I'm trying to learn how to use Fragments in android. I create the separate classes and layouts. I'm having trouble understanding how I'm supposed to link them all. What exactly goes in my Main class? Could someone please demonstrate exactly how to use fragments in a very basic way?
please read this first as, i think, i has the very basics. Below is an example:
MainActivity:
public class MainActivity extends Activity implements OnClickListener{
private final String TAG = "MainActivity";
private int btn00Clicks = 0;
private int btn01Clicks = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainactivity);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Fragment mSelectedFragment = null;
switch (v.getId()) {
case R.id.btn00:
Bundle mBundle00 = new Bundle();
String clicks00 = Integer.toString(btn00Clicks);
mBundle00.putString("btn00_clicks", clicks00);
mSelectedFragment = new Fragment00();
mSelectedFragment.setArguments(mBundle00);
if (mSelectedFragment != null) {
FragmentManager mFragmentManager = getFragmentManager();
mFragmentManager.beginTransaction()
.replace(R.id.fragment00ID, mSelectedFragment).commit();
}
btn00Clicks++;
break;
case R.id.btn01:
Bundle mBundle01 = new Bundle();
String clicks01 = Integer.toString(btn01Clicks);
mBundle01.putString("btn01_clicks", clicks01);
mSelectedFragment = new Fragment01();
mSelectedFragment.setArguments(mBundle01);
if (mSelectedFragment != null) {
FragmentManager mFragmentManager = getFragmentManager();
mFragmentManager.beginTransaction()
.replace(R.id.fragment00ID, mSelectedFragment).commit();
}
btn01Clicks++;
}
}
}
Fragment00.java:
public class Fragment00 extends Fragment {
private final String TAG = "Fragment00";
TextView mTv;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.fragment00, null);
return view;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
mTv = (TextView) getView().findViewById(R.id.fragment00Tv00);
if (getArguments() != null) {
String str = getArguments().getString("btn00_clicks").toString();
mTv.setText("the Button was clicked "+str+ " time(s)");
Log.i(TAG, "onActivityCreated(): "+str);
}else {
Log.i(TAG, "onActivityCreated(): getArguments() is NULL");
}
}
#Override
public void onAttach(Activity activity) {
// TODO Auto-generated method stub
super.onAttach(activity);
}
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
}
Fragment01.java:
public class Fragment01 extends Fragment {
private static final String TAG = "Fragment01";
TextView mTv;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.fragment01, null);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
mTv = (TextView) getView().findViewById(R.id.fragment01Tv00);
if (getArguments() != null) {
String str = getArguments().getString("btn01_clicks").toString();
mTv.setText("the Button was clicked "+str+ " time(s)");
Log.i(TAG, "onActivityCreated(): "+str);
}else {
Log.i(TAG, "onActivityCreated(): getArguments() is NULL");
}
}
}

In your main class you produce one or more fragments... While you produce each fragment it's pretty similar to Activity,but has its own lifecircle(google it).
here's example on fragment:
public class DummySectionFragment3 extends Fragment
{
public DummySectionFragment3() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View rootView = inflater.inflate(R.layout.exercise_layout,
container, false);
return rootView;
}
}
in OnCreateView() method you do what you usually do with activity.
My Main class contains SectionsPagerAdapter that switches between the fragments(A pager like in API samples)
create 2 or 3 fragments and just try it...
I didn't find any good example on it,so I just tried the above.
http://www.c-sharpcorner.com/UploadFile/2fd686/fragments/
Here's one good link with tabs and fragments.
You can also define your fragments in your xml.
Same as what LetsAmrIt posted, just another example:

The basic is like this:
Create one Activity and 2 Fragments.
If something happens in FragmantA something should change in fragmentB right. So the Activity links Fragment A and B together. What do you need for that: an Interface.
So create an Interface with a method which takes the right properties (don't forget the datatype). Now you can implement the interface in your activity.
After this you should initialize the interface in FragmentA in the onActivityCreated method. Perform the changes and send the data to the interfacemethod in the Activity. Create a reference to FragmentB using the FragmentManager. Now you can send the data/changes to FragmentB.
I hope you understand this ;). cheers
I made a sample project that doesn't use ViewPager and all the weird stuff, just the link between Activity and Fragment here on Stack Overflow and the same thing on Code Review to demonstrate it, click either links to see the project.
I used this link to get started
http://www.techotopia.com/index.php/Using_Fragments_in_Android_-_A_Worked_Example
This guy uses 2 different types of listeners and takes in the user input on the first fragment. The 2nd fragment outputs the data!
Goodluck!

