This is the fragment code:

On Button pressed I have this layout:

How can I fix this problem?

Solved removing layout_columnWeight and layout_rowWeight attributes and setting layout_width and layout_height in Cardview.

It's silly but in your fragment_space_edit_item.xml
<ImageView
android:id="#+id/myItemImg"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_marginTop="5dp"
android:layout_gravity="center"
android:clickable="true"
android:focusable="true"/>
android:background="#color/lightBeige"
android:contentDescription="#string/imageView"
background and contentDescription are Error if that is the case.

ViewPager with FragmentPagerAdapter Not showing Content

I am trying to use Fragment
This is my activity class:
public class InterfaceAct extends FragmentActivity implements View.OnClickListener {
private ViewPager mViewPager;
private List<Fragment> datas;
private ViewPagerFragmentAdapter viewPagerFragmentAdapter;
private LinearLayout mLLHome,mLLTimer,mLLEdit,mLLAbout;
private ImageView mImageViewHome,mImageViewTimer,mImageViewEdit,mImageViewAbout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activiy_interface);
initDatas();// Init Data For Fragments
initView();// Init Component
initEvent();// Sign for Click Listener
viewPagerFragmentAdapter=new ViewPagerFragmentAdapter(getSupportFragmentManager(),datas);// Init Adpater Class
mViewPager.setAdapter(viewPagerFragmentAdapter);
}
private void initDatas() {
datas=new ArrayList<Fragment>();
datas.add(new MyFragment1());
datas.add(new MyFragment2());
datas.add(new MyFragment3());
datas.add(new MyFragment4());
}
private void initEvent() {
mLLHome.setOnClickListener(this);
mLLTimer.setOnClickListener(this);
mLLEdit.setOnClickListener(this);
mLLAbout.setOnClickListener(this);
mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {//ViewPager Scrolling Switch Listner
#Override
public void onPageSelected(int arg0) {
int currentItem=mViewPager.getCurrentItem();
resetImag();
switch (currentItem) {
case 0:
mImageViewHome.setImageResource(R.drawable.home_yes);
break;
case 1:
mImageViewTimer.setImageResource(R.drawable.timer_yes);
break;
case 2:
mImageViewEdit.setImageResource(R.drawable.edit_yes);
break;
case 3:

}
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
private void initView() {
mViewPager = (ViewPager) findViewById(R.id.viewpager);
mLLHome = (LinearLayout) findViewById(R.id.ll_home);
mLLTimer = (LinearLayout) findViewById(R.id.ll_timer);
mLLEdit = (LinearLayout) findViewById(R.id.ll_edit);
mLLAbout = (LinearLayout) findViewById(R.id.ll_about);
mImageViewHome = (ImageView) findViewById(R.id.img_home);
mImageViewTimer = (ImageView) findViewById(R.id.img_timer);
mImageViewEdit = (ImageView) findViewById(R.id.img_edit);

}
#Override
public void onClick(View v) {

switch (v.getId()) {
case R.id.ll_home:
mViewPager.setCurrentItem(0);
mImageViewHome.setImageResource(R.drawable.home_yes);
break;
case R.id.ll_timer:
mViewPager.setCurrentItem(1);
mImageViewTimer.setImageResource(R.drawable.timer_yes);
break;
case R.id.ll_edit:
mViewPager.setCurrentItem(2);
mImageViewEdit.setImageResource(R.drawable.edit_yes);
break;

mImageViewTimer.setImageResource(R.drawable.timer_no);
mImageViewEdit.setImageResource(R.drawable.edit_no);

}
}
The ViewPagerFragmentAdapter Looks like this:
public class ViewPagerFragmentAdapter extends FragmentStatePagerAdapter {
private List<Fragment> datas;
public ViewPagerFragmentAdapter(FragmentManager fm,List<Fragment> datas) {
super(fm);
this.datas=datas;
}
#Override
public Fragment getItem(int position) {// Return View Object
return datas.get(position);
}
#Override
public int getCount() {// Return View Num
return datas.size();
}
#Override
public Object instantiateItem(ViewGroup container, int position) {// Init View
return super.instantiateItem(container, position);
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {// Destroy View
super.destroyItem(container, position, object);
}
}
The layout for the page, it includes a viewpager and also a menu bar in linear layout:
?xml version="1.0" encoding="utf-8"?>

