Replacement fragments in in pagerView

`Facing one problem in android that I created a pager View and two fragments lets say fragment A and fragment B are attached...
My question is: There is a button in fragment A after clicking on that button I want to load fragment C which will be the replacement of fragment A in the same pager view how can it be done? But when I try below code content of Fragment C is shown over the fragment A ... can u help me with this please. I searched everywhere but didn't get the proper solution.
here is my code...
public class MainActivity extends AppCompatActivity implements Top_Fragment.OnFragmentInteractionListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar=findViewById(R.id.tool_bar);
setSupportActionBar(toolbar);
MyPagerAdapter myPagerAdapter = new MyPagerAdapter(getSupportFragmentManager());
ViewPager viewPager = findViewById(R.id.pagerView);
viewPager.setAdapter(myPagerAdapter);
TabLayout tabLayout=findViewById(R.id.tab_bar);
tabLayout.setupWithViewPager(viewPager);
}
class MyPagerAdapter extends FragmentPagerAdapter {
public MyPagerAdapter(#NonNull FragmentManager fm) {
super(fm, BEHAVIOR_RESUME_ONLY_CURRENT_FRAGMENT);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new Top_Fragment();
case 1:
return new FavoriteFrag();
}
return null;
}
#Override

return 2;
}
#Nullable

Fragment fragment=null;
switch (position){
case 0:
fragment=new DrikCategaryFrag();

FragmentTransaction ft=getSupportFragmentManager().beginTransaction();
ft.replace(R.id.frameContainer,fragment);
ft.commit();

I tried but cant achieve similar effect. I have problem is showing all child in at the same time. and also i cant able to achieve the select avatar scaled in high and rest in low. Please help me out, i want to implement quickly as possible without using any library because i want to understand how it can be implemented without it as of now. Thanks in advance.

Inside MainActivity , I want to call FirstTabFragment method [updateFirstFragmentValues()]
I tried adding TAG in FirstTabFragment ,
public static final String TAG ="FirstTabFragment.TAG";
Then I invoked in MainActivity like below , but Fragment always null.
public void invokeMethodFromFirstTabFragment() {
FragmentManager fm = this.getSupportFragmentManager();
FirstTabFragment fb=(FirstTabFragment)fm.findFragmentByTag(FirstTabFragment.TAG);
if (null != fb) {
fb.updateFirstFragmentValues();
}else{
L.m("Fragment is null===========");
}
}
Kindly advise , How to call "FirstTabFragment" method from inside "MainActivity"
Please note FirstTabFragment is not added directly to MainActivity ,
its added through "Home_Tab_Fragment".

Alright, reading all of the responses of yours, I get that you just simply need to pass data to a fragment upon creation and be able to execute some of Fragment's methods. Ok, simple enough:
IMessageFragment interface
public interface IMessageFragment {
/**
* Method to receive new message text
* #param text Message text to receive
*/
void updateMessageText(String text);
}
MessageFragment
public class MessageFragment extends Fragment implements IMessageFragment {
/**
* Bind views using ButterKnife
*/
#BindView(R.id.textView) TextView mTextView;
/**
* Bundle data
*/
private String mMessageText;
/**
* Unique id of bundle data
*/
private static final String MESSAGE_EXTRA_KEY = "f_message";
/**
* New fragment pattern. This is pretty much all the magic PLUS this
* looks by far better than `new Fragment()` upon instatiation
*/
public static MessageFragment newFragment(String message) {
// 1. Create new fragment
MessageFragment auctionFragment = new MessageFragment();
// 2. Create bundle for fragment params
Bundle args = new Bundle();
// 3. Put position
args.putString(MESSAGE_EXTRA_KEY, message);
// 4. Set arguments
auctionFragment.setArguments(args);
return auctionFragment;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.tutorial_fragment, container, false);
/**
* Bind views
*/
ButterKnife.bind(this, view);
// Update UI
updateUI();
return view;
}
/**
* Method to update value of mTextView
*/
private void updateUI() {
if(!mMessageText.equals("")) {
mTextView.setText(mMessageText);
}
}
#Override
public void updateMessageText(String text) {
mMessageText = text;
updateUI();
}
}
Stuff is pretty simple and the interface exists only for good code style and to support design patterns.

