Android ListView with Image, text and button

Android ListView with Image, text and button - android

I am trying to build a listview which contains outlet address in 5 lines,along with a status indicator image and a button. The following is the functionality I am trying to build.
When the list text is clicked - I want to open a activity.
When the button (COMP) is clicked - I want to open a different activity.
The image (tickmark) is a status indicator to inform the user whether the activity in a outlet is complete or not.
The list is populated from a SqliteDatabase. On clicking the button, I want to take the reference of the outlet and show different attributes of the outlet.
How do I integrate the button into the list view.
I have written the following code so far:
LISTVIEW.XML

first I have question.
why don't you make Model for Items?
Anyway if you want to make click event by element, just add click listener in your adapter.
so Example is here
add id in your whole layout.
( android:id="#+id/layout" )
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="3dp"
android:background="#FFFFFF"
android:layout_marginLeft="2dp"
android:layout_marginBottom="2dp"
android:descendantFocusability="blocksDescendants">
...
add click listener in your adapter
public class AltOutletAdapter extends BaseAdapter {
Context context;
ArrayList<String> ID;
ArrayList<String> O_Name;
ArrayList<String> O_Address1;
ArrayList<String> O_Address2;
ArrayList<String> City;
ArrayList<String> Phone;
ArrayList<String> iButton;
public LinearLayout linearLayout;
public AltOutletClickListener altOutletClickListener;
public AltOutletAdapter(Context context, ArrayList<String> ID, ArrayList<String> o_Name, ArrayList<String> o_Address1, ArrayList<String> o_Address2, ArrayList<String> city, ArrayList<String> phone, AltOutletClickListener listener) {
this.context = context;
this.ID = ID;
O_Name = o_Name;
O_Address1 = o_Address1;
O_Address2 = o_Address2;
City = city;
Phone = phone;
altOutletClickListener = listener;
}
#Override
public int getCount() {
return ID.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View child, ViewGroup parent) {
AltOutletAdapter.Holder holder;
LayoutInflater layoutInflater;
if (child == null) {
layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
child = layoutInflater.inflate(R.layout.alt_list_view, null);
holder = new AltOutletAdapter.Holder();
holder.O_Name = (TextView) child.findViewById(R.id.tvOutletNamealt);
holder.O_Address1 = (TextView) child.findViewById(R.id.tvOutletAddress1alt);
holder.O_Address2 = (TextView) child.findViewById(R.id.tvOutletAddress2alt);
holder.City = (TextView) child.findViewById(R.id.tvOutletCityalt);
holder.Phone = (TextView) child.findViewById(R.id.tvOutletPhonealt);
holder.linearLayout = (LinearLayout) child.findViewById(R.id.layout);
holder.iButton = (Button) child.findViewById(R.id.complianceButton);
child.setTag(holder);
} else {
holder = (AltOutletAdapter.Holder) child.getTag();
}
holder.O_Name.setText(O_Name.get(position));
holder.O_Address1.setText(O_Address1.get(position));
holder.O_Address2.setText(O_Address2.get(position));
holder.City.setText(City.get(position));
holder.Phone.setText(Phone.get(position));
holder.linearLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
altOutletClickListener.itemClickListener(v, position);
}
});
holder.iButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
altOutletClickListener.imageClickListener(v, position);
}
});
return child;
}
private class Holder {
TextView O_Name;
TextView O_Address1;
TextView O_Address2;
TextView City;
TextView Phone;
Button iButton;
ImageView imageView;
LinearLayout linearLayout;
}
public interface AltOutletClickListener {
void itemClickListener(View v, int position);
void imageClickListener(View v, int position);
}
}
when you call adapter in java, add click event as params.
ArrayList<String> test = new ArrayList<>();
AltOutletAdapter altOutletAdapter = new AltOutletAdapter(MainActivity.this, test, test, test, test, test, test, new AltOutletAdapter.AltOutletClickListener() {
