Answer 3

你可以试试这个：

选择发送电子邮件

：

  protected void sendEmail() {
      Log.i("Send email", "");
      String[] TO = {""};
      String[] CC = {""};
      Intent emailIntent = new Intent(Intent.ACTION_SEND);

      emailIntent.setData(Uri.parse("mailto:"));
      emailIntent.setType("text/plain");
      emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
      emailIntent.putExtra(Intent.EXTRA_CC, CC);
      emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Your subject");
      emailIntent.putExtra(Intent.EXTRA_TEXT, "Email message goes here");

      try {
         startActivity(Intent.createChooser(emailIntent, "Send mail..."));
         finish();
         Log.i("Finished sending email...", "");
      }
      catch (android.content.ActivityNotFoundException ex) {
         Toast.makeText(MainActivity.this, "There is no email client installed.", Toast.LENGTH_SHORT).show();
      }
   }
