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.

For future readers!

Starting from material-components-android 1.2.0-alpha01, you can use new slider component

ex:

Modify thumbSize, thumbColor, trackColor accordingly.

<com.google.android.material.slider.Slider
        android:id="@+id/slider"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:valueFrom="20f"
        android:valueTo="70f"
        android:stepSize="10"
        app:thumbRadius="20dp"
        app:thumbColor="@color/colorAccent"
        app:trackColor="@android:color/darker_gray"
        />

Note: Track corners are not round.

Answer 2

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 3

• 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 4

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"
    />

Answer 5

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 6

You can use the Slider in the Material Components Library.
Use these attributes to customize the colors.

• app:activeTrackColor: the active track color
• app:inactiveTrackColor: the inactive track color
• app:thumbColor: to fill the thumb

Something like:

    <com.google.android.material.slider.Slider
        android:id="@+id/slider"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:activeTrackColor="#ffd400"
        app:inactiveTrackColor="#e7e7e7"
        app:thumbColor="#ffb300"
        app:floatingLabel="false"
        .../>

It requires the version 1.2.0 of the library.
