Android: SeekBar with custom drawable

I have SeekBar with custom drawable. Progress element is not rendered from left side exactly but it is moved to right. How can I avoid this?

seekbar.xml

seekbar_background.xml

seekbar_progress.xml

EDIT:

As mentioned in comments if there will be both widths same problem disappear. But I need make it with two different widths through drawable is it possible? Maybe with different shapes not just lines?

Answer by Mina Fawzy for Android: SeekBar with custom drawable

As it appear the issue in progress I think they both should be the same width

but you in progress make width = 4 android:width="4dp"

and seekbar width = 2 android:width="2dp"

just match them to be 2 or 4 dont use different values

I can not explain why this is an issue when drawing strokes, I think it has something to do with the strokes width, but I did not yet find the source to verify.

Fixing the Overlay

To remove the issue at hand, you can just set an inset on your left side. A value of 1dp or 2dp both work and the seekbar will be drawn properly.

Note: Using this approach there should be no risk that the background could be too short and not visible with low progress values, since the thumb would overlay and hide it in any case.

Try using a .9.png drawable of width 4dp (converted to px) .

Keep 1 dp at top and bottom transparent.

And add colour to the center 2 dp of your choice for the background.

This way both background and progress will be of same width but the background will look thinner than progress bar.

Try like this using android:layout_marginLeft="-3dp" or -2dp

Observation

When you create a line using shape drawable it leaves the left and right padding (from the view in which this drawable is being used.)equal to the half of its stroke width.

Workaround

You need to wrap your progress_background with an inset drawable and then set it as progress background. The inset can be like the following-

inset_seekbar_background.xml      

and your final seekbar.xml will be like-

Alternates

1.You can use an 9 path image for line as it is done in the default material design-

2.You can set the theme to your view with different color in android style as-

Here I have used all there options for Seekbars-

If your choices of color has a limit and is predefined. You can try to add XML files with Seekbars using different themes.

Something like this:

themed_seekbar_one.xml

themed_seekbar_two.xml

You can then inflate does views programatically like this:

SeekBar seekbar = (SeekBar)getLayoutInflater().inflate(R.layout.themed_seekbar_xxx, null);
