I've added an image to my xml file. This is the code that I am using:
<?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="wrap_content"
android:src="#drawable/topbar_logo2x"
android:scaleType="fitStart" />
<TabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<View
android:layout_width="fill_parent"
android:layout_height="0.5dip"
android:background="#000" />
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="0dip"
android:layout_marginRight="0dip" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
</TabHost>
</LinearLayout>
I want my TabHost to be exactly on top of my image. When I checked up some answers in StackOverflow, I got an answer that stated to use
android:scaleType="fitStart"
I want to use both android:scaleType="fitStart" and android:scaleType="fitEnd" on the same ImageView and that is not possible as Sndroid will allow only one declaration of scaleType. How will I be able to attain the same with change in code ? Is there some other command that will help me?
Seems to me the larger black line must come from the image (topbar_logo2x) or the way it is scaled into the ImageView. Try using scaleType="fitXY" to see if the above black line vanishes. If not, then post the image for us to look.
Seems to me the View below LinearLayout causes the smaller black line. Remove it.

add attribute android:scaleType="fitXY" to imageview
I add the following code to main.xml to set an image as a background image for my app:
android:background="#drawable/bg"
So main.xml looks like this:

And of course the image bg.png is in drawable.
The problem is that the background image is shown only in the emulator but not in my actual device (HTC Desire).
What have I done wrong? What do I need to do to solve this problem?
Can you guys there help? Thank you very much.
I found the problem . Just remove fill_parent from the main Linear Layout Gravity. No need to set background in the Listview as you do right now. Just Change as i suggest it solve your problem.
android:gravity="bottom|fill_vertical"
try this in place of that
<LinearLayout
xmlns:android= "http://schemas.android.com/apk/res/android"
android:id="#+id/linearlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/image"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/bg" />
</Linearlayout>
I got a similar bug my background drawable was shown in the graphical editor of eclipse but not on the devices I used for debugging.
-> For me it helped to clean the image (I just opened it in paint and saved it) after that i
overwrote the old image with the new one and copied it into the drawable folders.
Some lolipop devices wouldn't show with higher resolution images. You could also manually resize the bitmap programmatically if you generate the backgrounds randomly or use a set of images to load them into the background
It's pritty hard to explain what I like to have. In my Layout I got a horizontal LinearLayout.
Now I'd like to know if its possible to create a thin border around it. For example take a look at the ListView, there it also haves those thin borders, I exactly like to have that in my LinearLayout.
I hope you understood me, if you need more information write a comment below.
Thx in advance

Additional Information:
If you take a look at the screenshot you see there those redlines, exactly there i'd like to have those thin borders, like in my Listview up there! Under the screenshot you also find the code of the layout.

What I understood from your question is that it actually might require setting the background of your layout.
This can be done by creating your own border.xml. Here is somewhat similar question answering what you need.
if all you need is to create a border then take a parentView , set background by border color ,set pading by border thikness , then add child inside with foreground as its background .
I've searched for an answer for this all over but the solutions offered did not solve my problem.
I have a layout where I display some views (a few buttons and a background). To this i've added a custom control i've made extending linear layout. This control is displayed above the layout quite nicely.
What I wish to do is add an additional ImageView which is larger than this control but it will be in front of it.
edited: Sorry, I hope this will clear things up.
I have one large layout (Relative) for my activity, I would like to stack on this layout two additional views\layout so the final version will be the picture attached:
This is my layout - which stacks the imageview right on the menubar, and not over the others. Trying to put the FrameLayout elsewhere still didn't give me the wanted result.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background">
<RelativeLayout android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="450dip">
<com.myproject.controls.SearchControl
android:id="#+id/scSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<ExpandableListView android:id="#+id/lstItems"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/scSearch"
android:layout_marginLeft="26dip"

</RelativeLayout>
<FrameLayout android:layout_width="fill_parent"
android:layout_height="fill_parent">

Not sure it this will work or not cause I'm typing this up at work. But moral of the story here is get used to using RelativeLayout. You have much more control over your layout.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background">
<com.myproject.controls.MenubarMain
android:id="#+id/mbMenuBarMain"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
</com.myproject.controls.MenubarMain>
<com.myproject.controls.SearchControl
android:id="#+id/scSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true">
</com.myproject.controls.SearchControl>
<ExpandableListView android:id="#+id/lstItems"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/scSearch"
android:layout_above="#id/mbMenuBarMain"
android:layout_paddingLeft="26dp"/>
<ImageView android:src="#drawable/myicon"
android:layout_width="200dp"
android:layout_height="200dp"
android:layout_alignBottom="#id/mbMenuBarMain"
android:layout_alignRight="#id/mbMenuBarMain"/>
</RelativeLayout>
I have a screen that uses tabs in my android application. There is a line (like a border) that shows between the tabwidget and the framelayout. I want to get rid of that line, but cant seem to find what it is. I have determined that it is part of the FrameLayout by setting its visibilty to gone. Please refer to the code below:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#fb8c10"
>
<ImageView
android:id="#+id/img_confirm_header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="#drawable/confirm_header"
/>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="0dip"
android:background="#fb8c10"
android:tabStripEnabled="false"
/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/tab_bg"
/>
</LinearLayout>
</TabHost>
This is a link of the current layout and what I'm trying to do
http://img441.imageshack.us/g/screenshot20110116at513.png/
The orange layout is my app, and the gray is what I'm trying to do.
Notice how in the gray screenshot the tab flows into the frame.
Apologies for the links, I can't post images yet :p
Thanks!
I managed to solve this by manipulating the z-index using relative layout. I was able to position the tabs slightly over the frame layout. Refer to code below:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#fb8c10"
>
<ImageView
android:id="#+id/img_confirm_header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="#drawable/tab_header"
/>
<RelativeLayout
android:id="#+id/widget77"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/transparent"
>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/transparent"
android:layout_marginTop="33dip"
/>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#fb8c10"
android:tabStripEnabled="true"
android:layout_above="#android:id/tabcontent"
android:layout_marginBottom="40dip"
/>
</RelativeLayout>
</LinearLayout>
</TabHost>
Just now I came across this issue. However, I also tried to remove the top border of FrameLayout. I did it. but I don't think it is a way to remove the top border. anyway FYI,
Just place an TextView with background white on Border and use AbsoluteLayout.
Eg:
<AbsoluteLayout>
<TabHost
android:layout_x="0dip"
android:layout_y="5dip" ...>
<AbsoluteLayout android:padding="5dip" android:background="#ffffff">
<TabWidget/>
<FrameLayout ....
android:layout_x="0dip" android:layout_y="65dip" />
</AbsoluteLayout>
</TabHost>
<TextView
android:layout_width="fill_parent" android:layout_height="25dip"
android:layout_x="0dip" android:layout_y="65dip"
android:background="#ffffff"/>
</AbsoluteLayout>
