java将信息发送到电子邮件

Question

我有一个活动，它有两个文本字段，用户可以在其中输入一些文本

在它们下面有一个按钮，我想在两个文本字段中提交信息输入。无论是电子邮件还是信息

是否有一种方法可以让活动基本上向我提交用户信息

Answer 1

你需要使用意图打开“撰写新邮件”，并填写所需数据

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_EMAIL  , new String[]{emailAddressEditText.getText().toString()});
intent.putExtra(Intent.EXTRA_SUBJECT, emailSubjectEditText.getText().toString());
intent.putExtra(Intent.EXTRA_TEXT   , emailBodyEditText.getText().toString());
try {
    startActivity(Intent.createChooser(intent, "Leave feedback..."));
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(MyActivity.this, "No email clients installed.", Toast.LENGTH_SHORT).show();
}

Answer 2

一,。使用意图

二,。使用setType（“消息/rfc822”）

buttonSend = (Button) findViewById(R.id.buttonSend);
textTo = (EditText) findViewById(R.id.editTextTo);
 textSubject = (EditText) findViewById(R.id.editTextSubject);
 textMessage = (EditText) findViewById(R.id.editTextMessage);

 buttonSend.setOnClickListener(new OnClickListener() {

 @Override
 public void onClick(View v) {

 String to = textTo.getText().toString();
 String subject = textSubject.getText().toString();
 String message = textMessage.getText().toString();

     Intent email = new Intent(Intent.ACTION_SEND);
     email.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});
     email.putExtra(Intent.EXTRA_SUBJECT, subject);
     email.putExtra(Intent.EXTRA_TEXT, message);

     email.setType("message/rfc822");

 startActivity(Intent.createChooser(email, "Choose an Email client :"));
}
});
