FAB – Floating Action Button

A floating action button (FAB) performs the primary, or most common, action on a screen. It appears in front of all screen content, typically as a circular shape with an icon in its center. FABs come in three types: regular, mini, and extended.

Only use a FAB if it is the most suitable way to present a screen’s primary action.

FloatingActionButton fabButton = findViewById(R.id.fab); // Replace 'fab' with View id

fabButton.setOnClickListener(new View.OnClickListener() { // Set onClickListener
    @Override
    public void onClick(View view) {
        // Create a new intent to start another Activity
        Intent addNewIntent = new Intent(MainActivity.this, NewActivity.class);
        startActivity(addNewIntent);
    }
 });
