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[]{"[email protected]","[email protected]"};

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
