java-Listview Onclick侦听器在更新Cardview布局后无法正常工作

概述当我将旧布局与ImageViews一起使用时,我已经更新了布局,将ImageViews替换为Buttons,并且ListviewOnCLick侦听器现在无法正常工作.如果需要进一步格式化,请告诉我,我们将提供任何帮助.活动中的侦听器：lvItem.setOnItemClickListener(newAdapterView.OnItemClickListener(){

当我将旧布局与ImageVIEws一起使用时,我已经更新了布局,将ImageVIEws替换为buttons,并且ListvIEw OnClick侦听器现在无法正常工作.如果需要进一步格式化,请告诉我,我们将提供任何帮助.

活动中的侦听器：

lvItem.setonItemClickListener(new AdapterVIEw.OnItemClickListener() {    @OverrIDe    public voID onItemClick(AdapterVIEw<?> parent, VIEw vIEw, int position, long ID) {        Intent intent = new Intent(MainActivity.this, ItemDetailsActivity.class);        intent.putExtra("position", position);        startActivity(intent);    }});

解决方法:

存在视图冲突的问题,即视图可能已被其他人重叠.

androID：descendantFocusability =“ blocksDescendants”放在您的父级布局和列表项上,对于您要为其处理点击事件的所有视图,androID：focusable =“ false”也会在按钮中添加此内容,就像在这里…
