I'm using a FrameLayout
where I have a GLSurfaceView
at the bottom and a few View
s on top of it. One of those View
s is a TextView
that displays the current score.
Here's how I'm updating the score TextView
based on what happens in my game loop: whenever an event happens that increases the score, I call activity.runOnUiThread(updater)
, where activity
is the activity that has the above FrameLayout
(my main game activity) and updater
is just a Runnable
that increments the score. From my understanding, using runOnUiThread()
from the OpenGL thread is standard practice - otherwise you'll get an exception, I can't remember its name.
The problem is that there's a very noticeable lag between the event and the score update. For example the character gets a coin, but the coin count is not updated quickly. I tried summing all the score events from my game loop and calling runOnUiThread()
only once per loop, but it doesn't seem to make much of a difference - the lag is still noticeable.
How can I improve my design to avoid this lag?
