我正在使用下面的代码，我的textview链接是可点击的，但我想制作whatsapp和facebook的特定按钮共享..我在stackoverflow中引用了几篇文章，但我想要textview。对于我之前做过的webview，很容易。请帮助/建议textview共享。我不希望所有按钮都打开。我希望每个listview后有一个facebook和whatsapp图标。点击whatsapp应该打开文本以进行共享

intent.setPackage("com.whatsapp");
if (intent != null) {
intent.putExtra(Intent.EXTRA_TEXT, msg);
startActivity(Intent.createChooser(intent, ""));
