Hiding the main layout of Custom Dialog - android

I have made layout for custom dialog, it has inside two imageview. I want to show both Imageview when dialog appear. and i want to hide the main layout of my xml file I have used "#00000000" as background:color, but it is not working.
Is there any way to do the same?
Thanks.
Here is my layout. I have taken screen shot please have a look i want to hide the border which are showing in image.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent"
android:orientation="vertical" android:background="#00000000">
<LinearLayout android:id="#+id/linearLayout1"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
<ImageView android:id="#+id/img_closeimage" android:src="#drawable/product_zoom_close"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:clickable="true"></ImageView>
</LinearLayout>
<LinearLayout android:id="#+id/linearLayout2"
android:layout_marginLeft="25dip" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_marginTop="-5dip" android:layout_marginBottom="20dip" android:layout_marginRight="20dip">
<ImageView android:id="#+id/img_ProductZoom" android:src="#drawable/index"
android:layout_width="wrap_content" android:layout_height="wrap_content"
></ImageView>
</LinearLayout>
</LinearLayout>

Adinias comment is correct, your layout has quite some redundancy. You also say that you only want to show an imageview, but your layout contains two imageviews. If you only want to show one imageview, then your layout should look like this:
<?xml version="1.0" encoding="utf-8"?>
<ImageView android:id="#+id/img_ProductZoom" android:src="#drawable/index"
android:layout_width="wrap_content" android:layout_height="wrap_content"
/>
If you want to show two ImageViews, use this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent"
android:orientation="vertical" android:background="#00000000">
<ImageView android:id="#+id/img_closeimage" android:src="#drawable/product_zoom_close"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:clickable="true"/>
<ImageView android:id="#+id/img_ProductZoom" android:src="#drawable/index"
android:layout_width="wrap_content" android:layout_height="wrap_content"
/>
</LinearLayout>
Your current layout looks the way it does because you have specified the layout to take as much space as possible with android:layout_height="fill_parent" and android:layout_width="fill_parent". Try to use wrap_content as height and width instead.

Output Design of a layout is not exact what is set while developing the Layout

I am trying to design a layout ( basically a splash screen ) which shows the App logo in almost middle of the screen and the company tagline under the logo on the start of the App. While working in Android Studio the design of layout looks like this. I positioned it 200dp downwards from the top.
As you can see, logo is right in the middle of the screen.
But when i run the app on my emulator the screen appears like this.The logo is not at the exact position where i wanted it.
I want my logo at the same relative position, no matter how big the screen size is.
Assume if logo is positioned at 200dp at 1000dp long screen. i want it at 400dp position on a 2000dp screen size.

Here is the XML code :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#f84343"
android:weightSum="1">
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:id="#+id/AppIcon"
android:src="#drawable/unnamed"
android:layout_marginTop="200dp"
android:layout_centerHorizontal="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/simpler_better_faster"
android:id="#+id/textView"
android:layout_gravity="center_horizontal"
android:layout_below="#+id/AppIcon"
android:layout_centerInParent="true"
android:layout_marginTop="50dp"
android:textColor="#ffffff"
android:textSize="20dp" />
</RelativeLayout>
You don't need to use a <RelativeLayout> to achieve that. Below is the code using a <LinearLayout>. The key here is android:gravity="center" in the <LinearLayout> element:
<?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="#f84343"
android:orientation="vertical"
android:gravity="center">
<ImageView
android:id="#+id/AppIcon"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/unnamed"/>
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:text="#string/simpler_better_faster"
android:textColor="#ffffff"
android:textSize="20dp"/>
</LinearLayout>
[EDIT]
OP - But if i go on using more widgets to the screen i might need to
position them relative to each other. how to overcome that with
Relative layout
Well, technically you can still add more widgets in their required order. But, if you really want to use a <RelativeLayout>, you can use something like:
<?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:background="#f84343"
android:gravity="center_vertical">
<ImageView
android:id="#+id/AppIcon"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_centerHorizontal="true"
android:src="#drawable/unnamed"/>
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:layout_below="#id/AppIcon"
android:text="#string/simpler_better_faster"
android:textColor="#ffffff"
android:layout_centerHorizontal="true"
android:textSize="20dp"/>
</RelativeLayout>
It looks like you've mixed up some RelativeLayout/LinearLayout attributes.
If you want to use RelativeLayout remove and modify some attributes.
Something like this instead
<?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:background="#f84343">
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:id="#+id/AppIcon"
android:src="#drawable/unnamed"
android:layout_centerInParent="true"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/simpler_better_faster"
android:layout_below="#id/AppIcon"
android:id="#+id/textView"
android:layout_marginTop="50dp"
android:textColor="#ffffff"
android:textSize="20dp" />
</RelativeLayout>
Simplify it all down into a TextView if you ask me
<?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:background="#f84343" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/simpler_better_faster"
android:drawableTop="#drawable/arrow_right_fill_dark" />
</RelativeLayout>
This gets rid of the ImageView all together, the change being the drawableTop attribute that provides a drawable, centered above the text.

