Hello dear Stackoverflow community. I'm coming to you for help, as you can guess.
I have a ListView for which each row should follow this layout, row_layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:background="#color/brownish">
<ImageView
android:id="#+id/passport_flag"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true"
android:layout_marginEnd="6dp"
android:contentDescription="#string/country_flag" />
<TextView
android:id="#+id/exp_date"
android:layout_width="wrap_content"
android:layout_height="16dip"
android:ellipsize="marquee"
android:singleLine="true"
android:text="#string/exp_date"
android:textSize="12sp"
android:textColor="#color/white"
android:layout_alignParentBottom="true"
android:layout_alignParentStart="true"
android:layout_marginStart="6dp" />
<TextView
android:id="#+id/birth_date"
android:layout_width="wrap_content"
android:layout_height="16dip"
android:ellipsize="marquee"
android:singleLine="true"
android:text="#string/birth_date"
android:textSize="12sp"
android:textColor="#color/white"
android:layout_above="#+id/exp_date"
android:layout_alignStart="#+id/exp_date" />
<TextView
android:id="#+id/document_number"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:singleLine="true"
android:layout_alignStart="#+id/exp_date"
android:layout_above="#id/birth_date"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:layout_alignWithParentIfMissing="true"
android:text="#string/document_number"
android:textSize="16sp"
android:textColor="#color/white" />
</RelativeLayout>
I implemented a custom ArrayAdapter, for which here is the code:
public class CustomArrayAdapter extends ArrayAdapter<EPassport> {
public static final String TAG = "CustomArrayAdapter";
private final String DOCUMENT_NUMBER = "Passport number: ";
private final String DATE_OF_BIRTH = "Date of birth: ";
private final String DATE_OF_EXPIRY = "Date of expiry: ";
private Context context;
private List<EPassport> ePassportsList;
private static class ViewHolder {
public TextView documentNumber;
public TextView birthDate;
public TextView expDate;
public ImageView flag;
}
public CustomArrayAdapter(Context context, List<EPassport> ePassportsList) {
super(context, R.layout.row_layout, ePassportsList);
this.context = context;
this.ePassportsList = ePassportsList;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
if (rowView == null) {
LayoutInflater inflater =
(LayoutInflater) context
.getApplicationContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.row_layout, null);
ViewHolder viewHolder = new ViewHolder();
viewHolder.documentNumber = (TextView) rowView.findViewById(R.id.document_number);
viewHolder.birthDate = (TextView) rowView.findViewById(R.id.birth_date);
viewHolder.expDate = (TextView) rowView.findViewById(R.id.exp_date);
viewHolder.flag = (ImageView) rowView.findViewById(R.id.passport_flag);
rowView.setTag(viewHolder);
}
ViewHolder holder = (ViewHolder) rowView.getTag();
EPassport rowPassport = this.ePassportsList.get(position);
holder.expDate.setText(DATE_OF_EXPIRY + rowPassport.getDateOfExpiry());
holder.birthDate.setText(DATE_OF_BIRTH + rowPassport.getDateOfBirth());
holder.documentNumber.setText(DOCUMENT_NUMBER + rowPassport.getDocumentNumber());
if (rowPassport.getCountryCode() != null) {
String alpha2CountryCode = null;
try {
alpha2CountryCode = ISO3166Database.getAlpha2Code(rowPassport.getCountryCode());
} catch (IllegalCountryCodeException e) {
Log.e(TAG, e.getLocalizedMessage());
}
holder.flag.setImageResource(
getContext()
.getResources()
.getIdentifier(alpha2CountryCode, "drawable", getContext().getPackageName()));
}
return rowView;
}
}
I work with Android Studio 1.4 and the 'Design' tab of my row_layout.xml looks exactly how I want it to be.
When I run the application however, of the three text fields only one shows up on the screen.
I can't figure out the why. If anyone would like to give me a hand with this one, it would be greatly appreciated.

Try to use this as row:

Just change your data and color.

