android - 从android中的firebase数据库向多个号码发送消息
问题描述
我想从移动设备向多个联系人发送消息。流程是我正在创建一个血库应用程序，在该应用程序中，当用户请求血液时，我会在 firebase 回收器视图中向他显示所有具有匹配血型的用户列表。在回收器中，我正在向他展示单击任何所需过程的任何图标时，带有 2 个呼叫图标和消息的用户名称都可以正常工作。我想要的是，当用户在向他显示匹配血型的人列表后请求血液时，我应该务实地向匹配血型列表中显示的所有用户发送消息。我查看了多个问题并尝试了答案，但没有成功实现它。
在此我尝试了堆栈溢出的另一种解决方案，但结果相同，它没有发送消息

注意：我正在尝试将消息发送给多个用户而不是单个用户
解决方案
我为此找到了 2 个解决方案。
1-从firebase获取数据时，我通过将消息代码放在获取用户详细信息的位置立即向用户发送消息（它将获得1个号码并向其发送消息，然后是另一个，然后是另一个，之后它将设置适配器是的，在此期间我会显示一些进度条或其他东西）。
2-我可以在我的应用程序中做的另一件事是在列表下方显示向用户发送消息的按钮，并将所有联系号码存储到数组列表中，同时获取用户数据，当用户单击该按钮时，将消息发送给所有用户这些号码我们已经进入arrayList。
像这样 ：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_donar_list);
getView();
showRecyclerView();
contactNumber.addAll(numbersSet);
}
private void showRecyclerView() {
adapter = new FirebaseRecyclerAdapter<Profiles, DonarViewHolder>(model) {
@Override
protected void onBindViewHolder(@NonNull DonarViewHolder holder, int position, @NonNull Profiles profiles) {
String number = profiles.getMobile_number();
numbersSet.add(profiles.getMobile_number());
ArrayList<String> bloodGroupMatched = new ArrayList<>();
bloodGroupMatched.addAll(profiles.getMatched_bloodGroups());
if (bloodGroupMatched.contains(bloodGroup)) {
holder.name.setText(profiles.getName());
holder.itemView.setVisibility(View.VISIBLE);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(10, 5, 5, 10);
holder.itemView.setLayoutParams(params);
} else {
holder.itemView.setVisibility(View.GONE);
holder.itemView.setLayoutParams(new RecyclerView.LayoutParams(0, 0));
}
holder.call.setOnClickListener(v -> {
boolean conditionCheck = true;
Intent callIntent = new Intent(Intent.ACTION_DIAL);
callIntent.setData(Uri.parse("tel:" + number));
if (ActivityCompat.checkSelfPermission(DonarList.this,
Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(DonarList.this,
new String[]{Manifest.permission.CALL_PHONE}, 1);
}
startActivity(callIntent);
});
holder.msg.setOnClickListener(v -> {
Intent smsIntent = new Intent(Intent.ACTION_SENDTO);
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.setData(Uri.parse("sms:" + number));
if (ActivityCompat.checkSelfPermission(DonarList.this,
Manifest.permission.SEND_SMS) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(DonarList.this,
new String[]{Manifest.permission.SEND_SMS}, MY_PERMISSIONS_REQUEST_SEND_SMS);
} else {
startActivity(smsIntent);
}
});
}
