There are situations where clicking on view triggers some action that takes more time. For example, saving data to the database or updating data from the network. In this case, it is good (and in case of network calls mandatory) to perform these operations on background thread.
But how to prevent user to click multiple times and trigger multiple operations? There are some options to consider.
You can show an uncancelable dialog that will prevent unwanted clicks until it is dismissed. For example show this progress dialog with spinning wheel and hide it when the operation finishes.
