Android-Last item of the ListView is not visible

I have added the ListView inside ViewPager, as soon as the page is loaded the first tab is selected and the last item of the list does not show up for the first time, its becoming visible when I go to next tab and come back. I would like to see all the items of the listview when its loaded for the first time. Please help me to fix this problem.
This is the xml for the listview -
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/listview_categories"
android:layout_width="fill_parent"
android:divider="#color/light_gray_a1"
android:dividerHeight="0.667dp"
android:background="#color/white"
android:layout_height="fill_parent" />
</RelativeLayout>

add bottom padding like this and change fill_parent to match_parent
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/listview_categories"
android:layout_width="match_parent"
android:divider="#color/light_gray_a1"
android:dividerHeight="0.667dp"
android:paddingBottom="40dp"
android:background="#color/white"
android:layout_height="match_parent" />
</RelativeLayout>

I had this issue. Just now I solved it. Look for android:layout_weight in all the Layouts you used and if it is set some non zero values like android:layout_weight="1" or android:layout_weight="0.91", then set them to zero like this,
android:layout_weight="0"

Video background on entire screen

I want to have a video background on my entire screen. Everything works correctly in java: it loops etc. The problem might be in xml.
Currently I have video on a top of the screen, it looks like this: (Video is perfeclty fitted in edges)
While my purpose is to have it entirely in my screen:
Please what should i make my xml look like to achieve my goal. Thanks.
XML:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/home_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<VideoView
android:id="#+id/surface"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</FrameLayout>

First you need to set the orientation to landscape since you said you purpose is in landscape mode
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); // add it below super.oncreate
If this code not working check out this link
or your could set the orientation in manifest just google it
And change this in your xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/home_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<VideoView
android:id="#+id/surface"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
/>
</FrameLayout>

Android : put listfragment inside xml layout

ListFragment by defaults shows a progressbar while the data get loaded. I plan on putting the listfragment in xml file and have it show progressbar till I get the data from the server.
The reason I m trying to put listfragment inside xml is because in my layout I have a linearlayout above the place where I plan to put listfragment.
Here is my xml file.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<LinearLayout
android:id="#+id/filterHolder"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#color/white"
>
<ToggleButton
android:id="#+id/filterToggleButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/white"
android:textColor="#color/black"
android:textOff="#string/filterToggleButtonText"
android:textOn="#string/filterToggleButtonText"
android:drawableLeft="#drawable/filter_small"
/>
</LinearLayout>
<fragment
andorid:name="in.coupondunia.androidapp.testListFragment"
android:id="#+id/couponsByCategoryFragment"
android:layout_below="#id/filterHolder"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</RelativeLayout>

Have you tried using http://developer.android.com/reference/android/app/ListFragment.html#setListShown(boolean) with parameter true? From the docs it might work.

Empty text view message when listview is empty

I have a ListView with an empty list catch in the XML and it works fine. How to toggle ListView Empty Text please ?
This is my XML code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/empty"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/emptyList" />
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
I'm not using a ListActivity. It s possible to do that please ?

You just need to make use of setEmptyView(View v):
person_ListView.setEmptyView(root.findViewById(R.id.empty));
offtopic: ListActivity is using this method also, but with android.R.id.empty.

Understanding XML attributes for custom packages

I'm trying to use the drag/drop functionality from this fine project: https://github.com/bauerca/drag-sort-listview/
First, I've added the library using the instructions on GitHub.
Second, I'm trying to use the XML declaration. This is my main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:dslv="http://schemas.android.com/apk/res/com.mobeta.android.dslv"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<include layout="#layout/header"/>
<com.mobeta.android.dslv.DragSortListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#D9D9D9"
android:dividerHeight="2dp"
android:listSelector="#drawable/list_selector"
dslv:drag_enabled="true"
dslv:drag_scroll_start="0.33"
dslv:drag_start_mode="onDown"/>
</LinearLayout>
But, Eclipse is throwing this error: No resource identifier found for attribute 'drag_enabled' in package 'com.mobeta.android.dslv'; similarly for 'drag_scroll_start' and 'drag_start_mode'.
I'd like to understand on a more general level what I'm doing wrong here. And if anyone can give me specific help for using this library, I'd appreciate that as well.

Since you are refering the attributes fro your library instead of giving the full path of the library give "res-auto"
please see the change
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:dslv="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<include layout="#layout/header"/>
<com.mobeta.android.dslv.DragSortListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#D9D9D9"
android:dividerHeight="2dp"
android:listSelector="#drawable/list_selector"
dslv:drag_enabled="true"
dslv:drag_scroll_start="0.33"
dslv:drag_start_mode="onDown"/>
