Android: Use a SWITCH statement with setOnClickListener/onClick for more than 1 button?

Let's say I have a few buttons in a LinearLayout, 2 of them are:

mycards_button = ((Button)this.findViewById(R.id.Button_MyCards));
exit_button = ((Button)this.findViewById(R.id.Button_Exit));

I register setOnClickListener() on both of them:

mycards_button.setOnClickListener(this);
exit_button.setOnClickListener(this);

How do I make a SWITCH to differentiate between the two buttons within the Onclick ?

public void onClick(View v) {
  switch(?????){
    case ???:
      /** Start a new Activity MyCards.java */
      Intent intent = new Intent(this, MyCards.class);
      this.startActivity(intent);
      break;
    case ???:
      /** AlerDialog when click on Exit */
      MyAlertDialog();
      break;
}

I make it simple, if the layout is same i just put the intent it.

My code like this:

public class RegistrationMenuActivity extends AppCompatActivity implements View.OnClickListener {


    private Button btnCertificate, btnSeminarKit;

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

        initClick();
    }

    private void initClick() {
        btnCertificate = (Button) findViewById(R.id.btn_Certificate);
        btnCertificate.setOnClickListener(this);

        btnSeminarKit = (Button) findViewById(R.id.btn_SeminarKit);
        btnSeminarKit.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btn_Certificate:
                break;
            case R.id.btn_SeminarKit:
                break;
        }
        Intent intent = new Intent(RegistrationMenuActivity.this, ScanQRCodeActivity.class);
        startActivity(intent);
    }
}

For my example :first 'MainActivity' implements 'View.OnClickListener' than start the code ....

@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    init();}


public void init(){

    foryou = (Button) this.findViewById(R.id.btn_foryou);
    following = (Button) findViewById(R.id.btn_following);
    popular = (Button) findViewById(R.id.btn_popular);
    watching = (Button) findViewById(R.id.btn_continuewatching);
    mProgress = (ProgressBar) findViewById(R.id.pb);

    foryou.setOnClickListener(this);
    following.setOnClickListener(this);
    popular.setOnClickListener(this);
    watching.setOnClickListener(this);
    mProgress.setOnClickListener(this);
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.btn_foryou:
            foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_following:
            following.setPaintFlags(following.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_popular:
            popular.setPaintFlags(popular.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_continuewatching:
            watching.setPaintFlags(watching.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        case R.id.btn_5:
            // foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

            break;
        default:
            foryou.setPaintFlags(foryou.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

    }
}

there's another good way and it doesn't wast your time

create the methode to do whatever you want for example like this in your activity

public void replaceSuggest(View v) {
        optionPanel.setVisibility(View.VISIBLE);
        replaceWith.setVisibility(View.VISIBLE);
        searchEdit.setText(selected);

    }

after creating your methode go to the xml view layout and put like this (in the view you want to apply this action, example here is the TextView will perform the click :

 <TextView
                        android:id="@+id/anyId"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:text="@string/replace"
                        android:textColor="#ffffff"
                        android:gravity="center_vertical"
                        android:paddingLeft="8dp"
                        android:paddingRight="4dp"
                        android:textSize="12dp"
// here you write the methode name after onClick
                        android:onClick="replaceSuggest"/>