make child of tabwidget bigger than tabwidget

I have 5 buttons on tab widget, 2 from left and 2 from right are the same size as background of tabwidget. The central button needs to be twice higher than tabwidget.
if I put all buttons into tabhost, tabhost's size rises equels to the biggest button (central button).
How to prevent it?
I want to make something like this. The background height of tabbar needs to be equel to red square's height.
Yes, you can do this by following Xml code -
center_tab_indicator.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="0dip"
android:layout_height="65dip"
android:layout_weight="1"
android:orientation="vertical"
android:background="#drawable/center_tab_indicator"
android:padding="5dp">
<ImageView android:id="#+id/icon"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/camera"
android:scaleType="center"/>
</RelativeLayout>
tab_indicator.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="0dip"
android:layout_height="55dip"
android:layout_weight="1"
android:orientation="vertical"
android:layout_marginTop="10sp"
android:background="#drawable/tab_indicator"
android:padding="5dp">
<ImageView android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:src="#drawable/icon" />
<TextView android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
style="?android:attr/tabWidgetStyle"
/>
</RelativeLayout>
By use of above two XML You can get your desired output. For more, have a look at here You will get an out put like below -
Have a look at that. There will be sample project also available. Hope it helps you.

not whole list item is clickable in the ListView

Yes I read this question. No it didn't help.
The problem is that only the highlighted area of my ListView cell is clickable. It is the area that is filled with text. Take a look on the picture:
So when you click on the circled area - it wouldn't respond.
Any ideas on how to make it work properly???
Edit: my list layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp">
<ImageView
android:id="#+id/shoulderLogo"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="20dp"
android:layout_marginTop="5dp">
</ImageView>
<TextView
android:id="#+id/shoulderLabel"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</TextView>
</LinearLayout>
I'm pretty sure this is because your list layout LinearLayout has a layout_width of wrap_content. This will cause your row to only be as wide as the views contained within. If you set it instead to fill_parent or match_parent it will extend to fill the width of your list.
Try changing to 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="wrap_content"
android:padding="5dp">
<ImageView
android:id="#+id/shoulderLogo"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="20dp"
android:layout_marginTop="5dp">
</ImageView>
<TextView
android:id="#+id/shoulderLabel"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</TextView>

