android中调用系统的发送短信、发送邮件、打电话功能

1 调用发送短信功能：

Uri smsToUri = Uri.parse("smsto:");
Intent sendIntent = new Intent(Intent.ACTION_VIEW, smsToUri);
sendIntent.putExtra("address", "123456"); //电话号码，这行去掉的话，默认就没有电话
sendIntent.putExtra("sms_body","短信内容");
sendIntent.setType("vnd.android-dir/mms-sms");
startActivity(sendIntent);

2 调用发送邮件功能：

Intent email = new Intent(android.content.Intent.ACTION_SEND);
email.setType("plain/text");
String[] emailReciver = new String[]{"xxxx@qq.com","yyy@xx.com"};

String emailSubject = "从问道分享来的文章";
StringemailBody = internetpath;
//设置邮件默认地址
email.putExtra(android.content.Intent.EXTRA_EMAIL, emailReciver);
//设置邮件默认标题
email.putExtra(android.content.Intent.EXTRA_SUBJECT, emailSubject);
//设置要默认发送的内容
email.putExtra(android.content.Intent.EXTRA_TEXT, emailBody);
//调用系统的邮件系统
startActivity(Intent.createChooser(email, "请选择邮件发送软件"));

3.打电话
Intent intent = new Intent();
intent.setAction("android.intent.action.DIAL");
intent.setData(Uri.parse("tel:400 616 0066"));
startActivity(intent);
