You need to create a bundle and pass the parameter to the second activity:

public void buttonClick(View v) {
    Intent intent = new Intent(Report.this, Map.class);
    intent.putExtra("button", v.getId());
    startActivity(intent);
}

In the second activity:

public class Map extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        int caller = getIntent().getIntExtra("button", 0); 
        switch (caller) {
        case R.id.imageButton1:
            //do something
            break;
        case R.id.imageButton2:
            //do something
            break;
        case R.id.imageButton3:
            //do something
            break;
        case R.id.imageButton4:
            //do something
            break;
        case R.id.imageButton5:
            //do something
            break;
        case R.id.imageButton6:
            //do something
            break;
        }
    }
}

Try:

1. Don't write redundant code, Instead define a common click listener class and assigned the same to every buttons.
2. Put Button name in intent by using putExtra() method of Intent.

For example (2nd step):

Intent intent = new Intent(Report.this, Map.class);
intent.putExtra("WhichButton", "ButtonName");
startActivity();