creating a list using android xml and java

I got a list from the web (link is here )
where it uses two xml layouts to create a list, the first xml is just the background where the second xml is going to be displayed as buttons in a list.
what I am trying to do is have that same list but add a tittle or a picture title at the top, i've been playing around with the list but i cant get it to work, the only way i can think to make this happen is somehow moving the position in which the second xml is displayed and have the top part to add whatever i like.
Thank you for the help and ideas to make this work!
[EDIT] code snippet...
First XML layout
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="schemas.android.com/apk/res/android";
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_weight="1"
android:scrollbars="none"
android:divider="#000000"
android:scrollingCache="true" android:layout_height="wrap_content"/>
Second XML layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#AA010101"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ListView android:id="#+id/list"
android:layout_width="1px"
android:layout_height="1px"
android:layout_weight="1">
</ListView>
<RelativeLayout xmlns:android="schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:paddingLeft="10dp"
android:paddingTop="5dp"
android:paddingBottom="5dp"
android:layout_height="fill_parent">
<ImageView android:id="#+id/img"
android:layout_width="80dp"
android:layout_height="70dp"
android:layout_alignParentLeft="true"
android:scaleType="fitXY" />
<TextView android:layout_width="wrap_content"
android:id="#+id/title"
android:layout_height="wrap_content"
android:paddingTop="18dp"
android:layout_toRightOf="#+id/img"
android:textStyle="bold"
android:textColor="#ffffff"
android:layout_marginRight="50dp"
android:paddingLeft="10dp"
android:textSize="16sp" />
</RelativeLayout>
</LinearLayout>
You have to edit the XML file containing the <ListView>, by adding whatever you want before (most probably a TextView with a Compound Drawable). So that what you called the "background" looks more like this:
Main layout should host a <TextView> (+eventuall a Compound Image) + a <ListView>.
Secondary layout should host the content of each of your list item. If you have a <ListView> in each XML layout, it means you will have a list of lists... I don't know much about your list and app, and do not know what information you would like to display in each list item (e.g. ContactName, CalendarDate, Cities... whatever). But there are very few chances that you need a ListView in both of them.
mainListLayout.xml
<?xml version=”1.0″ encoding=”utf-8″?>
<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android”
android:orientation=”vertical”
android:layout_width=”fill_parent”
android:layout_height=”fill_parent”>
<TextView
android:id="#+id/Text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="text to replace image"
android:drawableLeft="#drawable/reference"
android:text="Title of the list"/>
<ListView
android:id=”#android:id/list”
android:layout_width=”fill_parent”
android:layout_height=”wrap_content” />
</LinearLayout>
The Drawable can obviously be on the Right, Top or Bottom, and not only on the Left. You might also like to have a look at android:drawablePadding="#dimen/xxx to add some extra space between text/title and the image. Drawable has to be one of your ic_* png files from res/drawable (eventually -hdpi, -mdpi and so on)
itemLayout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relativelayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:contentDescription="#string/ItemIcon"
android:layout_width="000"
android:layout_height="000"
android:src="#drawable/ic_icone"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"/>
<TextView
android:id="#+id/ItemDescription"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:textColor="#000000"
android:text="ItemDescription" />
</RelativeLayout>

layout_height always wrapping content

it's just a simple question:
I have a layout file which is presented as an item inside of a ListView. I set the height of the RelativeLayout to 100dp, but it does not work, it's always wrapping the content, no matter which layout I use. What can I do to set a fixed value to the layout height without having it wrapping?
Thanks for the help.
<?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="100dp"> <!-- this attribute seems to be ignored -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true">
<ProgressBar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="#dimen/progressbar_small"
android:layout_height="#dimen/progressbar_small"
android:layout_gravity="center_vertical" />
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:text="#string/loading"
android:layout_gravity="center_vertical"
style="#style/ListItemSubtext" />
</LinearLayout>
</RelativeLayout>
Do like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="100dip">
I think in a list view all items are of the same height. In your case you could add the progress bar in the list footer view. Add a dummy height adjuster right before or after ListItemSubtext. Try using TableLayout instead of Relative and Linear Layout.
A dummy adjuster is like this.
<View android:layout_width="wrap_content" android:layout_height="100dip"/>
Please note you do not need xmlns in every element.
Try just using 100px. Works for me.
i do below changes in your xml..
<?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="100dp"> <!-- this attribute taking a fixed value as u said -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_centerHorizontal="true"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">
<ProgressBar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_gravity="center_vertical"
android:layout_width="20dip"
android:layout_height="20dip"/>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:text="#string/loading"
android:layout_gravity="center_vertical"
style="#style/ListItemSubtext" />
</LinearLayout>
If this doesn't work for you, say what exactly you want to do.
