Question

I am trying to create a program. There is also a function I want to ask. I have a button and a textview. I want that when I press the button, my phonebook is opened so that I could select a contact number. After finished, the selected contact number will be displayed in the textview. Currently, I have no idea how to do that.

Answer 1

on the onClick call this..

Intent intent = new Intent(Intent.ACTION_PICK,Uri.parse("content://contacts/"));
            startActivityForResult(intent, 1);

override the onActivityResult method, use Cursor to move to the selected contact and display it in your textview

This could look something like this…

if (resultCode == Activity.RESULT_OK) 
{
    Uri contactData = data.getData();
     Cursor c = managedQuery(contactData, null, null, null, null);
     c.moveToFirst();
     String name;
     name = c.getString(c.getColumnIndexOrThrow(People.NAME));
    TextView tv;
    tv = (TextView)findViewById(R.id.selected_contact_textview);
    tv.setText(name);
}
