Why there is an error in setOnItemClickListener

I use fragment and I want to set listview in m fragment.I have error in this field.
I want to use ListView of Foldingcell, but I think I have an error in my adapter.
i can not find error.
any body can't help me?
what should I do?
this is my error:
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null object reference
at com.a700daneh.a700daneh.loanFragment.onCreateView(loanFragment.java:49)
this is my element for using in listView

this is my adapter called FoldingCellListAdapter
public class FoldingCellListAdapter extends ArrayAdapter<Item> {

ViewHolder viewHolder;
if (cell == null) {
viewHolder = new ViewHolder();
LayoutInflater vi = LayoutInflater.from(getContext());
cell = (FoldingCell) vi.inflate(R.layout.cell, parent, false);
// binding view parts to view holder
viewHolder.family1 = (TextView) cell.findViewById(R.id.family1);

cell.setTag(viewHolder);
} else {

if (unfoldedIndexes.contains(position)) {
cell.unfold(true);
} else {
cell.fold(true);
}

return cell;
}
// simple methods for register cell state changes
public void registerToggle(int position) {

else
registerUnfold(position);
}

}
}
this is my codes in loanFragment
public class loanFragment extends Fragment {
public loanFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.cell, container, false);
ListView lvlist = (ListView) view.findViewById(R.id.lvlist);
final ArrayList<Item> items = Item.getTestingList();
// create custom adapter that holds elements and their state (we need hold a id's of unfolded elements for reusable elements)
final FoldingCellListAdapter adapter = new FoldingCellListAdapter(getContext(), items);
// set elements to adapter
lvlist.setAdapter(adapter);
// set on click event listener to list view
lvlist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int pos, long l) {
// toggle clicked cell state
((FoldingCell) view).toggle(false);
// register in adapter that state for selected cell is toggled
adapter.registerToggle(pos);
}
});
return view;
}
}
I had a layout called cell_content_layout for foldingcell and another layout called cell_title_layout and include these layouts in one layout called cell.

It looks like your error is in the setAdapter not the onItemClickListener.
My guess is that ListView lvlist = (ListView) view.findViewById(R.id.lvlist); return null;
Check if "R.id.lvlist" is realy the id of your listView in the xml file.
Also, Check if "lvlist" is null after the findViewById line of code

Add item to RecyclerView from AlertDialog input

I'm currently having trouble with adding a second+ items to a RecyclerView after inputting data in an alertdialog box.
I can enter 1 set of data but when I try to add more, it doesn't do anything.
This is my Java file for the fragment i'm working with:
public class tab1Expenses extends Fragment {
List<ExRow> expenseList = new ArrayList();
RecyclerView recyclerView;
ExpensesAdapter mAdapter;
Button btnEx;
EditText txtExName;
EditText txtExAmount;
public void expenseData() {
String Na = txtExName.getText().toString();
String Am = txtExAmount.getText().toString();
ExRow exs = new ExRow(Na, Am);
expenseList.add(exs);
mAdapter.notifyDataSetChanged();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.tab1expense, container, false);
btnEx = (Button) rootView.findViewById(R.id.btnEx);
recyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_view);
mAdapter = new ExpensesAdapter(expenseList);
final RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.setAdapter(mAdapter);
btnEx.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View view = LayoutInflater.from(tab1Expenses.this.getActivity())
.inflate(R.layout.add_ex, null);
txtExName = (EditText) view.findViewById(R.id.exName);
txtExAmount = (EditText) view.findViewById(R.id.exAmount);
AlertDialog.Builder add = new AlertDialog.Builder(tab1Expenses.this.getActivity());
add.setCancelable(true)
.setTitle("Enter Expense:")
.setView(view)
.setPositiveButton("Add", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
expenseData();
}
});
Dialog dialog = add.create();
dialog.show();
}
});
return rootView;
}
}
And the Java file for the adapter:
public class ExpensesAdapter extends RecyclerView.Adapter<ExpensesAdapter.MyViewHolder> {
private List<ExRow> expenseList;
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title, amount;
public MyViewHolder(View view) {
super(view);
title = (TextView) view.findViewById(R.id.name);
amount = (TextView) view.findViewById(R.id.amount);
}
}
public ExpensesAdapter(List<ExRow> expenseList) {
this.expenseList = expenseList;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.expense_list, parent, false);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
ExRow expense = expenseList.get(position);
holder.title.setText(expense.getTitle());
holder.amount.setText(expense.getAmount());
}
#Override
public int getItemCount() {
return expenseList.size();
}
}
The XML to format the recyclerview list items:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/name"
android:textColor="#color/title"
android:textSize="16dp"
android:textStyle="bold"
android:layout_alignParentLeft="true"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/amount"
android:textColor="#000000"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"
android:layout_height="wrap_content" />
</RelativeLayout>
And this is the XML for the fragment:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.ojemz.expensetracker.tab1Expenses"
android:background="#android:color/darker_gray">
<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/btnEx"
android:layout_alignParentBottom="true"

