this.phonebookList.addAll(pbList);

}

private class ViewHolder {

}

holder.selected.setTag(state);

return convertView;

}

}

private void checkButtonClick() {

Button myButton = (Button) findViewById(R.id.findSelected);

myButton.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

ArrayList<Phonebook> stateList = dataAdapter.phonebookList;

StringBuffer sb = new StringBuffer();

for (int i = 0; i < stateList.size(); i++) {

Phonebook state = stateList.get(i);

if (state.isChecked()) {

//Get selected contact information

//sb.append("\nImage URI:" + state.getImgUri().toString());

}

}

Toast.makeText(context, ":" + sb.toString(), Toast.LENGTH_LONG)

.show();

}

});

}

ProgressDialog mProgressDialog;

Intent i;

private class LongOperation extends AsyncTask<Void, Void, Void> {

@Override

protected Void doInBackground(Void... params) {

runOnUiThread(new Runnable() {

@Override

public void run() {

ArrayList<Phonebook> phonebookList = new ArrayList<Phonebook>();

ContentResolver cr = getContentResolver();

Cursor cur = cr.query(

ContactsContract.Contacts.CONTENT_URI, null, null,

null, null);

if (cur.getCount() > 0) {

while (cur.moveToNext()) {

String id = cur

.getString(cur

.getColumnIndex(ContactsContract.Contacts._ID));

String name = cur

.getString(cur

.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

if (Integer

.parseInt(cur.getString(cur

.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {

// get the phone number

Cursor pCur = cr

.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,

null,

ContactsContract.CommonDataKinds.Phone.CONTACT_ID

+ " = ?",

new String[] { id }, null);

while (pCur.moveToNext()) {

String phone = pCur

.getString(pCur

.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

Uri uri = Utils

.getPhotoUri(

Long.parseLong(Utils

phone,

context)),

context);

// ---------------------------------------------------------------------------

Phonebook _states = new Phonebook(name,

phone, false, uri);

phonebookList.add(_states);

// ---------------------------------------------------------------------------

}

pCur.close();

}

}

// create an ArrayAdaptar from the String Array

dataAdapter = new MyCustomAdapter(MainActivity.this,

R.layout.blacklist_layout, phonebookList);

ListView listView = (ListView) findViewById(R.id.listView1);

// Assign adapter to ListView

listView.setAdapter(dataAdapter);

listView.setOnItemClickListener(new OnItemClickListener() {

public void onItemClick(AdapterView<?> parent,

}

});

}

}

});

return null;

}

@Override

protected void onPostExecute(Void result) {

if (mProgressDialog.isShowing()) {

mProgressDialog.dismiss();

}

}

@Override

protected void onPreExecute() {

ShowLoading();

}

@Override

protected void onProgressUpdate(Void... values) {

}

}

private void ShowLoading() {

mProgressDialog = new ProgressDialog(this);

mProgressDialog.setMessage("Loading Contacts ....");

mProgressDialog.setIndeterminate(false);

mProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);

mProgressDialog.setCancelable(false);

mProgressDialog.show();

}

}

• Add XML code in layout file, activity_main.xml

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:background="#fff"

    android:gravity="center"

    android:orientation="vertical" >

    <LinearLayout

        android:layout_width="fill_parent"

        android:layout_height="wrap_content"

        android:background="#000"

        android:gravity="center"

        android:orientation="horizontal" >

        <TextView

            style="@style/titlebar_textview"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_weight="0.5"

            android:textSize="18dp"

            android:text="Contacts" />

        <Button

            android:id="@+id/findSelected"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_margin="5dp"

            android:text="Save"

            android:textColor="#ffffff" />

    </LinearLayout>

    <ListView

        android:id="@+id/listView1"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent"

        android:divider="#BC0061"

        android:dividerHeight="2dp"

        android:background="@android:color/transparent"

        android:cacheColorHint="@android:color/transparent"

        android:padding="10dp" />

</LinearLayout>

After Added above code you will get error in some code but don't worry.Go to step 2 and add remaining code.

Go To next Step.

Contact List With Checkbox - Part 2

Got To Previous Step.

• Create new Class file, named Phonebook.java.

