Android Refresh Activity When Returns To It

I need a little help with refreshing one of my activities in my application. I'm using tab host activity and connecting to web service and downloading some data from one of my chil

Solution 1:

Another tricky way to do this is just start your activity on onRestart()

@OverridepublicvoidonRestart(){
    super.onRestart();
    IntentpreviewMessage=newIntent(StampiiStore.this, StampiiStore.class);
    TabGroupActivityparentActivity= (TabGroupActivity)getParent();
    parentActivity.startChildActivity("StampiiStore", previewMessage);
    this.finish();
}

That should do the trick actually. (In this code I'm showing the way it's done when you are using a custom TabActivity manager.)

Solution 2:

You should handle the result of activity that you started with "startActivityForResult" in a parent activity in a method:

@overridepublicvoidonActivityResult(int requestCode, int resultCode, Intent data){
   //...
}

And depending on result you could just invoke again a code that is responsible for showing the information in your parent activity (may be you put it into onResume() method or like that).

I would suggest you to move all the logic responsible for information rendering to a separate method. And invoke it after you recieve the result. Instead of restarting your parent activity.

Solution 3:

If you start your second activity with the method startActivityForResult, when you return to the first activity, onActivityResult of the first activity will be called.

If you override it, you can refresh your activity from there.

See more information here and here

Solution 4:

Call child activity using startActivityForResult with request code,SetResult from the child Activity. And when the child activity is finished, you can update you parent activity in onActivityResult method

@OverrideprotectedvoidonActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stubsuper.onActivityResult(requestCode, resultCode, data);

      //Check the result and request code here and update ur activity class

    }

Here is an example http://rahulonblog.blogspot.com/2010/05/android-startactivityforresult-example.html

Solution 5:

Override onRestart() method inside activity you want to refresh, and recreate the activity

@OverrideprotectedvoidonRestart() {
    super.onRestart();
    this.recreate();
}
