Android - styling seek bar

问题

I wanted to style a seek bar which looks like the one in the image below.

By using default seekbar I will get something like this:

So what I need is to only change the color. I need no extra styles. Is there any straight forward approach to do this or should I build my custom drawable.?

I tried building custom one, but I could not get the exact one as shown above. After using custom drawable, what I get is as shown below:

If I need to build the custom one, then please suggest how to reduce the width of the progress line and also the shape.

my custom implementation:

background_fill.xml:

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<shape xmlns:android=\"http://schemas.android.com/apk/res/android\" >

    <gradient
        android:angle=\"90\"
        android:centerColor=\"#FF555555\"
        android:endColor=\"#FF555555\"
        android:startColor=\"#FF555555\" />

    <corners android:radius=\"1dp\" />

    <stroke
        android:width=\"1dp\"
        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:angle=\"90\"
        android:centerColor=\"#FFB80000\"
        android:endColor=\"#FFFF4400\"
        android:startColor=\"#FF470000\" />

    <corners android:radius=\"1dp\" />

    <stroke
        android:width=\"1dp\"
        android:color=\"#50999999\" />
    <stroke
        android:width=\"1dp\"
        android:color=\"#70555555\" />

</shape>

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>

thumb.xml

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<shape xmlns:android=\"http://schemas.android.com/apk/res/android\"
    android:shape=\"oval\" >

    <gradient
        android:angle=\"270\"
        android:endColor=\"#E5492A\"
        android:startColor=\"#E5492A\" />

    <size
        android:height=\"20dp\"
        android:width=\"20dp\" />

</shape>

seekbar:

<SeekBar
        android:id=\"@+id/seekBarDistance\"
        android:layout_width=\"match_parent\"
        android:layout_height=\"wrap_content\"
        android:layout_alignParentLeft=\"true\"
        android:layout_alignParentTop=\"true\"
        android:layout_marginTop=\"88dp\"
        android:progressDrawable=\"@drawable/progress\"
        android:thumb=\"@drawable/thumb\" >
    </SeekBar>

回答1:

I would extract drawables and xml from Android source code and change its color to red. Here is example how I completed this for mdpi drawables:

Custom red_scrubber_control.xml (add to res/drawable):

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

    <item android:drawable="@drawable/red_scrubber_control_disabled_holo" android:state_enabled="false"/>
    <item android:drawable="@drawable/red_scrubber_control_pressed_holo" android:state_pressed="true"/>
    <item android:drawable="@drawable/red_scrubber_control_focused_holo" android:state_selected="true"/>
    <item android:drawable="@drawable/red_scrubber_control_normal_holo"/>
</selector>

Custom: red_scrubber_progress.xml

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

    <item
        android:id="@android:id/background"
        android:drawable="@drawable/red_scrubber_track_holo_light"/>
    <item android:id="@android:id/secondaryProgress">
        <scale
            android:drawable="@drawable/red_scrubber_secondary_holo"
            android:scaleWidth="100%" />
    </item>
    <item android:id="@android:id/progress">
        <scale
            android:drawable="@drawable/red_scrubber_primary_holo"
            android:scaleWidth="100%" />
    </item>

</layer-list>

Then copy required drawables from Android source code, I took from this link

It is good to copy these drawables for each hdpi, mdpi, xhdpi. For example I use only mdpi:

Then using Photoshop change color from blue to red:

red_scrubber_control_disabled_holo.png:

red_scrubber_control_focused_holo.png:

red_scrubber_control_normal_holo.png:

red_scrubber_control_pressed_holo.png:

red_scrubber_primary_holo.9.png:

red_scrubber_secondary_holo.9.png:

red_scrubber_track_holo_light.9.png:

Add SeekBar to layout:

<SeekBar
    android:id="@+id/seekBar1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:progressDrawable="@drawable/red_scrubber_progress"
    android:thumb="@drawable/red_scrubber_control" />

Result:

回答2:

My answer is inspired from Andras Balázs Lajtha answer it allow to work without xml file

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

回答3:

If you want exactly the same bar but in red, you can add a PorterDuff color filter programatically. You can get each drawable that you want to colorize through the methods of the ProgressBar base class. Then set a color filter for it.

mySeekBar.getProgressDrawable().setColorFilter(new PorterDuffColorFilter(srcColor, PorterDuff.Mode.MULTIPLY));

If the wanted color adjustment can't be made through a Porter Duff filter, you can specify your own color filter.

