java - 安卓 : How can I update a variable after using in for loop

Question

我已经完成了这段代码，

if (k == 21 && click1 == true)
{   
    for (k = 21; k < 39; k++) {
        Spinner sp = (Spinner) gridLayout.getChildAt(k);
        String value = (String) sp.getSelectedItem();
        Log.d("Spinner value als string", value);
        if (!value.isEmpty()) {
            value1 = Integer.parseInt(value);
            ("Spinner value als invert", ""+ value1);
            sum = sum + value1;
            Log.d("Totall Value", "" + sum);
        }
    }
}

此处，值 k 在迭代后已更新为 39，我想将此值用作变量 39，以便接下来此循环不会再次启动，我可以将其用于另一个循环或迭代。需要帮助 !!

如果我理解正确的话，剩下的就是将此变量声明为类字段。

public class YourClass {

    public int k = 0;

    public void yourMethod(){
        if (k == 21 && click1 == true)
        {   
            for (k = 21; k < 39; k++) {
                Spinner sp = (Spinner) gridLayout.getChildAt(k);
                String value = (String) sp.getSelectedItem();
                Log.d("Spinner value als string", value);
                if (!value.isEmpty()) {
                    value1 = Integer.parseInt(value);
                    ("Spinner value als invert", ""+ value1);
                    sum = sum + value1;
                    Log.d("Totall Value", "" + sum);
                }
             }
        }

    }
}