I didn't understand if that actually what you trying to do but as i understood if you want the TextView moves automatically in one line to show the rest of it make this:
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:freezesText="true"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true" />
and in code after defining it's view make this:
textView.setChecked(true);
I want to change tab by swiping on the screen i am creating tabs using fragment tabhost but when i implement swiping feature in my project it doesn't open nested fragment in each tab means i am opening nested child fragment inside each tab.

You have to use a ViewPager. Read more at Android Developer website. You can find a lot of custom view pagers on Android Arsenal. This is the current standard, so you should use this over TabHost.
you can have a look at its demo in eclips go to
file->other->android Activity->tabbed activity
or learn the view Fliper from android developer website

Use this method in your activity for all fragment trancation
// For the Fragment Replace And AddtobackStack
void replaceFragment(Fragment fragment) {
String backStateName = fragment.getClass().getName();
String fragmentTag = backStateName;
FragmentManager manager = this.getSupportFragmentManager();
boolean fragmentPopped = manager
.popBackStackImmediate(backStateName, 0);
if (!fragmentPopped && manager.findFragmentByTag(fragmentTag) == null) {
// fragment not in back stack, create it.
FragmentTransaction ft = manager.beginTransaction();
ft.replace(R.id.container, fragment, fragmentTag);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.addToBackStack(backStateName);
ft.commit();
}
}
and use it like this whenever you need to go for nested fragment from one fragmnet
if (DetailsFragment.this.getActivity() != null
&& DetailsFragment.this.getActivity() instanceof HomeActivity)
((HomeActivity) DetailsFragment.this.getActivity())
.replaceFragment(cartfragment);
in the above suppose i am in details fragment and from here i want to go to cartfragment
then get the activitiy instance and cast it like the above
I want to save the user input of several fragments, i try with the method onSaveInstanceState to save the state and the method onActivityCreated to restore the data, my source is:

What is wrong?, the onSaveInstanceState not work, i try with putSerialize and nothing, please i appreciate your cooperation
If what you want to save is the Fragment state as is, take a look at this other answer, which is more an explanation than an example. You should be using the putFragment and getFragment methods from your getSupportFragmentManager() instance.
I recognize I've been a little late using these two bad boys on my own, but they're quite useful. Let me give you a hint on where to add them:
putFragment
Inside your Principal activity, add this directly in your onSaveInstanceState method. One call per fragment you want to save:
public void onSaveInstanceState(Bundle outState) {
Cliente fragment = getSupportFragmentManager().findFragmentById(R.id.myFragment);
getSupportFragmentManager().putFragment(outState, "cliente", fragment);
}
getFragment
You can (and should, actually) use getFragment inside the onCreate. Use the already passed savedInstanceState variable, and slightly change the way you init the fragment:
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction transaction = fm.beginTransaction();
Fragment startFragment = null;
if(savedInstanceState == null) { // first open
startFragment = new Cliente( );
} else { // rotation, change where the fragment was already there
startFragment = fm.getFragment(savedInstanceState, "cliente");
}
transaction.add(R.id.myFragment,startFragment);
transaction.commit();
This question already has answers here:
How to exit when back button is pressed?
(12 answers)
Closed 8 years ago.
In My MainActivity, I am adding three tabs named FragmentA, FragmentB and FragmentC.
In FragmentA tab, i am populating a list of contacts via list fragment and adding this fragment to backstack. Now when i click on any of list item, it displays the detailed fragment of that contact under the same tab FragmentA. When i press the back button, it goes back to list fragment of contact list.
On detail fragment, rather than clicking on back button, when i click on FragmentB tab , it is supposed to display a simple text, which is working fine. But When i click on back button now, it is supposed to close the application, but it goes back to list fragment, but remains inside of FragmentB tab, hence merges the both fragments.
In my MainActivity.java,
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if(tab.getPosition() == 0){
PM_Fragment pm_Fragment= new PM_Fragment();
FragmentManager manager= getFragmentManager();
FragmentTransaction frgTrans = manager.beginTransaction();
frgTrans.replace(android.R.id.content, pm_Fragment);
frgTrans.commit();
}
else if(tab.getPosition() == 1){
TabFragmentTwo tabFragmentTwo= new TabFragmentTwo();
Bundle bundle = new Bundle();
bundle.putString("Fragment", "2nd Fragment");
tabFragmentTwo.setArguments(bundle);
FragmentManager manager= getFragmentManager();
FragmentTransaction frgTrans = manager.beginTransaction();
frgTrans.replace(android.R.id.content, tabFragmentTwo);
frgTrans.commit();
}
else {
TabFragmentThree tabFragmentThree= new TabFragmentThree();
Bundle bundle = new Bundle();
bundle.putString("Fragment", "3rd Fragment");
tabFragmentThree.setArguments(bundle);
FragmentManager manager= getFragmentManager();
FragmentTransaction frgTrans = manager.beginTransaction();
frgTrans.replace(android.R.id.content, tabFragmentThree);
frgTrans.commit();
}
}