I am having a problem to set a "No results" message when getCount() returns 0.
I have a custom layout for the listview, and I simply want to get a "No Results" textview when there is no data on the listview.
Any idea how to achieve this?
I saw something with a empty id, but that needs to be on a listview, since this is a custom layout, it doesn't have that "tag".
Custom Adapter Code:
public class ListScheduleAdapter extends BaseAdapter {
Context context;
protected List<Schedule> listSchedules;
LayoutInflater inflater;
public ListScheduleAdapter(Context context, List<Schedule> listSchedules) {
this.listSchedules = listSchedules;
this.inflater = LayoutInflater.from(context);
this.context = context;
}
public int getCount() {
return listSchedules.size();
}
public Schedule getItem(int position) {
return listSchedules.get(position);
}
public long getItemId(int position) {
return listSchedules.get(position).getCod_Horario();
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = this.inflater.inflate(R.layout.layout_list_item,
parent, false);
holder.txtTeacher = (TextView) convertView
.findViewById(R.id.txt_teacher);
holder.txtDayofWeek = (TextView) convertView
.findViewById(R.id.txt_dayofweek);
holder.txtSubject = (TextView) convertView
.findViewById(R.id.txt_subject);
holder.txtTime = (TextView) convertView
.findViewById(R.id.txt_time);
holder.txtRoom = (TextView) convertView
.findViewById(R.id.txt_room);
holder.txtClass = (TextView) convertView
.findViewById(R.id.txt_class);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Schedule sche = listSchedules.get(position);
String fullTeacher = sche.getProfessor();
String[] names = fullTeacher.split(" ");
holder.txtTeacher.setText(names[0] + " " + names[names.length-1]);
holder.txtDayofWeek.setText(sche.getDia_Semana());
holder.txtSubject.setText(sche.getDisciplina());
holder.txtTime.setText(sche.getT_Entrada() + "h-" + sche.getT_Saida()+"h");
holder.txtRoom.setText(sche.getSala());
holder.txtClass.setText(sche.getTurma());
return convertView;
}
private class ViewHolder {
TextView txtTeacher;
TextView txtDayofWeek;
TextView txtSubject;
TextView txtTime;
TextView txtRoom;
TextView txtClass;
}
}

to the same layout where you declared your ListView (wrap both in a FrameLayout)
on the ListView's instance call
listView.setEmptyView(findViewById(R.id.empty));
when the adapter is empty, you will see the TextView apper
add TextView to your listview layout and setVisibility of it to GONE and check the adapter:
if(adapter==null){
listView.setVisiblity(View.GONE);
tvEmpty.setVisiblity(View.VISIBLE);
}
hope this will help.
I have a list that when you click on the row on the right side the layout with the icon is changed by other. This makes it well but when I scrolling in the list, I notice there are rows with the same icon without do click. Also, if I scroll quickly these same icons are lost and are built differently. I think it's on the reuse of cells but I can not find the solution. What I want is that the image stays active only in the row where clicka.
Thanks!!

You need to follow below Idea
1) this line of code mConverView = converView; doesn't makes sense. directly use converView(View from getView param). Remove mConvertView from the adapter.
2) Add some mechanism which can tell you which row is clicked and save that variable.
Example:- Have an boolean Array of size Rows.size . and set them in onClick.
Boolean[] array = new Boolean[getSize()];
in onClick that you already have in your getview set this.
public void onClick(View v) {
array[position] = !array[position];
viewHolder.lytUndo.setVisibility(View.VISIBLE);
//You do not need to call notifyDatasetChange.
3) in getView(), when you are setting data in to row items/or just before onClick. have a check like below.
if(array[position])// this will tell you if you need to show or hid lytUndo thing
viewHolder.lytUndo.setVisibility(View.VISIBLE); // Show it
else
viewHolder.lytUndo.setVisibility(View.GONE); // hide it or do whatever you want
You might need to set some params as final
I have written this as simple as possible, comment back with your result.
Above is the main screen of my app with a custom adapter for listview. How do I put a different icon for each row in the listview? I tried putting an ImageView in the xml but it overwrites my whole screen only showing an icon.

Your list.xml should be something similar to this (taken from one my files)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:gravity="center_vertical" android:orientation="horizontal"
android:background="#drawable/xml_pressed_bg" android:clickable="true" android:layout_width="fill_parent"

android:src="#drawable/sample_dj" />
<TextView android:textSize="14.0sp" android:textColor="#ff666666" android:id="#+id/txtName"

android:singleLine="true" android:shadowColor="#99ffffff" style="#style/TextShadowLight"
android:text="Hello" android:paddingLeft="10dip"/>
</LinearLayout>
Every row item has an image (imgThumb). This needs to be changed or set to a static image, depending on your needs. This is done in the adapters' getView() method.
imgThumb.setImageResource(R.drawable.my_image);
Private TypedArray img;
img=getResource.obtainTypedArray(R.array.imgIcon)
if (sa[position].startsWith("Air pressure")) {
rowView.setBackgroundResource(R.color.skyblue) ;
holder.image.setImageResource(img.gerResourceId[0]);
}else if (sa[position].startsWith("Air Condition")) {
holder.image.setImageResource(img.gerResourceId[1]);
}
I have a listview with a custom adapter (tile) design. Everything should work fine but the thing is that the til (listview item background) stretches too much despite me giving layout_height a fixed value. Here's the code:
This is the xml for the custom tile. Notice the 85dp fixed height. The background drawable should NOT stretch beyond this hight?

android:layout_height="85dp"
android:background="#drawable/tile_job" >
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="9dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="13dp"
android:text="Title" />
<TextView
android:id="#+id/pickup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginTop="38dp"
android:layout_alignLeft="#+id/title"
android:textSize="11dp"
android:text="Pickup Address" />
<TextView
android:id="#+id/destination"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/pickup"
android:layout_below="#+id/pickup"
android:layout_marginTop="6dp"

What is causing the tile to overstretch vertically?
===========
EDIT
Here is the requested code:
Inflation of the layout:
public class JobAdapter extends BaseAdapter
{
private ArrayList<Job> bookingArrayList;
private LayoutInflater mInflater;
public JobAdapter(Context context, ArrayList<Job> results)
{
bookingArrayList = results;
mInflater = LayoutInflater.from(context);
}
#Override
public int getCount()
{
return bookingArrayList.size();
}
#Override
public Object getItem(int arg0)
{
return bookingArrayList.get(arg0);
}
#Override
public long getItemId(int position)
{
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder;
if (convertView == null)
{
convertView = mInflater.inflate(R.layout.tile_job, null);
holder = new ViewHolder();
holder.date = (TextView) convertView.findViewById(R.id.date);
holder.time = (TextView) convertView.findViewById(R.id.time);
holder.pickup = (TextView) convertView.findViewById(R.id.pickup);
holder.destination = (TextView) convertView.findViewById(R.id.destination);
holder.title = (TextView) convertView.findViewById(R.id.title);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.date.setText(bookingArrayList.get(position).getDate());
holder.time.setText(bookingArrayList.get(position).getTime());
holder.pickup.setText(bookingArrayList.get(position).getPickup());
holder.destination.setText(bookingArrayList.get(position).getDestination());
holder.title.setText(bookingArrayList.get(position).getTitle());
return convertView;
}
static class ViewHolder
{
TextView date;
TextView time;
TextView pickup;
TextView destination;
TextView title;
}
}
Your creating you row with following:
convertView = mInflater.inflate(R.layout.tile_job, null);
Now try this:
convertView = mInflater.inflate(R.layout.tile_job, parent, false);
If you don't attach the parent layout the layout parameters from xml will be ignored. You set false as you don't attach the view to the root right away (this happens automatically when the view is returned). You can read more about this issue here.
I have been reading about multicolumn listviews today. They seem to be what I need, but can't info info about how to populate them not using a hash map. All examples I have seen use a hash map to build the listview data adapter but this is too heavy when lot of data is implied. Is there anyway to populate a list view without a hash list?
All examples I have seen use something like this:

Yes it is possible. please Check out the code.
public class List_view_ArrayAdapter extends ArrayAdapter<String> {
private Context context;
private String[] name;
private String[] address;
private String[] rating;
private TextView nameTextView;
private TextView addressTextView;
private ImageView lisiconImageView;
private AppManagers appManagers;
public List_view_ArrayAdapter(Context context, String[] name,
String[] address, String[] rating) {
super(context, R.layout.list_layout, name);
this.context = context;
this.name = name;
this.address = address;
this.rating = rating;
appManagers = new AppManagers();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_layout, parent, false);
nameTextView = (TextView) rowView.findViewById(R.id.nameTextView);
addressTextView = (TextView) rowView.findViewById(R.id.addressTextView);
lisiconImageView = (ImageView) rowView
.findViewById(R.id.listiconImageView);
nameTextView.setText(name[position]);
addressTextView.setText(address[position]);
lisiconImageView.setImageDrawable(appManagers
.ImageOperations(rating[position]));
// imageView.setImageResource(imageid[position]);
return rowView;
}
}
Here is list_layout for this line "R.layout.list_layout"
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"

</LinearLayout>
Finaly you call it from your main Activity.
new List_view_ArrayAdapter arrayAdapter= new List_view_ArrayAdapter(context, appManagers.getNameArray(cafeandbarsList), name, address, rating);
listView.setAdapter(arrayAdapter);
I think it help you.
Thanks
