OnClick in fragment without creating tons of onclicklisteners

How can I handle an OnClick method in a fragment without making a ton of onclick listeners for each button and then having a huge switch statement for them. For example, I have 10 checkboxes in my layout and I want the fragment to handle them all in the same way (have the same OnClick)

First of all, your question is ambigue. It is not 100% clear what you want to know.

If I understand correctly you do not want 10 seperate listeners, but only 1.

Then you get:

public class Main2Activity extends AppCompatActivity implements View.OnClickListener{
    private Button button01;
    private Button button02;
    private Button button03;
    private Button button04;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);

        button01 = (Button) findViewById(R.id.button01);
        button02 = (Button) findViewById(R.id.button02);
        button03 = (Button) findViewById(R.id.button03);
        button04 = (Button) findViewById(R.id.button04);

        button01.setOnClickListener(this);
        button02.setOnClickListener(this);
        button03.setOnClickListener(this);
        button04.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        if (view == button01) {
            // button01 clicked
        } else if (view == button02) {
            // button02 clicked
        } else if (view == button03) {
            // button03 clicked
        } else if (view == button04) {
            // button4 clicked
        }
    }
}

Is this what you were looking for?

Its pretty easy. Just do it like this if you want to handle them same way;

        View.OnClickListener listener = new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                Toast.makeText(MainActivity.this,"asdasd",Toast.LENGTH_SHORT).show();
            }
        };
        item1.setOnClickListener(listener);
        item2.setOnClickListener(listener);
        item3.setOnClickListener(listener);