I would suggest you to clear the backstack of your fragment whenever you click on 2DFragment or 3D Fragment. At that click event first pop the backstack of fragment and then load the new fragment. It will work for sure.
Write the below code on click of your tabs before loading the new fragment.
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
fm.popBackStack();
EDITED:
Change code in your MainActivity as below:
else if(tab.getPosition() == 1){
FragmentManager manager= getFragmentManager();
FragmentTransaction frgTrans = manager.beginTransaction();
manager.popBackStack();
TabFragmentTwo tabFragmentTwo= new TabFragmentTwo();
Bundle bundle = new Bundle();
bundle.putString("Fragment", "2nd Fragment");
tabFragmentTwo.setArguments(bundle);
frgTrans.replace(android.R.id.content, tabFragmentTwo);
frgTrans.commit();
}
else {
FragmentManager manager= getFragmentManager();
FragmentTransaction frgTrans = manager.beginTransaction();
manager.popBackStack();
TabFragmentThree tabFragmentThree= new TabFragmentThree();
Bundle bundle = new Bundle();
bundle.putString("Fragment", "3rd Fragment");
tabFragmentThree.setArguments(bundle);
frgTrans.replace(android.R.id.content, tabFragmentThree);
frgTrans.commit();

When i go in inner fragments of tab1 , like from fragmentA -> Fragment B and From FragmentB -> fragmentC (and finally i am at fragmentC) , When i select Tab1 again i want to reload tabs and FragmentA should Apper.
Any help will be appreciated. I had gone through some of tutorials and coderepository but couldn`t found solution to my problem.
How Can i reload The content Of First tab when first tab is clicked again.
I had asked a question
When i go in inner fragments of tab1 , like from fragmentA -> Fragment B and From FragmentB -> fragmentC (and finally i am at fragmentC) , When i select Tab1 again i want to reload tabs and FragmentA should Apper.
I searched a lot and come to the conclusion , We can implement OnTabChangeListner and when any tab is clicked again we can reset it.(I was having need to reload tab when it is clicked 2nd time)

code for fragment A ...it is extend By Basefragment
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;

}
Code for BaseFragment is
extend this class with all sub fragment which you are going to add on (While adding fragment use myhomescreenActivity(This object) and call add Function in MyHomeScreen ):
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
public class BaseFragment extends Fragment {
protected MyHomeScreen myhomescreenActivity;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myhomescreenActivity = (MyHomeScreen) this.getActivity();
}
public boolean onBackPressed() {
return false;
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
}
}
This is the link of repository on Github for further understanding.......
https://github.com/thankimanish/TabUsingFragment
1.You can try moving your code inside the onCreate method to the onResume method so that every time fragment comes to front the code inside the onResume gets executed and reloads the frament.
2.You can also try overriding the onHiddenChanged method of the fragment and reload the fragment as soon as fragment becomes visible
