Custom seekbar (thumb size, color and background)

Question

I would like to have this seekbar in my Android project :

This is my seekbar :

<SeekBar
        android:id="@+id/seekBar_luminosite"
        android:layout_width="@dimen/seekbar_width"
        android:layout_height="@dimen/seekbar_height"
        android:minHeight="15dp"
        android:minWidth="15dp"
        android:maxHeight="15dp"
        android:maxWidth="15dp"
        android:progress="@integer/luminosite_defaut"
        android:progressDrawable="@drawable/custom_seekbar"
        android:thumb="@drawable/custom_thumb" />

This is my custom_thumb.xml :

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval" >

    <gradient
        android:angle="270"
        android:endColor="@color/colorDekraOrange"
        android:startColor="@color/colorDekraOrange" />

    <size
        android:height="35dp"
        android:width="35dp" />

</shape>

This is my custom_seekbar.xml :

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@android:id/background"
        android:drawable="@drawable/seekbar"/>
    <item android:id="@android:id/progress">
        <clip android:drawable="@color/colorDekraYellow" />
    </item>

</layer-list>

This is my seekbar.png (background) :

And this is the result :

No shadow and no rounded borders in the bar...

I really not understand how I can do.

Answer 1

• First at all, use android:splitTrack="false" for the transparency problem of your thumb.

• For the seekbar.png, you have to use a 9 patch. It would be good for the rounded border and the shadow of your image.

Answer 2

All done in XML (no .png images). The clever bit is border_shadow.xml.

All about the vectors these days...

Screenshot:

This is your SeekBar (res/layout/???.xml):

SeekBar

<SeekBar
    android:id="@+id/seekBar_luminosite"
    android:layout_width="300dp"
    android:layout_height="wrap_content"        
    android:progress="@integer/luminosite_defaut"
    android:progressDrawable="@drawable/seekbar_style"
    android:thumb="@drawable/custom_thumb"/>

Let's make it stylish (so you can easily customize it later):

style

res/drawable/seekbar_style.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/border_shadow" >
    </item>

    <item 
        android:id="@android:id/progress" > 
        <clip 
            android:drawable="@drawable/seekbar_progress" />
    </item>
</layer-list>

thumb

res/drawable/custom_thumb.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/colorDekraOrange"/>
            <size
                android:width="35dp"
                android:height="35dp"/>
        </shape>
    </item>   
</layer-list>

progress

res/drawable/seekbar_progress.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list 
    xmlns:android="http://schemas.android.com/apk/res/android" >
    <item 
        android:id="@+id/progressshape" >
        <clip>
            <shape 
                android:shape="rectangle" >
                <size android:height="5dp"/>
                <corners 
                    android:radius="5dp" />
                <solid android:color="@color/colorDekraYellow"/>        
            </shape>
        </clip>
    </item>
</layer-list>

shadow

res/drawable/border_shadow.xml:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">       
    <item>      
        <shape> 
            <corners 
                android:radius="5dp" />
            <gradient
                android:angle="270"
                android:startColor="#33000000"
                android:centerColor="#11000000"
                android:endColor="#11000000"
                android:centerY="0.2"
                android:type="linear"
            />          
        </shape> 
    </item>
</layer-list>

Answer 3

No shadow and no rounded borders in the bar

You are using an image so the easiest solution is row your boat with the flow,

You cannot give heights manually,yes you can but make sure it gets enough space to show your full image view there

• easiest way is use android:layout_height="wrap_content" for SeekBar
• To get more clear rounded borders you can easily use the same image that you have used with another color.

I am no good with Photoshop but I managed to edit a background one for a test

_{seekbar_brown_to_show_progress.png}

<SeekBar
    android:splitTrack="false"   // for unwanted white space in thumb
    android:id="@+id/seekBar_luminosite"
    android:layout_width="250dp"   // use your own size
    android:layout_height="wrap_content"
    android:minHeight="10dp"
    android:minWidth="15dp"
    android:maxHeight="15dp"
    android:maxWidth="15dp"
    android:progress="50"
    android:progressDrawable="@drawable/custom_seekbar_progress"
    android:thumb="@drawable/custom_thumb" />

custom_seekbar_progress.xml

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@android:id/background"
        android:drawable="@drawable/seekbar" />
    <item android:id="@android:id/progress">
        <clip android:drawable="@drawable/seekbar_brown_to_show_progress" />
    </item>
</layer-list>

custom_thumb.xml is same as yours

Finally android:splitTrack="false" will remove the unwanted white space in your thumb

Let's have a look at the output :

Answer 4

At first courtesy goes to @Charuka .

