Question

这是我的适配器的getView（） - 使用View Holder模式非常简单的实现：

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final Exercise exercise = mList.getItem(position);

        ViewExerciseHolder viewExerciseHolder;

            if(convertView == null) {

                viewExerciseHolder = new ViewExerciseHolder();
                LayoutInflater inflater = LayoutInflater.from(getContext());
                convertView = inflater.inflate(R.layout.item_view, parent, false);
                ...
                viewExerciseHolder.inputsLayout = (LinearLayout) convertView.findViewById(R.id.inputs);
                convertView.setTag(viewExerciseHolder);

            } else {
                viewExerciseHolder = (ViewExerciseHolder) convertView.getTag();
            }

            for (int i=0; i<exercise.nbSeries; i++) {

                ItemExerciseNbRepWeightView view = new ItemExerciseNbRepWeightView(getContext());

                view.setNbRep(exercise.nbReps);
                view.setWeight(exercise.weight);
                ...

                viewExerciseHolder.inputsLayout.addView(view);
            }
     }

问题是 inputsLayout ：添加的数据不正确，在滚动期间这些数据发生了变化......

感谢您的帮助！

Answer 1

嵌套的Layout被回收，这意味着它可能包含在之前调用getView()时添加的视图。您必须清除之前添加的所有View的回收'inputsLayout'。

执行此操作的一种方法是致电removeAllViews()。

Answer 2

试试这个，我已经通过在我的适配器类上解决了这个问题，

View view = null;

convertView = null;  in the get view and comments the else part of
    if (convertView == null) {
                }
                /*else{
                } */

Android：在滚动期间，ArrayAdapter中的ListView会发生变化
