Android 如何通过电子邮件共享以广告标题为主题、以广告描述为主体的广告

我是android新手。经过大量的搜索，我把这个问题贴在这里。我的应用程序包含在listview中显示的广告，我正在尝试通过电子邮件共享广告。我已经包含了电子邮件的代码，但它没有从SingleMenuItem.java活动中提取标题，将其显示在电子邮件的主题中，并将其描述显示在正文中。有人能帮我吗？下面是代码

Email.java

  public class Email extends Activity {
  Button  send;
  EditText address, subject, emailtext;
   @Override
  public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.email);
  send=(Button ) findViewById(R.id.send);
  address=(EditText) findViewById(R.id.emailaddress);
  subject=(EditText) findViewById(R.id.emailsubject);
  emailtext=(EditText) findViewById(R.id.emailtext);

  send.setOnClickListener(new OnClickListener() {

                public void onClick(View  v) {
                        // TODO Auto-generated method stub

               final Intent emailIntent = new         Intent(android.content.Intent.ACTION_SEND);

                               emailIntent.setType("plain/text");

         emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String []{ address.getText().toString()});

                                  emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject.getText());

                emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailtext.getText());

                            Email.this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));

                }


        });
      }
     }

SingleMenuItemActivity.java

    public class SingleMenuItemActivity  extends Activity {

         // JSON node keys
             private static final String TAG_TITLE = "title";
             private static final String TAG_DATE = "date";
             private static final String TAG_NAME = "name";
             private static final String TAG_CONTENT = "content";
         @Override
            public void onCreate(Bundle savedInstanceState) {
               super.onCreate(savedInstanceState);
            setContentView(R.layout.single_list_item);


      // getting intent data
      Intent in = getIntent();

       // Get JSON values from previous intent
      String title = in.getStringExtra(TAG_TITLE);
      String date = in.getStringExtra(TAG_DATE);
      String name = in.getStringExtra(TAG_NAME);
      String content = in.getStringExtra(TAG_CONTENT);

     // Displaying all values on the screen
        TextView lblName = (TextView) findViewById(R.id.name_label);
        TextView lblCost = (TextView) findViewById(R.id.email_label);
        TextView lblDesc = (TextView) findViewById(R.id.mobile_label);
        TextView lblCont = (TextView) findViewById(R.id.content_label);

       lblName.setText(title);
       lblCost.setText(date);
       lblDesc.setText(name);
       lblCont.setText(content);

      final ImageView email3 = (ImageView) findViewById(R.id.email);


       email3.setOnClickListener(new View.OnClickListener() {
         public void onClick(View v){
              //my codes
             startActivity(new Intent(SingleMenuItemActivity.this, Email.class));   
          }
        });
             }
            }

private void sendMail（字符串appName，字符串adLink）{
String msg=“你好，
最近，我下载了”+appName+“”+
“从游戏商店。我发现这是一个非常具有挑战性和伟大的游戏。”+
“
我想向您推荐这个游戏。



”+
“
谢谢”；
String sub=“立即获取，它在Play Store中”；
意向电子邮件=新意向（意向.行动\发送）；
email.setType（“text/html”）；
email.putExtra（Intent.EXTRA_SUBJECT，sub）；
email.putExtra（android.content.Intent.EXTRA_TEXT，Html.fromHtml（msg））；
email.setType（“message/rfc822”）；
startActivity（Intent.createChooser（电子邮件，“选择电子邮件客户端：”）；
}

在您的情况下，无需创建

电子邮件。class

只需在单击

email3

按钮的侦听器中编写您的电子邮件意图代码即可

代码应该如下所示

email3.setOnClickListener(new View.OnClickListener() {
           public void onClick(View v){
                //my codes
             Intent emailIntent = Intent(android.content.Intent.ACTION_SENDTO);
        emailIntent.setType("text/html");
        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, title);
        emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, content));
        startActivity(Intent.createChooser(emailIntent, "Email to Friend"));
           }
        });

消息正文应取自广告内容。bcoz广告不是固定的

email3.setOnClickListener(new View.OnClickListener() {
           public void onClick(View v){
                //my codes
             Intent emailIntent = Intent(android.content.Intent.ACTION_SENDTO);
        emailIntent.setType("text/html");
        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, title);
        emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, content));
        startActivity(Intent.createChooser(emailIntent, "Email to Friend"));
           }
        });
