android - Error in a resource

Question

Sorry, the error is another one. It is in the ImageButton. But the issue is fixed now. That's why I change it for R.id.none. But when I change it for the right name, I thought it wouldn't run but it runs. Very strange.

    imgbutton = (ImageButton) findViewById(R.id.none);

    imgbutton.setOnClickListener(new OnClickListener() {

            @Override
        public void onClick(View arg0) {

        Toast.makeText(Insertarlugar.this, "ImageButton is clicked!", 
                    Toast.LENGTH_SHORT).show();

          }

    });
}

    @Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.insertarlugar, menu);
    return true;
}

 }
