If there is a scenario where you need your entire application to be in portrait mode or landscape mode or one of the Activity should be in portrait mode and all the other activities should be set at auto screen orientation, then here this article makes you do that in simple steps. So in this article, we are going to learn the following two things.

How to Make the Entire Application to be in Portrait Mode or Landscape Mode?

Here is a preview of an entire application to be in portrait mode:

Step By Step Implementation

Step 1: Create a New Project in Android Studio

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. The code for that has been given in both Java and Kotlin Programming Language for Android. Rename the MainActivity file as Activity1 and activity_main as layout_activity_1 (renaming is done to avoid confusion between two activities).

Note: To rename the file click on the MainActivity -> Right-click -> Refactor -> Rename and similarly do for activity_main file.

Step 2: Create another Empty Activity

Now create another empty activity by right click on the app -> New -> Activity -> Empty Activity and renaming the activity with Activity2 and also renaming the layout name as layout_activity_2. Refer below images if you are unable to get the above steps.

Step 3: Working with the layout_activity_1.xml file

One needs to include text and buttons in the layout_activity_1. So open the layout_activity_1.xml and add widgets TextView and Button as these are been included so that we can differentiate the 2 activities.

Step 4: Working with the Activity1 file

Now you need to handle the above Goto Activity 2 button. So now open Activity1.java and handles the button as invoking the following code. Refer to this for Explicit Intents: Android | Implicit and Explicit Intents with Examples and for handling click events of buttons in android you may refer to this: Handling Click events in Button | Android.

Kotlin

import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
  
class Activity1 : AppCompatActivity() {
    // Invoke the button widget
    var gotoActivity2: Button? = null
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.layout_activity_1)
  
        // Register the button with button ID
        gotoActivity2 = findViewById(R.id.goto_activity_2)
  
        // Set onclick Listener for the button as :
        // So that it can goto Activity2
        gotoActivity2.setOnClickListener(View.OnClickListener {
            val i = Intent(this@Activity1, Activity2::class.java)
            startActivity(i)
        })
    }
}

Step 5:  Working with the layout_activity_2.xml file

Now open the layout_activity_2.xml and add widgets TextView and Button.

Step 6: Working with the Activity2.java file

We need to handle the above Goto Activity 1 button. To handle this button open Activity2.java and invoke the following code:

Java

import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
  
public class Activity2 extends AppCompatActivity {
  
    // Invoke the button widget
    Button gotoActivity1;
  
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        
        // super keyword refers to parent class instance 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_activity_2);
  
        // Register the button with appropriate button ID
        gotoActivity1 = findViewById(R.id.goto_activity_1);
  
        // Set onClick Listener for the button as :
        // So that it goes to Activity1
        gotoActivity1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent i = new Intent(Activity2.this, Activity1.class);
                startActivity(i);
            }
        });
    }
}

                    

Kotlin

import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
class Activity2 : AppCompatActivity() {
    // Invoke the button widget
    var gotoActivity1: Button? = null
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.layout_activity_2)
  
        // Register the button with appropriate button ID
        gotoActivity1 = findViewById(R.id.goto_activity_1)
  
        // Set onClick Listener for the button as :
        // So that it goes to Activity1
        gotoActivity1.setOnClickListener(View.OnClickListener {
            val i = Intent(this@Activity2, Activity1::class.java)
            startActivity(i)
        })
    }
}
