Android: findviewbyid: finding view by id when view is not on the same layout invoked by setContentView

android, layout

Solution

Thanks for commenting, I understand what you mean but I didn't want to check old values. I just wanted to get a pointer to that view.

Looking at someone else's code I have just found a workaround, you can access the root of a layout using `LayoutInflater`.

The code is the following, where `this` is an Activity:

final LayoutInflater factory = getLayoutInflater();

final View textEntryView = factory.inflate(R.layout.landmark_new_dialog, null);

landmarkEditNameView = (EditText) textEntryView.findViewById(R.id.landmark_name_dialog_edit);

You need to get the inflater for `this` context, access the root view through the inflate method and finally call `findViewById` on the root view of the layout.

Hope this is useful for someone! Bye

Problem

I have an activity MyActivity that extends from MapActivity. In the .xml file containing the layout I can only include the MapView ``` <com.google.android.maps.MapView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/trail_map_view" android:layout_width="fill_parent" android:layout_height="fill_parent" android:clickable="true" android:apiKey="key" /> ``` However I do need to find another view that is located in another .xml file. Unfortunately, findViewById returns null. How can I get the view I am looking for? Thanks a lot!
