I have the below layout which contain mainly:
Relative layout, which act as header with Textview and button.
and Listview.
I would like to make the "header" which is the above relative layout to be transparent and show the listview as user scroll down the list view.
I know how to make the layout transparent, but I dont know how to show the listview as background for the "header".

You are using a LinearLayout as the root container and in linear layout the views are placed one over the other so you cannot overlap one view over the other. If you want an overlapping effect you can use either the FrameLayout or the RelativeLayout as the root container.
Using RelativeLayout is a better option.
Here is sample code for this:
<?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:orientation="vertical" >
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
<Button
android:id="#+id/view"
android:layout_width="fill_parent"
android:layout_height="100dp"
android:background="#00cc0000"
android:layout_alignParentTop="true" />
</RelativeLayout>
Here the button is overlapping the list view.
I hope this will help :)
Try moving the ListView inside of your RelativeLayout, as the first element (this ensures that it's in the back). This way, the other views are just on top of the ListView, and if you make them transparent you should get the desired effect!
Oh, and you should make the ListView then fill the RelativeLayout:
<ListView
android:id="#+id/mylist1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true" >
</ListView>
, and make the RelativeLayout fill the screen:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/buttonlayout2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
...

The contents of my list view get hidden behind the button as follows:

The TextView for each row is as follows:

android:layout_width="fill_parent"
android:layout_height="wrap_content
android:layout_gravity="right"
android:gravity="right"

/>
What should i do to align it properly (as in above the button)?
Also when the listView is with just one or two entries, and when the keyboard is opened to type, the whole view shifts? How do I fix that as well? Thanks in advance
Cleaned up and corected the code a bit. Perhaps this is what you were looking for. Let me know if it works. Cheers !

adding android:layout_above="#+id/InnerRelativeLayout" to your ListView.
RelativeLayout has child views specify their position relative to the parent view or to each other (specified by ID). So you can align two elements by right border, or make one below another, centered in the screen, centered left, and so on. By default, all child views are drawn at the top-left of the layout, so you must define the position of each view using the various layout properties available from RelativeLayout.LayoutParams.
For put your InnerRelativeLayout layout at Top add android:layout_alignParentTop="true" to your InnerRelativeLayout and remove android:layout_alignParentBottom="true"
Update: set up your Layout like below:
<?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/Beige "
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/InnerRelativeLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" >
<Button
android:id="#+id/Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:onClick="addItems"
android:text="Send" >
</Button>
<EditText
android:id="#+id/message"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#id/Button"
android:hint="Enter text" >
</EditText>
</RelativeLayout>
<ListView
android:id="#+id/list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/InnerRelativeLayout"
android:drawSelectorOnTop="false" />
</RelativeLayout>
Output:
use android:layout_above="#+id/InnerRelativeLayout" in your listview
Make the outer RelativeLayout into a LinearLayout with orientation vertical. Then, for the ListView set layout_height as 0dp and layout_weight as 1. The ListView will fill up all the remaining space in the LinearLayout without overlapping other views.
Also, stop using fill_parent, it's been deprecated and you should use match_parent instead.
I have a LinearLayout (vertical) and it should contain 3 elements in the following order: textview, listview and button. The listview could be really high so in order to keep all the 3 elements visible I put the 3 elements each one inside another layout. So my structure is like:
linear layout (vertical)
linear layout (horizontal)
textview
linear layout (vertial) *
listview
relative layout
button
In order to get it working I set a fixed height to the vertical linearlayout which only contains the listview (*) but I know it is a bad choice because on bigger devices there will be a lot of empty space. How can I fix it?
thanks
User percentage values for the LinearLayout(*), so they take up a percentage of the parent's height,
and for the rest, if you want them to take up remaining space, add attribute: android:layout_weight:1;
Implement your layout this way :
<RelativeLayout 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_alignParentTop="true"
android:gravity="center"

android:text="Header Text" />
<ListView
android:id="#+id/mListView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/mButton"
android:layout_below="#+id/mTextView" >
</ListView>
<Button
android:id="#+id/mButton"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

