如何在 Android 应用程序中单击按钮时发送 TextView 数据？

Question

首先，我对 Android 和 NFC 都很陌生，尽管我对 Java 很熟悉。我正在制作一个 NFC android 应用程序作为我的主要项目，我想邮寄某个列表（显示结果）单击按钮。

谁能帮我写代码或指导我看一些分步教程...

谢谢期待..!!!

Answer 1

使用Intent 启动能够发送邮件并传递您的数据的应用程序：

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
            "mailto","abc@gmail.com", null));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "EXTRA_SUBJECT");
startActivity(Intent.createChooser(emailIntent, "Send email..."));

Answer 2

In above code just add this line:
emailIntent.putExtra(Intent.EXTRA_TEXT, "Content of the email");

Answer 3

if you want to get body of email from another activity then pass edittext text in intent from activity where your edittext is and receive it to another activity where your intent is

for example
Activity A

EditText bodyText=(EditText)findViewById(R.id.body_text);
EditText subjectText=(EditText)findViewById(R.id.subject_text);

String emailBody=bodyText.getText().toString().trim();
String emailSubject=subjectText.getText().toString().trim();

Intent inte=new Intent(A.this,B.class);
inte.putExtra("body",bodyText);
inte.purExtra("subject",emailSubject);
startActivity(inte);

and in Activity B receive the intent like this,

Intent intent=getIntent();
String bodyText=intent.getExtras().getString("body");
String subjectText=intent.getExtras().getString("subject");

Intent emailInte=new Intent(Intent.ACTION_SENDTO,Uri.fromParts("mailto","xyz@gmail.com",null));
emailInte.putExtra(Intent.EXTRA_SUBJECT,subjectText);
emailInte.putExtra(Intent.EXTRA_TEXT, bodyText);
startActivity(Intent.createChooser(emailInte,"Send email using"));
