### Anddroid调用系统自带的联系人 ###

在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。

#### 2.0之前取联系人列表的方式： ####

##### 1.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     );

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     );

##### 2.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;  
            }  
        }

#### 2.0之后取联系人列表的方式： ####

##### 1.声明意图 #####

方式一

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
    startActivityForResult(intent, PICK_CONTACT);

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);

##### 2.实现onActivityResult #####

private static final int PICK_CONTACT = 0;  
     @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 = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));  
                            String contactId = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));  
                            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();  
                            } 
                        }  
                    }
