我尝试了以下发送带有附件的电子邮件的代码。它在尝试发送时确实显示附件，但问题是它只发送带有主题和正文但没有附件的电子邮件。我会感谢你的帮助
emailButton = (Button) findViewById(R.id.emailButton);
textTo = (EditText) findViewById(R.id.txtenterserial);
textSubject = (EditText) findViewById(R.id.txtenterseri);
textMessage = (EditText) findViewById(R.id.txtenters);
emailButton.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 i = new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
File data = null;
try {
Date dateVal = new Date();
String filename = dateVal.toString();
data = File.createTempFile("Report", ".csv");
Log.d("vvvvvv", data.toString());
FileWriter out = (FileWriter) GenerateCsv.generateCsvFile(data, "Name,Data1");
//Log.d("SSSSHOOOOW", out.toString());
i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(data));
i.putExtra(Intent.EXTRA_EMAIL, new String[] { to });
i.putExtra(Intent.EXTRA_SUBJECT, subject);
i.putExtra(Intent.EXTRA_TEXT, message);
startActivity(Intent.createChooser(i, "E-mail"));
} catch (IOException e) {
e.printStackTrace();
}
}
});
public static class GenerateCsv {
public static FileWriter generateCsvFile(File sFileName,String fileContent) {
FileWriter writer = null;
try {
writer = new FileWriter(sFileName);
writer.append(fileContent);
writer.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
writer.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return writer;
}
}
这是 LogCat
