My listview in import_fragment.xml, when i open import_fragment.xml in app its appear only Contact Name and Phone and Email and Address which is added in import_fragment.xml and not the new contact information which in database added by user.
You have to setAdapter in onCreateView. Currently you are populating the list in onCreateContextMenu. Moreover, after setting the adapter, you have to call notifyDataSetChanged() as well
Try this way, i have tried this in my machine and it show me listview properly , i have done with weightSum so it will be applicable for all devices , just change your xml file with below one
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="4">
<ImageView
android:id="#+id/ivContactImage"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3"
android:orientation="vertical">
<TextView
android:id="#+id/contactName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:text="Contact Name"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/phoneNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:layout_marginTop="5dp"
android:text="Phone" />
<TextView
android:id="#+id/emailAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:text="Email" />
<TextView
android:id="#+id/cAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:text="Address" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left|center_vertical"
android:text="My Contacts"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
</LinearLayout>
<ListView
android:id="#+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center" />
Change both of your LinearLayout's height to
android:layout_height="fill_parent"
Your listView is actually "there", it's just that the container (layout) of the listView isn't big enough to fit it.
EDIT:
You are defining two different list of Contacts there! Both activity and adapter class are referring to two different Contacts. Remove the one inside the onCreateView function.
final List<import_fragment.Contact> Contacts = new ArrayList<import_fragment.Contact>();

I couldnt able to display my data from firebase to my listview in android application. Rather it only shows one data.
Heres the current data of my database:
Database
And this is my java:
public class scheduleList extends ArrayAdapter<Schedule> {
private Activity context;
private List<Schedule> scheduleList;
public scheduleList(Activity context, List<Schedule> scheduleList){
super(context, R.layout.listlayout, scheduleList);
this.context=context;
this.scheduleList=scheduleList;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listviewItem = inflater.inflate(R.layout.listlayout, null, true);
TextView textViewName = (TextView) listviewItem.findViewById(R.id.textViewName);
TextView textViewSchedule = (TextView) listviewItem.findViewById(R.id.textViewSchedule);
Schedule schedule = scheduleList.get(position);
textViewName.setText(schedule.getAppointer());
textViewSchedule.setText(schedule.getAppointment_schedule());
return listviewItem;
}}
My java file:
public class Appointment extends AppCompatActivity {
CalendarView calendarView;
TextView myDate;
private Button btn1;
ListView listViewSchedule;
List<Schedule> scheduleList;
DatabaseReference databaseAppointments;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_appointment);
databaseAppointments = FirebaseDatabase.getInstance().getReference("appointment");
calendarView = (CalendarView) findViewById(R.id.calendarView);
myDate = (TextView) findViewById(R.id.myDate);
listViewSchedule=(ListView) findViewById(R.id.listViewSchedule);
scheduleList = new ArrayList<>();
btn1 = (Button) findViewById(R.id.appt);
btn1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent myIntent = new Intent(Appointment.this, appointments2.class);
Appointment.this.startActivity(myIntent);
}
});
calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
#Override
public void onSelectedDayChange(#NonNull CalendarView view, int i, int i1, int i2) {
String date = (i1 + 1) + "/" + i2 + "/" + i;
myDate.setText(date);
}
});
}
#Override
protected void onStart() {
super.onStart();
databaseAppointments.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
scheduleList.clear();
for(DataSnapshot scheduleSnapshot: dataSnapshot.getChildren()){
Schedule schedule = scheduleSnapshot.getValue(Schedule.class);
scheduleList.add(schedule);
}
scheduleList adapter = new scheduleList(Appointment.this, scheduleList);
listViewSchedule.setAdapter(adapter);
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}}

