First of all take a look on code below , i have got an Intent to change activity on Click Listner.
Intent changeActivity = new Intent(MainActivity.this, MainActivity2.class); startActivity(changeActivity);
Let’s tear down the above code and know about how to make an Intent for changing activities in android in depth.
Step 1: Import the Intent class, it will be automatically imported when you write down the word Intent.
Step 2: Name your Intent whatever you want it to be, then place equal to sign then use new Intent method to initialize the Intent.
Step 3: Now Name the Activity from which you want to move. If it is MainActivity, then write down MainActivity.this. Whatever be the name of your activity you have to write the same with .this keyword after that name.
Step 4: Now place comma sign(,) after .this keyword then name the activity on which you want to move, if it is MainActivity2 then write down MainActivity2.class. Whatever be the name of your activity you have to write the same with .class keyword after that name.
Step 5: Now, start the Intent using keyword startActivity(). Place the name of Intent in brackets of this method.
Let’s Make a Layout with one button, clicking that button will change or switch the Activity.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Swtich to activity 2"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>Now let’s put the Intent which we created earlier in the click event listener.
MainActivity.java
package com.startechcity.switchactivity;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent changeActivity = new Intent(MainActivity.this, MainActivity2.class);
startActivity(changeActivity);
}
});
}
}Result for Android switch activity
