how to get contacts type in android?

问题

I want to retrieve both contacts name and their type in my layout.I am providing my activities and layout file.I am getting an invalid column type exception.any help would be greatly appreciable.thanks in advance.

TestActivity.class:

        package application.test;
        import android.app.ListActivity;

        import android.os.Bundle;
        import android.provider.ContactsContract;

Here's my Activity class I tested the code with. The layout is not important, as the contact info is printed on the standard output (look in DDMS).

import android.app.Activity;
import android.content.ContentResolver;
import android.content.Intent;
import android.database.Cursor;
import android.database.SQLException;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.provider.ContactsContract.CommonDataKinds.Phone;  
import android.provider.ContactsContract.Contacts.Data;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;

public final class ContactManager extends Activity {

public static final String TAG = "ContactManager";
@Override
public void onCreate(Bundle savedInstanceState)
{
    Log.v(TAG, "Activity State: onCreate()");
    super.onCreate(savedInstanceState);
    setContentView(R.layout.contact_manager);

    testGetContacts();
}


private void testGetContacts() { 

        ContentResolver cr = getContentResolver();

        String[] projection = new String[] { Data._ID,
                ContactsContract.Contacts.DISPLAY_NAME, Phone.TYPE}; 

        Cursor cur = cr.query(ContactsContract.Data.CONTENT_URI,
                projection, null, null, null); 


        if (cur != null && cur.moveToFirst()) { 

        try {

            int indexID =  cur.getColumnIndexOrThrow(ContactsContract.Contacts._ID);
            int indexName = cur.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME);
            int indexPhoneType = cur.getColumnIndexOrThrow(Phone.TYPE);

          while (cur.moveToNext()) {
              String id = cur.getString(indexID);    
              String name = cur.getString(indexName);  
              String phoneType =  cur.getString(indexPhoneType);

              System.out.println(id + "\n");
              System.out.println(name + "\n");
              System.out.println(phoneType + "\n");
          }

        } catch (SQLException sqle) {
           //handle exception here - like missing column name!         
        } finally { //close your cursor if it's not needed!
         if (!cur.isClosed()) {
             cur.close();
         }     
     }
    }

}

}

Suggestions for better code:

0) Add projection to your code => getting all columns is inefficient

    String[] projection = new String[] { ContactsContract.Contacts._ID,
                ContactsContract.Contacts.DISPLAY_NAME,ContactsContract.PhoneLookup.TYPE};

And than add the projection to your query:

Cursor cur = cr.query(ContactsContract.Data.CONTENT_URI,
                        projection, null, null, null);

1) In your loop, your getting column index on every iteration. That's not necessary move the cur.getColumnIndex out of the loop.

2) When working with cursor, you may supplement the for-loop with while-condition loop. Here's a suggestion of impl. of your method getContacts():

  // A list of providers imports used!
 import android.provider.ContactsContract;
 import android.provider.ContactsContract.CommonDataKinds.Phone;
 import android.provider.ContactsContract.Contacts.Data;

 public void getContacts(){
         ContentResolver cr = getContentResolver();

                   String[] projection = new String[] { Data._ID,
                ContactsContract.Contacts.DISPLAY_NAME, Phone.TYPE}; 

        Cursor cur = cr.query(ContactsContract.Data.CONTENT_URI,
                projection, null, null, null); 
         // don't use this ContentProvider
        // Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
                    //    projection, null, null, null);


         if (cur != null && cur.moveToFirst()) { 

         try {

              int indexID =  cur.getColumnIndexOrThrow(ContactsContract.Contacts._ID);
              int indexName = cur.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME);
              int indexPhoneType = cur.getColumnIndexOrThrow(Phone.TYPE);

           while (cur.moveToNext()) {
            //do your logic here;           
              String id = cur.getString(indexID);    
              String name = cur.getString(indexName);  
              String phoneType =  cur.getString(indexPhoneType);
           }

         } catch (SQLException sqle) {
            //handle exception here - like missing column name!         
         } finally { //close your cursor if it's not needed!
          if (!cur.isClosed()) {
              cur.close();
          }     
      }
     }
   }

EDIT:

Use this imports:

 import android.provider.ContactsContract;
 import android.provider.ContactsContract.CommonDataKinds.Phone;
 import android.provider.ContactsContract.Contacts.Data;

Use this projection

   String[] projection = new String[] { ContactsContract.Contacts._ID,
            ContactsContract.Contacts.DISPLAY_NAME,ContactsContract.PhoneLookup.TYPE};

Use this Query:

   Crsor cur = cr.query(ContactsContract.Data.CONTENT_URI,
                projection, null, null, null); 

Use this column names:

              int indexID =  cur.getColumnIndexOrThrow(ContactsContract.Contacts._ID);
              int indexName = cur.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME);
              int indexPhoneType = cur.getColumnIndexOrThrow(Phone.TYPE);