Phonebook.java

package com.example.contactlist;

import android.net.Uri;

public class Phonebook {

String number = null,name = null;

boolean isChecked = false;

Uri imgUri = null;

public Phonebook(String name,String number,boolean selected,Uri uri){

super();

this.name = name;

this.imgUri = uri;

this.isChecked = selected;

this.number = number;

}

public String getNumber() {

return number;

}

public void setNumber(String number) {

this.number = number;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public boolean isChecked() {

return isChecked;

}

public void setChecked(boolean isChecked) {

this.isChecked = isChecked;

}

public Uri getImgUri() {

return imgUri;

}

public void setImgUri(Uri imgUri) {

this.imgUri = imgUri;

}

}

• Create another class file,named Utils.java

Utils.java

import android.content.ContentResolver;

import android.content.ContentUris;

import android.content.Context;

import android.database.Cursor;

import android.net.Uri;

import android.provider.ContactsContract;

import android.provider.ContactsContract.PhoneLookup;

public class Utils {

public static String fetchContactIdFromPhoneNumber(String phoneNumber,Context context) {

// TODO Auto-generated method stub

Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI,

Uri.encode(phoneNumber));

Cursor cFetch = context.getContentResolver().query(uri,

new String[] { PhoneLookup.DISPLAY_NAME, PhoneLookup._ID },

null, null, null);

String contactId = "";

if (cFetch.moveToFirst()) {

cFetch.moveToFirst();

contactId = cFetch

.getString(cFetch.getColumnIndex(PhoneLookup._ID));

}

System.out.println(contactId);

return contactId;

}

public static Uri getPhotoUri(long contactId,Context context) {

ContentResolver contentResolver = context.getContentResolver();

try {

Cursor cursor = contentResolver

.query(ContactsContract.Data.CONTENT_URI,

null,

ContactsContract.Data.CONTACT_ID

+ "="

+ contactId

+ " AND "

+ ContactsContract.Data.MIMETYPE

+ "='"

+ ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE

+ "'", null, null);

if (cursor != null) {

if (!cursor.moveToFirst()) {

return null; // no photo

}

} else {

return null; // error in cursor process

}

} catch (Exception e) {

e.printStackTrace();

return null;

}

Uri person = ContentUris.withAppendedId(

ContactsContract.Contacts.CONTENT_URI, contactId);

return Uri.withAppendedPath(person,

ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);

}

}

• Create layout xml file in res/layout,named blacklist_layout.xml

blacklist_layout.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:gravity="center"

    android:orientation="horizontal"

    android:paddingLeft="3dip"

    android:paddingRight="3dip"

    android:paddingTop="3dip"

    android:paddingBottom="1dip" >

    <ImageView

        android:id="@+id/imgView"

        android:layout_width="70dp"

        android:layout_height="70dp"

        android:padding="5dp"

        android:src="@drawable/ic_launcher" />

    <LinearLayout

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_weight="1"

        android:gravity="left|center"

        android:orientation="vertical"

        android:padding="6dip" >

        <TextView

            android:id="@+id/tvName"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:text="Name"

            android:textStyle="bold"

            android:textSize="15dp"

            android:textColor="#000" />

        <TextView

            android:id="@+id/tvNumber"

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:text="Number"

            android:textSize="15dp"

            android:textColor="#000" />

    </LinearLayout>

    <CheckBox

        android:id="@+id/checkBox1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:focusable="false"

        android:focusableInTouchMode="false"

        android:gravity="right"

        android:textColor="#B40404" />

</LinearLayout>

• Last but not the least, Add following code in styles.xml file.

<style name="titlebar_textview">

        <item name="android:textColor">#fff</item>

        <item name="android:textStyle">bold</item>

        <item name="android:padding">10dp</item>

    </style>

    <ListView

        android:id="@+id/listView1"

        android:layout_width="fill_parent"

        android:layout_height="fill_parent" />

</LinearLayout>

• Add below code in MainActivity.java file.

