1.在选择联系人方式网上也有很多案例 有的说是使用ContactsContract.CommonDataKinds.Phone.CONTENT_URI也有的说是使用ContactsContract.Contacts.CONTENT_URI其实这两种方式都可以使用 只不过ContactsContract.Contacts.CONTENT_URI这种方式需要多查询一遍

一、使用ContactsContract.CommonDataKinds.Phone.CONTENT_URI跳转到选择联系人

//跳转到选择联系人界面private fun openLinkman() {val intent = Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI)linkmanResultLauncher.launch(intent)}//联系人回调private val linkmanResultLauncher = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->if (result.resultCode == RESULT_OK) {val contactUri: Uri = result.data?.data ?: return@registerForActivityResultval projection: Array<String> = arrayOf(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER)contentResolver.query(contactUri, projection, null, null, null).use { cursor ->if (cursor != null && cursor.moveToFirst()) {val nameIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)val displayName = cursor.getString(nameIndex)val phoneIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)val phoneNumber = cursor.getString(phoneIndex)Log.e(TAG, "姓名:$displayName 手机号:$phoneNumber  count:${cursor.count}")}}}}

这里把openLinkman方法改成这样也是一样的

private fun openLinkman() {val intent = Intent(Intent.ACTION_PICK)intent.type = ContactsContract.CommonDataKinds.Phone.CONTENT_TYPElinkmanResultLauncher.launch(intent)
}

展示效果

二、使用ContactsContract.Contacts.CONTENT_URI跳转到选择联系人

private fun openLinkman() {val intent = Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI)linkmanResultLauncher2.launch(intent)
}//联系人回调private val linkmanResultLauncher2 = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->if (result.resultCode == RESULT_OK) {val contactUri: Uri = result.data?.data ?: return@registerForActivityResultcontentResolver.query(contactUri, null, null, null, null)?.use {cursor->if (cursor.moveToNext()){val nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)//获取联系人姓名val displayName = cursor.getString(nameIndex)var phoneNumber = ""//获取idval idIndex = cursor.getColumnIndex(ContactsContract.Contacts._ID)val id = cursor.getString(idIndex)//判断是否有手机号val hasPhoneIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.HAS_PHONE_NUMBER)val hasPhone = cursor.getString(hasPhoneIndex) //等于1就是有手机号if(hasPhone == "1"){//重新查询手机号contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,"${ContactsContract.CommonDataKinds.Phone.CONTACT_ID} = $id",null,null)?.use { phonesCursor->while (phonesCursor.moveToNext()){val phoneIndex = phonesCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)phoneNumber = phonesCursor.getString(phoneIndex)}}}Log.e(TAG, "姓名:$displayName  手机号:$phoneNumber")}}}}

展示效果

两则的区别

 1. 第一种联系人和姓名展示出来了 (不需要申请权限)2. 第二种只展示一个姓名  手机号又重新查询返回的 这种一个人又多个手机号的不能单独选\n择代码中是当前联系人的最后一个号码(需要申请android.permission.READ_CONTACTS权限)

这两种方式看需求使用就好了
