Ok, all codes here.iam new in android . so i dont know whtais the problrm here. some time fragment and activity contents are mixing..
the problems are only in xml file.not in programattic code

Try this code..
set both fragment background color into root attribute it means Relative layout tag.
android:background="#android:color/white"
and card view refer this link it give good demo for that..
https://www.androidhive.info/2016/05/android-working-with-card-view-and-recycler-view/
add fragment into activity then call onCreate method in below code..
Fragment fragment = new MainFragment();
getSupportFragmentManager().beginTransaction()
.replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

Master/Detail layout not rendering

I'm trying to make an app that fetches a book list from an API and displays it on the master list and, upon clicking, it displays the details. It works fine with mobiles, but I can't get it to work with tablets and since there's no error I can't find out where I went wrong.
On tablets it renders as if on a phone instead of rendering the two pane view.
I'm using a single activity with fragments.
"Main" activity:
public class ItemListActivity extends AppCompatActivity {
public static FragmentManager fragmentManager;
private boolean isTwoPane = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_item_list);
determinePaneLayout();
fragmentManager = getSupportFragmentManager();
if(isTwoPane){
//fragmentManager.beginTransaction().add(R.id.master_dual, new ItemsListFragment()).commit();
fragmentManager.beginTransaction().add(R.id.flDetailContainer, new ItemDetailFragment()).commit();
fragmentManager.beginTransaction().add(R.id.fragmentContainer, new ItemsListFragment()).commit();
} else {
fragmentManager.beginTransaction().add(R.id.fragmentContainer, new ItemsListFragment()).commit();
}
}
private void determinePaneLayout() {
FrameLayout fragmentItemDetail = (FrameLayout) findViewById(R.id.flDetailContainer);
// If there is a second pane for details
if (fragmentItemDetail != null) {
isTwoPane = true;
}
}
Item List Fragment:
public class ItemsListFragment extends Fragment {
private ArrayList<Book> bookList;
private ArrayList<String> bookNames;
private ArrayAdapter<Book> bookArrayAdapter;
private ArrayAdapter<String> bookNamesAdapter;
private ApiInterface apiInterface;
private ListView lvItems;
private static final String bookKey = "newBook";
private static Book nBook;
public ItemsListFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_items_list,
container, false);
return view;
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
lvItems = view.findViewById(R.id.lvItems);
bookNames = new ArrayList<>();
//bookNames.add(0, "Gabriel");
apiInterface = ApiClient.getApiClient().create(ApiInterface.class);
Call<ArrayList<Book>> call = apiInterface.getBooks();
call.enqueue(new Callback<ArrayList<Book>>() {
#Override
public void onResponse(Call<ArrayList<Book>> call, Response<ArrayList<Book>> response) {
bookList = new ArrayList<>();
bookList = response.body();
bookArrayAdapter = new ArrayAdapter<>(getContext(),
android.R.layout.simple_list_item_activated_1, bookList);
lvItems.setAdapter(bookArrayAdapter);
}
#Override
public void onFailure(Call<ArrayList<Book>> call, Throwable t) {
}
});
lvItems.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
nBook = bookList.get(i);
if(view.findViewById(R.id.flDetailContainer) != null){
ItemListActivity.fragmentManager.beginTransaction().replace(R.id.flDetailContainer, ItemDetailFragment.newInstance(nBook)).addToBackStack(null).commit();
} else {
ItemListActivity.fragmentManager.beginTransaction().replace(R.id.fragmentContainer, ItemDetailFragment.newInstance(nBook)).addToBackStack(null).commit();
}
}
});
}`
Item Detail Fragment:
public class ItemDetailFragment extends Fragment {
private static final String bookKey = "newBook";
private static Book nBook;
private TextView title;
private TextView isbn;
private TextView currency;
private TextView price;
private TextView author;
public static ItemDetailFragment newInstance(Book book) {
ItemDetailFragment fragment = new ItemDetailFragment();
Bundle args = new Bundle();
args.putSerializable(bookKey, book);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
nBook = (Book)getArguments().getSerializable(bookKey);
Log.v("BundleOK", "BundleOK");
} else {
Log.v("Bundle Nulo", "Bundle nulo");
}
}

I've been cracking my head for 5 days now, so any help is really appreciated! I tried a number of tutorials and searched SO thoroughly but no go!
Cheers!

