android应用程序的开发中,经常要实现的一个功能是调用系统自带的联系人界面,做到选择人之后,取得相应的名称和号码,并返回。

android2.0前后实现方式上也有一定的差别:主要是2.0及以上版本联系人API发生了变化,由原来的Contacts变成了ContactsContract。

(一) 2.0之前取联系人列表的方式
声明意图方式一
Intent intent = new Intent();
intent.setAction(Intent.ACTION_PICK);
intent.setData(Contacts.People.CONTENT_URI);
startActivityForResult(intent,  
 
PICK_CONTACT
  
 );
声明意图方式二
Intent intent  = new Intent(Intent.ACTION_PICK);
intent.setType("Contacts.People.CONTENT_TYPE");//vnd.android.cursor.dir/person
startActivityForResult(intent,  
 
PICK_CONTACT
  
 );
实现onActivityResult
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case  
 
PICK_CONTACT
  
 :
                if (data == null) {
                    return;
                }
                Uri uri = data.getData();
                Cursor cursor = getContentResolver().query(uri, null, null, null, null);
                cursor.moveToFirst();
                String number = cursor.getString(cursor.getColumnIndexOrThrow(Phones.NUMBER));
                Log.d(TAG, "number" + number);
                mContactText.setText(number);
                mContactText.setSelection(number.length());
                break;
            
            default:
                break;
        }
    } 
 
(二) 2.0之后取联系人列表的方式
声明意图方式一
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);
声明意图方式二
Intent intent = new Intent(Intent.ACTION_PICK);  
      intent.setType(ContactsContract.Contacts.CONTENT_TYPE);//vnd.android.cursor.dir/contact
startActivityForResult(intent, PICK_CONTACT);
实现onActivityResult
@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
  super.onActivityResult(reqCode, resultCode, data);
 
  switch (reqCode) {
    case (PICK_CONTACT) :
      if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  managedQuery(contactData, null, null, null, null);
        if (c.moveToFirst()) {
          String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
          String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
          String phoneNumber = null;
          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();
          }
        }
      }
      break;
  }
}
