以编程方式将文本发送到特定联系人（whatsapp）

Question

我想知道如何将文本发送到特定的WhatsApp联系人。我找到了一些代码来查看特定联系人，但不发送数据。

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();

这适用于查看whatsapp-contact，但我现在如何添加一些文本？或者Whatsapp开发人员没有实现这样的api？

Answer 1

我认为答案是你的问题和这个答案的混合：https://stackoverflow.com/a/15931345/734687所以我会尝试以下代码：

将ACTION_VIEW更改为ACTION_SENDTO
像你一样设置Uri
将包设置为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);

我查看了Whatsapp清单，发现ACTION_SEND已注册到活动ContactPicker，所以这对你没有帮助。但是，ACTION_SENDTO已注册到活动com.whatsapp.Conversation，这听起来更适合您的问题。

Whatsapp可以作为发送短信的替代品，所以它应该像短信一样工作。如果您未指定所需的应用程序（通过qazxswpoi），Android将显示应用程序选择器。因此，您应该查看通过意图发送SMS的代码，然后提供其他包信息。

setPackage

首先尝试将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);替换为ACTION_SEND。如果这不起作用，而不是提供额外的额外ACTION_SENDTO。如果这不起作用，请尝试更改uri。

更新我试图自己解决这个问题，但无法找到解决方案。 Whatsapp打开聊天记录，但不接收文本并发送。似乎这个功能没有实现。

Answer 2

现在可以通过See also the documentation of WhatsApp实现。只有企业可以申请使用它。这是直接向电话号码发送消息的唯一方法，无需任何人为干预。

发送正常消息是免费的。看起来您需要在服务器上托管MySQL数据库和WhatsApp Business Client。

Answer 3

检查这个答案。这里你的号码以“91 **********”开头。

WhatsApp Business API

Answer 4

试试这个，为我工作！。只是使用意图

Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.setAction(Intent.ACTION_SEND);

sendIntent.setType("text/plain");                    
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");                   sendIntent.putExtra("jid",PhoneNumberUtils.stripSeparators("91**********")                   + "@s.whatsapp.net");                    
sendIntent.setPackage("com.whatsapp");                    
startActivity(sendIntent);

构建whatsapp网址。在whatsapp电话号码Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(whatsappUrl())); startActivity(intent);中添加国家代码

https://countrycode.org/

Answer 5

这将首先搜索指定的联系人，然后打开聊天窗口。

注意：phone_number和str是变量。

public static String whatsappUrl(){

    final String BASE_URL = "https://api.whatsapp.com/";
    final String WHATSAPP_PHONE_NUMBER = "628123232323";    //'62' is country code for Indonesia
    final String PARAM_PHONE_NUMBER = "phone";
    final String PARAM_TEXT = "text";
    final String TEXT_VALUE = "Hello, How are you ?";

    String newUrl = BASE_URL + "send";

    Uri builtUri = Uri.parse(newUrl).buildUpon()
            .appendQueryParameter(PARAM_PHONE_NUMBER, WHATSAPP_PHONE_NUMBER)
            .appendQueryParameter(PARAM_TEXT, TEXT_VALUE)
            .build();

    return buildUrl(builtUri).toString();
}

public static URL buildUrl(Uri myUri){

    URL finalUrl = null;
    try {
        finalUrl = new URL(myUri.toString());
    } catch (MalformedURLException e) {
        e.printStackTrace();

    }
    return finalUrl;
}

Answer 6

Uri mUri = Uri.parse("https://api.whatsapp.com/send?
phone=" + phone_no + "&text=" + str);
Intent mIntent = new Intent("android.intent.action.VIEW", mUri);
mIntent.setPackage("com.whatsapp");
startActivity(mIntent);

我已经做了！

sms_body

Answer 12

我找到了正确的方法，这很简单，你只需要阅读这篇文章：private void openWhatsApp() { String smsNumber = "7****"; // E164 format without '+' sign Intent sendIntent = new Intent(Intent.ACTION_SEND); sendIntent.setType("text/plain"); sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send."); sendIntent.putExtra("jid", smsNumber + "@s.whatsapp.net"); //phone number without "+" prefix sendIntent.setPackage("com.whatsapp"); if (intent.resolveActivity(getActivity().getPackageManager()) == null) { Toast.makeText(this, "Error/n" + e.toString(), Toast.LENGTH_SHORT).show(); return; } startActivity(sendIntent); }

源代码：http://howdygeeks.com/send-whatsapp-message-unsaved-number-android/和phone都是message。

