Fragment viewpager No adapter attached; skipping layout

I tried a lot of solutions but no solution has worked for me.
I am getting data from the server and showing it inside a recycleview. The data shows fine but shows this error in the logcat
Access denied finding property "persist.vendor.log.tel_dbg"
E/RecyclerView: No adapter attached; skipping layout
E/RecyclerView: No adapter attached; skipping layout
sometimes when I refresh again and again the recyclerview becomes empty.
I am using viewpager consisting of 2 fragments inside a parent fragment.
this recycleview is using in a nested scrollview
some time data not showing
Code snippet:
homebuyer_adapter_recycler=new homebuyer_adapter_recycle(getActivity(), items);
LinearLayoutManager home = new LinearLayoutManager(getActivity());
home.setOrientation(LinearLayoutManager.VERTICAL);
allitemsgrid.setLayoutManager(home);
allitemsgrid.setAdapter(r);

In error it is saying that the Adapter for RecylerView is not attached. So, try to add adapter to the layout using:
recyclerView.setAdapter(categoryAdapter);

I am assuming homebuyer_adapter_recycler is your adapter.
According to that, you haven't really set your adapter as the logcat is specifying.
Add the below code instead of allitemsgrid.setAdapter(r);
allitemsgrid.setAdapter(homebuyer_adapter_recycler);
If my assumption or suggestion is wrong, it is okay. It is probably because your question is not very clear and does not provide the necessary details. Please provide more details such as the adapter class code and what is allitemsgrid, homebuyer_adapter_recycler and r.

Changing TextView of individual items in a ListView

I am in the making of a shopping list using a ListView with custom items with the posibility of increasing the amount of that item and also decreasing the amount.
At the moment, I get the right amount of items when I load them in to the shopping list, as can seen in the image below:
the image of the ListView and problem
But the problem occurs when I am trying to increase/decrese the amount of each item by clicking the buttons, only the last item in the ListView gets updated by the clicks.
The reason for this is because i am re-declaring the TextView for each item, and the others (probably?) doesn't get stored anywhere. So i read about "setTag()" and "getTag()" and tried to implement but this didn't work either (maybe beacuse i did it wrong).
I am using a custom class called "Item" which stores each item and the amount of that item.
Otherwise, this is the custom adapter and the .xml
public class ShoppingListAdapter extends ArrayAdapter<Item> {
int amount;
TextView amountText;
private Context mContext;
int mResource;
public ShoppingListAdapter(#NonNull Context context, int resource, #NonNull ArrayList<Item> objects) {
super(context, resource, objects);
mContext = context;
mResource = resource;
}
#NonNull
#Override
public View getView(final int position, #Nullable View convertView, #NonNull ViewGroup parent) {
//get the item information
String name = getItem(position).getName();
String brand = getItem(position).getBrand();
int id = getItem(position).getId();
String img = getItem(position).getImg();
amount = getItem(position).getAmount();
//all info
Item item = new Item(name,id,brand,img);
LayoutInflater inflater = LayoutInflater.from(mContext);
convertView = inflater.inflate(mResource,parent,false);
TextView tVName = (TextView) convertView.findViewById(R.id.textView2);
ImageView imgV = (ImageView) convertView.findViewById(R.id.imageView);
TextView tVId = (TextView) convertView.findViewById(R.id.textView3);
amountText = (TextView) convertView.findViewById( R.id.amountItem );
tVName.setText(name);
amountText.setText( String.valueOf( amount ) );
amountText.setTag(position);
Picasso.with(mContext).load(img).into(imgV); // tVBrand.setText(brand);
//tVId.setText(id);
//Buttons
Button addButton =(Button) convertView.findViewById(R.id.addValue);
Button subButton =(Button) convertView.findViewById(R.id.subValue);
addButton.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View view) {
getItem(position).incrementAmount();
//This gives the right position and the amount for all items
Log.d("ifIncreased", " " + getItem(position).getAmount());
Log.d("ifIncreased", position + "" );
TextView newText = (TextView) amountText.getTag(position);
newText.setText( String.valueOf( getItem(position).getAmount()));
}
} );
subButton.setOnClickListener( new View.OnClickListener() {
#Override
public void onClick(View view) {
if(getItem(position).getAmount() == 1)
{
//TODO remove from list;
}
else{
getItem(position).decrementAmount();
Log.d("ifIncreased", position + "" );
amountText.setText( String.valueOf( getItem(position).getAmount()) );
}
}
} );
return convertView;
}

So- since I am having the right values in the onClick functions, my question is, how can I change each TextView (the amount of that item) from the items in the full list?

