Find the selected check boxes in a list view Android

I am working on a project and in that I want to get the track of items that are selected (check box) from a list view.
Is there any way of doing it?
Code so far is below;
Main Activity
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.ListView;
public class MainActivity extends Activity {
ListView lv;
Model[] modelItems;
CheckBox ONE,TWO,THREE;
Button MultiData;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.listView1);
modelItems = new Model[5];
modelItems[0] = new Model("pizza", 0);
modelItems[1] = new Model("burger", 0);
modelItems[2] = new Model("olives", 0);
modelItems[3] = new Model("orange", 0);
modelItems[4] = new Model("tomato", 0);
CustomAdapter adapter = new CustomAdapter(this, modelItems);
lv.setAdapter(adapter);
}
}
CustomAdapter
import android.app.Activity;
import android.content.Context;

import android.view.View;

public class CustomAdapter extends ArrayAdapter {
Model[] modelItems = null;
Context context;
public CustomAdapter(Context context, Model[] resource) {
super(context, R.layout.row1, resource);
this.context = context;
this.modelItems = resource;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
convertView = inflater.inflate(R.layout.row1, parent, false);
TextView name = (TextView) convertView.findViewById(R.id.textView1);
CheckBox cb = (CheckBox) convertView.findViewById(R.id.checkBox1);
name.setText(modelItems[position].getName());
if (modelItems[position].getValue() == 1)
cb.setChecked(true);
else
cb.setChecked(false);
return convertView;
}
}
Model
public class Model{
String name;
int value; /* 0 -> checkbox disable, 1 -> checkbox enable */
Model(String name, int value){
this.name = name;
this.value = value;
}
public String getName(){
return this.name;
}
public int getValue(){
return this.value;
}
}

#Override
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
convertView = inflater.inflate(R.layout.row1, parent, false);
TextView name = (TextView) convertView.findViewById(R.id.textView1);

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
modelItems[position].getValue() == 1;
}else{
modelItems[position].getValue() == 0;
}
}
});
return convertView;
}

try this
create Boolean array same as your modelItems size and store true false value in that array
Step 1 : by default store all value false in array
Step 2 : update value in array on checkbox check state change

Add the code below before return convertView; then modelItems array will be updated every time a checkbox is checked/unchecked
final int posFinal = position;
cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
modelItems[posFinal].setValue( b ? 1 : 0);
}
});

new a list to keep selected items:
List<Model> selectedList = new ArrayList<>();
private List getSelectedList(){
if(!selectedList.isEmpty()) selectedList.clear();
for (int i=0;i<array.length;i++){
if(modelItems [i].getValue==1){
selectedList.add(modelItems [i]);
}
}
return selectedList;
}
set onCheckedChangeListener for CheckBox in getView:
cb.setOnCheckedChangeListener(new
CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
modelItems[position].setValue(1);
}else{
modelItems[position].setValue(0);
}
}
});

// Replace your code with bellow, on the click of button it will show selected checkbox name in alert dialog.

Please help me through this I need to submit this by tomorrow.

Use this
convertView = inflater.inflate(R.layout.customlist_massage,null ,false );
Instead this
convertView = inflater.inflate(R.layout.customlist_massage,null );

Why you are extending the adapter class ArrayAdapter.
If You want to show something on listview you have to extend it to BaseAdapter OR Recyclerview Adapter.
You dont have any getCount() method in ArrayAdapter see this example::
public class Adapter extends BaseAdapter {
LayoutInflater li;
ArrayList<String> title, details;
Context con;
DataBaseHelper db;
TextView txttitle, txtdetails, txtDate;
Intent in;
public static int i = 1;
View view;
public Adapter (Context cont, ArrayList<String> news_id, ArrayList<String> news) {
this.title = news_id;
this.details = news;
this.con = cont;
li = (LayoutInflater) con.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
System.out.println("title.size() " + title.size());
return title.size();
}
#Override
public Object getItem(int arg0) {
return arg0;
}
#Override
public long getItemId(int arg0) {
return arg0;
}
#Override
public View getView(int arg0, View arg1, ViewGroup arg2) {
if (arg1 == null) {
arg1 = li.inflate(R.layout.adapter_daycare, null);
txttitle = (TextView) arg1.findViewById(R.id.title);
txtdetails = (TextView) arg1.findViewById(R.id.details);
txtDate = (TextView) arg1.findViewById(R.id.txtdate);
view = (View) arg1.findViewById(R.id.view);
}
String date = new SimpleDateFormat("dd/MM/yyyy").format(new Date());
System.out.println(" formattedDate " + date);
txttitle.setText(title.get(arg0).toString());
txtdetails.setText(details.get(arg0).toString());
txtDate.setText(date);
return arg1;
}
}

How to make a ListView with 4 sub items onClick Item detail View

How I can create a list view with 4 subitems which can contain Name, Phone,Mobile,Email
I am very new android learner
Ex:

You need to create your own custom adapter and custom view.
Check out the following tutorials -
Tutorial 1
Tutorial 2
Let me know If you having trouble understanding the concept.
Here is a working code -
Custom Adapter -
public class CustomAdapter extends ArrayAdapter<CustomObject> {
public CustomAdapter(Context context, List<CustomObject> objects) {
super(context, -1, objects);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
View view = convertView;
if (view == null) {
view = View.inflate(getContext(), R.layout.list_view_item, null);
viewHolder = new ViewHolder();
viewHolder.setView(view);
} else {
viewHolder = (ViewHolder) view.getTag();
}
viewHolder.mName.setText(getItem(position).getName());
viewHolder.mPhone.setText(getItem(position).getPhone());
viewHolder.mMobile.setText(getItem(position).getMobile());
viewHolder.mEmail.setText(getItem(position).getEmail());
return view;
}
private class ViewHolder {
public TextView mName;
public TextView mPhone;
public TextView mMobile;
public TextView mEmail;
public void setView(View view) {
mName = (TextView) view.findViewById(R.id.textView);
mPhone = (TextView) view.findViewById(R.id.textView2);
mMobile = (TextView) view.findViewById(R.id.textView3);
mEmail = (TextView) view.findViewById(R.id.textView4);
view.setTag(this);
}
}
}
Custom Object -
public class CustomObject implements Parcelable {
public String mName;
public String mPhone;
public String mMobile;
public String mEmail;
public CustomObject(String name, String phone, String mobile, String email) {
mName = name;
mPhone = phone;
mMobile = mobile;
mEmail = email;
}
private CustomObject(Parcel parcel) {
readFromParcel(parcel);
}
public String getName() {
return mName;
}
public void setName(String name) {
mName = name;
}
public String getPhone() {
return mPhone;
}
public void setPhone(String phone) {
mPhone = phone;
}
public String getMobile() {
return mMobile;
}
public void setMobile(String mobile) {
mMobile = mobile;
}
public String getEmail() {
return mEmail;
}
public void setEmail(String email) {
mEmail = email;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(mName);
dest.writeString(mPhone);
dest.writeString(mMobile);
dest.writeString(mEmail);
}
private void readFromParcel(Parcel parcel) {
mName = parcel.readString();
mPhone = parcel.readString();
mMobile = parcel.readString();
mEmail = parcel.readString();
}
public static final Creator<CustomObject> CREATOR = new Creator<CustomObject>() {
#Override
public CustomObject createFromParcel(Parcel source) {
return new CustomObject(source);
}
#Override
public CustomObject[] newArray(int size) {
return new CustomObject[0];
}
};
}
Your Activity -
public class MainActivity extends Activity {

Assinging the values of cursor to object

I'm working on showing list of contacts with checkbox. I tried implementing my own cursor adapter and it is checkable. But once I check that value I want the contacts to be stored in ContactPerson object. But when I tried it is showing null pointer exception(That's why I commented out that code). My CursorAdapter code goes like this.

Can anyone please suggest me how to use that Contact person class in this adapter.
public class ContactPerson {
String name= null, number = null;
boolean Selected = false;
public ContactPerson(String PersonName, String PhoneNumber){
this.name = PersonName;
this.number= PhoneNumber;
}
public String getName(){
return name;
}
public boolean isSelected(){
return Selected;
}
public void setSelected(boolean selected){
this.Selected = selected;
}
public String getPhoneNumber(){
return number;
}
}

Check this code. It worked for me. Best of luck.

How to add EditText in listview and get its value dynamically in all the rows?

I have Checkbox and EditText and a Textview in a listView. It gets value for the text view from a list. Checkbox will be checked dynamically. In the same way EditText also can be entered dynamically. Now my problem is, When i scroll the list view (up and down) after entering the text in the Edit text, I could not get the typed value. I check the check box also like that. But using the position, I set it correct. I Could not know How to set the EditText value to the list properly. Please help me. Here is my code:

There is no error in the code. It runs well. I could maintain the checkbox position and display at the same position even I scroll up and down. But I could not get and set the EditText value properly. Please Help me out.
Thanks in advance.

you can achieve this using the custom list view.
find the example of listview with edittext is here

Easy and beautiful solution to handle EditText with listView:
(Does not require holder or RecycleView or anything else)
Brief explaination:
1) In getView method when you inflate the view, apply the myTextWatcher the editText. Pass this EditText to the myTextWatcher()
2) Inside getView Method find that EditText and set position as editText.setTag [Each time. not only when the view was inflated.]
3) Define MyTextWatcher. It should have reference to EditText on which it is applied.
4) myTextWatcher.onTextChanged() will read the tag set to the editText and do the required work
Modify your getView() method of Adapter class:
#Override
public View getView(int position, View convertView, final ViewGroup parent) {
if(convertView==null){
convertView = LayoutInflater.from(getContext()).inflate(R.layout.single_row_layout,parent,false);
EditText et = convertView.findViewById(R.id.idEditText);
et.addTextChangedListener(new MyTextWatcher(et));
}
//This is again required to find reference to EditText... so that 'position' can be applied on to it as 'tag' EACH time.
EditText editText = (EditText) convertView.findViewById(R.id.idEditText);;
//This tag will be used inside onTextChanged()
editText.setTag(position);
}
Define your MyTextWatcher class as:
private class MyTextWatcher implements TextWatcher{
//int position;
EditText et;
public MyTextWatcher(EditText editText){
this.et = editText;
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
if(et.getTag()!=null){
// This is required to ensure EditText is edited by user and not through program
if(et.hasFocus()){
int position = (int)et.getTag();
String newText = et.getText()+"";
//Implement your actions here........
//you can get require things/ views from listView.getChildAt(position)..
}
}
}
#Override
public void afterTextChanged(Editable s) {
}
}

Just keep viewHolder.address.setTag(position) and it works perfect cheers.
