Reveal a development bar when an Activity is loading
I’ve a ListActivity which launches some other Action determined by the record collection. This next Exercise must load a good bit of knowledge within the world-wide-web and therefore there is certainly a recognizable delay amongst when the consumer clicks on an product and in the event the Activity displays.
It is a problem given that I currently haven’t any way for you to indicate to the person that their click is becoming processed (even just shifting the colour on the chosen record merchandise is going to be sufficient but I am unable to look for a good way to perform that). Ideally I might have the ability to display screen an indeterminate ProgressDialog even though the next Exercise is loading.
For people with longer operations you really should not be engaging in them in onCreate in almost any case as this may freeze the UI (if the activity is exhibited). The UI set by onCreate isn’t going to seem also, the UI are unresponsive until eventually following the onCreate call finishes.
