android 在onClick中如何使用局部变量

Question

Variable groupPosition is accessed from within inner class,needs to be declared final.

Answer 1

 继承一下
 class MyClickListener implements View.OnClickListener {
        private int groupPosition;
        private int childPosition;
        public MyClickListener(int groupPosition,int childPosition){
            this.groupPosition = groupPosition;
            this.childPosition = childPosition;
        }
        public void onClick(View v) {
            System.out.println(this.groupPosition);
            System.out.println(this.childPosition);
        }
    }

        然后

        childImage.setOnClickListener(new MyClickListener(groupPosition,childPosition));
