android - SearchView 不搜索

Question

我正在尝试在我的应用程序布局中使用 SearchView 在我的 Android 应用程序中实现搜索功能。我有意选择将其放在布局中而不是操作栏中。

问题是，一旦我键入搜索文本并按下键盘上的回车/搜索键，就没有任何反应。永远不会调用可搜索的 Intent 。我觉得我一定是遗漏了一些导致搜索无法触发的东西

如果我没有按照下面的正确格式包含代码，我深表歉意。如果有任何其他信息有帮助，请告诉我。提前致谢!

您缺少 SearchView#setOnQueryTextListener。您需要覆盖 OnQueryTextSubmit() 方法才能实际执行和处理您的搜索。

编辑:我假设您正在查询数据库并使用游标获取结果。

mSearchView.setOnQueryTextListener(new OnQueryTextListener()
    {
        @Override
        public void onQueryTextSubmit(String query) {
            Cursor c = getContentResolver.query(URI, null, "col_1 = ? OR col_2 = ?", new String[] { query, query }, null);
            //Do whatever you want with your Cursor here
        }
    }
);