MainActivity.java

public class MainActivity extends Activity {

MyCustomAdapter dataAdapter = null;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

// Generate list View from ArrayList

displayListView();

checkButtonClick();

}

private void displayListView() {

// Array list of countries

ArrayList<States> stateList = new ArrayList<States>();

States _states = new States("91", "India", false);

stateList.add(_states);

_states = new States("61", "Australia", true);

stateList.add(_states);

_states = new States("55", "Brazil", false);

stateList.add(_states);

_states = new States("86", "China", true);

stateList.add(_states);

_states = new States("49", "Germany", true);

stateList.add(_states);

_states = new States("36", "Hungary", false);

stateList.add(_states);

_states = new States("39", "Italy", false);

stateList.add(_states);

_states = new States("1", "US", false);

stateList.add(_states);

_states = new States("44", "UK", false);

stateList.add(_states);

// create an ArrayAdaptar from the String Array

dataAdapter = new MyCustomAdapter(this, R.layout.state_info, stateList);

ListView listView = (ListView) findViewById(R.id.listView1);

// Assign adapter to ListView

listView.setAdapter(dataAdapter);

listView.setOnItemClickListener(new OnItemClickListener() {

public void onItemClick(AdapterView<?> parent, View view,

int position, long id) {

// When clicked, show a toast with the TextView text

States state = (States) parent.getItemAtPosition(position);

Toast.makeText(getApplicationContext(),

"Clicked on : " + state.getName(), Toast.LENGTH_LONG)

.show();

}

});

}

private class MyCustomAdapter extends ArrayAdapter<States> {

private ArrayList<States> stateList;

public MyCustomAdapter(Context context, int textViewResourceId,

ArrayList<States> stateList) {

super(context, textViewResourceId, stateList);

this.stateList = new ArrayList<States>();

this.stateList.addAll(stateList);

}

private class ViewHolder {

TextView code;

CheckBox name;

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

ViewHolder holder = null;

Log.v("ConvertView", String.valueOf(position));

if (convertView == null) {

LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

convertView = vi.inflate(R.layout.state_info, null);

holder = new ViewHolder();

holder.code = (TextView) convertView.findViewById(R.id.code);

holder.name = (CheckBox) convertView

.findViewById(R.id.checkBox1);

convertView.setTag(holder);

holder.name.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

CheckBox cb = (CheckBox) v;

States _state = (States) cb.getTag();

Toast.makeText(

getApplicationContext(),

"Checkbox: " + cb.getText() + " -> "

+ cb.isChecked(), Toast.LENGTH_LONG)

.show();

_state.setSelected(cb.isChecked());

}

});

} else {

holder = (ViewHolder) convertView.getTag();

}

States state = stateList.get(position);

holder.code.setText(" (" + state.getCode() + ")");

holder.name.setText(state.getName());

holder.name.setChecked(state.isSelected());

holder.name.setTag(state);

return convertView;

}

}

private void checkButtonClick() {

Button myButton = (Button) findViewById(R.id.findSelected);

myButton.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

StringBuffer responseText = new StringBuffer();

responseText.append("Selected Countries are...\n");

ArrayList<States> stateList = dataAdapter.stateList;

for (int i = 0; i < stateList.size(); i++) {

States state = stateList.get(i);

if (state.isSelected()) {

responseText.append("\n" + state.getName());

}

}

Toast.makeText(getApplicationContext(), responseText,

Toast.LENGTH_LONG).show();

}

});

}

}

• Create new POJO java class,Which is used for getters and setters methods.Named it States.java. 

States.java

public class States {

String code = null;

String name = null;

boolean selected = false;

public States(String code, String name, boolean selected) {

super();

this.code = code;

this.name = name;

this.selected = selected;

}

public String getCode() {

return code;

}

public void setCode(String code) {

this.code = code;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public boolean isSelected() {

return selected;

}

public void setSelected(boolean selected) {

this.selected = selected;

}

}

• Create new XML layout file, which is used to integrate CheckBox and TextView in ListView.Named it state_info.xml.

state_info.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="wrap_content"

    android:orientation="vertical"

    android:padding="6dip" >

    <CheckBox

        android:id="@+id/checkBox1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"

        android:focusable="false"

        android:focusableInTouchMode="false"

        android:text="checkbox"

        android:textColor="#B40404" />

    <TextView

        android:id="@+id/code"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignBaseline="@id/checkBox1"

        android:layout_alignBottom="@id/checkBox1"

        android:layout_toRightOf="@id/checkBox1"

        android:text="textview"

        android:textColor="#ff000000" />
