Create one listener for multiple buttons:

OnClickListener listener1 = new OnClickListener() {
        @Override
        public void onClick(View v) {
            // some code
        }
};

button1.setOnClickListener(listener1);
button2.setOnClickListener(listener1);
button3.setOnClickListener(listener1);
button4.setOnClickListener(listener1);


OnClickListener listener2 = new OnClickListener() {
        @Override
        public void onClick(View v) {
            // some code
        }
};

button5.setOnClickListener(listener2);
button6.setOnClickListener(listener2);
button7.setOnClickListener(listener2);
button8.setOnClickListener(listener2);

or use switch in listener, like this:

@Override
public void onClick(View button) {
   switch (button.getTag())(
       case 'button1':
       case 'button2':
       case 'button3':
           // do something
           break;
       case 'button4':
       case 'button5':
       case 'button6':
           // do anotherthing
           break;          
   }
}

As Abhishek Kumar said, you can set listeners to button at xml:

android:onClick="onClick"

You can also set it in your layout xml using the android:onclick attribute.

ie. for first 4 Buttons

android:onClick="onClickGroup1"

Then in your activity class add the onClick method.

public void onClickGroup1(View v) {
...

I would make the Activity implement an OnClickListener

public class MainAcivity extends AppCompatActivity implements View.OnClickListener {
    private Button buttonOne
    private Button buttonTwo
    ...

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

        Button buttonOne = (Button) rootView.findViewById(R.id.buttonOne);
        Button buttonTwo = (Button) rootView.findViewById(R.id.buttonTwo);
        ...


        buttonOne.setOnClickListener(this);
        buttonTwo.setOnClickListener(this);
        ...
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.buttonOne:
                // do something
                break;
            case R.id.buttonTwo:
                // do something
                break;
        }
    }
}

You can easily have one case for multiple buttons then.
