發送電子郵件的問題…返回上一個活動

Question

我有兩個活動-A和B。我有一個活動A的列表，如果單擊它，它將轉到活動B。在活動B上，我有一個用於共享電子郵件的按鈕，其代碼如下：

shareEmail = (Button) findViewById(R.id.emailButton);

    shareEmail.setOnClickListener(new View.OnClickListener() 
    {
        public void onClick(View v)
        {
            System.out.println("!!! email !!!");


         Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
             emailIntent.setType("text/html");


         emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "sharing something interesting" );
         emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "sharing something interesting !!" );

         //hideKeyboard();

         activityB.this.startActivity(emailIntent);


        }
    });

現在，當我發送電子郵件時，電子郵件窗口關閉，活動B也關閉。 我不確定為什么會這樣。 有什么提示嗎？ 謝謝。

您必須在開始活動中使用intent.crateChoose。 現在使用編輯后的代碼。

shareEmail = (Button) findViewById(R.id.emailButton);

    shareEmail.setOnClickListener(new View.OnClickListener() 
    {
        public void onClick(View v)
        {
            System.out.println("!!! email !!!");


         Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
             emailIntent.setType("text/html");


         emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "sharing something interesting" );
         emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "sharing something interesting !!" );

         //hideKeyboard();

         activityB.this.startActivity(Intent.createChooser(emailIntent,"Sending Mail..."));


        }
    });