I believe you have two copies activity_item_list.xml layout file and one is res/layout/ folder and another one is in res/layout-sw600dp/ folder.
sw600dp --> Screen width above 600dp use this layout else if less than 600dp use default layout file.
And also you make sure keep same attribute ids same in both the layout files.

It's hard to tell exactly due to the navigational structure of your app, but think the solution to your problem is to use the childFragmentManager inside of the ArtistBoardFragment. i.e, instead of
pageAdapter = new FragmentPagerAdapter(getActivity().getSupportFragmentManager()) ...
Use
pageAdapter = new FragmentPagerAdapter(getChildFragmentManager()) ...

Progress Bar not showing in fragment [ANDROID]

In my app i am using this library
https://github.com/DmitryMalkovich/circular-with-floating-action-button
to implement progress bar with floating action button. Its working on activity but when i included this layout in my fragment's layout progress bar doesn't show.
Here is my code for better explanation
Please guide me where i am going wrong
Any help will be appreciated.

make your customlayout at the bottom with the parent layout.
so your z index for that layout is at the top and it will be visible and gone that can be seen by you.

You need to use CoordinatorLayout with FAB .
Just put your FAB inside CoordinatorLayout.
As you can see library sample code suggests to use it too.

In a fragment implementation, the ListView below EditText disappears after setting keypad element (of EditText view) to hide

this is image while useing keypad
and this image after keypad was hidden
I use EditText but below it there is ListView. After typing text inputs in EditText and then press done or click back to hide keypad. Then the part of ListView behind the keypad disappeared and replaced by white area (cleared), why ?
NOTE: this fragment is under tablayout and viewpager and the fragment which contain the edit text and listview is launched from the main fragment

from manifest.xml search for your activity tag like this
<activity
android:name=".YourActivity"
android:label="#string/title_activity"
...>
</activity>
then add android:configChanges="keyboard|keyboardHidden" like that
<activity
android:name=".YourActivity"
android:configChanges="keyboard|keyboardHidden"
android:label="#string/title_activity"
...>
</activity>
EDIT
i found that my answer not completely right you may add
android:windowSoftInputMode="adjustNothing"
sorry about that

Why do I can slide to more than two times while I have only two tabs on Android?

I am learning how to use navigation drawer and navigation tab. I created an app that implement a navigation drawer on MainActivity and each item on navigation drawer will replace fragment on MainActivity to the corresponding fragment.
My first fragment provide two navigation tab using SlidingTabLayout and SlidingTabStrip. The other fragments are just a textview.
If I move from the first item to the second item and then back to first item again, my tab still show two tab, but in fact, I can slide more than two times and the content is not shown.
How do I fix this?
What it should be:
After I move to second drawer and then back to first drawer:
What happened after that:
You can see that I can slide more than twice and the content of fragments are not shown.

If you are correct about sliding more times than twice, then you need to set the override method getCount correctly (I realize you know). That's the only issue you need to worry about.
private String[] tabTitles = new String[] {"Tab One", "Tab Two"};
...
#Override
public int getCount() {
return tabTitles.length;
}
Note: I declared tabTitles differently as an array of String "String[]", widely accepted. The other style "tabTitles[]" may not work well with its methods like length.

Looking at your code more closely, I suspect objects TabOneFragment and TabTwoFragment is not working well. Normally override getItem returns the same static Fragment. And of course, I do not see that declaration or code for it.
My suggested try is (from your code):
#Override
public android.support.v4.app.Fragment getItem(int position) {
return TabsFragment.newInstance(position);
}
Note: With the above code, I don't see any use for TabOneFragment and TabTwoFragment, referenced in getItem(int position) in SamplePagerAdapter class. The TextView UI in layout fragment_tab_one.xml is only used for the tab texts. For those texts, the override getPageTitle(int position) can be used and is already coded.