android:textAppearance="#style/TextAppearance.AppCompat.Widget.Switch"
android:background="#android:color/black"
android:textColor="#android:color/holo_green_light"
android:textColorLink="#android:color/holo_green_light" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="450dp"
android:layout_alignParentBottom="true"
android:layout_alignParentStart="true"
android:layout_marginBottom="17dp">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="450dp"
android:scrollbars="vertical"
android:keepScreenOn="true"
android:isScrollContainer="true" />
</android.support.v4.widget.NestedScrollView>
</LinearLayout>
This is what I currently see AFTER adding a 2nd input

You can't do so:
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentStart="true"
android:layout_marginBottom="17dp">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical" />
</ScrollView>
Your RecyclerView has 0 height now. You need to add a some fixed height to it and set a scroll behaviour. Or you can use NestedScrollView or write LayoutManager with the full height expansion.
See this thread for details.
ADDED
Use this XML instead of your but I wrote it without IDE so it can contain some errors.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.ojemz.expensetracker.tab1Expenses"
android:background="#android:color/darker_gray">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:keepScreenOn="true" />
<Button
android:text="Add Expense"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/btnEx"
android:layout_gravity="bottom|center_horizontal"
android:textAppearance="#style/TextAppearance.AppCompat.Widget.Switch"
android:background="#android:color/black"
android:textColor="#android:color/holo_green_light"
android:textColorLink="#android:color/holo_green_light" />
</FrameLayout>

I solved my problem. It was to do with the height of the relative layout for the recycler items. It was on match parent, i switched to wrap content and it now displays the inputs on the screen

btnLike.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
countLike ++;
Log.e("LIKE_CONT", " is " + countLike);
btnLike.setImageDrawable(context.getResources().getDrawable(R.drawable.ic_heart_red));
Toast.makeText(context, "Clicked at index ", Toast.LENGTH_SHORT).show();
}
});
return v;
}
}
I want to add click listener on btnLike and want to change the image resource in method
btnLike.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
countLike ++;
Log.e("LIKE_CONT", " is " + countLike);
btnLike.setImageDrawable(context.getResources().getDrawable(R.drawable.ic_heart_red));
Toast.makeText(context, "Clicked at index ", Toast.LENGTH_SHORT).show();
}
});
but result is
means the image resource of btnLike is not changed in current card but as I shuffle cards and see on the other card the image resource of btnLike is changed any suggestions how to see that bit of code so that it can work properly...

Images does not scroll in ViewPager in Android

I'm implementing View-pager in List-view as row item .When run the application my images is not scrolling one by one in view pager. What is the wrong in my code. Can someone suggest me how to make it work or scrolling smoothly images in view pager.
Here is my code
public class Demo_Display extends Activity {
private String str[] = {"weklfjo","??2","??3"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView listView = (ListView)findViewById(R.id.listview);
MyListAdapter adapter = new MyListAdapter(this,R.layout.row,str);
listView.setAdapter(adapter);
}
class MyListAdapter extends ArrayAdapter<String> {
private LayoutInflater inflater = null;
private static final float BUTTON_WIDTH_DP = 70f;
private int margin;
public MyListAdapter(Context context, int resource,String[] items) {
super(context, resource,items);
inflater = LayoutInflater.from(context);
float density = getContext().getResources().getDisplayMetrics().density;
int buttonWidthPX = (int) (BUTTON_WIDTH_DP * density + 0.5f);
WindowManager wm = (WindowManager)getContext().getSystemService(getContext().WINDOW_SERVICE);
Display dp = wm.getDefaultDisplay();
margin = dp.getWidth() - buttonWidthPX;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView == null){
convertView = inflater.inflate(R.layout.row,null);
}
ViewPager viewPager = (ViewPager)convertView.findViewById(R.id.Image_ViewPagers);
viewPager.setPageMargin(-margin);
// MyPagerAdapter adapter = new MyPagerAdapter(getContext(),getItem(position));
MyPagerAdapter adapter = new MyPagerAdapter(getContext());
viewPager.setAdapter(adapter);
return convertView;
}
}
class MyPagerAdapter extends PagerAdapter {
Context mContent;
LayoutInflater mLayoutInflater;
private int[] GalImages = new int[] {
R.drawable.flower1,
R.drawable.flower1
};
public MyPagerAdapter(Context context) {
super();
mContent = context;
mLayoutInflater = (LayoutInflater) mContent.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override

