Just use ButterKnife library like this:

@OnClick({ R.id.btndoor1, R.id.btndoor2, R.id.btndoor3 })
public void pickDoor(Button door) {
  if (door.hasPrizeBehind()) {
    Toast.makeText(this, "You win!", LENGTH_SHORT).show();
  } else {
    Toast.makeText(this, "Try again", LENGTH_SHORT).show();
  }
}

Where you have to inject the onClick() into the buttons like this

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_example, container, false);
    ButterKnife.inject(this, rootView);

Try this : 

for(int i=0; i < ((ViewGroup)getView()).getChildCount(); i++) {
            View v = ((ViewGroup)getView()).getChildAt(i);
            if(v instanceof Button) {
                v.setOnClickListener(this);
            }
        }

First, create a button array:

Button[] buttons = new Button[number_of_buttons];

Taking into account your ids, you could do the following:

for(int i=0; i<buttons.length; i++)
{
    buttons[i]=(Button)findViewById(getResources().getIdentifier("button"+i,
"id", getPackageName());

    buttons[i].setOnClickListener(this);
}

Set android:onClick="mainMenuButtonClick" to your all buttons in XML and add mainMenuButtonClick() your activity and used switch case to identify Button like:

 public void mainMenuButtonClick(View v) {
    switch (v.getId()) {
        case R.id.Button1:

            break;

        case R.id.Button2:
            break;
        case R.id.crmButton:
            break;
        case R.id.Button3:
            break;

        case R.id.Button4:

            break;

        case R.id.Button5:

            break;
    }

}
