如何在Android的GridView中处理多个侦听器 [英] How to handle multiple listeners inside GridView in Android

问题描述

在我的应用中，GridView具有内容列表.每个项目都以布局夸大. gridview内部的单个项目包含一个图像和2个textviews.

In my app, a GridView has list of contents. Each item is inflated with a layout. Single item inside the gridview contains, an image and 2 textviews.

我有一个要求，当我单击该图像时，该图像应替换为另一图像，而当我单击任何其他位置时，则应打开一个弹出窗口.我可以使用OnItemClickListener收听第二个事件.打开弹出窗口.我该如何处理第一种情况?我的意思是我该如何收听OnClick图片事件?

I have a requirement that when I click on the image, the image should be replaced with another image and when I click on any other places it should open a popup. I am able to listen to the second event, using OnItemClickListener. It opens the popup. How can I handle the first case? I mean how can I listen to OnClick event of image?

推荐答案

在视图适配器中，设置图像资源时，还要为ImageView设置onClickListener.

In your view adapter, when you set the image resource, also set an onClickListener for the ImageView.

在我的情况下，holder是一个临时的静态类，其中包含2个TextViews和一个ImageView.:

In my case, holder is a temporary static class which holds 2 TextViews and an ImageView.:

holder.mThumbnailImageView = (ImageView) convertView.findViewById(R.list.thumb);
holder.mThumbnailImageView.setImageResource(thisOrder.getIconValue());
holder.mThumbnailImageView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Toast.makeText(parent.getContext(), "image clicked: " + view.getId(), Toast.LENGTH_SHORT).show();
    }
});
