Make Seekbar thumb easier to grab

So I have a SeekBar but the little circle thumb thing is kind of hard to grab. Is there a way to make the hitbox larger? I don't necessarily care if the graphic itself looks any different -- I just want it to be grabbable.

Solution

  • You can customize the seekbar, Answered by Andrew, by changing the size of the Thumb. create layered-drawable with shape as placeholder thumb_image.xml

    <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
    <shape>
        <size
            android:height="40dp"
            android:width="40dp" />

        <solid android:color="@android:color/transparent" />
    </shape>
</item>
<item android:drawable="@drawable/scrubber_control_normal_holo"/>
</layer-list>

    The example shows the result below.

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

    Another good example here of Thumb customization.