Im guessing that the scrollview layout affects the listview but im not sure. Also the listview display whatevers the first on the list.
use FirebaseRecyclerAdapter. search example of how to use FirebaseRecylerAdapter with example.
Here is my code so far based on various answers to related questions on SO.
In my Activity
GridView gv = (GridView) findViewById(R.id.gridView1);
MyCustomAdapter mAdapter = new MyCustomAdapter();
mAdapter.addItem("Action1");
mAdapter.addItem("Action2");
mAdapter.addItem("Action3");
gv.setAdapter(mAdapter);
My Adapter
private class MyCustomAdapter extends BaseAdapter {
private ArrayList<String> mData = new ArrayList<String>();
private LayoutInflater mInflater;
public MyCustomAdapter() {
mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void addItem(final String item) {
mData.add(item);
notifyDataSetChanged();
}
#Override
public int getCount() {
return mData.size();
}
#Override
public String getItem(int position) {
return mData.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
NumericViewHolder holder = new NumericViewHolder();
if (convertView == null) {
convertView = mInflater.inflate(R.layout.horizontalnumberpicker, null);
holder.textView = (TextView)convertView.findViewById(R.id.txtNPTitle);
holder.minus = (Button)convertView.findViewById(R.id.btnMinus);
holder.plus = (Button)convertView.findViewById(R.id.btnPlus);
holder.value = (TextView)convertView.findViewById(R.id.txtNPValue);
holder.minus.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
TextView tv = (TextView) v.findViewById(R.id.txtNPValue);
int value = Integer.parseInt(tv.getText().toString());
Toast.makeText(getApplicationContext(), Integer.toString(value), Toast.LENGTH_SHORT).show();
if (value > 0) {
value = value - 1;
tv.setText(Integer.toString(value));
}
}
});
holder.plus.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
TextView tv = (TextView) v.findViewById(R.id.txtNPValue);
int value = Integer.parseInt(tv.getText().toString()); <--Error is here
Toast.makeText(getApplicationContext(), Integer.toString(value), Toast.LENGTH_SHORT).show();
value = value + 1;
tv.setText(Integer.toString(value));
}
});
convertView.setTag(holder);
} else {
holder = (NumericViewHolder)convertView.getTag();
}
holder.textView.setText(mData.get(position));
return convertView;
}
}

The requirement is that when I press the plus button, I need to increment the value in the corresponding txtNPValue. Similarly with the minus button, I need to decrement the value in the txtNPValue.
The error is
01-31 22:40:10.854: E/AndroidRuntime(32198): java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.CharSequence android.widget.TextView.getText()' on a null object reference
Also I do not know if this is the right way to program such a requirement and would like some pointers.
TextView tv = (TextView) v.findViewById(R.id.txtNPValue);
this will return null pointer exception, as the view that u r getting is of the button or the clicked item..
Use this :-
RelativeLayout rlLayout = (RelativeLayout) v.getParent();
TextView tv = (TextView) rlLayout.findViewById(R.id.txtNPValue);
please remove:
TextView tv = (TextView) v.findViewById(R.id.txtNPValue);
from onClick to resolve nullpointerException
I have created a list view with plus and minus buttons on each row but the value only changes on the top row also i need a way so that when i click submit order it will reference the type of coffee and say what the quantity is that that was ordered.

i dont know how is your on click listener code but i am providing some example for that-
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.my_custom_list_layout, null);
}
//Handle TextView and display string from your list
TextView listItemText = (TextView)view.findViewById(R.id.list_item_string);
listItemText.setText(list.get(position));
//Handle buttons and add onClickListeners
Button deleteBtn = (Button)view.findViewById(R.id.delete_btn);
Button addBtn = (Button)view.findViewById(R.id.add_btn);
deleteBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
//do something
list.remove(position); //or some other task
notifyDataSetChanged();
}
});
addBtn.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
//do something
notifyDataSetChanged();
}
});
return view;
}
}
I'm trying to click on row in list view but my code only works when i pressed between two rows
you can see this :
http://www.screencast.com/t/2vei8yOQh
note in rep.xml i using table layout and inside it rowTable
i uses this code :
public class LastDaysActivity extends ListActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_last_days);
final Button newFourm = (Button) findViewById(R.id.button1);
LastDaysAdapter adapter = new LastDaysAdapter(this, getDates(),
getApplicationContext(), getBusID());
setListAdapter(adapter);
newFourm.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {

edit xml :

