Name any three-layout manager in android studio?

Android Studio provides several layout managers that developers can use to create the user interface of their Android applications. Here are three commonly used layout managers:

• LinearLayout: LinearLayout arranges views in a linear manner, either horizontally or vertically. This is the simplest layout manager, and it is often used to create simple user interfaces with a single row or column of views.
  


• RelativeLayout: RelativeLayout arranges views relative to each other, using rules to position and align them. It is more flexible than LinearLayout and can be used to create more complex user interfaces.
  


• GridLayout: GridLayout arranges views in a grid of rows and columns. It allows developers to specify the number of rows and columns, as well as the size and spacing of each cell. This layout manager is often used to create table-like structures, such as calendars or grids of images.

These are just a few examples of the layout managers available in Android Studio. Other layout managers include ConstraintLayout, FrameLayout, and TableLayout, each with their own unique features and advantages. By using different layout managers, developers can create a variety of user interfaces that are optimized for different screen sizes and orientations.

Programming Code:

Following code write in: MainActivity.java

package com.go2collage.practical_03;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

Following code write in: activity_main.java