I have four fragment prepared for viewpager(they are basiclly the same but with differnt layout), here is what the tab1 layout might look like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Chat"
android:textSize="30sp" >
</TextView>
</LinearLayout>
And I only got the menu bar when I run it, the viewpager is not set and I don't know why

Remove android:layout_weight="1" <Viewpager> and add android:orientation="vertical" to Linear layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="449dp"
></android.support.v4.view.ViewPager>

RecyclerView not displaying any data

In my Application I m having a RecyclerView in one of my Fragments in which I am getting response from a server using Reterofit. Every thing is fine but My RecylerView is not displaying any data returned from my service. Even the
int count = offerRecyclerAdapter.getItemCount();
of my adapter is returning the correct amount of data count returned from server.
Inside Fragment:
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
offersRecyclerView = (RecyclerView) view.findViewById(R.id.offer_recycler);
MotorCityArabiaGlobal global = (MotorCityArabiaGlobal) getActivity().getApplication();
ApiInterface apiService=global.getClient().create(ApiInterface.class);
Call<OfferResponse> call = apiService.getOffers(4);
call.enqueue(new Callback<OfferResponse>() {
#Override
public void onResponse(Call<OfferResponse> call, Response<OfferResponse> response) {
OfferResponse offers = response.body();
if(offers!=null){
List<Offer> result = response.body().getResult();
offerRecyclerAdapter = new OffersAdapter(getActivity(),result);
offersRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
offersRecyclerView.setItemAnimator(new DefaultItemAnimator());
offersRecyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), LinearLayoutManager.VERTICAL));
offersRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
#Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
return false;
}
#Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
#Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
});
int count = offerRecyclerAdapter.getItemCount();
offerRecyclerAdapter.notifyDataSetChanged();
}
}
#Override
public void onFailure(Call<OfferResponse> call, Throwable t) {
}
});
}
Adapter Class:
public class OffersAdapter extends RecyclerView.Adapter<OffersAdapter.MyViewHolder> {
private List<Offer> offersList= Collections.emptyList();
private LayoutInflater inflater;
Context ctx;
public OffersAdapter(Context ctx,List<Offer> offersList) {
this.ctx = ctx;
this.inflater = LayoutInflater.from(ctx);
this.offersList = offersList;
}
#Override

// View view = LayoutInflater.from(parent.getContext())
// .inflate(R.layout.offer_list_layout, parent, false);
View view = inflater.inflate(R.layout.offer_list_layout,parent,false);
return new MyViewHolder(view);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Offer offer = offersList.get(position);
holder.title.setText(offer.getOffer_title());
holder.price.setText(offer.getPrice());
holder.offerCount.setText(offer.getOffer_count());
}
#Override
public int getItemCount() {
return offersList.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title, offerCount, price;

add the line below in your onResponse after offersRecyclerView.addItemDecoration();
offersRecyclerView.setAdapter(offerRecyclerAdapter);
hope this helps.

You did not set the adapter to the RecyclerView. Use setAdapter method. See the following code,
List<Offer> results = new ArrayList<Offer>();
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
offersRecyclerView = (RecyclerView) view.findViewById(R.id.offer_recycler);
offersRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
offersRecyclerView.setItemAnimator(new DefaultItemAnimator());
offersRecyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), LinearLayoutManager.VERTICAL));
offerRecyclerAdapter = new OffersAdapter(getActivity(), results)
offersRecyclerView.setAdapter(offerRecyclerAdapter);
offersRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
#Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
return false;
}
#Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
#Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
});
MotorCityArabiaGlobal global = (MotorCityArabiaGlobal) getActivity().getApplication();
ApiInterface apiService=global.getClient().create(ApiInterface.class);
Call<OfferResponse> call = apiService.getOffers(4);
call.enqueue(new Callback<OfferResponse>() {
#Override
public void onResponse(Call<OfferResponse> call, Response<OfferResponse> response) {
OfferResponse offers = response.body();
if(offers != null){
List<Offer> result = response.body().getResult();
results.clear();
results.addAll(result);
offerRecyclerAdapter.notifyDataSetChanged();
}
}
#Override
public void onFailure(Call<OfferResponse> call, Throwable t) {

