The final local variable cannot be assigned, since it is defined in an enclosing type

Android项目中遇到的问题，想弹出一个自定义dialog，dialog里有一个下拉列表spinner，当点击完item时，返回被选择的item。代码如下，
//添加事件Spinner事件监听 spinner.setOnItemSelectedListener(new OnItemSelectedListener() { public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) { keyFile=list.get(arg2); } public void onNothingSelected(AdapterView<?> arg0) { } }); 此时会报错The final local variable keyFile cannot be assigned, since it is defined in an enclosing type
解决办法：将本地变量改为局部或全局变量，即将本地变量keyFile定义在函数体外，即可解决。
感谢这里，英文好的话，原版解释在这。等有时间做详细翻译。