String

请享用！

Answer 13

这种方法也适用于WhatsApp Business应用程序！

将包名更改为sendIntent.setPackage（“com.whatsapp.w4b”）;为WhatsApp业务。

非常好的黑客Rishabh，非常感谢，自从过去3年以来我一直在寻找这个解决方案。

根据Rishabh Maurya上面的回答，我已经实现了这个代码，它在WhatsApp上的文本和图像共享都很好。

请注意，在这两种情况下，它都会打开一个whatsapp对话（如果toNumber存在于用户whatsapp联系人列表中），但用户必须单击“发送”按钮才能完成操作。这意味着它有助于跳过联系人选择步骤。

用于短信

    PackageManager packageManager = context.getPackageManager();
    Intent i = new Intent(Intent.ACTION_VIEW);

    try {
        String url = "https://api.whatsapp.com/send?phone="+ phone +"&text=" + URLEncoder.encode(message, "UTF-8");
        i.setPackage("com.whatsapp");
        i.setData(Uri.parse(url));
        if (i.resolveActivity(packageManager) != null) {
            context.startActivity(i);
        }
    } catch (Exception e){
        e.printStackTrace();
    }

用于共享图像

String toNumber = "+91 98765 43210"; // contains spaces.
toNumber = toNumber.replace("+", "").replace(" ", "");

Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.putExtra("jid", toNumber + "@s.whatsapp.net");
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("text/plain");
startActivity(sendIntent);

享受WhatsApping！

Answer 14

它允许您为您尝试与之通信的特定用户打开WhatsApp对话屏幕：

String toNumber = "+91 98765 43210"; // contains spaces.
toNumber = toNumber.replace("+", "").replace(" ", "");

Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(imageFile));
sendIntent.putExtra("jid", toNumber + "@s.whatsapp.net");
sendIntent.putExtra(Intent.EXTRA_TEXT, message);
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("image/png");
context.startActivity(sendIntent);

Answer 15

看看我的答案：private void openWhatsApp() { String smsNumber = "91XXXXXXXX20"; boolean isWhatsappInstalled = whatsappInstalledOrNot("com.whatsapp"); if (isWhatsappInstalled) { Intent sendIntent = new Intent("android.intent.action.MAIN"); sendIntent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.Conversation")); sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators(smsNumber) + "@s.whatsapp.net");//phone number without "+" prefix startActivity(sendIntent); } else { Uri uri = Uri.parse("market://details?id=com.whatsapp"); Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri); Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT).show(); startActivity(goToMarket); } } private boolean whatsappInstalledOrNot(String uri) { PackageManager pm = getPackageManager(); boolean app_installed = false; try { pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES); app_installed = true; } catch (PackageManager.NameNotFoundException e) { app_installed = false; } return app_installed; }

https://stackoverflow.com/a/40285262/5879376

Answer 16

这将首先搜索指定的联系人，然后打开聊天窗口。如果没有安装WhatsApp，那么try-catch块处理这个。

 Intent sendIntent = new Intent("android.intent.action.MAIN");
 sendIntent.setComponent(new  ComponentName("com.whatsapp","com.whatsapp.Conversation"));
 sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators("YOUR_PHONE_NUMBER")+"@s.whatsapp.net");//phone number without "+" prefix

 startActivity(sendIntent);

Answer 17

Whatsapp有自己的API

 String digits = "\\d+";
    Sring mob_num = 987654321;     
    if (mob_num.matches(digits)) 
            {
        try {
              /linking for whatsapp
              Uri uri = Uri.parse("whatsapp://send?phone=+91" + mob_num);
              Intent i = new Intent(Intent.ACTION_VIEW, uri);
              startActivity(i);
            }
            catch (ActivityNotFoundException e){
                    e.printStackTrace();
                    Toast.makeText(this, "WhatsApp not installed.", Toast.LENGTH_SHORT).show();
            }
        }

为活动添加的代码更新检查是否可用。

见Intent sendIntent = new Intent("android.intent.action.MAIN"); sendIntent.setAction(Intent.ACTION_VIEW); sendIntent.setPackage("com.whatsapp"); String url = "https://api.whatsapp.com/send?phone=" + "Phone with international format" + "&text=" + "your message"; sendIntent.setData(Uri.parse(url)); if(sendIntent.resolveActivity(context.getPackageManager()) != null){ startActivity(sendIntent); }

Answer 18

这是最短的方式

this documentation

String mPhoneNumber = "+972505555555"; mPhoneNumber = mPhoneNumber.replaceAll("+", "").replaceAll(" ", "").replaceAll("-",""); String mMessage = "Hello world"; String mSendToWhatsApp = "https://wa.me/" + mPhoneNumber + "?text="+mMessage; startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse( mSendToWhatsApp )));