#Override
public void itemClickListener(View v, int position) {
// when click layout
}
#Override
public void imageClickListener(View v, int position) {
// when click button
}
});
I just tested and use this.
But I think make Model is better.
ArrayList<String> test = new ArrayList<>();
ArrayList<Model> test = new ArrayList<>(); // it is better
**UPDATE : make Model **
simply, I make your Model Example.
make Model file.
public class AltOutlet {
private String name;
private String address1;
private String address2;
private String city;
private String phone;
public AltOutlet(String name, String address1, String address2, String city, String phone) {
this.name = name;
this.address1 = address1;
this.address2 = address2;
this.city = city;
this.phone = phone;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress1() {
return address1;
}
public void setAddress1(String address1) {
this.address1 = address1;
}
public String getAddress2() {
return address2;
}
public void setAddress2(String address2) {
this.address2 = address2;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
}
change your adapter
public class AltOutletAdapter extends BaseAdapter {
Context context;
ArrayList<AltOutlet> altOutletArrayList;
public LinearLayout linearLayout;
public AltOutletClickListener altOutletClickListener;
public AltOutletAdapter(Context context, ArrayList<AltOutlet> altOutletList, AltOutletClickListener listener) {
this.context = context;
altOutletArrayList = altOutletList;
altOutletClickListener = listener;
}
#Override
public int getCount() {
return altOutletArrayList.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View child, ViewGroup parent) {
AltOutletAdapter.Holder holder;
LayoutInflater layoutInflater;
if (child == null) {
layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
child = layoutInflater.inflate(R.layout.alt_list_view, null);
holder = new AltOutletAdapter.Holder();
holder.O_Name = (TextView) child.findViewById(R.id.tvOutletNamealt);
holder.O_Address1 = (TextView) child.findViewById(R.id.tvOutletAddress1alt);
holder.O_Address2 = (TextView) child.findViewById(R.id.tvOutletAddress2alt);
holder.City = (TextView) child.findViewById(R.id.tvOutletCityalt);
holder.Phone = (TextView) child.findViewById(R.id.tvOutletPhonealt);
holder.linearLayout = (LinearLayout) child.findViewById(R.id.layout);
holder.iButton = (Button) child.findViewById(R.id.complianceButton);
child.setTag(holder);
} else {
holder = (AltOutletAdapter.Holder) child.getTag();
}
holder.O_Name.setText(altOutletArrayList.get(position).getName());
holder.O_Address1.setText(altOutletArrayList.get(position).getAddress1());
holder.O_Address2.setText(altOutletArrayList.get(position).getAddress2());
holder.City.setText(altOutletArrayList.get(position).getCity());
holder.Phone.setText(altOutletArrayList.get(position).getPhone());
holder.linearLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
altOutletClickListener.itemClickListener(v, position);
}
});
holder.iButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
altOutletClickListener.imageClickListener(v, position);
}
});
return child;
}
private class Holder {
TextView O_Name;
TextView O_Address1;
TextView O_Address2;
TextView City;
TextView Phone;
Button iButton;
ImageView imageView;
LinearLayout linearLayout;
}
public interface AltOutletClickListener {
void itemClickListener(View v, int position);
void imageClickListener(View v, int position);
}
}
when you add item in java file, use Model
AltOutlet altOutlet = new AltOutlet("test", "address1", "address2", "city", "phone");
altOutlets.add(altOutlet);
AltOutletAdapter altOutletAdapter = new AltOutletAdapter(MainActivity.this, altOutlets, new AltOutletAdapter.AltOutletClickListener() {
#Override
public void itemClickListener(View v, int position) {
// when click layout
}
#Override
public void imageClickListener(View v, int position) {
// when click button
}
});

