推荐答案
您不能使用Intent.ACTION_GET_CONTENT意向选择多个联系人.
您可以自己查询所有联系人及其电话号码，在ListView中将其显示给用户，并允许用户在您自己的应用程序中选择联系人.
You can't use the Intent.ACTION_GET_CONTENT intent to pick multiple contacts.
You can query for all contacts and their phone numbers yourself, display them in a ListView to the user, and allow the user to select the contacts within your own app.
要查询电话的联系人(如果您使用的是Contacts权限. >运行时权限)，您可以执行以下操作:
To query for the phone's contacts (requires the Contacts permission if you're using runtime-permissions) you can do this:
List<String> allPhones = new ArrayList<>();
// The Phone class should be imported from CommonDataKinds.Phone
Cursor cursor = getContentResolver().query(Phone.CONTENT_URI, new String[] { Phone.DISPLAY_NAME, Phone.NUMBER }, Phone.IN_VISIBLE_GROUP + "=1", null, Phone.TIMES_CONTACTED + " DESC");
while (cursor != null && cursor.moveToNext()) {
String name = cursor.getString(0);
String number = cursor.getString(1);
allPhones.add(name + " - " + number);
}
// display allPhones in a ListView on screen, and handle item clicks
