We have a shower with a single handle. Hot water only trickles out of the
faucet or shower head, but cold water works fine. Any suggestions as to
what could be wrong. We get hot water everywhere else in the house.

I would guess that there is a filter screen somewhere on the hot water
that is clogged.

You might try removing the valve cartrige, debris can get stuck inside

you could open up the fixture and flush out the fixture, flush out the
debris in stop valves below by opening and closing them with the water
running thru them.

here's a trick i used once:
if debris is blocking the sink hot, block the sink aerator, close
supply to water heater, open hot at the basement washtub, open the
fixture to full warm, and backflush the cold thru to basement washtub.
no improvement? swap instructions and backflush other line.
no improvement?
find all valve stops between main and the problem sink. remove and
replace debris inside and replace their broken and disintegrated rubber
washers blocking the line.
if you are still using old galvanized silver colored pipes, the
reduction of the inside diameter causing a restriction in flow is a
regular battle until replacement.

it take to get a gallon of hot? cold? warm?

If there is a pressure balancing unit (minimizes the impact of reduced
flow to prevent fluctuations in temp) it may not be moving, and may need
replacing.
