List view inside Fragment is not getting populated

I am trying to populate a ListView and display it under Fragment. I see that the count is returning correctly (greater than 0) after calling the adapter. Initially I had an issue with getView not being called but it was in a way resolved by changing layout_height to wrap_content as suggested by one of the article. I see that getView is now called while swiping for one Fragment to another. But getView doesn't get called when the Fragment is initially loaded. and also I don't ListView is displayed on screen regardless of any action.
First Fragment:
public class OneFragment extends Fragment {
public OneFragment() {
// Required empty public constructor
}
//private ListView mListView;
GridView grid;
String[] web = {
"Doctors","Movies","Dentists"} ;
int[] imageId = {
R.mipmap.doctors,
R.mipmap.dentists,
R.mipmap.restaurants
};
#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_one, container, false);
int iconSize=getResources().getDimensionPixelSize(android.R.dimen.app_icon_size);
CustomGrid adapter = new CustomGrid(view.getContext(), iconSize);
GridView gridview = (GridView) view.findViewById(R.id.grid);
gridview.setAdapter(adapter);
gridview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(view.getContext(), "You Clicked at " +web[+ position], Toast.LENGTH_SHORT).show();
ListItemMainFragment nextFrag = new ListItemMainFragment();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(((ViewGroup) getView().getParent()).getId(), nextFrag);
ft.setTransition(FragmentTransaction.TRANSIT_NONE);// it will anim while calling fragment.
ft.addToBackStack(null); // it will manage back stack of fragments.
ft.commit();
}
});
return view;
}
}
Next Fragment:
public class ListItemMainFragment extends Fragment implements Item.DataListener {
private ListView mListView;
private ItemAdapter adapter;
public ListItemMainFragment() {
// Required empty public constructor
}
#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.list_item_main, container, false);
mListView = (ListView) view.findViewById(R.id.item_list_view);
mListView.setAdapter(adapter);
//final String DBReference = "all/" + position + "/" + web[+position];
final String DBReference = "all/0/Doctors";
Item.getRecipesFromDB(ListItemMainFragment.this, DBReference);
return view;
}
#Override

I am not sure what you wanted by Item.getRecipesFromDB(ListItemMainFragment.this, DBReference);
as there is no code regarding "Items" it your Fragment.
But it think it doesn't populate your ListView.
So after ListView initialisation you have to create an adapter (it is missing in your onCreateView). And then set it onto ListView.
You also may try to call newDataReceived() from onCreteView.
But I suggest you to create the Adapter in onCreteView and then in newDataReceived() you can just update data and call notifyDataSetChanged() instead of creating new one each time

Dynamically inserting list items to listview in android

Friends i'm new to android and learning on my own. I was creating invoice manager app for learning. Here products are added by the admin and that is working fine. User has only permission to create invoice. When user arrives into create_invoice activity he has set of frame layouts in which one is for adding items. When user presses the frame layout he is made to see another activity where he can find all set of list items along with the product price in List view which admin has added. Now when user presses an item he is again brought back to create_invoice activity and a alert box appears which asks the qty required. When user enters the qty and clicks OK button, for the first the list item is displayed properly as i require. But when i add second item, 1st item gets replaced. So now my problem is how can i resolve this problem.. Guys please help me. Codes you people find may be very silly but i'm still learning. Thanks in advance.

Add item to your list that you're using in adapter and (after verifying adapter is not null ) call method notifyDataSetChanged () on adapter object.

create_invoice activity
//arraylist
ArrayList<invoice_product_list> productList = new ArrayList<>();
//customAdapter
customAdapterInvoice = new custom_adapter_invoice
(Create_invoice.this, productList);
customAdapterInvoice.addProduct(products)
custom Adapter
public class custom_adapter_invoice extends ArrayAdapter <invoice_product_list>
{
ArrayList<invoice_product_list> productList = new ArrayList<>();
public custom_adapter_invoice(Context context,
ArrayList<invoice_product_list> product_details) {
super(context, R.layout.custom_row_invoice_item, product_details);
this.productList =product_details
}
public void addProduct(Product products
productList.add(products);
notifyDataSetChanged();
}
......
}

