Android - Listview not showing the last item

Question

My Problem is the last item in the listview is not displaying even though it has been added to the adapter and as well as in the list as i can see the number of items in the adapter is ok. Is it the problem with the layout? this is my layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/golive_bg"
android:orientation="vertical" >

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <EditText
        android:id="@+id/Room"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ems="10" >

        <requestFocus android:layout_width="wrap_content" />

    </EditText>

    <Button
        android:id="@+id/Search1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Search" />

    <ImageButton
        android:id="@+id/CreateRoomimageButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/closed_doorplus" />
</LinearLayout>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >
        <ListView
            android:id="@+id/listRooms"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fastScrollEnabled="true"
            android:transcriptMode="alwaysScroll">
        </ListView>
</LinearLayout>

</LinearLayout>

This is my class activity

public void setRoomName(String roomName) {

public static Collection<HostedRoom> getHostedRooms(Connection connection, String serviceName)
                throws XMPPException {
            List<HostedRoom> answer = new ArrayList<HostedRoom>();
            ServiceDiscoveryManager discoManager = new

            DiscoverItems items = discoManager.discoverItems(serviceName);
            for (Iterator<DiscoverItems.Item> it = items.getItems(); it.hasNext();) {

            }
            return answer;
        }   

}

And this is my custom adapter

public class ChatRoomListAdapter extends ArrayAdapter<ChatRoom> {

private TextView name;
private static List<ChatRoom>  ChatRoom = new ArrayList<ChatRoom>();
private LinearLayout wrapper;
private ImageView lock;
public ChatRoomListAdapter(Context context, int textViewResourceId) {
    super(context, textViewResourceId);
}


public static List<ChatRoom> getChatRoom() {
    return ChatRoom;
}


public static void setChatRoom(List<ChatRoom> chatRoom) {
    ChatRoom = chatRoom;
}


public ChatRoom getItem(int index) {
    return ChatRoomListAdapter.ChatRoom.get(index);
}

public static String getItemName(int index) {
    return ChatRoomListAdapter.ChatRoom.get(index).name;
}


public static void setfriends(List<Friends> friends) {
    FriendListAdapter.setFriends(friends);
}

public void add(ChatRoom object) {
System.out.println("IN Chat room list adapter "+" addded");
ChatRoomListAdapter.ChatRoom.add(object);
    super.add(object);

}

public void remove(ChatRoom object) {
    ChatRoom.remove(object);
    super.remove(object);
}

public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    if (row == null) {
        LayoutInflater inflater = (LayoutInflater)     
this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.chat_rooms_wrapper, parent, false);
    }

    wrapper = (LinearLayout) row.findViewById(R.id.C_R_wrapper);

    name = (TextView) row.findViewById(R.id.C_R_RoomName);
    lock=(ImageView)row.findViewById(R.id.C_R_Lock);

    try {
         Log.d("Chat room adapter", "heere");
         ChatRoom CR= getItem(position);
         System.out.println("name= "+CR.name);
         name.setText(CR.name);

            if(CR.lock==true)
            {
                lock.setImageResource(R.drawable.lock_lock_icon);
            }else{
                lock.setImageResource(R.drawable.lock_unlock_icon);
            }


    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }   



return row;

}


public Bitmap decodeToBitmap(byte[] decodedByte) {
    return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length);
}



}

Thanks in advance.

Answer 1

Add this line to your Viewpager

android:layout_marginBottom="?attr/actionBarSize"

because the size you don't have at the bottom is exactly the size taken by your Toolbar

Example with RecyclerView

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view_trips"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical"
    android:layout_marginBottom="?attr/actionBarSize"/>

Example with Viewpager

<android.support.v4.view.ViewPager
    android:id="@+id/viewpager_trip_history"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="?attr/actionBarSize" />