DO

You can use android:progressDrawable="@drawable/seekbar" instead of android:background="@drawable/seekbar" .

progressDrawable used for the progress mode.

You should try with

android:minHeight

Defines the minimum height of the view. It is not guaranteed the view will be able to achieve this minimum height (for example, if its parent layout constrains it with less available height).

android:minWidth

Defines the minimum width of the view. It is not guaranteed the view will be able to achieve this minimum width (for example, if its parent layout constrains it with less available width)

    android:minHeight="25p"
    android:maxHeight="25dp" 

FYI:

Using android:minHeight and android:maxHeight is not good solutions .Need to rectify your Custom Seekbar (From Class Level) .

Answer 5

Android custom SeekBar - custom track or progress, shape, size, background and thumb and for other seekbar customization see http://www.zoftino.com/android-seekbar-and-custom-seekbar-examples

Custom Track drawable

<?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:gravity="center_vertical|fill_horizontal">
        <shape android:shape="rectangle"
            android:tint="#ffd600">
            <corners android:radius="8dp"/>
            <size android:height="30dp" />
            <solid android:color="#ffd600" />
        </shape>
    </item>
    <item android:id="@android:id/progress"
        android:gravity="center_vertical|fill_horizontal">
        <scale android:scaleWidth="100%">
            <selector>
                <item android:state_enabled="false"
                    android:drawable="@android:color/transparent" />
                <item>
                    <shape android:shape="rectangle"
                        android:tint="#f50057">
                        <corners android:radius="8dp"/>
                        <size android:height="30dp" />
                        <solid android:color="#f50057" />
                    </shape>
                </item>
            </selector>
        </scale>
    </item>
</layer-list>

Custom thumb drawable

?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    android:thickness="4dp"
    android:useLevel="false"
    android:tint="#ad1457">
    <solid
        android:color="#ad1457" />
    <size
        android:width="32dp"
        android:height="32dp" />
</shape>

Output

Answer 6

Use tints ;)

<SeekBar
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="15dp"
        android:minWidth="15dp"
        android:maxHeight="15dp"
        android:maxWidth="15dp"
        android:progress="20"
        android:thumbTint="@color/colorPrimaryDark"
        android:progressTint="@color/colorPrimary"/>

use the color you need in thumbTint and progressTint. It is much faster! :)

Edit ofc you can use in combination with android:progressDrawable="@drawable/seekbar"

Answer 7

android:minHeight android:maxHeight is important for that.

<SeekBar
    android:id="@+id/pb"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:maxHeight="2dp"
    android:minHeight="2dp"
    android:progressDrawable="@drawable/seekbar_bg"
    android:thumb="@drawable/seekbar_thumb"
    android:max="100"
    android:progress="50"/>

seekbar_bg.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">
        <shape>
            <corners android:radius="3dp" />
            <solid android:color="#ECF0F1" />
        </shape>
    </item>
    <item android:id="@android:id/secondaryProgress">
        <clip>
            <shape>
                <corners android:radius="3dp" />
                <solid android:color="#C6CACE" />
            </shape>
        </clip>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <corners android:radius="3dp" />
                <solid android:color="#16BC5C" />
            </shape>
        </clip>
    </item>
</layer-list>

seekbar_thumb.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#16BC5C" />
    <stroke
        android:width="1dp"
        android:color="#16BC5C" />
    <size
        android:height="20dp"
        android:width="20dp" />
</shape>

Answer 8

You can try progress bar instead of seek bar

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="fill_parent"
    android:layout_height="50dp"
    android:layout_marginBottom="35dp"
    />
