ScrollView and Wrap_Content not work - android

I have a problem in my xml, the ScrollView does not work when my RelativeLayout is wrap_content, but if I have a larger screen than the fixed height works correctly, but if I have a larger fixed height than screen the works correctly, but I need to be wrap_content, because I have a listview that is populated gradually as client wants, follows the xml

My listview are configured to not scroll, through code


try do define ScrollView layout_width and layout_height as match_parent, without layout_weight
by the way, you should not mix ScrollView with ListView since both have his own scroll. I suggest to split it like:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
(...)
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>

Insert ImageView in center in Layout in Android

I have created a 4 rectangle layout using LinearLayout and RelativeLayout combination. Now I want to insert an yellow image (profile image) in the center of first two layouts like the image below:
I am not able to do so? Here is what I have tried. This puts up 2 layouts in the beginning properly.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_height="wrap_content"
android:layout_weight=".12"
android:orientation="horizontal"
android:paddingLeft="2dp"
android:paddingRight="2dp"
android:paddingTop="2dp" >
<RelativeLayout
android:id="#+id/profilelayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="1dp"
android:layout_weight=".50"
android:background="#color/light_green"
android:gravity="center" >
<ImageView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/namesysmbol"
android:paddingBottom="5dp"
android:paddingTop="5dp"
android:visibility="visible" />
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/icon"
android:paddingLeft="2dp"
android:text="#string/defaultname"
android:textColor="#color/nametext"
android:textSize="14sp" />
</RelativeLayout>
<RelativeLayout

android:paddingLeft="2dp"
android:text="#string/defaultEmail"
android:textColor="#color/emailtext"
android:textSize="14sp" />
</RelativeLayout>
</LinearLayout>
</LinearLayout>
can somebody help me insert the yellow imageView in the center with the above format.
Thanks!

Can you try use this Layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="170dp">
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#bb4"
android:layout_weight="1"
android:layout_margin="4dp">
</LinearLayout>
<LinearLayout
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#bb4"
android:layout_margin="4dp">
</LinearLayout>
</LinearLayout>
<!-- Your ImageView here!-->
<View
android:layout_centerInParent="true"
android:layout_width="90dp"
android:layout_height="90dp"
android:background="#ff5"/>
</RelativeLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="170dp">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#bb4"
android:layout_weight="1"
android:layout_margin="4dp">
</LinearLayout>
<LinearLayout
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#bb4"
android:layout_margin="4dp">
</LinearLayout>
</LinearLayout>
</LinearLayout>

This the pseudo code but help you to understand the concept
<LinearLayout orientation= vertical>
<FrameLayout>
<LinearLayout orientation= horizontal>
// make to rectangle here
</LinearLayout>
<Image/> create rounded image here with layout_gravity center
</FrameLayout>
<FrameLayout>
<LinearLayout orientation= horizontal>
// make to rectangle here
</LinearLayout>
</FrameLayout>
</LinearLayout>

Copy and paste in your xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#E3E3E3" >

Three children on RelativeLayout does not get place to be shown

I am trying to show four direct children on a Relative Layout where first one is a EdiText (in 'gone' visibility) and second one is LinearLayout with a TextView and ImageView and third is a ListView and fourth is another LinearLayout.
ListView gets over all children. I am posting below the code.

The ListView will go over other elements because you've not given it any relative positions. In a relative layout, every element will be default appear at (0,0) (ie the top left corner of the view) unless it's given a layout_below, layout_alignBottom etc parameter to determine where it's drawn.
So in this case, you 'resumably want the ListView to have android:layout_below="#id/LinearLayout1 and the bottomview similarly android:layout_below="#id/listMessages.

Here is the xml as per your requirement.
<?xml version="1.0" encoding="utf-8"?>

Why aren't my TextViews getting centered?

I'm trying to emulate a dock for a launcher with 3 text views evenly spaced out across said dock... For some reason I can't get my text views to center align with in there parent linear layouts, can someone please explain to me what is my issue here?
Here is my layout in XML:

Try this out, I think you have too many inner layouts.. you can use layout_weight to achieve this.

but the whole layout is scrollable now :(
Is there any way i can make only half the screen scrollable?
PS: android:fillViewport is set to false
UPDATE
I found out why the scroll is not working. it was because the scroll was inside a pull to refresh list view. :(
Looking for a work around for that now

Use layout_weight, here is sample code
<LinearLayout>
<RelativeLayout android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
</RelativeLayout>
<ScrollView android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
<LinearLayout>
<LinearLayout>
</ScrollView>
</LinearLayout>

try to put the layout_weight attribute to divide the screen.
<LinearLayout>
<RelativeLayout android:layout_weight="1">
</RelativeLayout>
<ScrollView android:layout_weight="1">
<LinearLayout>
<LinearLayout>
</ScrollView>
</LinearLayout>

you can try this:
<?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:background="#FFFFFF"
android:orientation="horizontal">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parentt"
android:layout_marginLeft="5dp"
android:background="#ffff"
android:layout_weight="1">
////// Your left side layout content /////////
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="5dp"
android:background="#ffff"
android:orientation="vertical"
android:layout_weight="1">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<LinearLayout
android:scrollbars="vertical"
android:layout_width="wrap_content"
android:orientation="horizontal"
android:layout_height="wrap_content"
>
<TextView
android:id=""
android:layout_marginTop="5dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="20sp" />
</LinearLayout>
</ScrollView>
</LinearLayout>
</LinearLayout>

The scroll view was not working because it was inside a list view that implements the pull to refresh.. Hence the layout changes dont effect.
Sorry everyone, thanks a bunch for the help.

Change your outer layout to RelativeLayout and position yout ScrollView at the parent center. Position other elements in relation to one in center
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal" >
<TextView
android:id="#+id/TextView1"
android:layout_width="151dp"
android:layout_height="fill_parent"
android:textSize="15pt" />
<ScrollView
android:id="#+id/scrollView10"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#000000" >
<TextView
android:id="#+id/textView10"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#000000"
android:gravity="center_vertical"
android:textAlignment="center"
android:textColor="#ffffff"
android:textSize="13sp"
android:textStyle="italic" />
</ScrollView>
</RelativeLayout>

Put the TextView inside of a RelativeLayout, and put that RelativeLayout inside of the ScrollView.
Then, set android:layout_centerInParent="true" within the TextView