Try this to update single value into adapter.. make public method and that method called into fragment or activity when you updated any value and refresh adapter.
/**
* this method used to update list item when broad cast received.
* #param percentage
* #param position
*/
public void updateProgress(double percentage, final int position) {
feedBackVoList.get(position).setPercentage(percentage);
notifyItemChanged(position);
}
after that updated value set into textview when you called notifyItemChanged(position) reset again that row or refresh that row.

how to get gettext of a text view in getview method?

I have a listview populating using cursor in which custom row exist. There are set of textviews in the row. I also have a image view in the row. I would like to set an image based on a value of the textview. My code is
public class DisplayCards extends Activity {
private Divyadesamdb dbHelper;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pasuram);
dbHelper = new Divyadesamdb(this);
dbHelper.open();
// Clean all data
dbHelper.deleteAllPasurams();
// Add some data
dbHelper.insertPasurams();
Intent intent = getIntent();
String category = intent.getStringExtra(MainActivity.EXTRA_CATEGORY);
String start = intent.getStringExtra(MainActivity.EXTRA_START);
String ending = intent.getStringExtra(MainActivity.EXTRA_ENDING);
// Generate ListView from SQLite Database
displayListView(category, start, ending);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
private void displayListView(String mcategory, String mstart, String mending) {
String category = mcategory;
String starting = mstart;
String ending = mending;
int rowsFound = 0;
Cursor cursor = dbHelper.fetchAllPasurams(category, starting, ending);
/*
* How many rows returned from the query
*/
rowsFound = cursor.getCount();
// the desired columns to be bound
String[] columns = new String[] {
Divyadesamdb.PASURAMS_COLUMN_PAASURAMNUMBER,
Divyadesamdb.PASURAMS_COLUMN_AAYIRAM,
Divyadesamdb.PASURAMS_COLUMN_AZHWAAR,
Divyadesamdb.PASURAMS_COLUMN_CATEGORY,
Divyadesamdb.PASURAMS_COLUMN_MANGALASASANAMON,
Divyadesamdb.PASURAMS_COLUMN_PAASURAM_EN_STR,
Divyadesamdb.PASURAMS_COLUMN_SUBCATEGORY,
Divyadesamdb.PASURAMS_COLUMN_TITLE,
Divyadesamdb.PASURAMS_COLUMN_TITLENUMBER };
// the XML defined views which the data will be bound to
int[] to = new int[] { R.id.tvPaasuramNumber, R.id.tvAayiram,
R.id.tvAzhwaar, R.id.tvCategory, R.id.tvMangalasasanamOn,
R.id.tvPaasuram, R.id.tvSubCategory, R.id.tvTitle,
R.id.tvtvTitleNumber };
// create the adapter using the cursor pointing to the desired data
// as well as the layout information
MyCursorAdapter dataAdapter = new MyCursorAdapter(this,
R.layout.paasuram_single_item, cursor, columns, to, 0);
ListView listView = (ListView) findViewById(R.id.listView1);
listView.setAdapter(dataAdapter);
}
// extend the SimpleCursorAdapter to create a custom class where we
// can override the getView to change the row colors
private class MyCursorAdapter extends SimpleCursorAdapter {
public MyCursorAdapter(Context context, int layout, Cursor c,
String[] from, int[] to, int flags) {
super(context, layout, c, from, to, flags);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// get reference to the row
View view = super.getView(position, convertView, parent);
// check for odd or even to set alternate colors to the row
// background
// want to get the value of this text view,
// but not getting handle.
LayoutInflater inflater = ((Activity) Context).getLayoutInflater();
TextView azhwaarView = (TextView) view.getTag(R.id.textViewAzhwaar);
String azhVal = azhwaarView.getText().toString();
if (position % 2 == 0) {
view.setBackgroundColor(Color.rgb(238, 233, 233));
} else {
view.setBackgroundColor(Color.rgb(255, 255, 255));
}
return view;
}
}
}
not sure how to get the handle of textview. Getting Null pointer exception. Any help is greatly appreciated.

