[SOLVED] Using activity.finish in up button

Using activity.finish in up button

I want to define an up button for my android application to go to parent activity. From some resources I found this code when up-button clicked:

NavUtils.navigateUpFromSameTask(getActivity());

But I had a problem and it was that my activity needs some data for creation (Intent extras) and for this reason I replaced with this code:

getActivity().finish();

But some feeling tells me this is not a correct way for reaching to parent activity and maybe I will face to some runtime errors later. What do you think what should I do?

Solution

  Intent myIntent = new Intent(sourceActivity.this,targetActivity.class);
  myIntent.putExtra("NameKey", yourValue); // for send a Value with a key name. yourValue can be every type value
  startActivity(myIntent);
  this.finish();
  // and for receive value from target activity
  Bundle extraGet = getIntent().getExtras();
  String receiveValue = extraGet.getString("NameKey");

also you can define public static your variable that can use it to every class and activities

i think you want this:

 Intent intent = NavUtils.getParentActivityIntent(this);
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 NavUtils.navigateUpTo(this, intent);