I am trying to add a custom header that isnt clickable but will have a checkbox that will "check all" checkboxes under it.
This is my List Fragment
public class AssesmentListFragment extends ListFragment {
private static String BUNDLE_KEY_APPLICATION = "LIST_ITEM";
FastAssesmentListAdapter adapter;
View listHeader;
public AssesmentListFragment() {}
public AssesmentListFragment(Data[] data) {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Data[] assestments = {new Data("Assesment ID","Name", "Date"), new Data("123456", "Assestment 2", "9/12/12"),
new Data("345672", "Assesment 3", "9/13/12"), new Data("566893", "Assesment 4", "9/14/12")};
//This is the part that makes the app crash
View header = getActivity().getLayoutInflater().inflate(R.layout.list_adapter_assesments, null);
ListView listView = getListView();
listView.addHeaderView(header);
adapter = new FastAssesmentListAdapter(getActivity(), assestments);
setListAdapter(adapter);
updateList(assestments);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
private void updateList(Data[] assestments) {
// NOTE: addAll is not being used to support pre-honeycomb devices
synchronized(adapter) {
adapter.clear();
adapter.addAll(assestments);
adapter.notifyDataSetChanged();
}
}
#Override
public void onListItemClick(ListView parentView, View selectedItemView, int position, long id) {
String model = (String) parentView.getItemAtPosition(position);
((FacilityActivity) getActivity()).onItemSelected(model);
}
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
//outState.putInt("curChoice", mCurCheckPosition);
}
}
This is the layout I am trying to use for header
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="25dp"
android:paddingRight="10dp"
android:orientation="horizontal">
<TextView android:id="#+id/adapter_header_textview_column1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="4"
android:textColor="#color/defaultTextColor"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="28sp"
android:text="Assesment ID" />
<TextView android:id="#+id/adapter_header_textview_column2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="4"
android:textColor="#color/defaultTextColor"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="28sp"
android:text="Name" />
<TextView android:id="#+id/adapter_header_textview_column3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:textColor="#color/defaultTextColor"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="28sp"
android:text="Date"/>
<CheckBox
android:id="#+id/header_check_box"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:color="#color/defaultTextColor"
android:layout_weight=".5"
android:gravity="center" />
</LinearLayout>
<View
android:layout_width="fill_parent"
android:layout_height="5dp"
android:background="#color/BPGreenColor" />
<ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
Then this is the array adapter I am using:
public class FastAssesmentListAdapter extends ArrayAdapter<Data> {
private static int LAYOUT_ID = R.layout.list_adapter_with_checkbox_three_column;
private final Data[] assesments;
private final Context context;
LinearLayout listHeader;
static class ViewHolder {
protected TextView column1;
protected TextView column2;
protected TextView column3;
protected CheckBox checkbox;
}
public FastAssesmentListAdapter(Context context, Data[] assesments) {
super(context, LAYOUT_ID, assesments);
this.context = context;
this.assesments = assesments;
}
//ListFragment and array adapter will automatically call this over and over to auto populate the list
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final Data item = getItem(position);
// Formulate row view (create if it does not exist yet)
View view = convertView;
if(view == null) {
LayoutInflater inflater = ((Activity) getContext()).getLayoutInflater();
view = inflater.inflate(LAYOUT_ID, null);
final ViewHolder viewHolder = new ViewHolder();
viewHolder.column1 = (TextView) view.findViewById(R.id.adapter_textview_column1);
viewHolder.column2 = (TextView) view.findViewById(R.id.adapter_textview_column2);
viewHolder.column3 = (TextView) view.findViewById(R.id.adapter_textview_column3);
viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check_box);
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), "Clicked",
Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getContext(), FacilityActivity.class);
getContext().startActivity(intent);
}
});
if(viewHolder.checkbox != null) {
viewHolder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if(isChecked) {
item.setSelected(isChecked);
Toast.makeText(getContext(), "Checked",
Toast.LENGTH_SHORT).show();
}
}
});
}
view.setTag(viewHolder);
viewHolder.checkbox.setTag(position);
}
ViewHolder viewHolder = (ViewHolder) view.getTag();
viewHolder.checkbox.setTag(position);
viewHolder.column1.setText(item.getColumn1());
viewHolder.column2.setText(item.getColumn2());
viewHolder.column3.setText(item.getColumn3());
viewHolder.checkbox.setChecked(item.isSelected());
return view;
}
}
on a side note, the onlistitemclicked in the fragment doesnt work, i have to set a listener in the adapter and then it works. any ideas on that? but mainly I need to figure out how to use a custom header and custom rows in the list view. Here is the layout for the rows
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="25dp"
android:paddingRight="10dp"
android:orientation="horizontal">
<TextView android:id="#+id/adapter_textview_column1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="4"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="25sp" />
<TextView android:id="#+id/adapter_textview_column2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="4"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="25sp" />
<TextView android:id="#+id/adapter_textview_column3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textSize="25sp" />
<CheckBox
android:id="#+id/check_box"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight=".5"
android:gravity="center" />
</LinearLayout>
