Just do it like this:

@Override
public void onClick(View v) {
    if( v.getId() == R.id.main_bancada ) {
        // Faça algo para essa View;
    } else if( v.getId() == R.id.main_aguarda ) {
        // Faça algo para essa outra View;
    }

    // Ou então ao invés de usar if, utilize switch case
    switch( v.getId() ) {
        case R.id.main_bancada:
            // Chama algum método;
            break;
        case R.id.main_aguarda:
            // Chama algum método;
            break;
    }
}

Or use anonymous listeners with @Walkim spoke, or set different listeners for each of them. You who know the way you will.
