How to get readable id of layout which send an intent?

how can I get readable id of specyfic layout?

Fragment of my activity_miejsce.xml file:

            <LinearLayout
        android:id="@+id/elementPlace"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:background="@drawable/layout_main_menu_selector"
        android:clickable="true"
        android:onClick="Place">

        ...

    </LinearLayout>

Activity for this layout:

public class PlacesActivity extends AppCompatActivity {

LinearLayout element;

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

    element = (LinearLayout) findViewById(R.id.elementPlace);
}

public void Place(android.view.View v){
    Intent place = new Intent(this, Miejsce.class);
    place.putExtra("source", element.toString());
    startActivity(place);
}}

Miejsce.java (destination of our intent):

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

    Intent src = getIntent();
    String source = src.getStringExtra("source");

    TextView msg = (TextView) findViewById(R.id.napis);
    msg.setText(getIntent().getStringExtra("source"));

    Toast.makeText(getApplicationContext(), "Source: " + source, Toast.LENGTH_SHORT).show();
}

Result (from Toast): Source: android.widget.LinearLayout{14e02738 V.E...C. ...P....0,165-1080,375#7f0c007e app:id/elementPlace}

I want to use id of specyfic layout, because Miejsce.java will generate a layout which will depend on source. For example: There are 3 layouts (hotel, petrol station, restaurant). User had clicked one of them (@+id/restaurant) and intent was sent with id of source (trigger). Java code generated specyfic layout with restaurant.

Thanks for the link @Jackowski. PlacesActivity.java after changes:

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

public void Place(android.view.View v){
    switch(v.getId()){
        case R.id.elementPlace:
            Intent place = new Intent(this, Place.class);
            place.putExtra("source", "elementPlace");
            startActivity(place);
            break;
    }
}

I would say since you know the id name already, You could do something like String id_name = "R.id.id_name" and pass that through your intent.