In your onBindViewHolder,, you can just switch the image as needed.
holder.fav.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
if(holder.fav.getTag() == R.drawable.fav_icon) {
unfav(position);
holder.fav.setImageResource(R.drawable.unfav_icon);
holder.fav.setTag(R.drawable.unfav_icon);
}
else {
fav(position);
holder.fav.setImageResource(R.drawable.fav_icon);
holder.fav.setTag(R.drawable.fav_icon);
}
}
});
In your onBindViewHolder() method, you can add the initial state :
if(holder.fav.getTag() == R.drawable.fav_icon)
holder.fav.setImageResource(R.drawable.fav_icon);
else
holder.fav.setImageResource(R.drawable.unfav_icon);

getting the selected item with checkbox in listview along side with the quantity number picker

i am creating a app that allows users to select the food they want and displaying the ordered food.
My listview has a checkbox, 3 textview and a numberpicker. I am now trying to get the selected items and quantity from the numberpicker and displaying on the next activity. I have tried some codes but unsure whether it works.
I am kinda new with android studio.How should i approach it from now on? Below are my codes
Listview row :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

I am assuming your CustomItem class has a boolean variable whose value can be retrieved by a getSelected() method.
Create a public static ArrayList like this in your Adapter class
public static ArrayList<CustomItem> arl_food=new ArrayList<>();
Inside your CustomLVAdapter() constructor add this
this.objectList=objectList;
arl_food.clear();
for(int i=0;i<this.objectList.size();i++)
{
arl_food.add(this.objectList.get(i));
}
Instead of creating a new CustomItem object, you should save the data to the particular object inside your ArrayList.
Add this code inside your CheckBox click event :
arl_food.get(position).setSelected(cb.isChecked());
Then inside your NumberPicker valueChanged event :
arl_food.get(position).setQty(String.valueOf(newVal));
In your Next Activity use this list like this :
for(int i=0;i<CustomLVAdapter.arl_food.size();i++)
{
if(CustomLVAdapter.arl_food.get(i).getSelected())
{
//Show the food item from your list and do your stuff here
}
}

Multiple TextView in ListView?

I have a ListView with two TextView that fill from DataBase but show me just one row :
MainActivity.java :
public class MainActivity extends ActionBarActivity {
public static final String DIR_SDCARD =Environment.getExternalStorageDirectory().getAbsolutePath();
public static final String DIR_DATABASE = DIR_SDCARD +"/Android/data/";
EditText editText;
DB db = new DB(MainActivity.this);
public String Titel_Drawer;
public String Titel_Drawert;
public String messageCursor;
public SQLiteDatabase sql;
public Cursor cursor;
public Cursor cursort;
public ArrayList<String> array;
public ArrayList<String> arrayt;
public static String PACKAGE_NAME;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PACKAGE_NAME = getApplicationContext().getPackageName();
File file= new File(DIR_DATABASE + PACKAGE_NAME + "/DB");
file.mkdirs();
db.GetPackageName(PACKAGE_NAME);
db.CreateFile();
try {
db.CreateandOpenDataBase();
} catch (IOException e) {
e.printStackTrace();
}
sql = db.openDataBase();
cursor = sql.rawQuery("SELECT Comment FROM WebSite_MetaDataDBBack", null);
cursort = sql.rawQuery("SELECT Title FROM WebSite_CategoryBack", null);
array = new ArrayList<String>();
if(cursor!=null)
{
if(cursor.moveToFirst())
{
do {
Titel_Drawer = cursor.getString(cursor.getColumnIndex("Comment"));
array.add(Titel_Drawer);
} while (cursor.moveToNext());
}
}
cursor.close();
arrayt = new ArrayList<String>();
if(cursort!=null)
{
if(cursort.moveToFirst())
{
do {
Titel_Drawert = cursort.getString(cursort.getColumnIndex("Title"));
arrayt.add(Titel_Drawert);
} while (cursort.moveToNext());
}
}
cursort.close();
final List<Contact> listOfContact = new ArrayList<Contact>();
listOfContact.add(new Contact(Titel_Drawert,Titel_Drawer));
ContactAdapter ConAdapter = new ContactAdapter(this,listOfContact);
ListView list = (ListView) findViewById(R.id.mainListView);
list.setAdapter(ConAdapter);
}
}
Here is my get and set in Contact.java:
public class Contact {
private String title;
private String description;
public Contact(String title, String description) {
super();
this.title = title;
this.description = description;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
And here is ContactAdapter.java :
public class ContactAdapter extends BaseAdapter implements OnClickListener {
private Context context;
private List<Contact> listContact;
public ContactAdapter(Context context, List<Contact> listContact) {
this.context = context;
this.listContact = listContact;
}
public int getCount() {
return listContact.size();
}
public Object getItem(int position) {
return listContact.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup viewGroup) {
Contact entry = listContact.get(position);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.drawer_layout_main, null);
}
TextView tvContact = (TextView) convertView.findViewById(R.id.rowTextView_Main);
tvContact.setText(entry.getTitle());
TextView tvPhone = (TextView) convertView.findViewById(R.id.rowTextView_Main2);
tvPhone.setText(entry.getDescription());
return convertView;
}
#Override
public void onClick(View view) {
}
}
My activity_main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/mainListView"
android:layout_width="fill_parent"
android:layout_height="300dp">
</ListView>
</LinearLayout>
My drawer_layout_main.xml :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/rowTextView_Main"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp" >
</TextView>
<TextView
android:id="#+id/rowTextView_Main2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp" >
</TextView>
</LinearLayout>

Your listOfContact only has 1 item:
final List<Contact> listOfContact = new ArrayList<Contact>();
listOfContact.add(new Contact(Titel_Drawert,Titel_Drawer));
ContactAdapter ConAdapter = new ContactAdapter(this,listOfContact);
So your getCount() returns 1.
public int getCount() {
return listContact.size();
}
Replace your listContact in the adapter with a List that has one element for each item you want a row for.

