@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.event_detail, container, false);

    return v;

}

}

fragment_layout...

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@color/bg"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imgEventCover"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:adjustViewBounds="true"
        android:src="@drawable/imagemapoio2" />

    <TextView
        android:id="@+id/txtEventDetail"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/txtEventInfo"
        android:layout_centerVertical="true"
        android:text="LXFACTORY   |   2km"
        android:textColor="@android:color/black" />

    <TextView
        android:id="@+id/txtEventInfo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/txtEventDetail"
        android:layout_centerHorizontal="true"
        android:text="Playground present Drum&amp;Bass in the Factory"
        android:textColor="@color/dk" />

    <ImageView
        android:id="@+id/imgTiming"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_below="@+id/txtEventTime"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="25dp"
        android:src="@drawable/yellowtiming" />

    <TextView
        android:id="@+id/txtEventTime"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/txtEventDetail"
        android:layout_below="@+id/txtEventInfo"
        android:layout_marginTop="5dp"
        android:text="22.00H - 04.30H"
        android:textColor="@color/dk"
        android:textSize="10dp" />

</RelativeLayout>

Main activity...(method to change values)

public void initializeEvent() {
    Fragment fr = new EventDetail();
    FragmentManager fm = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fm.beginTransaction();
    View v = fr.getView();

    //get fragment elements.

    fragmentTransaction.replace(R.id.fragment_menu, fr);
    fragmentTransaction.commit();
}

How can i get the textviews and imageviews from this fragment to set their images and text?

It's Fragment's layout and you should set it from within Fragment. Any special reason why you want to do it from your Activity? — Sharjeel, Feb 21 '14 at 02:36
I've a list in my activity and when I click in one item it display a fragment with some data about that item. So that data should be dynamic. — Pedro Simão, Feb 21 '14 at 02:47

You shouldn't set any values directly via method either from Activity or Fragment.

From Activity to Fragment,

You should add appropriate values in the bundle which you can send via setArguments(bundle), and in fragment you can later retrive those values via getArguments()

From Fragment to Activity,

You should create an interface and use its method to pass the values from Fragment to Activity
