Step 1: Create a new project in Android Studio.
When you are creating new project, select empty activity as default activity.
Step 2: Updating AndroidManifest.xml file
add required permissions between <manifest>….</manifest> tag.
<uses-permission android:name="android.permission.READ_CONTACTS" />
Note: If you are targeting SDK version above 22 (Above Lollipop) then you need to ask a user for granting runtime permissions. Check marshmallow runtime permission for more information.
Final code for AndroidManifest.xml file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.parsaniahardik.kotlin_contact_demo">
<uses-permission android:name="android.permission.READ_CONTACTS" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Step 3: Updating activity_main.xml file
Copy and paste below source code in activity_main.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="10dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="10dp"
tools:context="com.example.parsaniahardik.kotlin_contact_demo.MainActivity">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="@+id/tvname"
android:textColor="#000"
android:text="Name:"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="@+id/tvphone"
android:textColor="#000"
android:text="Phone:"/>

<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:id="@+id/btn"
android:text="Select contact" />
</LinearLayout>
Step 4: Preparing MainActivity.kt class
Add following source code in MainActivity.kt class
import android.app.Activity
import android.content.Intent
import android.database.Cursor
import android.net.Uri
import android.provider.ContactsContract
import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import android.view.View
import android.widget.Button
import android.widget.TextView
class MainActivity : AppCompatActivity() {
private var btn: Button? = null
private var tvname: TextView? = null
private var tvphone: TextView? = null
private var tvmail: TextView? = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
btn = findViewById(R.id.btn) as Button
tvname = findViewById(R.id.tvname) as TextView
tvphone = findViewById(R.id.tvphone) as TextView
tvmail = findViewById(R.id.tvmail) as TextView
btn!!.setOnClickListener {
val intent = Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI)
startActivityForResult(intent, 1)
}
}
public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) {
if (resultCode == Activity.RESULT_OK) {
val contactData = data.data
val c = contentResolver.query(contactData!!, null, null, null, null)
if (c!!.moveToFirst()) {
var phoneNumber = ""
var emailAddress = ""
val name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME))
val contactId = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID))
//http://stackoverflow.com/questions/866769/how-to-call-android-contacts-list our upvoted answer
var hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))
if (hasPhone.equals("1", ignoreCase = true))
hasPhone = "true"
else
hasPhone = "false"
if (java.lang.Boolean.parseBoolean(hasPhone)) {
val phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null)
while (phones!!.moveToNext()) {
phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
}
phones.close()
}
// Find Email Addresses
val emails = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null)
while (emails!!.moveToNext()) {
emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA))
}
emails.close()
//mainActivity.onBackPressed();
// Toast.makeText(mainactivity, "go go go", Toast.LENGTH_SHORT).show();
tvname!!.text = "Name: " + name
tvphone!!.text = "Phone: " + phoneNumber
tvmail!!.text = "Email: " + emailAddress
Log.d("curs", "$name num$phoneNumber mail$emailAddress")
}
c.close()
}
}
}
Step 5: Description of MainActivity.kt
Following source code will open contact list on button click.
btn!!.setOnClickListener {
val intent = Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI)
startActivityForResult(intent, 1)
}
After clicking on contact list item, onActivityResult() method is called.
Below line will get name of contact
val name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME))
Below source code will check whether contact has a phone number or not.
var hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))
if (hasPhone.equals("1", ignoreCase = true))
hasPhone = "true"
else
hasPhone = "false"
If contact has phone number, then it will be got by following
if (java.lang.Boolean.parseBoolean(hasPhone)) {
val phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null)
while (phones!!.moveToNext()) {
phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
}
phones.close()
}
Following will take the Email address.
// Find Email Addresses
val emails = contentResolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null)
while (emails!!.moveToNext()) {
emailAddress = emails.getString(emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA))
}
emails.close()
Then finally, all text are set
tvname!!.text = "Name: " + name tvphone!!.text = "Phone: " + phoneNumber tvmail!!.text = "Email: " + emailAddress
