Answer 1

In xml add the following to the button

android:onClick:"onClick"

Then in your activity:

public void onClick(View view)
{
    Intent i = new Intent(CurrentActivity.this,NextActivity.class);
    startActivity(i);
}

Answer 2

You can register a listener in your code as well:

    Button button = (Button) findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            startActivity(new Intent(getApplicationContext(), MyActivity.class));
        }
    });

Answer 3

You need to setOnClickListener on the Floating Action Button, you can do that by implementing View.OnClickListener to your ActivityA.

Then simply start a new intent, add the below code to your ActivityA, inside the onClickListener of the Floating Action Button.

Intent i = new Intent(getApplicationContext(), ActivityB.class);
startActivity(i);

Answer 4

put this code in onclick of button

Intent intent = new Intent(this, B.class);
startActivity(intent);
