Android bitmap tileModeY="repeat" with gravity="fill_horizontal" creates ugly edge

I want to create vertically repeating background for whole app that is adjusted to width of phone.
My bitmap is:
resources/drawable/repeating_bitmap.xml
<?xml version="1.0" encoding="utf-8"?>
<bitmap
xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/app_bg_003_phone"
android:gravity="fill_horizontal"
android:tileModeY="repeat" />
My style is:
resources/values/style.xml
<style name="AppTheme" parent="BaseTheme">
<item name="android:windowBackground">#drawable/repeating_bitmap</item>
</style>
And my problem is here:
As you can see, instead of whole image only the edge is stretched, Weird.
How can i achieve horizontally stretched and vertically repeated background?
I have used proper flags on bitmap... (android:gravity="fill_horizontal" android:tileModeY="repeat")
If this could help this im attaching original image that im repeating (mdpi)
I want to use repeating bitmap to save up on memory. Also this is only jpeg pattern that is available for me at the moment.
Update
Now i know why only edge is streched: From documentation:
https://developer.android.com/reference/android/graphics/drawable/BitmapDrawable
"Gravity is ignored when the tile mode is enabled. Default value is "disabled"."
That means when i got tileModeY="repeat", then tileModeX by default as i enabled tile mode overall, must be tileModeX="clamp" which is:
"clamp Replicates the edge color."
Any ideas how i can use tileMode and gravity at the same time? I tried to insert this bitmap into another view where gravity would be "fill_horizontal". Sadly without success.

I found a pretty fancy way of achieving this:
Remove the tileMode attribute from the "bitmap"
Create a "layer-list" root tag in the XML
Add an "item" tag around the "bitmap" with top and height attributes (set the height to that of the image)
Copy&paste this "item" as many times as you think you need it to fill the display
Enter the proper top value for each of the "item" tags
Here is an example where the image for the background is 116 pixel high. Therefore each of the following tags has a top value increased by this height.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="0dp" android:height="116dp">
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="fill_horizontal" android:src="#drawable/background" />
</item>
<item android:top="116dp" android:height="116dp">
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="fill_horizontal" android:src="#drawable/background" />
</item>
<item android:top="232dp" android:height="116dp">
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="fill_horizontal" android:src="#drawable/background" />
</item>
<item android:top="348dp" android:height="116dp">
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="fill_horizontal" android:src="#drawable/background" />
</item>
<item android:top="464dp" android:height="116dp">
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="fill_horizontal" android:src="#drawable/background" />
</item>
<item android:top="580dp" android:height="116dp">
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="fill_horizontal" android:src="#drawable/background" />
</item>
</layer-list>

How to add padding to the logo in launch screen?

I would like to add padding or space to the logo on both the sides and the code is added here.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" android:gravity="fill">
<item android:drawable="#color/ns_theme"></item>
<item>
<bitmap android:gravity="center" android:src="#drawable/logo" />
</item>
</layer-list>

I had the same problem, I tried to add padding to the item but it didn't change anything.
<item
android:left="16dp"
android:right="16dp">
<bitmap android:gravity="center"
android:src="#drawable/splash"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"/>
</item>
The problem was gravity="center", with it the padding were not applied.
Try using android: gravity = "clip_horizontal"
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/splash_color" />
<item
android:left="16dp"
android:right="16dp">
<bitmap android:gravity="clip_horizontal"
android:src="#drawable/splash"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"/>
</item>
</layer-list>

Use
android:bottom=""
android:left=""
android:right=""
android:top=""
Try this
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="fill">
<item android:drawable="#color/ns_theme"></item>
<item
android:bottom="20dp"
android:left="20dp"
android:right="20dp"
android:top="20dp">
<bitmap
android:gravity="center"
android:src="#drawable/logo" />
</item>
</layer-list>

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/ns_theme" />
<item
android:drawable="#drawable/ic_logo"
android:left="#dimen/_16sdp"
android:right="#dimen/_16sdp" />
</layer-list>

The problem is probably that your logo is too big (The image file you are using has a pixel width that exceeds the pixel density of the device you are running it on).
Whether or not that is the case, it would probably be better to approach the problem considering the possibility that it could be run on ANY Android device with ANY screen size.
Considering that, there are several options better than simply adding padding in xml... For example, you could:
1) Wrap the image inside another view object that you can control the size and postion of as Bhavik Makwana suggested.
2) Just simply re-edit/resample your image to match the width of your target device and include the white space you desire in the image itself.
3) Design full splash screens that match the entire screen exactly (which combine foreground and background into one image), for example one with 1080 x 1920 resolution, and others for other screen sizes. That way you can control exactly how you want it to look, and the resolution will be 1-1 with no anti-aliasing or resampling.
4) Use this "9-patch" image approach to define an absolute width and height for your logo, but allow stretching of the white space around it to accommodate different screen sizes.
or, finally, the best way:
5) Use a constraint layout with guidelines in order to define the width of your logo in terms of percentage of parent width rather than absolute value.
Some other advice: Unless you are using technique #2 above, make sure you are using a logo.png file like this:
... NOT like this:
KaBOOYOW!
-Boober.

