推荐答案

方法1-使用android组件名称

 public static void openWhatsAppConversation(Context context, String number, String message) {

    number = number.replace(" ", "").replace("+", "");

    Intent sendIntent = new Intent("android.intent.action.MAIN");

    sendIntent.setType("text/plain");
    sendIntent.putExtra(Intent.EXTRA_TEXT, message);
    sendIntent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.Conversation"));
    sendIntent.putExtra("jid", PhoneNumberUtils.stripSeparators(number) + "@s.whatsapp.net");

    context.startActivity(sendIntent);
}

方法2-使用whatsapp api uri

public static void openWhatsAppConversationUsingUri(Context context, String numberWithCountryCode, String message) {

    Uri uri = Uri.parse("https://api.whatsapp.com/send?phone=" + numberWithCountryCode + "&text=" + message);

    Intent sendIntent = new Intent(Intent.ACTION_VIEW, uri);

    context.startActivity(sendIntent);
}
