向WhatsApp联系人发送消息

Question

I recently tried the code to send message to whatsapp using intent. But i was wondering if there's any way to directly send the message with the intent action rather than having the text typed in the message box of that contact once a contact is selected. I want the text to be sent to the contact once i select it.

Answer 1

Whats app provide 2 methods to send messages:

1. Custom URL Scheme
2. Android intent system

Custom URL Scheme

Opening whatsapp://send?text= followed by the text to send, will open WhatsApp, allow the user to choose a contact, and pre-fill the input field with the specified text.

Eg:

 <a href="whatsapp://send?text=Hello%20World!">Hello, world!</a> 

Android intent system

Like most social apps on Android, WhatsApp listens to intents to share media and text. Simply create an intent to share text, for example, and WhatsApp will be displayed by the system picker:

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);
