You can reduce the spacing between the bars that will automatically increase the width of bars.

BarDataSet set = new BarDataSet(vals, "Set A");
set.setBarSpacePercent(50f);

UPDATE v3.0.0:

As of this library version, you can control the bar width with the following method:

BarData barData = new BarData(...);
barData.setBarWidth(1f);

The number you provide for this method represents a certain interval on the x-axis. If your total axis has a range of e.g. 10k, and you set the bar width to 1000, the bar will cover 10% of the total x-axis range.
