通过 WhatsApp 发送消息 [英] Sending message through WhatsApp

问题描述

因为我发现了一些较旧的帖子，表明 whatsapp 不支持这一点，我想知道是否发生了一些变化，以及是否有办法打开一个带有我通过一个号码发送的号码的 whatsapp '聊天'意图?

解决方案

WhatsApp 的点击聊天"功能允许您开始聊天某人没有将他们的电话号码保存在您的手机中地址簿.只要你知道这个人的电话号码，你就可以创建一个链接，让您可以开始与他们聊天.

示例:https://wa.me/15551234567?text=Im%20interested%20in%20your%20car%20for%20sale

原答案这是解决方案

public void onClickWhatsApp(View view) {包管理器 pm=getPackageManager();尝试 {Intent waIntent = new Intent(Intent.ACTION_SEND);waIntent.setType("text/plain");String text = "你的文本在这里";PackageInfo info=pm.getPackageInfo(com.whatsapp", PackageManager.GET_META_DATA);//检查包是否存在.如果没有，那么代码//在catch块中将被调用waIntent.setPackage(com.whatsapp");waIntent.putExtra(Intent.EXTRA_TEXT, 文本);startActivity(Intent.createChooser(waIntent, Share with"));} catch (NameNotFoundException e) {Toast.makeText(this, WhatsApp not Installed", Toast.LENGTH_SHORT).展示();}}

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?

WhatsApp's Click to Chat feature allows you to begin a chat with someone without having their phone number saved in your phone's address book. As long as you know this person’s phone number, you can create a link that will allow you to start a chat with them.

Original answer Here is the solution

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();
   }  

}