First of all, if you want to change the quantity value, you should have a variable representing quantity which you can change. You have included quantity value in the description text, which is bad design. What you should do is have a quantity variable int in the RowItem class as shown. You desc should just return a string from the quantity value as shown:
public class RowItem {
private int imageId;
private String title;
private int quantity = 0;
public RowItem(int imageId, String title, int quantity) {
this.imageId = imageId;
this.title = title;
this.quantity = quantity;
}
public int getImageId() {
return imageId;
}
public void setImageId(int imageId) {
this.imageId = imageId;
}
public String getDesc() {
return "Select " + quantity + " Item";
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public int getQuantity() {
return quantity;
}
public void setQuantity(int quantity) {
this.quantity = quantity;
}
#Override
public String toString() {
return title + "\n" + quantity;
}
}
In your activity, instead of storing descriptions, store quantities:
public static final int[] quantities = new int[]{ 0 };
In onCreate initialize the rowItems as follows
rowItems = new ArrayList<RowItem>();
for (int i = 0; i < titles.length; i++) {
RowItem item = new RowItem(images[i], titles[i], quantities[0]);
rowItems.add(item);
}
Finally, in your OnClickListener, get the quantity value, update it and set the new description.
final ViewHolder viewHolderFinal = holder;
final RowItem finalRowItem = rowItem;
holder.add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int quantity = finalRowItem.getQuantity(); // get the quantity for this row item
finalRowItem.setQuantity(quantity + 1); // update it by adding 1
viewHolderFinal.txtDesc.setText(finalRowItem.getDesc()); // set the new description (that uses the updated qunatity)
}
});
holder.sub.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int quantity = finalRowItem.getQuantity(); // get the quantity for this row item
finalRowItem.setQuantity(quantity - 1); // update it by subtracting 1
viewHolderFinal.txtDesc.setText(finalRowItem.getDesc()); // set the new description (that uses the updated qunatity)
}
});
*Note: * I have compiled and run this code. So if you do everything as I mentioned it will work.