ViewPager in Custom Dialog

I have custom dialog to show which has instruction about how to use the app.I am using ViewPager for this inside my custom dialog layout.
I am getting error
java.lang.IllegalArgumentException: No view found for id for fragment FragmentForInstruction1.
I have created a method which is called in onCreate(Bundle savedInstanceState) {} method .The method inflates the layout for dialog.
private void showCustomDialogForInstruction() {
final Dialog dialog = new Dialog(MainActivity.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View dialogLayout = inflater.inflate(R.layout.dialog_layout_for_instruction_message, null, false);
layout.setAlpha(0.2f);
dialog.setCanceledOnTouchOutside(false);
dialog.setContentView(dialogLayout);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));
ViewPager viewPager=(ViewPager) dialog.findViewById(R.id.pagerInstruction);
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new FragmentForInstruction1());
adapter.addFrag(new Fragme`enter code here`ntForWelcomePage2());
adapter.addFrag(new FragmentForWelcomePage3());
adapter.addFrag(new FragmentForWelcomePage4());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new OnPageChangeListener()

return false;
}
});
dialog.getWindow().setBackgroundDrawable(
new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.show();
}
my view pager class:
public class ViewPagerAdapter extends FragmentPagerAdapter

You should create an adapter that extends FragmentPagerAdapter:
private class CustomPagerAdapter extends FragmentPagerAdapter {
public CustomPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new FragmentForInstruction1();
case 1:
return new FragmentForInstruction2();
case 2:
return new FragmentForInstruction3();
case 3:
return new FragmentForInstruction4();
default:
return new FragmentForInstruction1();
}
}
#Override
public int getCount() {
return 4;
}
}
While crating an instance of it, pass the getChildFragmentManager() instead of getSupportFragmentManager():
viewPager.setAdapter(new CustomPagerAdapter(getChildFragmentManager()));

Android: Multi Pane layout detail view appears by default

In my app, I have requirement of Multi Payne layout. In this layout, the first fragment is a ListView which shows the list of items. On click of the list item, a detail view will open up on the right hand side of the list item. But, in my case, when I run my app on tablet, the detail view appears along with ListView by default. While, I want that it should appear on click of the list item.
Below is my code:
Activity Class:
public class OrderActivity extends FragmentActivity implements
OnOrderSelectedListener {
private static final String TAG = "OrderActivity";
#Override
public void onCreate(Bundle savedInstanceState) {

setContentView(R.layout.order_details);
if (findViewById(R.id.fragment_container) != null) {

return;
}
OrderListFragment orderListFragment = new OrderListFragment();
orderListFragment.setArguments(getIntent().getExtras());
getSupportFragmentManager().beginTransaction()
.add(R.id.fragment_container, orderListFragment).commit();
}
}
#Override
public void onOrderSelected(int position) {
Log.d(TAG, "onOrderSelected called");
OrderDetailFragment detailsFrag = (OrderDetailFragment) getSupportFragmentManager()
.findFragmentById(R.id.order_detail_fragment);
if (detailsFrag != null) {
if (!detailsFrag.isVisible()) {
detailsFrag.setUserVisibleHint(true);
detailsFrag.updateOrderView(position);
}
} else {
OrderDetailFragment newFragment = new OrderDetailFragment();
Bundle args = new Bundle();
args.putInt(OrderDetailFragment.ARG_POSITION, position);
newFragment.setArguments(args);;
FragmentTransaction transaction = getSupportFragmentManager()
