Switch between Activities in Android - Best Step by Step Guide

This example demonstrates how to switch between different Activities in Android. Create a new project . Here we need two Activities to switch between. Add these following code to MainActivity.java

public class MainActivity extends AppCompatActivity {

    Button click_first_btn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        click_first_btn = findViewById(R.id.click_first_btn);
        click_first_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                 Intent i = new Intent(getApplicationContext(),SecondActivity.class);
                 startActivity(i);
            }
        });
    }
}

Now create another Activity and named that SecondActivity.java. Add this code to that

public class SecondActivity extends AppCompatActivity {

    Button click_second_btn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
        click_second_btn = findViewById(R.id.click_second_btn);
        click_second_btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(SecondActivity.this,MainActivity.class);
                startActivity(i);
            }
        });

    }
}

<?xml version="1.0" encoding="utf-8"?>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Im First Activity" />

    <Button
        android:id="@+id/click_first_btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click to go Second"/>

</LinearLayout>
