Two things. First I don’t think you are adding the data that you want to pass to the fragment correctly. What you need to pass to the fragment is a bundle, not an intent. For example if I wanted send an int
value to a fragment I would create a bundle, put the int
into that bundle, and then set that bundle as an argument to be used when the fragment was created.
Bundle bundle = new Bundle();
bundle.putInt(key, value);
fragment.setArguments(bundle);
Second to retrieve that information you need to get the arguments sent to the fragment. You then extract the value based on the key you identified it with. For example in your fragment:
Bundle bundle = this.getArguments();
if (bundle != null) {
int i = bundle.getInt(key, defaulValue);
}
What you are getting changes depending on what you put. Also the default value is usually null
but does not need to be. It depends on if you set a default value for that argument.
Lastly I do not think you can do this in onCreateView
. I think you must retrieve this data within your fragment’s onActivityCreated
method. My reasoning is as follows. onActivityCreated
runs after the underlying activity has finished its own onCreate
method. If you are placing the information you wish to retrieve within the bundle durring your activity’s onCreate
method, it will not exist during your fragment’s onCreateView
. Try using this in onActivityCreated
and just update your ListView
contents later.