{

int padding = mContent.getResources().getDimensionPixelSize(R.dimen.abc_button_padding_horizontal_material);
imageView.setPadding(padding, padding, padding, padding);
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setImageResource(GalImages[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((View) object);
}
#Override
public int getCount() {
// return PAGE_NUM;
return GalImages.length;
}
#Override
public boolean isViewFromObject(View view, Object obj) {
//return view.equals(obj);
return view == ((ImageView) obj);
}

setOnClickListener not firing with custom adapter and custom ListView

I've been spending a few hours on a problem and I still can't figure it out. The setOnClickListener in HotelOverviewFragment is not firing when I click an item in my ListView. However, the setOnClickListener does work from my custom adapter (NowArrayAdapter).
My question is: why the setOnClickListener not working in HotelOverviewFragment (Class where the ListView is shown)?
Here's a list of what I've tried:
Setting android:focusable="false", android:focusableInTouchMode="false", android:descendantFocusability="blocksDescendants" in the hotel_row_layout.xml and fragment_hotel_overview.xml.
Setting android:clickable on true and false. Both didn't work.
Changing from BaseAdapter implementation to arrayAdapter.
I tried different listeners in HotelOverviewFragment: setOnClickListener, setOnItemClickListener, setOnItemSelectedListener and setOnTouchListener. Unfortunately, none of those worked for me.
Here's my code:
Custom adapter
public class NowArrayAdapter extends ArrayAdapter<String> {
private Context context;
private ArrayList<String> values;
private Typeface typeface;
private static Hashtable fontCache = new Hashtable();
private LayoutInflater inflater;
private TextView item;
public NowArrayAdapter(Context context, ArrayList<String> commandsList) {
super(context, R.layout.hotel_row_layout, commandsList);
this.context = context;
values = new ArrayList<String>();
values.addAll(commandsList);
typeface = getTypeface(this.context, "fonts/Roboto-Light.ttf");
inflater = LayoutInflater.from(this.context);
}
static Typeface getTypeface(Context context, String font) {
Typeface typeface = (Typeface)fontCache.get(font);
if (typeface == null) {
typeface = Typeface.createFromAsset(context.getAssets(), font);
fontCache.put(font, typeface);
}
return typeface;
}
public View getView(int position, View convertView, ViewGroup parent) {
String myText = getItem(position);
if(convertView == null) {
convertView = inflater.inflate(R.layout.hotel_row_layout, parent, false);
item = (TextView) convertView.findViewById(R.id.maps_button);
item.setTypeface(typeface);
convertView.setTag(item);
} else {
item = (TextView) convertView.getTag();
}
item.setText(myText);
//myListItem.descText.setTextSize(14);
convertView.setOnClickListener(new View.OnClickListener() {
// WORKS!
#Override
public void onClick(View view) {
Log.d("click", "Don't look at me!");
}
});
return convertView;
}
}
Fragment
public class HotelOverviewFragment extends Fragment {
private static Hashtable fontCache = new Hashtable();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_hotel_overview, container, false);
ListView list = (ListView) v.findViewById(android.R.id.list);
// Set up listview and buttons
setUp(v, list);
// Inflate the layout for this fragment
return v;
}
static Typeface getTypeface(Context context, String font) {
Typeface typeface = (Typeface)fontCache.get(font);
if (typeface == null) {
typeface = Typeface.createFromAsset(context.getAssets(), font);
fontCache.put(font, typeface);
}
return typeface;
}
public void setUp(View v, ListView l){
TextView address = (TextView) v.findViewById(R.id.content);
TextView header = (TextView) v.findViewById(R.id.header);
TextView hotelName = (TextView) v.findViewById(R.id.hotelName);
Typeface typeface = getTypeface(getActivity(), "fonts/Roboto-Light.ttf");
address.setText("some street \nZipCode, City \nCountry \nEmail \nphoneNumber");
address.setTypeface(typeface);
header.setText("Hotel info");
header.setTypeface(typeface);
header.setTextSize(20);
hotelName.setText("Hotel name");
hotelName.setTypeface(typeface);
// Set up button
ArrayList<String> n = new ArrayList<String>();
n.add(0, "More info");
// Show button
NowArrayAdapter adapter = new NowArrayAdapter(getActivity(), n);
l.setAdapter(adapter);
// THIS IS THE STUFF I'VE BEEN TRYING
try {
l.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("click", "Success");
}
});
l.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.d("click", "Success");
}
});
l.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.d("click", "Success");
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
l.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
Log.d("click", "Success");
return false;
}
});
}catch (Exception e){
Log.d("click", e + "");
}
}
}

Thanks in advance.

Thanks to Daniel Nugent's suggestion I got it working. Removing the convertView.setOnClickListener() is part of the answer. I think it was blocking the other listeners in the HotelOverviewFragment.
My next mistake was that I used setOnClickListener on a ListView for testing.
setOnClickListener should be used for buttons not ListViews.
So after removing setOnClickListener all the other listeners started working.
Thanks for your time.
