I was reading a good post written by Luis G. Valle about SearchViews and he explains two lifecycle ways:
- Default: searchable activity receives a call to
onCreatewith anACTION_SEARCHintent. This will create two instances of your searchable activity (one on top of the other). - If you set
android:launchModetosingleTop: searchable activity receives a call toonNewIntentwith anACTION_SEARCHintent.
Commonly, a new activity is opened during a search and it could be good to keep a history of searches, each search done is a activity opened. If you don’t want that your app works in this way, you can set your activity launch mode as singleTop (I’ve explained a little about it here), and your app won’t need to open a new activity, but you can get the ACTION_SEARCH intent on the same activity, specifically on the onNewIntent() method.
Just to complement, I have another way that I’ve used in my apps to try. I really don’t think it is a better way than the second way explained by Luis but, keeping the first way, I intercept the intent on the method onStartActivity. Something like this:
| @Override | |
| public void startActivity(Intent intent) { | |
| if (Intent.ACTION_SEARCH.equals(intent.getAction())) { | |
| //Do something with the query… | |
| } else { | |
| super.startActivity(intent); | |
| } | |
| } |
In this way I avoid that a new activity is opened if the intent is related to search.