No,it does not change anything. If you want the latest method of working then I would prefer RecyclerView to custom list adapter. this link is very good for recyclerview

how to hide view appear on top of previous selected row on click of another row inside GridView in android

I have a Fragment with custom Adapter extending BaseAdapter that manages a GridView.
I want to show images on each row of the GridView and onClick of each cell, I want to open a translucent view on top of that particular image which will show image details.
Problem is that when I click on the image, a translucent view opened on top of the image but when I click on next image then a translucent view opened on previous images is not hiding,it still appears over the first images..
See the following code
My Fragment
public class ProductFragment extends Fragment {
String ss = null;
GridView gridView;
ArrayList<ProductParameterBO> productlist;
GridViewCustomAdapter gridViewCustomAdapter;

Intent intent = new Intent(getActivity(),SplitViewActivity.class);
intent.putExtra("firstTab","1stTabs");
startActivity(intent);
}
});

Am I missing something? kindly help me to resolve this issue. I want a screen something like that. Am I doing right to open tranlucent screen on top of image and how to hide or make visivility gone on click of other images inside my Adater class.Any help would be appreciated in advanced

You can do one of two things.
1. Use a flag
NOTE this code is untested.
You can create an encapsulated flag in your ProductParameterBO object to determine the visibility of your overlay view. Something like the following
boolean mInformationViewVisible = false;
public void setInformationViewVisible(boolean visible) {
mInformationViewVisible = visible;
}
public boolean isInformationViewVisible() {
return mInformationViewVisible;
}
Then use that in your getView method to set the visibility of the view.
#Override
public View getView(int position,View convertView,final ViewGroup parent) {
...
holder.myImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for(int itemPosition = 0; itemPosition < availList.size(); itemPosition++) {
if(itemPosition != position){
availList.get(itemPosition)
.setInformationViewVisible(false);
}
availList.get(itemPosition).setInformationViewVisible(true);
}
});
if (currentItem.isInformationViewVisible()) {
holder.rl.setVisibility(View.VISIBLE);
} else {
holder.rl.setVisibility(View.GONE);
}
...
}
2. Switch to RecyclerView
The second and better option is to switch to RecyclerView. This view is specifically built for individual interaction with items in your Adapter. It gives you more power over the View in terms of animations and removal/adittion of items to the adapter. You can read more on it here and here.
It is very likely that the app in the image you attached is using RecyclerView to manage their content. The code to manage the selected info view will be very similar in RecyclerView to what I posted for the ListView, the only difference would be that you would pass the OnClickListener to the RecyclerView.ViewHolder and set it to the info view in there in stead of in the getView() method. I highly recommend using this approach as it will benefit you in the future of your app.

In ProductParameterBO, you can keep a boolean member variable, and in getView() and if one image is clicked, you can set the boolean variables from that list as false, except the one you clicked. If the variable is true, it will display the image details, and if the variable is false, you can set the visibillty of the translucent view as Invisible of that particular position.
#Override
public View getView(int position,View convertView,final ViewGroup parent) {
View row = convertView;
final TeeTimeHolder holder;
if (row == null){
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.grid_row,parent,false);
holder = new TeeTimeHolder();
holder.myImage =(ImageView)row.findViewById(R.id.imageView10);
holder.name =(TextView)row.findViewById(R.id.textView47);
holder.edit =(TextView)row.findViewById(R.id.textView49);
holder.rl =(RelativeLayout)row.findViewById(R.id.img_ovrly);
row.setTag(holder);
}
else {
holder =(TeeTimeHolder)row.getTag();
}
holder.name.setText(availList.get(position).getParameterName());
holder.myImage.setImageResource(R.drawable.toi);
holder.rl.setVisibility(View.GONE);
holder.myImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View rows = null;
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rows = inflater.inflate(R.layout.image_overlay,parent,false);
// holder.rl = (RelativeLayout)rows.findViewById(R.id.img_ovrly);
// holder.rl.setVisibility(View.VISIBLE);
for(int i=0;i<availList.size();i++){
if(i!=position){
availList.get(i).flag=false;
}
}
availList.get(position).flag=true;
}
});
if(availList.get(i).flag){
holder.rl.setVisibility(View.VISIBLE);
}else{
holder.rl.setVisibility(View.INVISIBLE);
}
return row;
}