Unable to refresh the ListView

After i click "more" button, it suppose will extend the listview from 10 to 20.
However after clicked, the list view did not extend and remain original size.
It only can keep the position of scroll bar. This is half of what i need.
newsid = new int[webservice.news.size()];
title = new String[webservice.news.size()];
date = new String[webservice.news.size()];
imagepath = new String[webservice.news.size()];
for (int i = 0; i < webservice.news.size(); i++) {
newsid[i] = webservice.news.get(i).getID();
title[i] = webservice.news.get(i).getNtitle();
date[i] = webservice.news.get(i).getNArticalD();
imagepath[i] = webservice.news.get(i).getImagePath();
}
adapter = new CustomAdapter_ParticularCategoryAllNews(this, title,
date, imagepath);
lv.addFooterView(footermore);
if (constant.isOnline()) {
lv.addFooterView(constant.AdMob());
}
TextView titletext = (TextView) findViewById(R.id.text_pagetitle);
titletext.setText(pagetitletext.toString());
lv.setAdapter(adapter);
This is call when launch activity.
btnmore.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
for (int i = 0; i < webservice.news.size(); i++) {
newsid[i] = webservice.news.get(i).getID();
title[i] = webservice.news.get(i).getNtitle();
date[i] = webservice.news.get(i).getNArticalD();
imagepath[i] = webservice.news.get(i).getImagePath();
}
adapter.setTitle(title);
adapter.setDate(date);
adapter.setImagepath(imagepath);
position = lv.getFirstVisiblePosition();
lv.smoothScrollToPosition(position);
adapter.notifyDataSetChanged();
This is what i call after i click "more button". However the list did not extend from 10 to 20 items.
public class CustomAdapter_ParticularCategoryAllNews extends BaseAdapter {
private Activity activity;
private String[] title, date, imagepath;
private static LayoutInflater inflater = null;
private ImageLoader_Loader imageLoader;
private WindowManager wm = null;
private Display display;
private Config_ConstantVariable constant;
public CustomAdapter_ParticularCategoryAllNews(Activity a, String[] title,
String[] date, String[] imagepath) {
activity = a;
this.title = title;
this.date = date;
this.imagepath = imagepath;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
wm = (WindowManager) activity.getSystemService(Context.WINDOW_SERVICE);
imageLoader = new ImageLoader_Loader(activity.getApplicationContext());
constant = new Config_ConstantVariable(activity);
}
public int getCount() {
return title.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public void setTitle(String[] title) {
this.title = title;
}
public void setDate(String[] date) {
this.date = date;
}
public void setImagepath(String[] imagepath) {
this.imagepath = imagepath;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.main_particularcategoryallnewslist,
parent, false);
LinearLayout linear = (LinearLayout) vi.findViewById(R.id.layout_image);
ImageView imageview = (ImageView) vi
.findViewById(R.id.image_categoryallnewstitle);
TextView titletext = (TextView) vi
.findViewById(R.id.text_categoryallnewstitle);
TextView datetext = (TextView) vi.findViewById(R.id.text_newsdate);
if (!imagepath[position].toString().equals("no picture")) {
imageview.setVisibility(View.VISIBLE);
linear.setVisibility(View.VISIBLE);
imageLoader.DisplayImage(imagepath[position], imageview);
} else {
imageview.setVisibility(View.GONE);
imageview.setImageDrawable(null);
linear.setVisibility(View.GONE);
display = wm.getDefaultDisplay();
int screenWidth = display.getWidth();
titletext.setWidth(screenWidth);
}
if (constant.getscreenresolution() >= 800 && constant.ScreenOrientation() == 1) {
titletext.setTextSize(TypedValue.COMPLEX_UNIT_PX, 30);
datetext.setTextSize(TypedValue.COMPLEX_UNIT_PX, 20);
}
titletext.setText(title[position].toString());
datetext.setText(date[position].toString());
return vi;
}
}
This is the CustomAdapter class.

In your adapter add:
public void setTitle(String[] title) {
this.title = title;
}
public void setDate(String[] date) {
this.date = date;
}
public void setImagepath(String[] imagepath) {
this.imagepath = imagepath;
}
When the more button is pressed call the three methods above with arrays containing 20 objects. Then call notifyDataSetChanged on your adapter.
Update:
This is working for me:
Activity:
public class HelpProjectActivity extends Activity {
private ArrayList<Item> items;
private boolean extend = false;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
createArray();
ListView lv = (ListView)findViewById(R.id.list);
lv.setAdapter(new HelpListAdapter());
}
private void createArray() {
items = new ArrayList<Item>();
for(int i = 0; i < 20; i++) {
Item item = new Item();
item.title = "Title " + i;
item.subtitle = "Subtitle " + i;
item.image = "default";
items.add(item);
}
}
public void morePressed(View v) {
extend = !extend;
Button b = (Button) findViewById(R.id.button);
b.setText(extend ? R.string.less_button : R.string.more_button);
ListView lv = (ListView)findViewById(R.id.list);
((BaseAdapter)lv.getAdapter()).notifyDataSetChanged();
}
private class HelpListAdapter extends BaseAdapter {
#Override
public int getCount() {
if (extend) {
return items.size();
}
return items.size()/2;
}
#Override
public Object getItem(int pos) {
return items.get(pos);
}
#Override
public long getItemId(int pos) {
return pos;
}
#Override
public View getView(int pos, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
v = View.inflate(getApplicationContext(), R.layout.litst_item, null);
}
Item item = items.get(pos);
TextView titleText = (TextView) v.findViewById(R.id.list_item_title);
titleText.setText(item.title);
TextView subtitleText = (TextView) v.findViewById(R.id.list_item_subtitle);
subtitleText.setText(item.subtitle);
ImageView image = (ImageView) v.findViewById(R.id.list_image);
if (item.image.equalsIgnoreCase("default")) {
image.setImageResource(R.drawable.default_list_image);
} else {
// what ever
}
return v;
}
}
}
