adapter

The text on my spinners is white, and I have no idea why. This is my xml, nothing special <Spinner android:id="@+id/spinner_date" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" /> And my code dateSpinner = (Spinner) findViewById(R.id.spinner_date); selectedDate = calendar.getTime(); List<String> list = new ArrayList<String>(); list.add(formatter.format(selectedDate)); dateAdapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_spinner_item, list); dateSpinner.setAdapter(dateAdapter); What could be the reason that my text is displayed in

What are containers/adapters ? Someone please explain in layman's language . I have tried to look up on the internet but the definitions and explanations are too technical and hard to understand. I have basic knowledge of C++ and its sub-topics like (class/templates/STL). EDIT 1: Can anyone please give me a practical example of the application of containers/adapters? Just for better understanding :-) Thank you. <joke> C++ is technical and hard to understand :-D </joke> Containers are data types from STL that can contain data. Example: vector as a dynamic array Adapters are data types from STL

上期回顾 上一篇文章《 Tomcat在SpringBoot中是如何启动的 》从main方法启动说起，窥探了SpringBoot是如何启动Tomcat的，在分析Tomcat中我们重点提到了，Tomcat主要包括2个组件，连接器（Connector）和容器（Container）以及他们的内部结构图，那么今天我们来分析下Tomcat中的连接器是怎么设计的以及它的作用是什么。 说明：本文tomcat版本是9.0.21，不建议零基础读者阅读。 从连接器（Connector）源码说起 既然是来解析连接器（Connector），那么我们直接从源码入手，后面所有源码我会剔除不重要部分，所以会忽略大部分源码细节，只关注流程。源码如下（高能预警，大量代码）： public class Connector extends LifecycleMBeanBase { public Connector() { this("org.apache.coyote.http11.Http11NioProtocol"); } public Connector(String protocol) { boolean aprConnector = AprLifecycleListener.isAprAvailable() && AprLifecycleListener.getUseAprConnector(); if (

Is it possible for setting more than one adapter to a single list? For example list.setAdapter(adapter1); list.setAdapter(adapter2); Slartibartfast Maybe you can try attaching multiple adapters to a single adapter like here android attaching multiple adapters to one adapter Or maybe this http://jsharkey.org/blog/2008/08/18/separating-lists-with-headers-in-android-09/ if I understand what you need it for correctly Pls update why you want it for so we have a better understanding 来源： https://stackoverflow.com/questions/11118809/setting-more-than-one-adapter-for-a-single-list-view

I have been googling and searching to resolve this error for some time and I can`t seem to find out why and how to solve it. I`m using a customAdapter to fill in my listview. I inflate the xml describing my listItem. I make viewHolder object and load in my textview using findViewById. After that i want to set the text of that textview but it findViewbyid returns a null value. So automaticcally resolving into a nullpointerexception. Adapter: /** CLASS : Custom Adapter for the listview */ private class CustomAdapter extends ArrayAdapter<Track>{ private List<Track> items; private Context mContext

I have a RecyclerView in my Fragment and I want to pass data from the Fragment to MyAdapter. Please, tell me if there is any way to do this or if there is a better way to do this. public class Monday extends Fragment { protected RecyclerView mRecyclerView; protected RecyclerView.Adapter mAdapter; protected RecyclerView.LayoutManager mLayoutManager; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.monday, container, false); mRecyclerView = (RecyclerView) rootView.findViewById(R.id.monRecycler)

So I have a custom listview. It's like Instagram layout with 1 image and bunch of buttons in each list items. So here's the problem: I want to implement the share button. To do this, I tried to create a callback from adapter to activity. But it didn't seem to work. Here is what I have so far(I cropped out the unrelated parts): MainActivity public class MainActivity extends ActionBarActivity implements ListAdapter.OnShareClickedListener{ ListView main_list; List<String> url_list; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R

how to modify this imageCheckBoxAdapter code in order to maintain status of checkBox when scrolled(that is all the checkboxes which are checked should remain checked even after scrolling. Also the checked variables need to be stored in an array)? class imageCheckBoxAdapter extends ArrayAdapter<String> { private final Context context; private final ArrayList<String> values; private final Map< String, SmbFile> obj; static ArrayList<Boolean> checks=new ArrayList<Boolean>(); public imageCheckBoxAdapter(Context context,ArrayList<String> values,Map< String, SmbFile>obj) { super(context, R.layout.row
