Answer 1

Caused by: java.lang.NullPointerException - at com.project.places.First_Page.onViewCreated(First_Page.java:36

In your onViewCreated() you should access the fragment UI views with view.findViewById() instead of getActivity().findViewById(). The fragment isn't attached to the activity yet so it's not found in the activity's view hierarchy either.

Answer 2

You need to use

android:name = "com.project.places.First_Page"

instead of

class = "com.project.places.First_Page"

Answer 3

<fragment 
    android:id="@+id/fragment_id"
    android:name="com.example.xxx.fragment.FragmentClassName"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    tools:layout="@layout/fragment_layout" />

Try to add android:name for your xml fragment:).It works to me.

Answer 4

I gets this error when tried to put the Activity to constructor like this:

public MyView (Activity activity) {
   super (activity);
}

public MyView (Activity activity, AttributeSet attrs) {
    super (activity, attrs);
}

Remember that you can only put a Context in custom views constructors like this:

public MyView (Context context) {
   super (context);
}

public MyView (Context context, AttributeSet attrs) {
    super (context, attrs);
}
