Open device contacts list at button click event

Question

How can i open Android device contacts list at button click event.

Answer 1

Declare Some variables. Create a method & handle the events.

private static final int CONTACT_PICKER_RESULT = 1001;
private static final String DEBUG_TAG = "Contact List";
private static final int RESULT_OK = -1;

// a method to open your contact list
private void openContactList() {

    Intent it = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
    startActivityForResult(it, CONTACT_PICKER_RESULT);

}

// handle after selecting a contact from the list
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        switch (requestCode) {
        case CONTACT_PICKER_RESULT:
            // handle contact results
            Log.w(DEBUG_TAG, "Warning: activity result is ok!");
            break;
        }
    } else {
        // gracefully handle failure
        Log.w(DEBUG_TAG, "Warning: activity result not ok");
    }
}
