获取用户通讯录信息的几种方式

前两种都是通过 Intent 来获取的

第一种

Intent localIntent = new Intent("android.intent.action.PICK");
localIntent.setType("vnd.android.cursor.dir/phone");
mActivity.startActivityForResult(localIntent, REQUEST_0);

选择了通讯录中的用户之后，会回到 OnActivityResult, 其中 disPlayName 和 phoneNumber 分别就是名字和电话

if (resultCode == RESULT_OK) {
                    Uri localUri = paramIntent.getData();
                    if (localUri != null) {
                        Cursor localCursor = getContentResolver().query(localUri, null, null, null, null);
                        if (localCursor != null)
                            while (true) {
                                if (!localCursor.moveToNext()) {
                                    DialogUtil.showTextDialog(mContext, this.disPlayName + "\n" + this.phoneNumber);
                                    super.onActivityResult(paramInt1, resultCode, paramIntent);
                                    return;
                                }
                                int i = localCursor.getColumnIndex("display_name");
                                if (i >= 0) {
                                    this.disPlayName = localCursor.getString(i);
                                    int j = localCursor.getColumnIndex("data1");
                                    if (j >= 0)
                                        this.phoneNumber = localCursor.getString(j);
                                }
                            }
                    }
                }

第二种

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, REQUEST_1);

同样调用到 OnActivityResult

if (resultCode == RESULT_OK) {
                    Uri uri = paramIntent.getData();
                    Cursor cursor = getContentResolver().query(uri, null, null, null, null);
                    cursor.moveToFirst();
                    String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    String number = getContactNumber(cursor);
                    DialogUtil.showTextDialog(mContext, contactName + "\n" + number);
                }

上面的 getCOntactNumber 方法在下面

private String getContactNumber(Cursor cursor) {
        String phoneNumber = null;
        int numberCount = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
        if (numberCount > 0) {
            int contactID = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts._ID));
            Cursor phoneNumberCursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactID, null, null);
            phoneNumberCursor.moveToFirst();
            phoneNumber = phoneNumberCursor.getString(phoneNumberCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            phoneNumberCursor.close();
            cursor.close();
            return phoneNumber;
        }
        return phoneNumber;
    }

第三种

第三种是我写的，通过获得所有联系人的信息，在 dialog 里面显示，然后让用户选择，选择了的会返回给程序，代码不算多，但是也不少，所以就直接下载代码看吧。下载在最下方
