android-make whatsapp调用

Question

我想向特定用户发出WhatsApp呼叫.我尝试过这个并不起作用:

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,它的工作原理:

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,对于_id和MIME类型,查询ContactContract.Data.

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DB或其他地方保存那些MIME类型为的_Ids vnd.android.cursor.item/vnd.com.whatsapp.voip.call

然后你就像这样对这些联系人发起Whatsapp呼叫

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

要使用WhatsApp视频通话,请使用以下mime-string:

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

要在mime-string下面使用WhatsApp语音呼叫:

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

使用以下代码:

 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);
        }
    }
}

此代码用于检查号码是否有whatsapp并进行whatsapp音频和视频通话

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)
    {
        contactNumber = Uri.encode(contactNumber);
        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;
    }
