How to convert your java application to kotlin

In our last tutorial about “Getting started with Kotlin…” we have learned about setting the environment to work with Kotlin in Android Studio. In this Tutorial, we are going to know how to convert java application or java class to Kotlin. We can convert from java to kotlin very easily whether it is a single class or complete application. We can convert it very easily in android studio by just on some click.

Step 1. Create your project

Project Creation process will be same for both whether you are using Java or Kotlin as explained in our earlier pos
File > New > New Project and select the default Main Activity as per your requirement. By default, all activity will be created in java

Step 2. Convert your project from Java to Kotlin

For converting the Java app into Kotlin application click on the main app folder the click on code menu and then click on convert java file to Kotlin option.

You will see a configure option at right top corner of android studio window as given in below screen shots. We have to click on configure option and follow the rest of the steps as given below.

Then select all Module and press ok. It will take some time and start converting the application. Here, as you can see in below screen shots we can select the all module of single files for conversion.

Now your Java Application is converted into Kotlin. The important thing is that we don't need to any thing with our layout XML files and it can be used as it are getting used with Java

Kotlin Parcelable Array Objects Send To Activity

We know that IPC (Inter Process Communication) between the activity is an extremely important part of any application development. We often required that we need to send some data to other activity. For example, we may be required to send an array of data, data could be an Integer, String, Long, Double, Float or any other custom data objects. So, In this example, we are going to learn how to implement the Kotlin Parcelable Array object to send the data from one activity to second activity. What is Parcel? The parcel class is designed as a high-performance IPC transport. A Parcel can contain both flattened data that will be unflattened on the other side of the IPC, and references to live IBinde r objects that will result in the other side receiving a proxy IBinder connected with the original IBinder in the Parcel. Create Kotlin Parcelable Array Objects Parcelable is API for placing the arbitrary objects into the Parcel. In Actual in android app development, Parcelable is an interface

Create Custom EditText View in Android

We use the EditText for taking the input from the user and use it at several places in our project. We required to do lots of customization for each time and there are lots of redundant code we write. Writing and managing these redundant codes is very difficult for example if we want to change the look and feel of the view them we need to modify it at each place where our EditText is getting used. So to avoid these kinds of the problem we can create our own Custom EditText View by just. The EditText view is just an extension of the TextView with lots of editing option and properties that required for the user input. How To Create Custom EditText View For creating the Custom EditText we need to extend the AppCompatEditText and override all three constructors of the view as given below. import android.content.Context; import android.graphics.Typeface; import android.support.annotation.Nullable; import android.support.v7.widget.AppCompatEditText; import android.util.AttributeSet; public