Edit:
You cannot directly access FirstTabFragment method from your MainActivity. Firstly you have to call Home_Tab_Fragment method from activity. Then from that method you can call FirstTabFragment method.
Here is strategy:
Step 1: Home_Tab_Fragment to FirstTabFragment communication
define an interface like this
public interface IHomeToFirstFragmentController{
void firstFragmentMethod();
}
Now implements the IHomeToFirstFragmentController in your FirstTabFragment. then you have to implements the firstFragmentMethod().
#overrride
void firstFragmentMethod(){
}
Call this firstFragmentMethod method from Home_Tab_Fragment using this way
YOUR_fragmentInstance.firstFragmentMethod();
Step 2: Activity to Home_Tab_Fragment:
define an interface like this
public interface IActivityToHomeTabController{
void callFirstFragment();
}
Now implements the IFragmentController in your Home_Tab_Fragment. then you have to implements the callFirstFragment().
#overrride
void callFirstFragment(){
YOUR_fragmentInstance.firstFragmentMethod();
}
Edit 2:
Call fragment using this way
((IFragmentController)YOUR_fragmentInstance).firstFragmentMethod();
Hope this will give you an idea about this topics. For more info visit this answer

First for all, you create interface :
public interface CallBackListener{
void onCallBack();
}
In Fragment
public MyFragment extends Fragment{
private CallBackListener mCallBack;
#Override
public void onAttach(Context context) {
AppCompatActivity activity;
if (context instanceof AppCompatActivity) {
activity = (AppCompatActivity) context;
try {
mCallBack= (CallBackListener ) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString() + " class must be implement" +
" OnBackFragmentListener");
}
}
super.onAttach(context);
}
}
Use :
mCallBack.onCallBack();
And in Activity, you must implements interface :
public MyActivity extends AppCompatActivity implements CallBackListener{
#Override
public void onCallBack(){
// Do somethings here...
}
}

Edittext automatically gets focus when move between pages in a view pager

I have an activity which hosts two fragments inside a view pager. I used the same layout to inflate those fragments. The layout has two edit texts placed inside a linear layout which is inside a relative layout. The problem is when I switch from fragment A to fragment B, he first edit text has focus in fragment A and when I return back from fragment B to fragment A, instead of the first edit text having focus, the second edit text gets the focus. How to solve it. I provide the layouts and source code below. I have not return any code inside the fragment classes.
Activity:
public class LoginActivity extends BaseActivity {
public static final String selectedTabPosition = "selectedTabPosition";
//Tab tag name
private static String TAB_1_TAG = "Email";
private static String TAB_2_TAG = "Mobile";

ScreenShots:
Before moving to FragmentB:
In Fragment B:
Return back to Fragment A from Fragment B:

You can disable the focus on the EditText during runtime of the fragment:
EditText et_email_view = (EditText) rootView.findViewById(R.id.et_email);
et_email_view.setFocusable(false);

Use requestFocus attribute to your first editText which will always cause that editText to gain focus.
Make following changes in your fragment_login.xml file,
<EditText
android:id="#+id/et_email"
android:layout_width="match_parent"
android:layout_height="#dimen/spacing_48">
<requestFocus />
</EditText>

For example in my case viewPager is covering editText. I set translationZ at editText(translationZ="2") and viewPage(translationZ="1") and it helped me.

move from a fragment to another in an activity

From what I understand from this thread, fragments can be easily replaced with another.
However in my case, I have 2 fragments combined in scrollable Activity, so when I say "move", I mean going from the fragment left to the right or right to the left without replacing any fragment with another. Is this somehow possible?

you could use ViewPager for that. And on your adapter class you will have to switch between the fragments via getItem(). Eclipse/new AndroidProject/ swipe with/out tabs. And check the example code generated by Android.

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSectionsPagerAdapter = new SectionsPagerAdapter(
getSupportFragmentManager());
mSectionsPagerAdapter.notifyDataSetChanged();
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
Fragment fragment = null;
switch(position){
case 0:
fragment = new GridApp();
break;
case 1:
fragment = new ListApp();
break;
}
return fragment;
}
#Override
public int getCount() {
return 2;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return "Select App";
case 1:
return "Selected Apps";
}
return null;
}
}
}
now create a class called GridApp and ListApp
GridApp class.
public class GridApp extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.gridpp,
container, false);
}
}
ListApp class
public class GridApp extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.listapp,
container, false);
}
}
and you are done.
