跑的时候。APP一 滑动 就自动崩掉。
开始的时候:一直以为是事件分发的问题,Debug 了 好久也没有找到Exception dispatching input event. 中的 java.lang.NullPointerException,在哪里! 找了一上午 也没有头绪。
之后检查,ListView 适配器中的GetView() 方法的时候,发现,convertView
没有给view 赋值,而且返回的是 view.
解决方案:
View view = convertView;
Code:
@Override public View getView(int position, View convertView, ViewGroup parent) { // TODO 需要处理新款详情的 ListView布局 Log.i("love", "---getCount() size="+this.getCount()); // View view = convertView; if(view == null) { view = inflater.inflate(R.layout.fragment_new_fashtion_list_item, parent, false); } if(view != null) { ViewHolder holder = (ViewHolder)view.getTag(); if(holder == null) { holder = new ViewHolder(); holder.newImageView = (ImageView) view.findViewById(R.id.new_fashtion_item_image); holder.newTitleView = (TextView) view.findViewById(R.id.new_fashtion_item_title); holder.newShareBtn = (RadioButton) view.findViewById(R.id.new_fashtion_share_btn); holder.newCollectionBtn = (RadioButton) view.findViewById(R.id.new_fashtion_collection_btn); holder.newPriceBtn = (RadioButton) view.findViewById(R.id.new_fashtion_price_btn); view.setTag(holder); } // 获取当前的数据实体。 NewStyleItemEntity entity = (NewStyleItemEntity)newStyleLists.get(position); Log.i("love", "---position="+position); Log.i("love", "---entity= "+newStyleLists.get(position).getPrice()); holder.newTitleView.setText(newStyleLists.get(position).getTitle()); holder.newPriceBtn.append(newStyleLists.get(position).getPrice()); //图片的下载: } return view; }