I have given margin top attribute for the ListView, but even though it overlaps on the Button and EditText controls.
I am using a FrameLayout but of no use. Please suggest me any help!!
Any help is appreciated!!
You should use LinearLayout as parent, just set android:orientation="vertical".
<?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" >
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"
android:src="#drawable/pattern1" />
<LinearLayout
android:id="#+id/LinearLayout02"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="top" >
...
</LinearLayout>
<ListView
android:id="#+id/list_customers"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="bottom|center_horizontal" >
...
</ListView>
</LinearLayout>
FrameLayout has no 'rules of placement' so everything just stacks on to each other.
Instead, use a LinearLayout with android:orientation="vertical"
or use a RelativeLayout and add positioning values to the childs, such as android:layout_below
+1 Neoh and remove imageview, instead put the image as background image attribute at parent view
android:background="#drawable/pattern1"
FrameLayout are used very less,beacuse they are used to display single view or views which overlaps each other.
So you should use RelativeLayout.
FrameLayout is not the best option. You can use other layouts, eg, GridLayout, RelativeLayout or ListView.
i want to create a screen like this on the android :
and achieving this, i write some codes like that.. But i didn't do what i want. The text area doesn't exist in the screen. What should i do ? Any opinion.. thank you in advance..

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello, I am a Button" />

android:layout_width="228dp"
android:layout_height="fill_parent"
android:layout_gravity="left" >
<TextView
android:id="#+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello, I am a TextView" />
</LinearLayout>
</LinearLayout>
A RelativeLayout will accomplish what you want
<?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">
<LinearLayout
android:id="#+id/rightLayout"
android:layout_width="100dip"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:background="#003300"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="#+id/topLayout"
android:layout_toLeftOf="#id/rightLayout"
android:layout_width="fill_parent"
android:layout_height="100dip"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="#330033"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="#+id/bottomLayout"
android:layout_toLeftOf="#id/rightLayout"
android:layout_below="#id/topLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:background="#334433"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
The result as LinearLayouts and as Buttons/TextViews (since I wasn't sure which you wanted):
If you are using the LinearLayouts as a container to hold multiple views then leave it as I have it.
If you plan on having only one view in each of your "parts" change the LinearLayouts in my layout file to that type.
Ex. if you want Part 1 to be just a button change
<LinearLayout
android:id="#+id/topLayout"
to be
<Button
android:id="#+id/topLayout"
Nested views are bad so its good to avoid them if you can
you could :
Main linear layout with vertical alignment
add a new linear layout with horizontal alignment
add a new linear layout with horizontal or vertical alignment
So in the first layout ( the left part of main layout) you add a new linear layout with horizontal alignment and add the two elements you want.
In the second layout ( the right part of main layout) you add a new linear layout or directly the object you want to show

Here I am displaying the ListView data dynamically....but in my emulator it is displaying a TextView at the top and then the ListView with scroll...It is not expanding the list and instead it is scrolling with the content which is generated dynamically...Please tell me how to expand the entire ListView....

You have an error here
<ListView
android:layout_width="fill_parent"
android:id="#+id/listlist" //error here
android:layout_height="fill_parent">
</ListView>
the ListView is filled of the LinearLayout
so that you can't get the TextView.
instand of this
you can layout your view as follows:
<ListView
android:layout_width="match_parent"
android:id="#+id/listlist" //error here
android:layout_height="0"
android:layout_weight="1.0>
android:layout_weight="1.0" //this will make the list view filled with the rest of the screem
Further more
I suggest you use "match_parent" instand of "fill_parent"
this WAS CHANGED in the SDK level 8...
OK, now you use the RelativeLayout install of the LinearLayout
So you should add the relationship with your views in your layout.
You can layout as this:
<RelativeLayout
android:id="#+id/widgetlay"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/txt1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="" >
</TextView>
<ListView
android:id="#+id/listlist"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/txt1" />
android:layout_below="#id/txt"----Indicate the relationship with the layout
The RelativeLayout does not have the attr "orientation" and "layout_weight". So I don't suggest you to use this layout, It can't be fixed with the screen height in that way.
The good layout is:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/txtvw1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="status" >
</TextView>
<ListView
android:id="#+id/listlist"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.0" />
Further more, what do you want to layout your views?
This is a part of my work. List view will appear in the middle of your screen and what ever u need at the top, put it in place of header() and things that u need in bottom of the screen , put it in place of footer(). U can use relative layout instead of the linear layout
Hope this helps.

I don't know what is meaning of expanding meaning here, but listView in scroll view dont behave normally. To resolve this issue you need to implement list view outside of scrollview.
I don't quite understand what you mean, but if you want to have the textView scroll with the content of the listView, you need to add it as a header in your listView.
Moreover, it is not a good idea to put a listview in a scrollview, the listview being scrollable, it messes with the scrollview mechanism.
You can NEVER ever place a listview in the SCrollView.It wont behave properly.Instead of it try using LinearLayout TextView ListView < /Linearlayout>
