After that the next step is learn how to move from one Activity to another Activity using Intent. After learn about Activity, that they will learn about how to move from Activity to Fragment, and the Fragment to Activity
Move From Activity To Fragment
On this part, i will show you two ways how to move from Activity to Fragment:
1. Using Activity For Place a Fragment
We call the fragment in Activity's layout. So when you try to access a Fragment, just call the Activity where you set the fragment using Intent.
Here is the example :
Create a XML file name it as activity_main.xml
Layout activity_main.xml will used on class MainActivity. Code for class MainActivity.java looks like the follows :
Well, above is a class that we used as the first page when application is opened
Create a class Fragment and name it as NameFragment.java, Here is the code :
Next create layout for Fragment NameFragment name it as fragment_name.xml, here is the code :
OK, class Fragment already done. So how can we call Fragment NameFragment from MainActivity?
Create a new layout name it as activity_for_fragment_name.xml
Take a look at above code, inside tag
com.putuguna.fragmenttoactivity.NameFragment contains name of package project and name of class.
com.putuguna.fragmenttoactivity : name of package project that we created
NameFragment : name of class Fragment that we created
Then create a java class for Activity NameFragment, name it as ActForFragmentNameActivity.java, the code is looks like the follows :
As we can see there is not special initialize code inside class MainActivity, it just initialize of its layout. But when this class is loaded, by using attribute class inside tagline fragment, then automatically its fragment will loaded
Calling Fragment NameFragment from MainActivity, you can do it look like the following code :
The part of the code above available on MainActivity, inside button onClick
2. Without using Class Activity
If you create fragment without create its Activity, simple do like the following code :
Move from Fragment To Activity
If you try access an Activity from a Fragment, simply like the following code :
Yang perlu diperhatikan adalah :
.... new Intent(getActivity(), .....), getActivity() as Activity of Fragment, because on Intent's constructor required Activity and destination class , so we use getActivity() to take fragment's activity.
And also before you do startActivity(), first write getActivity() then startActivity().
That's all. Sorry for worst english. Thank you.
