通过WhatsApp的发送邮件 [英] Sending message through WhatsApp

问题描述

因为我发现了一些旧帖子，告诉了WhatsApp的不支持此，我想知道如果事情发生了变化，如果有一种方式打开了WhatsApp聊天有一个数字，我通过发送意图是什么？

Since I found some older posts, that tell that whatsapp doesn't support this, I was wondering if something had changed and if there is a way to open a whatsapp 'chat' with a number that I'm sending through an intent?

推荐答案

下面是解决方案

public void onClickWhatsApp(View view) {

    PackageManager pm=getPackageManager();
    try {

        Intent waIntent = new Intent(Intent.ACTION_SEND);
        waIntent.setType("text/plain");
        String text = "YOUR TEXT HERE";

        PackageInfo info=pm.getPackageInfo("com.whatsapp", PackageManager.GET_META_DATA);
        //Check if package exists or not. If not then code 
        //in catch block will be called
        waIntent.setPackage("com.whatsapp");

        waIntent.putExtra(Intent.EXTRA_TEXT, text);
        startActivity(Intent.createChooser(waIntent, "Share with"));

   } catch (NameNotFoundException e) {
        Toast.makeText(this, "WhatsApp not Installed", Toast.LENGTH_SHORT)
                .show();
   }  

}
