android – 如何在自定义列表视图中搜索

概述嗨我有一个自定义列表视图,但我无法编码正确的方式只过滤/搜索CustomListView中的特定人名(基本上我从 JSON得到这个并存储在ArrayList中)…请任何人帮我这个方法在CustomListViewAdapter.java中过滤 这是我的Main_Activity.Java代码 array111.add(new AshTable(test1, test2, test3, test4, 嗨我有一个自定义列表视图,但我无法编码正确的方式只过滤/搜索CustomListVIEw中的特定人名(基本上我从 JSON得到这个并存储在ArrayList中)…请任何人帮我这个方法在CustomListVIEwAdapter.java中过滤

这是我的Main_Activity.Java代码

请帮助我使用此方法过滤器仅过滤人名或日期….提前谢谢

解决方法 根据此示例代码更改adapeter类,并专注于getFilter方法,尽管我已粘贴完整的适配器类供您参考.

并在搜索视图中使用此方法：

@OverrIDe    public boolean onCreateOptionsMenu(Menu menu) {        MenuInflater inflater = getMenuInflater();        // Inflate menu to add items to action bar if it is present.        inflater.inflate(R.menu.main,menu);        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);        SearchVIEw search = (SearchVIEw) menu.findItem(R.ID.action_search).getActionVIEw();        search.setSearchableInfo(manager.getSearchableInfo(getComponentname()));        search.setonqueryTextListener(new SearchVIEw.OnqueryTextListener() {            @OverrIDe            public boolean onqueryTextsubmit(String query) {                return true;            }            @OverrIDe            public boolean onqueryTextChange(String newText) {                adapter.getFilter(getComponentname()).filter(newText);                adapter.notifyDataSetChanged();                return false;            }        });        return true;    }