try this code:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/colorPrimary" />
<item>
<bitmap android:src="#drawable/logo"
android:gravity="center" />
</item>
</layer-list>

<layer-list
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:gravity="center"
android:layout_height="match_parent"
android:layout_width="match_parent">
<item
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp"
android:gravity="center"
android:background="#mipmap/logo" />
</layer-list>

Set SeekBar's progress color to transparent

Here is a picture of what I want to accomplish, where there is no progress color (transparent), with a solid grey background bar:
I tried
android:progressTint="#00000000"
But that sets the whole bar (progress bar AND the back bar) to transparent.
I also tried:
android:progressDrawable="#drawable/customseekbar"
where customseekbar.xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#android:id/background"
android:drawable="#drawable/seekbar_background" />
<item android:id="#android:id/progress">
<clip android:drawable="#drawable/seekbar_background" />
</item>
and seekbar_background.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid
android:color="#FF555555" />
</shape>
but then I get this fat and ugly:
What am I doing wrong here? Thanks

How to Style a Seekbar in Android
Here you go, you need to do the following
Step 1:
In drawable, put "progress_bg.png" (find attached)
Step 2:
In drawable, create "myprogessbar_style.xml", and insert the following
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background"
android:drawable="#drawable/progress_bg" />
<item
android:id="#android:id/secondaryProgress"
>
<scale
android:drawable="#drawable/progress_bg"
android:scaleWidth="100%"/>
</item>
<item
android:id="#android:id/progress"
android:drawable="#drawable/progress_bg"/>
</layer-list>
Step 3:
Your seekbar
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_margin="10dp"
android:indeterminate="false"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:progressDrawable="#drawable/myprogessbar_style"/>
Result
Attachment
P.S. Yes, it's not a transparency but the expected result

This seems to work:
<SeekBar
...
android:progressTint="#android:color/transparent"
... />

seekbar_background.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke android:height="1px" android:color="#FF555555" />
</shape>
1px line shape

android:maxHeight="3dp" add this to your layout xml where you have mentioned the seekbar. You can change the dp if you wish to decrease the height

That's much easier to solve. In your seekbar_background.xml:
Instead of:
android:color="FF555555"
Try:
android:color="#android:color/transparent"

If you want to do it programatically:
seekBar.progressTintList = ColorStateList.valueOf(Color.TRANSPARENT)

android:background="#android:color/transparent"
This set my SeekBar in Android Studio background to transparent. Pretty straight forward.

weird Looking seekbar in Android Tablets

I am working on an APP Which supports both phones and tablets.
Phones it is working fine but when i run the same in 7" tablet the seekbar looks weird ...
can anybody help me with this
This the custom xml i have used to show the seekbar
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#android:id/background"
android:drawable="#drawable/progress_unselected">
</item>
<item
android:id="#android:id/secondaryProgress"
android:drawable="#drawable/secondary_progress">
</item>
<item
android:id="#android:id/progress"
android:drawable="#drawable/progress_selected">
</item>
</layer-list>
My seekbar is inside a RelativeLayout with android:layout_alignParentBottom="true"
<SeekBar
android:id="#+id/SeekBarTestPlay"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/adView"
android:layout_alignParentBottom="true"
android:layout_marginLeft="5.0dip"
android:layout_marginRight="10.0dip"
android:max="99"
android:paddingBottom="10.0dip"
android:progressDrawable="#drawable/progressbar"
android:thumb="#drawable/progress_indicator"
android:thumbOffset="0.0dip" />

You need to make this background nine patch and make dither true. This gives perfect background without break.
<item android:id="#android:id/background">
<nine-patch xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/seek"
android:dither="true" />
</item>

Selector in Custom View With 9 Patch Image Background

I have problem with implementing selector in custom view. I have searched it for the last 1 hour but I could not find the solution. I have custom view with imageview, some textviews and nine patch background but the problem is when it's on pressed state, the color of selector doesn't cover the image view.
For the implementation, I'm using background selector for the layout and I just change the 9 patch image on pressed and un-pressed state, then disable default selector in listview.
Do you have any better solution? I see in google play, the blue selector covers all of the views and that is what I want.
For the xml,
<?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="#drawable/touch_selector"
android:orientation="horizontal"
android:padding="16dp" >
<ImageView />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView />
<TextView />
</LinearLayout>
</LinearLayout>
And for the touch selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/card_background_pressed" android:state_focused="true"/>
<item android:drawable="#drawable/card_background_pressed" android:state_pressed="true"/>
<item android:drawable="#drawable/card_background_white" android:state_focused="false" android:state_pressed="false"/>
</selector>
where card_background is 9 patch image.
EDIT :
This is the example from google play,

The accepted is not correct.
It's possible to use a nine-path in the selector, you just need to use the <nine-patch>. Something like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true">
<nine-patch
android:src="#drawable/marker"/>
</item>
<item>
<shape>
<solid android:color="#000000" />
</shape>
</item>
</selector>
