Question

我在html文件和java代码中有一个用于通过电子邮件共享图像的按钮，现在我需要将java中按钮代码的“onclick”放到html的“onClick”中，通过phonegap中的电子邮件实现“数据共享”。因为我是html和phonegap的新手，我不知道这个程序，请帮助我。

这是我的java代码

public class MainActivity extends Activity {

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);

        Button addImage = (Button) findViewById(R.id.send);
        addImage.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {


                GMailSender mailsender = new GMailSender("xya@gmail.com", "pw123");

                String[] toArr = { "abc@gmail.com", "efg@gmail.com" };
                mailsender.set_to(toArr);
                mailsender.set_from("sender@gmail.com");
                mailsender.set_subject("This is an email sent using my Mail JavaMail wrapper from an Android device.");
                mailsender.setBody("Email body.");

                try {
                    //mailsender.addAttachment("/sdcard/filelocation");

                    if (mailsender.send()) {
                        Toast.makeText(MainActivity.this,
                                "Email was sent successfully.",
                                Toast.LENGTH_LONG).show();
                    } else {
                        Toast.makeText(MainActivity.this, "Email was not sent.",
                                Toast.LENGTH_LONG).show();
                    }
                } catch (Exception e) {

                    Log.e("MailApp", "Could not send email", e);
                }
            }
        });

    }

html代码

<body >     
  <button onclick="  " id="email">Send_Email </button>
</body>

我认为你可以通过点击按钮调用javascript函数来实现这一点。 javascript函数可以使用ajax或JQuery上传文件。我在这个链接中找到了它 PhoneGap File Upload Using jQuery Ajax

如何在html按钮的“onClick”上调用java函数？
