Android ListView不按筛选器刷新
在我的应用程序中，我有三个带有Android ListView不按筛选器刷新,android,android-listview,Android,Android Listview,在我的应用程序中，我有三个带有ViewPager的片段。其中一个片段是我从电话联系人列表中选择了简单的Arraylist作为ListView，在键入edittext后，我试图对其进行过滤。 但直到软键盘可见时才刷新，我必须隐藏键盘才能通过过滤字符串刷新列表视图 例如： editTextVideoFolderSearch = (EditText) rootView.findViewById(R.id.editTextVideoFolderSearch); editTextVideoFo
ViewPagerArraylistListViewedittext editTextVideoFolderSearch = (EditText) rootView.findViewById(R.id.editTextVideoFolderSearch);
editTextVideoFolderSearch.addTextChangedListener(new TextWatcher() {

int count) {
videoDetailBeansSearch.clear();
for (int i = 0; i < videoDetailBeans_total.size(); i++) {
if (videoDetailBeans_total.get(i).getAlbum().toLowerCase()
.contains(t)) {
videoDetailBeansSearch.add(videoDetailBeans_total.get(i));
}
}

当我关闭或隐藏使用nw项刷新的软键盘时，ListView成功地按筛选。从您发布的代码中可以看出，您没有使用适配器筛选器。我将在这里发布一个示例过滤器以及如何调用它（保留所有变量名以使其更简单） 适配器类中的“NameFilter”类：
public class NameFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();

- 如果“联系人列表”是联系人，请将其命名为“联系人”，以避免混淆
- 我会使用“搜索视图”，而不是“编辑文本”
- 我不知道你是如何得到联系人名单的，但是有一个指南（如果你还没有看的话）
