android recycleview and fragment

Creating Android Recycleview is pretty straight forward. All I need to do is :-

a) Setup Adapter

b) Set Layout


Let's walk through the process. First we need to include proper information in gradle



Then we need to layout our recycleview



Now lets create some adapter.



Noticed that we our adapter contains a view holder - just think of viewholder as your android row level layout file that has been inflated.
We are able to get a reference to our control as shown in the code below :-

public ViewHolder(View itemView) {
    super(itemView);    title = (TextView) itemView.findViewById(R.id.title);    description = (TextView) itemView.findViewById(R.id.description);    fullNews = (TextView) itemView.findViewById(R.id.fullNews);}


To get it to work we need the code below. All we need here is to configure data adapter and set our layout. Here, I am using DividerItemDecoration that comes with Android.

recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);adapter = new NewsDataAdapter(news);RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getContext());
recyclerView.addItemDecoration(new DividerItemDecoration(getContext(), LinearLayoutManager.VERTICAL));recyclerView.setLayoutManager(layoutManager);recyclerView.setAdapter(adapter);recyclerView.setItemAnimator(new DefaultItemAnimator());


For a complete list of the project, please go here.

Android Programmatically apply style to your view

Applying style to your view (button in this case) dynamically is pretty easy. All you have to do is place the following in your layout folder (res/layout)
Let's call this file : buttonstyle.xml
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" > <shape> <solid android:color="#449def" /> <stroke android:width="1dp" android:color="#2f6699" /> <corners android:radius="3dp" /> <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" /> </shape> </item> <item> <shape> <gradient android:startColor="#449def" a…

OpenCover code coverage for .Net Core

I know there are many post out there getting code coverage for .dotnetcore. I'm using opencover to address this needs.

In case, you do no want to use opencover and wanted to stick with vs2015 code coverage, you can try to copy Microsoft.VisualStudio.CodeCoverage.Shim.dll from C:\Program Files (x86)\Microsoft Visual Studio 14.0\Team Tools\Dynamic Code Coverage Tools\coreclr\ and drop it into your project "bin\Debug\netcoreapp1.0" folder.  Please note : you need to be on VS2015 Enterprise to do this. 

To get started, I guess we need to add OpenCover and ReportGenerator for our test projects, as shown in diagram below :-



When nuget packge gets restored, we will have some binaries downloaded to our machine and we going to use this to generate some statistics. I think the biggest issue is to getting those command lines work.

In dotnetcore, we run test project using "dotnet test" (assuming you are in the test project folder - if not please go there)  So we add this …

I have problem locating my AsEnumerable extension method in my DataTabe (System.Data). Thank god for this post by Angel

I was able to find this method once i have added reference to the following assembly.

C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\System.Data.DataSetExtensions.dll

Try to do a dummy Build and you should be able to get it.
