The Fragment contains an edittext and a spinner.When we press the FAB(Floating Action Button) button,we open the MyFragment via Fragment Transaction,attaching it to a FrameLayout we shall define.We have two classes : one our MainActivity and another a MyFragment class.Fragments like Activities are special UI classes representing a window and so we cannot pass data directly like we do with ordinary classes. Hence we need to know how to pass data from the fragment to an activity. Fragments are subactivities and allow us have different screens without necessarily having to create many activities. Why Pass Data From Fragment To Activity No. One activity can host multiple fragments. What is a Fragment?Ī fragment is a subactivity with it’s own lifecycle. Today we look at how to pass simple data types from the fragment to activity.We pass data via Intent object. Lets continue with our android data passing series we had started earlier on.We had looked at how to pass data from activity to fragment and how to pass both a list/object from activity to activity as well as simple primitive data types. Example 1: Android Data Passing – Fragment To Activity Via Intent We will look at all these using practical examples in this lesson.
Thus we don’t just pass them data via constructors but in one of the following three ways: Even though activities and fragments are nothing but classes, they are considered special classes in android since they are fundamental to how android User interface works. Passing data between activities or fragments is one of the basic concepts you need to learn when you start doing android development.
