为什么滚动后ListView项变得不可单击 [英] Why ListView Items becomes not clickable after scroll

问题描述

我用ImageView和TextViews创建了一个自定义的ListView，在我尝试实现onItemClick之前，每件事都运行良好，暂时只显示了Toast.

I created a custom ListView with ImageView and TextViews and every thing worked fine until i tried to implement onItemClick, which for the time being only shows a Toast.

当我向下滚动ListView时会出现问题:它将不会获得任何点击.

The problem occurs when i scroll down my ListView: it won't receive any clicks.

有趣的是，当我使用键盘从一个项目移动到另一个项目时，它会起作用，并且当我按下Enter键时，会显示Toast

Funny thing is that when i use the keyboard to move from item to item it works and when i hit enter the Toast is shown

这是我用于onItemClick侦听器的代码.

This is the code i used for onItemClick listener.

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    RestaurantReservationBean clickedItem = resultArray.get(position);

    Toast.makeText(this, clickedItem.getName()+", "+clickedItem.getCost(), 1000).show();
}

推荐答案

我认为我解决了这个问题:在阅读了一些文档之后，我发现这个问题来自每一行顶部的textviews和imagesviews，它们阻止了onitemselected听众.因此，我尝试在滚动后刷新列表视图，并且效果很好.这就是我希望它能帮助可能遇到此问题的人的地方

i think i solved this problem: after going through some documentation i figured out that this problem comes from the textviews and imagesview on top of each row which block the onitemselected listener. so i tryed to refresh the list view after scroll and it worked just fine. here's what i did hoping it 'll help those who may come accross this problem

listView.setOnScrollListener(new OnScrollListener() {
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            if ( scrollState == OnScrollListener.SCROLL_STATE_IDLE )
            {
              listView.invalidateViews();
            }

        }

        @Override
        public void onScroll(AbsListView arg0, int arg1, int arg2, int arg3) {}
    });
