LinearLayout is a simple and flexible layout manager that arranges its children either horizontally or vertically, based on the orientation set. Here's an example of using LinearLayout in an Android XML layout file:

Here is the tutorial for Java

Step 1:

File open res/layout/activity_main.xml file −

    </LinearLayout>


</RelativeLayout>

Open Device Manager, run the emulator, and then run the application. Next, check the working output and check the output you declared in your code.