Just replace color atributtes with your color

background.xml

    <stroke android:width="1dp" android:color="#2EA5DE"/>
    <corners android:radius="1dp" />

    <solid android:color="#2EA5DE" />
    <corners android:radius="1dp" />

</shape>

回答6:

Google have made this easier in SDK 21. Now we have attributes for specifying the thumb tint colors:

android:thumbTint
android:thumbTintMode
android:progressTint

回答7:

As mention one above (@andrew) , creating custom SeekBar is super Easy with this site - http://android-holo-colors.com/

Just enable SeekBar there, choose color, and receive all resources and copy to project. Then apply them in xml, for example:

  android:thumb="@drawable/apptheme_scrubber_control_selector_holo_light"
  android:progressDrawable="@drawable/apptheme_scrubber_progress_horizontal_holo_light"

回答8:

Just set

android:maxHeight="3dp"
android:minHeight="3dp"

That's all

回答9:

<SeekBar
android:id="@+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:progressTint="@color/red"
android:thumbTint="@color/red" />

works Like same the answer selected. no need to make any drawable file or else.(IN 5.0 only) Regards

回答10:

All those answers are deprecated.

In 2019 it's easier to style your seekbar to your preferred color by changing your ProgressBar to this

<SeekBar
            android:id="@+id/seekBar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:progressTint="#36970f"
            android:thumbTint="#36970f"
            />

Styling your seekbar color programmatically try the following code

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

回答12:

By default, android will match the progress color of your slider to

`<item name="colorAccent">`

value in your styles.xml. Then, to set a custom slider thumb image, just use this code in your SeekBar xml layout's block:

android:thumb="@drawable/slider"

回答13:

If you are using default SeekBar provided by android Sdk then their is a simple way to change the color of that . just go to color.xml inside /res/values/colors.xml and change the colorAccent.

<resources>
    <color name="colorPrimary">#212121</color>
    <color name="colorPrimaryDark">#1e1d1d</color>
     <!-- change below line -->
    <color name="colorAccent">#FF4081</color>
</resources>

回答14:

LayerDrawable progressDrawable = (LayerDrawable) mSeekBar.getProgressDrawable();

// progress bar line *progress* color
Drawable processDrawable = progressDrawable.findDrawableByLayerId(android.R.id.progress);

// progress bar line *background* color
Drawable backgroundDrawable = progressDrawable.findDrawableByLayerId(android.R.id.background);

// progress bar line *secondaryProgress* color
Drawable secondaryProgressDrawable = progressDrawable.findDrawableByLayerId(android.R.id.secondaryProgress);
processDrawable.setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);

// progress bar line all color
mSeekBar.getProgressDrawable().setColorFilter(Color.BLUE, PorterDuff.Mode.SRC_IN);

// progress circle color
mSeekBar.getThumb().setColorFilter(Color.GREEN, PorterDuff.Mode.SRC_IN);

I change the background_fill.xml

<?xml version="1.0" encoding="UTF-8"?>

Simple Way to change the seek bar color ...

 <ProgressBar
            android:id="@+id/progress"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:theme="@style/Progress_color"/>

Style : Progress_color

 <style name="Progress_color">
    <item name="colorAccent">@color/white</item> <!-- Whatever color you want-->
</style>

java class change ProgressDrawable()

seek_bar.getProgressDrawable().setColorFilter(getResources().getColor(R.color.white), PorterDuff.Mode.MULTIPLY);

回答17:

If you look at the Android resources, the seek bar actually use images.

You have to make a drawable which is transparent on top and bottom for say 10px and the center 5px line is visible.

Refer attached image. You need to convert it into a NinePatch.

回答18:

For those who use Data Binding:

1. Add the following static method to any class

   @BindingAdapter("app:thumbTintCompat")
   public static void setThumbTint(SeekBar seekBar, @ColorInt int color) {
       seekBar.getThumb().setColorFilter(color, PorterDuff.Mode.SRC_IN);
   }
   

2. Add app:thumbTintCompat attribute to your SeekBar

   <SeekBar
          android:id="@+id/seek_bar"
          style="@style/Widget.AppCompat.SeekBar"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          app:thumbTintCompat="@{@android:color/white}"
   />
   

That's it. Now you can use app:thumbTintCompat with any SeekBar. The progress tint can be configured in the same way.

