Step 2) Now add a function and pass an argument 'View view'. So just add or import these three libraries which are first import, second is import which we will use to change fragment or remove fragment, and the third library called. Step 1) Now go to the mainactivity.java and in here, we need to import some library to add some fragment, fragment manager and fragment transaction.

Step 11) Now you can also add the default fragment here so that whenever we will run our activity.So what we are going to do is, we are going to add a default fragment to it so just write android: name and we will add a default fragment and inside double quotes go to your fragment_one.xml file in here and just copy the name of the fragment from here or context, and paste this end the design part of our fragment therefore now let’s add some code to our mainactivity.java file, Step 10) Now you can add some more properties to this fragment like ID, for example, we will name as fragment_place. So we want to add match parent for the height and width.

Step 9) Now once again go to my activity_main.xml file and try to add this fragment in this remaining space in the Android Activity, so just go to textview and just add a fragment and this will create a fragment for you and you can choose which width and layout height you want, Return inflator.inflate (R.agment_fragment_one, contain public class FragmentOne extends Fragment View onCreate (LayoutInflater inflater, ViewGroup contain Step 8) Now you will be able to see inside your java folder, that there are two java file will be created FragmentOne and FragmentTwo that are fragmentone.java, just click this fragmentone.java file and in here you will be able to see this all code is created by Android Studio for you, So in order to make things simple just remove all the code and just leave one method here and this method will be onCreateView method and all the other method and we will do the same for FragmentTwo also. Step 7) Now let’s change the background colour of these two fragments so that we can recognize the fragments, so, for example, FragmentTwo we will just change the background colour to little bit reddish and for FragmentOne green And now we have 2 fragments created FragmentOne and FragmentTwo Step 6) In the same way we will add the second fragment so right click on layout -> new fragment -> blank fragment and name it as FragmentTwo. Now just click this layout folder and right click it and create new and we are going to create a new fragment which is a blank fragment and we will name this fragment as, for example, FragmentOne and click finish. So go to your app folder and inside this app folder, go to resource directory and inside this go to this layout folder where your activity_main.xml file is there. Step 5) Now we have to add some fragment to this project. Step 4) Now what we are going to do is we are going to take two buttons and we are going to, listen for these button click events and we will try to open two different fragments using these two buttons therefore rename these buttons as, for example fragment 1 and the second button as fragment 2 and change the property, layout width property of these two fragments to Fill or Match parent. So for fixing this error, what you need to do this you need to go to the property here and in there, you go to the property called orientation and change the orientation to vertical and this error will be gone. Step 3) Now when you change this layout here from relative layout to linear layout, you will be able to see an error, this error is nothing but, you know, whenever you add some child to you activity then this error can occur. Step 2) So now our blank project is created and going to your textview of this java file activitymain.xml and instead of relative layout, we are going to use linear layout here, therefore, change this relative layout to linear layout. Read Here Start New Activity on Button Click in Android Step 1) First create a new project for this fragment example name project as Fragment.Then choose the default, minimum STK and, note that we can use fragment above API 11 so it’s better to use API 11 or above to use fragment in a better way so we will use API 11 or android 3.0 which is honeycomb and then click next and create a blank activity, click next and then leave all the field as default and click finish.

Please follow the steps below in order how to use fragments in Android: An activity can contain a various number of fragments. The biggest advantage of the fragment is that it simplifies the task of creating UI for multiple screen sizes. We can combine multiple fragments in a single activity in order to build a multi-pane UI and reuse a fragment in multiple activities. A Fragment represents a behaviour or a portion of user interface in an Activity.
