Page Redirect using Intent-AGN HUB

Steps:

1. Create Two Activities:

• Let's assume we have MainActivity (source activity) and SecondActivity (destination activity).

2. Define Activities in AndroidManifest.xml: Ensure both activities are registered in the manifest.

3. <activity android:name=".MainActivity" />

4. <activity android:name=".SecondActivity" />

5. Set Up the Button in the Layout: In activity_main.xml (layout file for MainActivity), add a button.

6. <Button

7.     android:id="@+id/buttonRedirect"

8.     android:layout_width="wrap_content"

9.     android:layout_height="wrap_content"

10.     android:text="Go to Second Page"

11.     android:layout_gravity="center" />

12. Implement the Intent in MainActivity: Use an Intent to navigate to SecondActivity.

13. import android.content.Intent

14. import android.os.Bundle

15. import android.widget.Button

16. import androidx.appcompat.app.AppCompatActivity

17. 
    

18. class MainActivity : AppCompatActivity() {

19.     override fun onCreate(savedInstanceState: Bundle?) {

20.         super.onCreate(savedInstanceState)

21.         setContentView(R.layout.activity_main)

22. 
    

23.         // Find the button

24.         val buttonRedirect: Button = findViewById(R.id.buttonRedirect)

25. 
    

26.         // Set a click listener to redirect to SecondActivity

27.         buttonRedirect.setOnClickListener {

28.             val intent = Intent(this, SecondActivity::class.java)

29.             startActivity(intent)

30.         }

31.     }

32. }

33. Create the Destination Activity: Create a new activity called SecondActivity.

34. import android.os.Bundle

35. import androidx.appcompat.app.AppCompatActivity

36. 
    

37. class SecondActivity : AppCompatActivity() {

38.     override fun onCreate(savedInstanceState: Bundle?) {

39.         super.onCreate(savedInstanceState)

40.         setContentView(R.layout.activity_second)

41.     }

42. }

43. Set Layout for SecondActivity: Create a layout file activity_second.xml.

44. <TextView

45.     android:layout_width="wrap_content"

46.     android:layout_height="wrap_content"

47.     android:text="Welcome to Second Page!"

48.     android:layout_gravity="center"

49.     android:textSize="18sp" />

Explanation:

1. Intent: Used to start a new activity. It requires:

• Current context (this).

• The class of the destination activity (SecondActivity::class.java).

2. startActivity(intent): Starts the new activity.

---

Result:

When you click the button in MainActivity, it will navigate to SecondActivity, displaying the message "Welcome to Second Page!".
