Android ListView with Image, text and button

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
}
});

mproduct.remove(position) or notifyDataSetChange() does not work inside getView method

I have checked most of the places but i could not get the precise answer for this question.
problem in function : getView
What is the problem : When if condition gets true,
mproduct.remove((position));
notifyDataSetChanged();
both statement suppose to work.
// here mproduct is object of ArrayList;
If i write Log.e(); It displays promt message.
Thanks in advance.

Null Pointer Exception at Imageview in Custom List View

I have a custom list view with a TextView and three ImageViews. On click of image view I want to start a new activity and pass the data of specific position to next activity. But I am getting null pointer exception.
I have use this for refernce http://jmsliu.com/2444/click-button-in-listview-and-get-item-position.html
Here is my code. This is main Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_employees);
toolbar = (Toolbar) findViewById(R.id.app_bar);
toolbar.setTitle("Manage Employees");
nPregress = (ProgressBar) findViewById(R.id.toolbar_progress_bar);
nPregress.setVisibility(View.GONE);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
mainList = (ListView) findViewById(R.id.manageemployeeList);
employee1 = new ArrayList<Pojo>();
tii = new ArrayList<String>();
SharedPreferences prefs = getSharedPreferences("MyPref4", MODE_PRIVATE);
Set<String> set1 = prefs.getStringSet("employeename", null);
if (set1 != null ) {
List<String> nameList = new ArrayList<String>(0);
nameList.addAll(set1);
for (int i = 0; i < set1.size(); i++) {
pojo = new Pojo();
pojo.setMgEmpName(nameList.get(i));
employee1.add(pojo);
Log.e("namemmee0", "" + nameList.get(i));
}
mainAdapter = new EmployeesAdapter(EmployeesActivity.this, employee1);
mainList.setAdapter(mainAdapter);
} else {
new NetCheck().execute();
}
new NetCheck().execute();
emp_edit = (ImageView) findViewById(R.id.imgedit);
emp_edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View parentRow = (View) v.getParent();
mainList = (ListView) parentRow.getParent();
final int position = mainList.getPositionForView(parentRow);
String emp_name = employee1.get(position).getMgEmpName().toString();
Intent i = new Intent(EmployeesActivity.this, EditEmployee.class);
i.putExtra("empname", emp_name);
startActivity(i);
}
});
}
I am getting exception at this line
emp_edit.setOnClickListener(new View.OnClickListener()
How can i do this? Please help me.

Try this, There may be position mismatch when store it locally
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(activity1, EditEmployee.class);
intent.putExtra("empname", "" + data1.get(position).getMgEmpName());
intent.putExtra("empmobile", "" + data1.get(position).getMgEmpContact());
intent.putExtra("empemail", "" + data1.get(position).getMgEmpEmail());
intent.putExtra("empappcost", "" + data1.get(position).getMgEmpAppCost());
activity1.startActivity(intent);
}
});

Your getView() method should look like this in your adapter:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
pojo = data1.get(position);
ViewHolder holder;
if (pojo != null) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.manage_emp_list, parent, false);
holder = new ViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.categoryName.setText(pojo.getMgEmpName());
//holder.edit.setOnClickListener()...
//holder.delete.setOnclickListener()...
}
return convertView;
}
And add a static class in to your Adapter:
static class ViewHolder {
TextView categoryName;
ImageView edit;
ImageView delete;
ImageView historyy;
public ViewHolder(View view) {
categoryName = (TextView) v.findViewById(R.id.employeeName);
edit = (ImageView) v.findViewById(R.id.imgedit);
delete = (ImageView) v.findViewById(R.id.imgdelete);
historyy = (ImageView) v.findViewById(R.id.imgHistory);
}
}

ImageButton in GridView get click position?

I'm trying create a GridView with some ImageButtons but I can't make onClick of these ImageButtons. I want get these clicks to open other Activitys/Fragments but I can't get position of ImageButton to do it.
How could I get position of ImageButton to click ?

});

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;

} 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.

private ArrayList<Item> items;

}
}

((BaseAdapter)lv.getAdapter()).notifyDataSetChanged();
