=cognome_op不兼容types@JJkk更改您的
私有字符串nome\u op，cognome\u op
to
private String[]nome\u op，cognome\u op
mWeekView.setData（nome_op，cognome_op）。至少投票并接受我的答案。我编辑了我的帖子，因为我想通过2个数组。你能帮助我吗？非常感谢。
public void setData(String[] nome_op, String[] cognome_op)
{
    this.nome_op = nome_op;
    this.cognome_op = cognome_op;
}
public String[] get_nome_op()
{
    return nome_op;
}
public String[] get_cognome_op()
{
    return cognome_op;
}

WeekView.setData(nome_op, cognome_op);

WeekView weekView = new WeekView();
weekView.set(nome_op, cognome_op);

public static String getSomething();
