发送短信到特定的联系人（WhatsApp的） [英] Send text to specific contact (whatsapp)

问题描述

我想知道我可以发短信到特定的WhatsApp的接触。我发现了一些code，以查看特定的联系人，但不发送数据。

 光标C = getContentResolver（）查询（ContactsContract.Data.CONTENT_URI，
    新的String [] {} ContactsContract.Contacts.Data._ID，ContactsContract.Data.DATA1 +=？，
    新的String [] {ID}，NULL）;
c.moveToFirst（）;
意图I =新的意图（Intent.ACTION_VIEW，Uri.parse（内容：//com.android.contacts/data/+ c.getString（0）））;

startActivity（ⅰ）;
c.close（）;
 

这工作正常查看WhatsApp的接触，但我怎么能现在添加一些文字？或者未在WhatsApp的开发者实现这类的API的？

解决方案

我想答案是你的问题的结构和这个答案在这里：的 http://stackoverflow.com/a/15931345/734687 所以我想尝试以下code：

1. 变化ACTION_VIEW到ACTION_SENDTO
2. 将开放的我们像你一样
3. 将包WhatsApp的

意向书我=新的意图（Intent.ACTION_SENDTO，Uri.parse（内容：//com.android.contacts/数据/+ c.getString（0）））; i.setType（text / plain的）; i.setPackage（com.whatsapp）; //这样只有WhatsApp的反应，而不是选择器 i.putExtra（Intent.EXTRA_SUBJECT，主题）; i.putExtra（Intent.EXTRA_TEXT，我的身体。）; startActivity（ⅰ）;

我看着到WhatsApp的清单，看见ACTION_SEND注册到活动 ContactPicker ，这样就不会帮你。然而ACTION_SENDTO注册到活动 com.whatsapp.Conversation 这听起来更好地满足您的问题。

WhatsApp的可作为替代发送短信的工作，所以它应该工作一样的短信。如果没有指定所需的应用程序（通过 setPackage ）的Andr​​oid显示应用程序管理器。 Thererfor你应该看看code通过故意发送短信，然后提供额外的软件包的信息。

开放的URI = Uri.parse（smsto：+ smsNumber）; 意图I =新的意图（Intent.ACTION_SENDTO，URI）; i.putExtra（sms_body，smsText）; i.setPackage（com.whatsapp）; startActivity（ⅰ）;

第一次尝试，以取代意图 ACTION_SEND 到 ACTION_SENDTO 。如果这样做的工作比提供的附加额外的 sms_body 。如果这样做的工作比试图改变URI。

更新 我试图解决这个我自己，没能找到解决的办法。 WhatsApp的是开放的聊天记录，但不采取文字和发送。看来，这个功能只是没有实现。

I wanted to know how I can send text to a specific whatsapp contact. I found some code to view a specific contact, but not to send data.

Cursor c = getContentResolver().query(ContactsContract.Data.CONTENT_URI,
    new String[] { ContactsContract.Contacts.Data._ID }, ContactsContract.Data.DATA1 + "=?",
    new String[] { id }, null);
c.moveToFirst();
Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));

startActivity(i);
c.close();

This works fine for viewing a whatsapp-contact, but how can I add some text now? Or didn't the Whatsapp-developer implement such kind of an api?

解决方案

I think the answer is a mix of your question and this answer here: http://stackoverflow.com/a/15931345/734687 So I would try the following code:

1. change ACTION_VIEW to ACTION_SENDTO
2. set the Uri as you did
3. set the package to whatsapp

Intent i = new Intent(Intent.ACTION_SENDTO, Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
i.setType("text/plain");
i.setPackage("com.whatsapp");           // so that only Whatsapp reacts and not the chooser
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "I'm the body.");
startActivity(i);

I looked into the Whatsapp manifest and saw that ACTION_SEND is registered to the activity ContactPicker, so that will not help you. However ACTION_SENDTO is registered to the activity com.whatsapp.Conversation which sounds more adequate for your problem.

Whatsapp can work as a replacement for sending SMS, so it should work like SMS. When you do not specify the desired application (via setPackage) Android displays the application picker. Thererfor you should just look at the code for sending SMS via intent and then provide the additional package information.

Uri uri = Uri.parse("smsto:" + smsNumber);
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra("sms_body", smsText);  
i.setPackage("com.whatsapp");  
startActivity(i);

First try just to replace the intent ACTION_SEND to ACTION_SENDTO . If this does not work than provide the additional extra sms_body. If this does not work than try to change the uri.

Update I tried to solve this myself and was not able to find a solution. Whatsapp is opening the chat history, but doesn't take the text and send it. It seems that this functionality is just not implemented.
