Step 4: Preparing MainActivity.java class
Add following source code in MainActivity.java class
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 |
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; public class MainActivity extends AppCompatActivity { private Button btn; private TextView tvname, tvphone,tvmail; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btn = (Button) findViewById(R.id.btn); tvname = (TextView) findViewById(R.id.tvname); tvphone = (TextView) findViewById(R.id.tvphone); tvmail = (TextView) findViewById(R.id.tvmail); btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); startActivityForResult(intent, 1); } }); } @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == Activity.RESULT_OK) { Uri contactData = data.getData(); Cursor c = getContentResolver().query(contactData, null, null, null, null); if (c.moveToFirst()) { String phoneNumber="",emailAddress=""; String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); String contactId = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID)); //http://stackoverflow.com/questions/866769/how-to-call-android-contacts-list our upvoted answer String hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); if ( hasPhone.equalsIgnoreCase("1")) hasPhone = "true"; else hasPhone = "false" ; if (Boolean.parseBoolean(hasPhone)) { Cursor phones = getContentResolver().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 Cursor emails = getContentResolver().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.setText("Name: "+name); tvphone.setText("Phone: "+phoneNumber); tvmail.setText("Email: "+emailAddress); Log.d("curs", name + " num" + phoneNumber + " " + "mail" + emailAddress); } c.close(); } } } |
Step 5: Description of MainActivity.java
Following source code will open contact list on button click.
|
1 2 3 4 5 6 7 |
btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new 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
|
1 |
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); |
Below source code will check whether contact has a phone number or not.
|
1 2 3 4 5 6 |
String hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); if ( hasPhone.equalsIgnoreCase("1")) hasPhone = "true"; else hasPhone = "false" ; |
If contact has phone number, then it will be got by following
|
1 2 3 4 5 6 7 8 9 |
if (Boolean.parseBoolean(hasPhone)) { Cursor phones = getContentResolver().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 source code will take the Email address.
|
1 2 3 4 5 6 7 |
// Find Email Addresses Cursor emails = getContentResolver().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 in respected textviews
|
1 2 3 |
tvname.setText("Name: "+name); tvphone.setText("Phone: "+phoneNumber); tvmail.setText("Email: "+emailAddress); |
