Seekbar using custom 9-patch images for progress and background - android

I'm trying to implement SeekBar with custom progress and backround.
Seekbar
<SeekBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:id="#+id/seekBar"
android:paddingLeft="2dp"
android:paddingRight="2dp"
android:thumbOffset="0dp"
android:maxHeight="6dp"
android:tag="seekbar"
android:thumb="#drawable/circle_seekbar_player_fragment" android:progressDrawable="#drawable/styled_progress_player_fragment"/>
styled_progress_player_fragment.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_backgroun">
</item>
<!--<item android:id="#android:id/secondaryProgress">
<scale
android:drawable="#drawable/rounded_corners_seekbar_transparent"
android:scaleWidth="100%" />
</item>-->
<item
android:id="#android:id/progress">
<scale
android:drawable="#drawable/seekbar_progres"
android:scaleWidth="100%"/>
</item>
</layer-list>
Background seekbar_backgroun.9.png
Progress image seekbar_progres.9.png
In 9patch window it is scaled as i want:
But in my app it's acting strange or maybe i'm not doing smthng right
Can you help me so my seekbar look fine
EDIT
Problem solved. The problem was that when i use ninepatch it uses resolurion in px not in dp, that's why it was scaling down
I fixed it by placing this ninepatch images to xxhdpi folder

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>

How to add number scale inside android seekbar?

I'm trying with the custom seekbar inside have number scale, But is not working. This seekbar must support all screen resolutions. how can i make like this. Please give your valuable idea.
My custom_seekbar.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/unselect"/>
<item
android:id="#android:id/secondaryProgress"
android:drawable="#drawable/select">
</item>
<item
android:id="#android:id/progress"
android:drawable="#drawable/select">
</item>
activity_main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/default_screen_bg"
android:orientation="vertical"
tools:context=".MainActivity" >
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:indeterminate="false"
android:max="10"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:progressDrawable="#drawable/custom_seekbar" />
</LinearLayout>
Unselesct.png
select.png
myresult screen like this
I'm expecting like this
There's number to solutions to the problem:
Use 9patch image for backgorund (which is basically should be used as background for seekbar). Like the following:
(name should be unselect_patch.9.png) and slightly modify custom_seekbar.xml to look like the following:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#android:id/background"
android:drawable="#drawable/unselect_patch"/>
<item android:id="#android:id/secondaryProgress">
<clip>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/select"
android:tileMode="disabled" />
</clip>
</item>
<item android:id="#android:id/progress">
<clip>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/select"
android:tileMode="disabled" />
</clip>
</item>
</layer-list>
Just provide exact size of the image in layout (e.g. layout_width="#dimen/select_image_width");
To support all resolutions - provide images for different resolutions, as described in Supporting Multiple Screens. The same images will not work fine for all resolutions and here's better just follow best practices described in detail at the link above.

Trouble with custom seekBar android

i have a trouble with custom seekBar .I used http://android-holo-colors.com/ to give images of seekBar .The problem is a vague beginning of seekBar . How can i solve this problem?!
ScreenShot:
this code (i check , images are the same as the default except for colors.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background"
android:drawable="#drawable/scrubber_track_red" />
<item android:id="#android:id/secondaryProgress">
<scale android:scaleWidth="100%"
android:drawable="#drawable/scrubber_secondary_red" />
</item>
<item android:id="#android:id/progress">
<scale android:scaleWidth="100%"
android:drawable="#drawable/scrubber_primary_red" />
</item>
</layer-list>
and SeekBar
<SeekBar
android:id="#+id/seekTrack"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:progressDrawable="#drawable/scrubber_progress_red"
android:thumb="#drawable/scrubber_control_red"
android:indeterminate="false"
android:layout_weight="1"
style="?android:attr/progressBarStyleHorizontal"/>
Images i got from aforementioned service (android holo colors)
Check your drawables, there's probably a gradient in there somewhere as opposed to a solid color. I'd guess that the problem is in #drawable/scrubber_progress_red. Replace it temporarily with something like #android:color/holo_green_light. If the gradient goes away, we'll know that the scrubber_progress_red drawable is the problem.
Also, what is the name of the file that the layer-list is in?
