我正在开发一个Android应用程序，我需要向WhatsApp的特定联系人发送消息。 我试过这段代码：

Uri mUri = Uri.parse("smsto:+999999999");
Intent mIntent = new Intent(Intent.ACTION_SENDTO, mUri);
mIntent.setPackage("com.whatsapp");
mIntent.putExtra("sms_body", "The text goes here");
mIntent.putExtra("chat",true);
startActivity(mIntent);

问题是WhatsApp没有收到参数“sms_body”，但选择了联系人。

有一种方法。确保您提供的联系人必须作为意向字符串传递，而不带前缀“+”。国家/地区代码应作为电话号码的前缀附加。

例如：'+ 918547264285'应作为'918547264285'传递。这里的'91'开头是国家代码。

注意：将“YOUR_PHONE_NUMBER”替换为您要向其发送消息的联系人。

以下是摘录：

 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");
 startActivity(sendIntent);

这种新方法，通过Android中的whatsapp向特定联系人发送消息。有关详细信息，请查看here 

            Intent sendIntent = new Intent();
            sendIntent.setAction(Intent.ACTION_VIEW);
            String url = "https://api.whatsapp.com/send?phone=" + number + "&text=" + path;
            sendIntent.setData(Uri.parse(url));

很棒的黑客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，它对WhatsApp上的文本和图像共享都很好。我已经在我的Android应用程序中发布了这个，所以如果你想看到它，请试试我的应用Bill Book

请注意，在这两种情况下，它都会打开一个whatsapp会话（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

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);

用于分享图像

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);

享受WhatsApping！

您可以使用以下代码：

 Intent sendIntent = new Intent("android.intent.action.MAIN");
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setPackage("com.whatsapp");
sendIntent.setType("text/plain");
sendIntent.putExtra("jid", "9194******22" + "@s.whatsapp.net");// here 91 is country code
sendIntent.putExtra(Intent.EXTRA_TEXT, "Demo test message");
startActivity(sendIntent);

这是通过Whatsapp将邮件发送到特定号码或未保存号码的最佳方法

private void openWhatsApp() {
    String smsNumber = "252634651588";
    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(getContext(), "WhatsApp not Installed",
                Toast.LENGTH_SHORT).show();
        startActivity(goToMarket);
    }
}

private boolean whatsappInstalledOrNot(String uri) {
    PackageManager pm = Objects.requireNonNull(getContext()).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;
}

这对我有用。

参数＆＃39; body＆＃39; whatsapp app不会变红，使用＆＃39; Intent.EXTRA_TEXT＆＃39;代替。

设置＆＃39; phoneNumber＆＃39;您指定要在whatsapp中打开的联系人。

[
    {
      "id":"Item 1",
      "name": "Item 1 Name",
      "image": "./item1.jpg",
      "number": "Number 1"
    },
    {
      "id":"Item 2",
      "name": "Item 2 Name",
      "image": "./item2.jpg",
      "number": "Number 2"
    },
    ...,
    ...
    ]

我们可以分享/发送消息到什么应用程序。以下是在Whats-app

上发送短信的示例代码
  
      
  1. 单个用户
    2.    
private void shareToOneWhatsAppUser(String message) {

    /**
     * NOTE:
     * Message is shared with only one user at a time. and to navigate back to main application user need to click back button
     */
    Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
    whatsappIntent.setType("text/plain");
    whatsappIntent.setPackage("com.whatsapp");
    whatsappIntent.putExtra(Intent.EXTRA_TEXT, message);

    //Directly send to specific mobile number...
    String smsNumber = "919900990099";//Number without with country code and without '+' prifix
    whatsappIntent.putExtra("jid", smsNumber + "@s.whatsapp.net"); //phone number without "+" prefix

    if (whatsappIntent.resolveActivity(getPackageManager()) == null) {
        Toast.makeText(MainActivity.this, "Whatsapp not installed.", Toast.LENGTH_SHORT).show();
        return;
    }

    startActivity(whatsappIntent);
}
  
      
  1. 多个用户
    2.    
private void shareToMultipleWhatsAppUser(String message) {

    /**
     * NOTE:
     *
     * If want to send same message to multiple users then have to select the user to whom you want to share the message & then click send.
     * User navigate back to main Application once he/she select all desired persons and click send button.
     * No need to click Back Button!
     */

    Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
    whatsappIntent.setType("text/plain");
    whatsappIntent.setPackage("com.whatsapp");
    whatsappIntent.putExtra(Intent.EXTRA_TEXT, message);

    if (whatsappIntent.resolveActivity(getPackageManager()) == null) {
        Toast.makeText(MainActivity.this, "Whatsapp not installed.", Toast.LENGTH_SHORT).show();
        return;
    }

    startActivity(whatsappIntent);
}
  
    

实现相同的另一种方式

  
private void shareDirecctToSingleWhatsAppUser(String message) {

    /**
     * NOTE:
     * Message is shared with only one user at a time. and to navigate back to main application user need to click back button
     */

    //Directly send to specific mobile number...
    String smsNumber = "919900000000";//Intended user`s mobile number with country code & with out '+'

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

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

尝试此代码

Uri uri = Uri.parse("smsto:" + "+6281122xxx");
Intent i = new Intent(Intent.ACTION_SENDTO, uri);
i.putExtra(Intent.EXTRA_TEXT, getResources().getString(R.string.default_message_wa));
i.setPackage("com.whatsapp");
startActivity(Intent.createChooser(i, ""));

您不能像这样将字符串直接放在putExtra上

i.putExtra(Intent.EXTRA_TEXT, "YOUR TEXT");

更改代码并从这样的资源获取字符串

i.putExtra(Intent.EXTRA_TEXT, getResources().getString(R.string.default_message_wa));

这是我的方法：

首先，您检查该人是否甚至拥有WhatsApp帐户：

@RequiresPermission(permission.READ_CONTACTS)
public String getContactMimeTypeDataId(@NonNull Context context, String contactId, @NonNull String mimeType) {
    if (TextUtils.isEmpty(mimeType) || !PermissionUtil.hasPermissions(context, Manifest.permission.READ_CONTACTS))
        return null;
    ContentResolver cr = context.getContentResolver();
    Cursor cursor = cr.query(ContactsContract.Data.CONTENT_URI, new String[]{Data._ID}, Data.MIMETYPE + "= ? AND "
            + ContactsContract.Data.CONTACT_ID + "= ?", new String[]{mimeType, contactId}, null);
    if (cursor == null)
        return null;
    if (!cursor.moveToFirst()) {
        cursor.close();
        return null;
    }
    String result = cursor.getString(cursor.getColumnIndex(Data._ID));
    cursor.close();
    return result;
}

如果一切看起来不错，则可以像从网络上打开它一样 

            final String contactMimeTypeDataId = getContactMimeTypeDataId(context, contactId, "vnd.android.cursor.item/vnd.com.whatsapp.profile");
            if (contactMimeTypeDataId != null) {
                final String whatsAppPhoneNumber = PhoneNumberHelper.normalizePhone(phoneNumber);
                String url = "https://api.whatsapp.com/send?phone="+ whatsAppPhoneNumber ;
                intent = new Intent(Intent.ACTION_VIEW,Uri.parse(url));
                intent.addFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET | Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP)
                .setPackage("com.whatsapp");
                startActivity(intent);
            }

您还可以在所有这些之前检查是否已安装WhatsApp：

        final PackageManager packageManager = context.getPackageManager();
        final ApplicationInfo applicationInfo = packageManager.getApplicationInfo("com.whatsapp", 0);
        if (applicationInfo == null)
           return;

答案 12 :(得分：-2)

尝试使用Intent.EXTRA_TEXT代替sms_body作为额外密钥。根据WhatsApp的文档，这是你必须使用的。

来自their website的示例：

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
startActivity(sendIntent);

他们的示例使用Intent.ACTION_SEND代替Intent.ACTION_SENDTO，所以我不确定WhatsApp是否支持通过意图系统直接发送给联系人。一些快速测试应该让你确定。
