Styling a SearchView in Android Action Bar

由 混江龙づ霸主 提交于 2019-11-26 15:53:09
问题 I have a search widget in my Action Bar like this: (1) How do I change the color of the text that says "iPhone"? (2) Also, if you notice the gray X -- the entire Search Widget is that color as well when it is in an icon position. I am on Holo.Theme.Light and utilizing my own mods to it. How do I change these two styles for the widget in my styles.xml file (assuming that is where you make the changes for a search widget)? 回答1: You would have to set searchView.setBackgroundColor(Color.WHITE);

问题 I'm trying to add a Search-ActionView to my application (as explained here http://developer.android.com/guide/topics/search/search-dialog.html#UsingSearchWidget).

Android - NullPointerException on SearchView in Action Bar

由 岁酱吖の 提交于 2019-11-26 13:04:15
I've got a problem trying to add a SearchView widget to the ActionBar in my activity - I get a null value when calling getActionView to get my SearchView object. I've been following the Android Developer guide and also went through a ton of SO questions as well as some other links on the Internet; all to no avail. It could be something simple but I wasn't able to figure it out - it seems to me my code is basically the same as that from google (apart from changing some names etc.) but it still won't work. Any help would be appreciated. Included below are relevant bits of the code. Please let me

问题 I found solutions for filters on ListView and SearchView on RecyclerView separately, but I wish to combine them. Is it even possible? 回答1: Yes it is possible Your RecyclerView.Adapter can implement Filterable . After that you have to override Filter getFilter() method. You have to define your own filter as is shown in the code below: @Override public Filter getFilter() { return new YourFilterClass(); } YourFilterClass class YourFilterClass extends Filter { @Override protected FilterResults
