Android & React-Native Example

Dummy Data / Sample Data :   Many times while developing the application we need to check the UI before it actually renders on the device screen. In android, if you are using recycler-view or list-view, then it is very hard to check the UI. Sample data is a set of model data to help the developer to see the design without a run the code into the device and also does not require any code to see the output. You can verify the result you see is only visible in the design section and not visible into the device.  The main advantage is that it reflects instantly in the preview section so that you don’t want to run the build to check the result which saves  a lot of development time.  Add the below tag into your XML file. activity_main.xml                       <LinearLayout   xmlns:tools="http://schemas.android.com/tools" >    ...

RecyclerView is used to show the list of items. If you have more than one with the same layout then you can use recyclerview. It has many benefits but the most important one is it only renders the item which is visible to the user.  This example will check how can we work with the recycler view in the android application and implement the click-listener for the item. Gradle Changes:- Add this Gradle to your project  compile 'com.android.support:recyclerview-v7:+' The thing, we are going to perform:- 1) First add the Gradle file in your project to use the recycler view. 2) Create one layout file and add the text view to show data. 3) Create one new java file for the recycler adapter. 1) Let's add the recycler-view in the XML file. <RelativeLayout >     <android.support.v7.widget.RecyclerView         android:layout_width="wrap_content"           android:layout_height="wrap_content"  ...
