super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

button = (Button) findViewById(R.id.button);

}

@Override
protected void onClick(View view) {

button.setOnClickListener(new View.OnClickListener());
Toast t = Toast.makeText(MainActivity.this, "U Have Clicked Me", Toast.LENGTH_LONG);
t.show();

}

}

import android.view.View;

import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

Button button;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

button = (Button) findViewById(R.id.button);

}

@Override
protected void onClick(View view) {

button.setOnClickListener(new View.OnClickListener());
Toast t = Toast.makeText(MainActivity.this, "U Have Clicked Me", Toast.LENGTH_LONG);
t.show();

}

You missed to set setOnClickListener to button.

   public class MainActivity extends AppCompatActivity implements View.OnClickListener{

   Button button;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);

   button = (Button) findViewById(R.id.button);
   button.setOnClickListener(this); // add this line
  }

  @Override
  protected void onClick(View view) {
    Toast t = Toast.makeText(MainActivity.this, "U Have Clicked Me",Toast.LENGTH_LONG);
    t.show();
  }
}

And also, please format your code nicely so it more readable.
