        android:layout_height="wrap_content"
        android:layout_marginTop="5dp"
        android:text="Button One"

Button button = (Button) findViewById(R.id.buttn);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent(MainActivity.this, SecondActivity.class);
        startActivity(intent);
 
    }
});

<RelativeLayout 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"

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
 
        Button button = (Button) findViewById(R.id.buttn);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this, SecondActivity.class);
                startActivity(intent);
