Yes, the believers in Acts 2 continued to meet in the temple. The temple was still operating, and these Jewish believers, under the heavy arm of Judaism, gathered there. They also held all things common, selling possessions and goods to share among all.

Les explains that the early Jewish believers in Acts 2 were still under the heavy arm of Judaism, and the temple was still operating. He points out that they met in the temple. They had all things common, sold their possessions and goods, and parted them to all, not just men but women and widows as well. They were living out of a common kitty, expecting the kingdom to be set up soon. Les notes that even Barnabas later sold his land on Cyprus and brought the money to the kitty in Jerusalem. They were ready to give up private holdings because they believed the kingdom was just over the horizon.
