cardView 选择上的持久角
persistent corners on cardView selection
我在列表项的背景上设置了一个角部带有半径的 cardView。
问题是当我单击 items/card 选择时,它包含角。起初我尝试使用 drawable/shape 然后使用 9 补丁图像,我得到了相同的结果。
我注意到当我在卡片上添加 clickable true 时,一切看起来都很好,但 intent 不再启动。

@Haider Saleem 和@Sam Raju 谢谢你们的帮助。我在自定义适配器中为卡设置了onclick,问题就解决了。
这是我所做的:
CardView cardView= listItemView.findViewById(R.id.card);
cardView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view)
{
// Find the current news that was clicked on
News currentNews = getItem(position);
// Convert the String URL into a URI object (to pass into the Intent constructor)
assert currentNews != null;
Uri newsUri = Uri.parse(currentNews.getUrl());
// Create a new intent to view the news URI
Intent websiteIntent = new Intent(Intent.ACTION_VIEW, newsUri);
// Send the intent to launch a new activity
getContext().startActivity(websiteIntent);
}