Note: this method is also compatble with pre-lollipop devices.

回答19:

Small correction to the answer by @arnav-rao:

to make sure that the thumb is colored properly, use:

<style name="MySeekBar" parent="Widget.AppCompat.SeekBar">
    <item name="android:progressBackgroundTint">@color/colorBgTint</item>
    <item name="android:progressTint">@color/colorProgressTint</item>
    <item name="android:thumbTint">@color/colorThumbTint</item>
</style>

here android:thumbTint actually colors the "thumb"

回答20:

check this tutorial very good

https://www.lvguowei.me/post/customize-android-seekbar-color/

simple :

<SeekBar
                android:id="@+id/seekBar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:max="100"
                android:maxHeight="3dp"
                android:minHeight="3dp"
                android:progressDrawable="@drawable/seekbar_style"
                android:thumbTint="@color/positive_color"/>

then a style file:

<?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 android:shape="rectangle" >
            <solid
                android:color="@color/positive_color" />
        </shape>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape android:shape="rectangle" >
                <solid
                    android:color="@color/positive_color" />
            </shape>
        </clip>
    </item>
</layer-list>

回答21:

I wanted to create a style for the seekbar and then add the style to a theme so that I could have it applied to an entire theme while still allowing a substyle to override it. Here is what I did:

<!-- Blue App Theme -->
    <style name="AppTheme.Blue" parent="BaseTheme.Blue">        
        <item name="android:seekBarStyle">@style/SeekbarStyle.Blue</item>
        <item name="seekBarStyle">@style/SeekbarStyle.Blue</item> <!--This is essential for some devices, e.g. Samsung-->
</style>

<!-- Slider Styles -->
<style name="SeekbarStyle.Blue" parent="Widget.AppCompat.SeekBar">
        <item name="android:progressBackgroundTint">@color/material_blue_a700_pct_30</item>
        <item name="android:thumbTint">@color/material_blue_a700</item>
        <item name="android:thumbTintMode">src_in</item>
        <item name="android:progressTint">@color/material_blue_a700</item>
</style>

<style name="SeekbarStyle.Green" parent="Widget.AppCompat.SeekBar">
        <item name="android:progressBackgroundTint">@color/material_green_a700_pct_30</item>
        <item name="android:thumbTint">@color/material_green_a700</item>
        <item name="android:thumbTintMode">src_in</item>
        <item name="android:progressTint">@color/material_green_a700</item>
</style>

The above sets the Theme seekbar style to blue for all devices 21+ including Samsung (which need the seekBarStyle applied in addition to android:seekBarStyle; not sure why but I saw this issue firsthand). If you want all seekbars to keep the theme style and only apply the green seekbar style to a few widgets then add the following to the widget you want:

<SeekBar
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/AppTheme.Green"/>

For APIs < 21 (and >= 21) you can use the answer of @Ahamadullah Saikat or https://www.lvguowei.me/post/customize-android-seekbar-color/.

回答23:

With the Material Component Library version 1.2.0 you can use the new Slider component.

 <com.google.android.material.slider.Slider
       android:valueFrom="0"
       android:valueTo="300"
       android:value="200"
       android:theme="@style/slider_red"
       />

You can override the default color using something like:

  <style name="slider_red">
    <item name="colorPrimary">#......</item>
  </style>

Otherwise you can use these attribute in the layout to define a color or a color selector:

   <com.google.android.material.slider.Slider
       app:activeTrackColor="@color/...."
       app:inactiveTrackColor="@color/...."
       app:thumbColor="@color/...."
       />

or you can use a custom style:

 <style name="customSlider" parent="Widget.MaterialComponents.Slider">
    <item name="activeTrackColor">@color/....</item>
    <item name="inactiveTrackColor">@color/....</item>
    <item name="thumbColor">@color/....</item>
  </style>

You can also make it this way :

<SeekBar
    android:id="@+id/redSeekBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:progressDrawable="@color/red"
    android:maxHeight="3dip"/>

Hope it will help!
