为什么 ListView 项目在滚动后变得不可点击

发布于 2024-11-29 22:43:33 字数 609 浏览 1 评论 0原文

我使用 ImageView 和 TextViews 创建了一个自定义 ListView，一切都工作正常，直到我尝试实现 onItemClick，这暂时只显示一个Toast。

当我向下滚动 ListView 时出现问题：它不会收到任何点击。

有趣的是，当我使用键盘从一个项目移动到另一个项目时，它可以工作，当我按 Enter 时，会显示 Toast

这是我用于 onItemClick 侦听器的代码。

@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();
}

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.

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

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

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();
}

我想我解决了这个问题：在浏览了一些文档之后，我发现这个问题来自于每行顶部的 textviews 和 imagesview ，它们阻止了 onitemselected 侦听器。所以我尝试在滚动后刷新列表视图，效果很好。这就是我所做的希望它能帮助那些可能遇到这个问题的人

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) {}
    });

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) {}
    });
