android-拨打whatsapp电话

Question

我想向特定用户拨打 WhatsApp 电话。我试过这个但它不起作用：

Uri uri = Uri.parse("callto:" + phoneNUmber);
Intent i = new Intent(Intent.ACTION_CALL, uri);
i.setPackage("com.whatsapp");
startActivity(i);

我知道如何创建 WhatsApp 消息，代码类似并且有效：

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

Answer 1

简单的解决方案是，查询 ContactContract.Data _id 和 MIME 类型。

ContentResolver resolver = context.getContentResolver();  
cursor = resolver.query(
            ContactsContract.Data.CONTENT_URI,
            null, null, null,
            ContactsContract.Contacts.DISPLAY_NAME);

//Now read data from cursor like 

while (cursor.moveToNext()) {
      long _id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID));
      String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
      String mimeType = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));

      Log.d("Data", _id+ " "+ displayName + " " + mimeType );

}

输出将如下所示

12561 Snow vnd.android.cursor.item/vnd.com.whatsapp.profile

12562 Snow vnd.android.cursor.item/vnd.com.whatsapp.voip.call

现在只在数据库或其他地方保存那些 MIME 类型为 vnd.android.cursor.item/vnd.com.whatsapp.voip.call

的 _Id

然后你像这样与这些联系人发起 Whatsapp 通话

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);

// the _ids you save goes here at the end of /data/12562     
intent.setDataAndType(Uri.parse("content://com.android.contacts/data/_id"),
    "vnd.android.cursor.item/vnd.com.whatsapp.voip.call");
intent.setPackage("com.whatsapp");
 
startActivity(intent);

Answer 2

要进行 WhatsApp 视频通话，请使用以下 mime 字符串：

String mimeString = "vnd.android.cursor.item/vnd.com.whatsapp.video.call";

要使用以下 mime 字符串进行 WhatsApp 语音通话：

 String mimeString = "vnd.android.cursor.item/vnd.com.whatsapp.voip.call";

使用下面的代码：

 String displayName = null;
 String name="ABC" // here you can give static name.
 Long _id;
 ContentResolver resolver = getApplicationContext().getContentResolver();
 cursor = resolver.query(ContactsContract.Data.CONTENT_URI, null, null, null, ContactsContract.Contacts.DISPLAY_NAME);
 while (cursor.moveToNext()) {
    _id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID));
    displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
    String mimeType = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));
    if (displayName.equals(name)) {
        if (mimeType.equals(mimeString)) {
            String data = "content://com.android.contacts/data/" + _id;
            Intent sendIntent = new Intent();
            sendIntent.setAction(Intent.ACTION_VIEW);
            sendIntent.setDataAndType(Uri.parse(data), mimeString);
            sendIntent.setPackage("com.whatsapp");
            startActivity(sendIntent);
        }
    }
}

如果我们传递 rawContactId，那么我们可以使用它来直接获取与 whatsapp 调用 URI 关联的 ID。

private void whatsAppCall(Context context, String rawContactId) {
        try {

            int id = whatsAppCallId(context, rawContactId);

            Intent intent = new Intent();
            intent.setAction(Intent.ACTION_VIEW);
            String uriString = "content://com.android.contacts/data/" + id;
            intent.setDataAndType(Uri.parse(uriString), "vnd.android.cursor.item/vnd.com.whatsapp.voip.call");
            intent.setPackage("com.whatsapp");
            startActivity(intent);
        } catch (Exception e) {
            Log.e(TAG, "whatsAppCall Exception: " + e);
        }
    }



 private long whatsAppCallId(Context context, String rawContactId){ 
    ContentResolver resolver = context.getContentResolver();

            String selection = ContactsContract.Data.MIMETYPE + " = ? AND " + ContactsContract.Data.RAW_CONTACT_ID + " = ? ";
            String[] selectionArgs = new String[] { "vnd.android.cursor.item/vnd.com.whatsapp.voip.call", rawContactId };


            Cursor cursor = resolver.query(
                    ContactsContract.Data.CONTENT_URI,
                    null, selection, selectionArgs,
                    ContactsContract.Contacts.DISPLAY_NAME);
            long _id=0;

            while (cursor.moveToNext()) {
                _id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID));
                String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
                String mimeType = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));
                Log.d(TAG, "Data: " + _id+ " "+ displayName + " " + mimeType );
            }
return _id;

}

此代码用于检查号码是否有whatsapp并进行whatsapp音视频通话

首先检查号码是否有whatsapp ...如果你不知道

 if  rowContactId (return type of hasWhatsapp) is  not equal to '0'   then this number has whatsapp.

.

public String hasWhatsapp(  getContactIDFromNumber(795486179).toString(),MAinactivity.this ) 
{
        String rowContactId = null;
        boolean hasWhatsApp;

        String[] projection = new String[]{ContactsContract.RawContacts._ID};
        String selection = ContactsContract.Data.CONTACT_ID + " = ? AND account_type IN (?)";
        String[] selectionArgs = new String[]{contactID, "com.whatsapp"};
        Cursor cursor = getContentResolver().query(ContactsContract.RawContacts.CONTENT_URI, projection, selection, selectionArgs, null);
        if (cursor != null) {
            hasWhatsApp = cursor.moveToNext();
            if (hasWhatsApp) {
                rowContactId = cursor.getString(0);
            }
            cursor.close();
        }
        return rowContactId;
    }


public static int getContactIDFromNumber( contactNumber,Context context)

        int phoneContactID = new Random().nextInt();
        Cursor contactLookupCursor = context.getContentResolver().query(Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,contactNumber),new String[] {ContactsContract.PhoneLookup.DISPLAY_NAME, ContactsContract.PhoneLookup._ID}, null, null, null);
        while(contactLookupCursor.moveToNext())
        {
            phoneContactID = contactLookupCursor.getInt(contactLookupCursor.getColumnIndexOrThrow(ContactsContract.PhoneLookup._ID));
        }
        contactLookupCursor.close();        

        return phoneContactID;

Answer 6

@Adnan Khan 提供的答案适用于 Android 11，但我想提供他的答案的 Kotlin 版本：

val resolver: ContentResolver = requireContext().contentResolver
val cursor: Cursor? = resolver.query(
    ContactsContract.Data.CONTENT_URI,
        null, null, null,
    ContactsContract.Contacts.DISPLAY_NAME)

while(cursor!!.moveToNext()) {
    val _id: Long = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID))
    val displayName: String = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME))
    val mimeType: String = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE))

    Log.i("Intents", "$_id $displayName $mimeType")

现在，Kotlin 的意图是这样的： _id 是你从之前路由得到的值

val intent = Intent()
intent.action = Intent.ACTION_VIEW
intent.setDataAndType(Uri.parse("content://com.android.contacts/data/_id"),
    "vnd.android.cursor.item/vnd.com.whatsapp.voip.call")
intent.setPackage("com.whatsapp")
startActivity(intent)

最后但同样重要的是，将以下内容添加到 AndroidManifest.xml：

<uses-permission
    android:name="android.permission.CALL_PHONE"
    androd:maxSdkVersion="30" />
<uses-permission
    android:name="android.permission.READ_CONTACTS"
    androd:maxSdkVersion="30" />

在此之后，您需要转到设置 -> 应用 -> Select 您的应用并将这两个权限标记为允许。

应该有一种方式让应用程序在第一次询问您时是运行，但那是另一个话题。