Removing a cardview item inside a recycler view if it is null

I have a recycler view in which I populate a cardview consists of an image and two text fields. It works fine. What i want to know is there some way to remove an image from cardview if it is null (and not showing the blank space for image)and just show the text fields for that specific item in recycler view.
I am parsing a JSON service containing images and text. But some of the images are missing while parsing data and I want to remove that image space while displaying data.
Below is my Cardview.xml i am using inside Recyclerview adapter.

CustomViewHolder holder = new CustomViewHolder(view);
return holder;
}

public void onBindViewHolder(CustomViewHolder holder, int position) {
Data current = dataArray.get(position);
holder.textView1.setText(current.heading);
holder.textView2.setText(current.date);
holder.textView3.setText(current.brief);
// Using picasso to fetch image as the user scrolls down ... No need to store
// all the images during start up.
Uri uri = Uri.parse(current.getLImage());
//System.out.println("URIiii issss::::"+uri);
Picasso.with(context).load(uri).into(holder.image);
// Animation
setAnimation(holder.relativeLayout, position);
}
#Override
public int getItemCount() {
return dataArray.size();
}
public class CustomViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
ImageView image;
RelativeLayout relativeLayout;
TextView textView1, textView2, textView3;
public CustomViewHolder(View itemView) {
super(itemView);
textView1 = (TextView) itemView.findViewById(R.id.heading);
textView2 = (TextView) itemView.findViewById(R.id.date);
textView3 = (TextView) itemView.findViewById(R.id.brief);
image = (ImageView) itemView.findViewById(R.id.imageView);
}
#Override
public void onClick(View v) {
}
}
private void setAnimation(View viewToAnimate, int position) {
// If the bound view wasn't previously displayed on screen, it's animated
if (position > lastPosition || position < lastPosition) {
Animation animation = AnimationUtils.loadAnimation(context, android.R.anim.slide_in_left);
viewToAnimate.startAnimation(animation);
lastPosition = position;
}
}
}
What i really want is to remove the imageview item inside carview if it is null. I am relatively new to android, so any guideline would be highly appreciated.

Try with this.
If your Image URI is null.
if(uri == null){
Picasso.with(this.context).cancelRequest(holder.image);
holder.image.setVisibility(View.GONE);
}
Hope this helps you.

check two things for this,
first check your limage is null or not, if it is null than hide your image view.
one another thing is check image is already exists on your server url. if not exists on server hide your image view.
you can try below code for that,
if(current.getLImage() == null || !imageExists(**yourImageUrl**)){
Picasso.with(this.context).cancelRequest(holder.image);
holder.image.setVisibility(View.GONE);
}
public static boolean imageExists(String URLName){
HttpClient client= new DefaultHttpClient();
HttpHead headMethod = new HttpHead(urlToImage);
HttpResponse response = client.execute(headMethod);
if(response.getStatusLine().getStatusCode== HttpStatus.SC_NOT_FOUND) {
return false;
} else {
return true;
}
}

Row layout not inflated in Android

VerbData[1] = new Verb("machen","mache","machen","mache","machen","mache","machen");
VerbData[2] = new Verb("machen","mache","machen","mache","machen","mache","machen");
//pass data to adapter
VerbAdapter adapter = new VerbAdapter(this,R.layout.row_verbs,VerbData);
listViewVerbs = (ListView)findViewById(R.id.list);
listViewVerbs.setAdapter(adapter);
listViewVerbs.setOnItemClickListener(new AdapterView.OnItemClickListener() {

from activity_verbs and it works like a charm for me:
I uploaded my test-project with your code to DropBox, feel free to download it:
