Why Custom ArrayAdapter not showing TextView in a ListView

I have made a custom ArrayAdapter and tried to add the another TextView "Breed" of the animals, but when i execute the program , its not showing the Breed. Where am i doing wrong ? I am scratching my head since long. please help where is the mistake ?
MainActivity.Java
public class MainActivity extends AppCompatActivity {
ListView simpleList;
ArrayList<Item> animalList=new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
simpleList = (ListView) findViewById(R.id.simpleListView);
animalList.add(new Item("Lion",R.drawable.lion,"Khatarnak"));
animalList.add(new Item("Tiger",R.drawable.tiger,"Fudu"));
animalList.add(new Item("Monkey",R.drawable.monkey,"Lallu"));
animalList.add(new Item("Elephant",R.drawable.elephant,"Jabardast"));
animalList.add(new Item("Dog",R.drawable.dog,"ItemDog"));
animalList.add(new Item("Cat",R.drawable.cat,"MeeMee"));
MyAdapter myAdapter=new MyAdapter(this,R.layout.list_view_items,animalList);
simpleList.setAdapter(myAdapter);
}
}
MyAdapter.Java
public class MyAdapter extends ArrayAdapter<Item> {
ArrayList<Item> animalList = new ArrayList<>();
public MyAdapter(Context context, int textViewResourceId, ArrayList<Item> objects) {
super(context, textViewResourceId, objects);
animalList = objects;
}
#Override
public int getCount() {
return super.getCount();
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.list_view_items, null);
TextView textView = (TextView) v.findViewById(R.id.textView);
ImageView imageView = (ImageView) v.findViewById(R.id.imageView);
TextView breedView = (TextView)v.findViewById(R.id.breed);
textView.setText(animalList.get(position).getAnimalName());
imageView.setImageResource(animalList.get(position).getAnimalImage());
breedView.setText(animalList.get(position).getBreed());
return v;
}
}
Item.Java
public class Item {
String animalName;
int animalImage;
String breedName;
public String getBreed() {
return breedName;
}
public void setBreed(String breed) {
this.breedName = breedName;
}
public Item(String animalName,int animalImage,String breedName)
{
this.animalImage=animalImage;
this.animalName=animalName;
this.breedName = breedName;
}
public String getAnimalName()
{
return animalName;
}
public int getAnimalImage()
{
return animalImage;
}
}

This is most likely a problem with the linear layout for each item. The orientation is horizontal, which lays each view one after the other horizontally. The problem is that the text view for the animal type has a width of fill_parent leaving no space for the breed view. If you change it to wrap_content it'll probably work for some of the cases, but might not work with everything.
In any case I think this is a problem with the views' positions and sizes. Try and move them around. Perhaps even a simple change would be placing them vertically:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/imageView"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="5dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Demo"
android:textColor="#000" />
<TextView
android:id="#+id/breed"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Breed"
android:textColor="#000" />
</LinearLayout>
</LinearLayout>
There's perhaps a more efficient way of doing this, but this is just an example. The inner linear layout places one text view on to of the other.
PS: your getCount method is not really doing anything. You can remove it.

replace your layout with my code your issue will resolve.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_width="50dp"
android:layout_height="50dp"
android:padding="5dp" />
<TextView
android:id="#+id/textView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="1"
android:text="Demo"
android:textColor="#000" />
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"

Row in listview not preserve the makeover and appears repeated

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.

Custom ListAdapter Never Calling GetView

I've been trying to figure out what is going on with this for a little while, maybe I have been staring at it too long... I feel like it's something simple.
Here is my ListActivity class
public class ResultsListActivity extends ListActivity {
private ArrayList<Result> results = new ArrayList<Result>();
private ListView list;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sp_history);
//set up list
list = new ListView(this);
}
#Override
protected void onResume()
{
super.onResume();
results = openAndQueryDatabase();
displayResultList();
}
private void displayResultList() {
list.setAdapter(new HistoryArrayAdapter(this.getBaseContext(), results));
}
private ArrayList<Result> openAndQueryDatabase() {
DatabaseHandler dbh = new DatabaseHandler(getBaseContext());
ArrayList<Result> toReturn = dbh.getAllResults();
return toReturn;
}//open and query database
public int getCount() {
return null == results ? 0 : results.size();
}
}
Here is my ListAdapterClass
public class HistoryArrayAdapter extends ArrayAdapter<Result> {
private final Context context;
private final ArrayList<Result> values;
private int layoutId;
public HistoryArrayAdapter(Context context, ArrayList<Result> results) {
super(context, R.layout.history_row, results);
this.context = context;
this.layoutId = R.layout.history_row;
this.values = results;
}
#Override
public int getCount() {
return values.size();// more than zero
}
#Override
public Result getItem(int position) {
return values.get(position);// may be in your case
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView==null)
{
// inflate the layout
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
convertView = inflater.inflate(layoutId, parent, false);
}// if convertView == null
//set up our views
TextView uploadSpeed = (TextView) convertView.findViewById(R.id.upload_speed_history);
TextView downloadSpeed = (TextView) convertView.findViewById(R.id.download_speed_history);
TextView pingTime = (TextView) convertView.findViewById(R.id.ping_history_text);
TextView networkName = (TextView) convertView.findViewById(R.id.history_network_name);
TextView dateTime = (TextView) convertView.findViewById(R.id.history_dateTime);
ImageView imageView = (ImageView) convertView.findViewById(R.id.history_connection);
//set up our values
Result row = values.get(position);
uploadSpeed.setText(row.getUpload());
downloadSpeed.setText(row.getDownload());
pingTime.setText(row.getPingTime());
networkName.setText(row.getNetworkName());
dateTime.setText(row.getDateTime());
if(row.getNetworkType() == "NETWORK_WIFI")
imageView.setImageResource(R.drawable.ico_wifi);
else
imageView.setImageResource(R.drawable.ico_cell);
return convertView;
}//getView
}

Things that I do know... I do have results. I can see it in the debugger and they are populated fine. I know I have a few things that look like unnecessary methods, there is work to be done there to make sure the app isn't in the middle of a process before it populates the list.

Change your onCreate() like below,
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sp_history);
//set up list
list = getListView();
}

AS you've stated that you are using Asynchronous call to get the Database results... even though while debugging you are getting the results, chances are that while actually running, the results might be getting after the adapter has been set in the following line hence the length of results in adapter is 0, so your getView() isn't getting a callback.
Either can have a Custom Listener that will get a call back when the results have been fetched and then you can set the adapter to the listview OR another solution might be to hold the instance of your adapter and then add the acquired results to the adapter using the Adapter.add() method and then call Adapter.notifyDataSetChanged() method.
Edit:- Also as you are using ListActivity, there's no need to create a new ListView instance. Just call getListView() method to obtain the ListView instance as the above answerer suggested.

How to create a listView with multiple views in a row.

I am writing an app that requires the user to enter some details into a form. The form initially has 3 EditText views in a row. When the user enters some data in the last editText, the onFocusChangeListener should initiate a new row.
This is what I want to do.
How can I create 3 editText views in a single listView row at runtime?

To create a listView with multiple views in a row, you need to customize your adapter, so it can take the form of your row from a source XML -that you should create- and puts it into your listView, here is an example based on BaseAdapter:
This is your Xml source that contains the form of your Row:
espaceclientuploadsource.xml :
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:addStatesFromChildren="true" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:addStatesFromChildren="true" >
<ImageView
android:id="#+id/Uplodimage"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="15dp"
android:src="#drawable/bingo" />
<TextView
android:id="#+id/UploadedProductName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginLeft="20dp"
android:layout_marginTop="24dp"
android:layout_toRightOf="#+id/Uplodimage"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/UplodedProductPrice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/UploadedProductName"
android:layout_below="#+id/UploadedProductName"
android:layout_marginTop="16dp"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />
<ImageView
android:id="#+id/UploadedStatus"
android:layout_width="15dp"
android:layout_height="15dp"
android:layout_above="#+id/UplodedProductPrice"
android:layout_alignParentRight="true"
android:layout_alignTop="#+id/UploadedProductName"
android:layout_marginRight="27dp"
android:src="#drawable/bingo" />
<ImageView
android:id="#+id/ImageViewDelete"
android:layout_width="15dp"
android:layout_height="15dp"
android:layout_alignBottom="#+id/UplodedProductPrice"
android:layout_alignLeft="#+id/UploadedStatus"
android:clickable="true"
android:src="#drawable/bingo" />
</RelativeLayout>
Then you need to create an XML file that containes your ListView:
espaceclientuploads:
<EditText
android:id="#+id/login"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10" >
<requestFocus />
</EditText>
<EditText
android:id="#+id/password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:inputType="textPassword" />
<Button
android:id="#+id/submit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="submit"
android:text="Button" />
</LinearLayout>
Next is your adapter, it's role is to use your sourceXML as your row Format,
UploadedAdapter :
public class UploadedAdapter extends BaseAdapter
{
List<Article> lesArticles;
DataSource produitSource;
LayoutInflater inflater;
String path= Environment.getExternalStorageDirectory().toString()+File.separator+"Bingo";
public UploadedAdapter(Context context, List<Article> lesArticles)
{
inflater=LayoutInflater.from(context);
this.lesArticles = lesArticles;
}
#Override
public int getCount()
{
return lesArticles.size();
}
#Override
public Object getItem(int position)
{
return lesArticles.get(position);
}
#Override
public long getItemId(int position)
{
return position;
}
private class ViewHolder
{
TextView nomduProduit;
TextView prixDuProduit;
ImageView status;
ImageView imageDuProduit;
ImageView delete;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView==null)
{
holder=new ViewHolder();
convertView = inflater.inflate(R.layout.espaceclientuploadsource, null);
holder.nomduProduit = (TextView)convertView.findViewById(R.id.UploadedProductName);
holder.prixDuProduit = (TextView)convertView.findViewById(R.id.UplodedProductPrice);
holder.imageDuProduit = (ImageView)convertView.findViewById(R.id.Uplodimage);
holder.status = (ImageView)convertView.findViewById(R.id.UploadedStatus);
holder.delete=(ImageView)convertView.findViewById(R.id.ImageViewDelete);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
Drawable drawableImage = new BitmapDrawable(bitmapImage);
holder.imageDuProduit.setImageDrawable(drawableImage);
holder.nomduProduit.setText(lesArticles.get(position).getNomArticle());
holder.prixDuProduit.setText(lesArticles.get(position).getPrix());
holder.delete.setImageResource(R.drawable.delete);
return convertView;
}
}
As you can see, your adapter extends the baseAdapter which is an abstract class, so you need to Override its method.
Finally it's your activity that will display your listView:
public class EspaceClientUplodedProducts extends Activity{
List<Article> lesArticle= new ArrayList<Article>();
ListView lvListe;
UploadedAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.espaceclientuploads);
lvListe= (ListView)findViewById(R.id.UploadListView);
adapter = new UploadedAdapter(this, lesArticle);
lvListe.setAdapter(adapter);
lvListe.setOnItemClickListener(this);
}
}

android list inside layout

i am working on an Android app that needs showing a list[table], inside the layout[view]
I come from iPhone dev objC land, and i have an app that shows a table[list] inside the view[layout]
So how to show a list inside my layout, and place it to specified location [center],
ps. I havent found a list in the graphical layout editor of the xml, where is the list[table]?
2. I have done some tests with list views, but is a view, that replace the xml view, i want it inside my xml,,
thanks a lot!

Yes, of course, you can do that
1) you need to have listholder.xml here, you can scratch anything in you layout view, either imageview, textview..etc. just don't forget to add ListView inside it. for example:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/head_logo_bg">
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_label">
<TextView
android:id="#+id/city_txt"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:layout_gravity="center"
android:text="Sydney"
android:textStyle="bold"
android:textSize="17sp"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="40sp">
<ListView
android:id="#android:id/list"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_centerVertical="true"
android:scrollingCache="false"/>
</LinearLayout>
2) For custom your own list item, you have to create listitem.xml i.e.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/listitemone"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="10sp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:orientation="vertical">
<ImageView android:id="#+id/user_image"
android:layout_width="80px" android:layout_height="80px"
android:layout_alignParentLeft="true"
android:layout_marginRight="5px"
android:src="#drawable/icon"
/>
</LinearLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5sp"
android:orientation="vertical">
<TextView
android:id="#+id/date_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/date"
android:textStyle="bold"
android:textSize="16sp" />
<TextView
android:id="#+id/date_value"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignBaseline="#id/date_label"
android:layout_marginRight="20sp"
android:textColor="#FFF"
android:text="MM/dd/YYYY"
android:textStyle="bold"
android:textSize="16sp" />
</RelativeLayout>
</LinerLayout>
3) create customAdapter in your activity, it would look like this;
public class MyListActivity extends ListActivity {
private ArrayList<Yourdata> yourdata = new ArrayList<Youdata>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listholder);
// yourdata might be array, arraylist etc.
MyCustomAdapter listadapter = new MyCustomAdapter(this, R.layout.listitem, yourdata);
setListAdapter(listadapter);
}
private class MyCustomAdapter extends ArrayAdapter<Yourdata>{
//this case, i use Yourdata as type
private ArrayList<Yourdata> items;
public PreviousAdapter(Context context, int textViewResourceId,
ArrayList<Yourdata> items) {
super(context, textViewResourceId, items);
this.items = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if(v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listitem, null);
}
Yourdata yt = items.get(position);
if(yt != null){
// Don't forget to use v.findView...., otherwise, it might force close when run app.
TextView dateStr = (TextView)v.findViewById(R.id.date_value);
dateStr.setText(yt.getDate());
}
return v;
}
}
}
P.S. the above code might not exactly right... just give you an idea :)