Only two errors are their:
1).You are not inflating any view here:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
View view = inflater.inflate(R.layout.custom_inflator_layout,parent,false);
TextView azhwaarView = (TextView) view.getTag(R.id.textViewAzhwaar);
String azhVal = azhwaarView.getText().toString();
return view;
}
2).You are not seting any text to textview ,thats y when you trying to get the text
it gives null pointer.

In order to resolve the problem I have done the following:
created a table column with int datatype
got the R.drawable.xxx and stored the int to the database
retrieved the data and set to the image in the row level.
Thanks for all the help! Appreciate every help rendered. Big thanks once again.

I am trying to set up an OnItemClickListener so when the user clicks anywhere on the list item, a new Intent is started.
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//Populate list view with array objects
adapter = new HomeListItemAdapter(items, getActivity());
listView = getListView();
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Toast toast = Toast.makeText(listView.getContext(), "CLICKED", Toast.LENGTH_SHORT);
toast.show();
}
});
}
I am attempting this as shown above but can't seem to get the OnItemClickListener to work (just testing with Toast instead of Intent for now). Where am I going wrong?
Thanks
EDIT: Added custom list adapter code
public class HomeListItemAdapter extends BaseAdapter {
private List<HomeListItem> items;
private Context context;
private int numItems = 0;

Try extending ListFragment (instead of just a normal Fragment). Then you can override onListItemClicked:
public void onListItemClick(ListView l, View v, int pos, long id)
This gives you the list, view, position, and id, so you should be able to do whatever you need.

Could you try setting the HozizontalScrollView to not get focus with the XML attribute
android:focusable="false"

If you have a TextView inside the row then that will take focus when the row is clicked. This will mean that onListItemClick is not called. You either need to have an OnClickListener on the TextView or remove focus from the TextView.
See ListFragment OnListItemClick not being called

Try this sample project for costum ListFragment. It is a very good example with a costum ListFragment showing 2 types of views for phone and tablets.

Make Listview to Occupy Whole Screen

I have listview that i want to fill the whole screen,There are four items in listview. It leaves empty space below after four items are filled.You can see in the screenshot. It leaves the blank space. I want whole screen to be covered.
I would like to have like this:
Here is the source Code
MainActivity.java.
public class MainActivity extends Activity {
ListView resultPane;
List<Taskinfo> list;
CustomAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
resultPane = (ListView) findViewById(R.id.mylist);
list = new ArrayList<Taskinfo>();
Resources res = getResources(); // resource handle
Drawable drawable = res.getDrawable(R.drawable.browse_home);
list.add(new Taskinfo("Browse", drawable));
drawable = res.getDrawable(R.drawable.jewelry);
list.add(new Taskinfo("Whats New", drawable));
drawable = res.getDrawable(R.drawable.show);
list.add(new Taskinfo("Upcoming Show", drawable));
drawable = res.getDrawable(R.drawable.contact);
list.add(new Taskinfo("Contact Us", drawable));
adapter = new CustomAdapter(this, list);
resultPane.setAdapter(adapter);
}
}
CustomAdapter.java
public class CustomAdapter extends BaseAdapter {
private Context context;
private List<Taskinfo> list;
public CustomAdapter(Context context, List<Taskinfo> list) {
this.context = context;
this.list = list;
}
public View getView(int index, View view, final ViewGroup parent) {
if (view == null) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
view = inflater.inflate(R.layout.single_list_item, parent, false);
}
Taskinfo t = list.get(index);
RelativeLayout l = (RelativeLayout) view
.findViewById(R.id.testrelative);
l.setBackgroundDrawable(t.getImage());
TextView textView = (TextView) view.findViewById(R.id.title);
textView.setText(t.getName());
return view;
}
}
single_list_item.xml

Using ListView in such case is strange and unnecessary. Think about your constraints (like: what if items overflow?) and just use a proper layout manager. Like a vertical LinearLayout with the last item having a non-zero layout weight.
ListViews make sense only if you need an abstraction that generates list items on-the-fly.

You would want to set a background on the ListView. Currently your view should be going to the bottom, but the background of the ListView is transparent, so setting it white should achieve what you're asking.
<ListView ...
android:background="#android:color/white"
... />

if there are so few items, you can use the LinearLayout instead, and give weights for each of its items.
However, do note that android supports many devices and screens, so you might want to have a limitation of how small each row would be.
anyway, in case you wish to make each row the fitting height, you can check its size and then divide by the number of items.
in order to get the size of the listView , you can use this small snippet i've made .
