java - 无法解析为变量

Question

我有这个代码

filethemeSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    public void onNothingSelected(AdapterView<?> parent) {
    }
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
        int throwid = (int)id;  
        System.out.println( "from onItemselected" +throwid);
    }
});

我尝试获取 throwid 变量的值，因此我创建了一个全局变量 themerowid 并且我这样做了:

themerowid = throwid;

但是我有这个错误:

throwid cannot be resolved to a variable

如何获取throwid值？

问题是 throwid 没有改变值，它总是返回 0 ，我认为漏洞代码:

filethemeSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    public void onNothingSelected(AdapterView<?> parent) {
    }
    public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
           throwid = (int)id;  
          System.out.println( "from onItemselected" +throwid);
    }
});

没有被执行，这就是为什么我一直得到 0，这段代码有错误。

看起来 thowid 不在可见范围内。试试这个:

    filethemeSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        public void onNothingSelected(AdapterView<?> parent) {
        }
        public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
              themerowid = (int)id;  
              System.out.println( "from onItemselected" + id);
        }
    });
