How To Change Seek bar Color in Android? [duplicate]

Question

I have two questions:

1) how do I change the color of the seek bar (path) from yellow (the default color) to white. What I mean to say is, while I slide the thumb , it turns the line traversed from grey to yellow. I want track/line to either remain grey or white..Basically I want just the thumb to move with no color change in the seek bar.

2) How to change the thumb of seekbar from rectangle to circle/sphere/round shape.

any pointers will be appreciated.

Answer 1

I want to complete the answer from above for the people who are new to the system,

the missing xmls ( background_fill , progress_fill and progress could look like that for a gradient red

progress.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/background_fill" />

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

background_fill.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient 
        android:startColor="#FF555555" 
        android:centerColor="#FF555555"
        android:endColor="#FF555555" 
        android:angle="90" />

    <corners android:radius="5px" />

    <stroke 
        android:width="2dp" 
        android:color="#50999999" />

    <stroke 
        android:width="1dp" 
        android:color="#70555555" />
</shape>

progress_fill.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient 
        android:startColor="#FF470000" 
        android:centerColor="#FFB80000"
        android:endColor="#FFFF4400" 
        android:angle="180" />

    <corners android:radius="5px" />

    <stroke 
            android:width="2dp" 
            android:color="#50999999" />

    <stroke 
            android:width="1dp" 
            android:color="#70555555" />
</shape>

i did not complete the implementing for android:thumb, so the thumb will be still the original one

Therefore we just have to delete this line again from our layout xml where we define the seekbar

android:thumb="@drawable/thumb"

Good luck!!!

Answer 2

You should set SeekBar XML properties:

<SeekBar 
            ....
    android:progressDrawable="@drawable/progress"
    android:thumb="@drawable/thumb"
            ....
/>

Where progress is something like this:

<?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/background_fill" />

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

and thumb is

<?xml version="1.0" encoding="utf-8"?>    
<selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:drawable="@drawable/thumb_fill" />
</selector>

Answer 3

Since SeekBar uses colorAccent by default, you can create a new style with your custom color as colorAccent then use theme attribute to apply it to the SeekBar.

<SeekBar>
    .
    .
    android:theme="@style/MySeekBarTheme"
    .
</SeekBar>

in the @style:

 <style name="MySeekBarTheme" parent="Widget.AppCompat.SeekBar" >
        <item name="colorAccent">#ffff00</item>
 </style>

Answer 4

seekBar.getProgressDrawable().setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);
seekBar.getThumb().setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);
