Android 按钮 onclick 提交到电子邮件

Question

我使用 Java 和 Xml 已有几个月了，感谢 StackOverflow 上大家的帮助，我学到了很多东西。

我的问题是关于与提交按钮相关的android java 编程。

目前我正在尝试弄清楚如何向电子邮件地址提交值（在幕后）

假设我们有一个文本字段和一个按钮；我想获取在文本字段中输入的值，并将其提交到 onclick 的电子邮件地址。

我无法在网上找到任何可以告诉我如何执行此操作的内容。

预先感谢您阅读我的帖子，并期待您的建议。

这是一个很好的例子，说明如何使用 Intents 非常方便！
Android 有一堆预定义的 Intent，可以在系统内执行某些操作；您之前可能点击过某张图片，然后会弹出一个对话框，询问您是否要在图库中或在 Astro 等第三方应用程序中查看它。图像的观看有其自身预先确定的意图。

发送电子邮件也有其自己预先确定的意图：android.content.Intent.ACTION_SEND。您需要使用该属性创建一个意图，然后附加额外信息（即要发送到的地址、主题/消息正文等）。

示例代码：

// Data members
private Intent emailIntent;
private String feedback;
private EditText feedbackBox;

// Create the Intent, and give it the pre-defined value
// that the Android machine automatically associates with
// sending an email.
emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("plain/text");

// Put extra information into the Intent, including the email address
// that you wish to send to, and any subject (optional, of course).
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"[email protected]"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Insert subject here");

// Acquire feedback from an EditText and save it to a String.
feedback = feedbackBox.getText().toString();

// Put the message into the Intent as more extra information,                   
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, feedback);

// Start the Intent, which will launch the user's email 
// app (make sure you save any necessary information in YOUR app
// in your onPause() method, as launching the email Intent will
// pause your app). This will create what I discussed above - a
// popup box that the user can use to determine which app they would like
// to use in order to send the email.
startActivity(Intent.createChooser(emailIntent, "Insert title for dialog box."));

我希望这有帮助！

Answer 3

试试这个

Intent intent = new Intent(Intent.ACTION_SENDTO);
    intent.setData(Uri.parse("mailto:Type email address here"));
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }

效果很好

 String   mail=mailid.getText().toString();
 String   msubject=subject.getText().toString();
 String   mbody=body.getText().toString();
    Log.i("Send email", "");
    String[] TO = {mail};
    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_SUBJECT, "Static subject "+ msubject);
    emailIntent.putExtra(Intent.EXTRA_TEXT, "Static body "+ mbody);

    try {
        startActivity(Intent.createChooser(emailIntent, "Send mail..."));
        finish();

    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(MainActivity.this, "There is no email client installed.", Toast.LENGTH_SHORT).show();
    }
