ExoPlayer - changing thumb in DefaultTimeBar
I didn't found an option to set a thumb icon in DefaultTimeBar.
You can copy DefaultTimeBar and customize the thumb by changing drawPlayhead(Canvas canvas) method.
Also uou can change it color by adding exo_playback_control_view.xml. (scrubber == thumb)
<com.google.android.exoplayer2.ui.DefaultTimeBar
android:id="@id/exo_progress"
android:layout_width="0dp"
android:layout_weight="1"
app:scrubber_color="@color/scrubberColor"
app:played_color="@color/playedColor"
app:unplayed_color="@color/unplayedColor"
app:buffered_color="@color/bufferedColor"
android:layout_height="26dp"/>

========== UPDATE ================
Following properties could be used in order to change the scrubber drawable:
app:scrubber_drawable="@drawable/ic_scrubber"
app:scrubber_enabled_size="24dp"
This option was added by ExoPlayer team after ticket was raised.
app:scrubber_drawable="@drawable/ic_scrubber"
