Android：我的 if else 语句出现编译错误

Question

Eclispe 编译器向我显示 else if 上的 else 语句的错误语法。谁能告诉我出了什么问题吗？谢谢！

代码

//click on one of chapters
    list.setOnItemClickListener(new OnItemClickListener() 
    {
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
        {

            String item = ((TextView)view).getText().toString();

            Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show();

            //Choose Chapter 1
            if (item.equalsIgnoreCase("I. The Global Business Environment")); {
            //go to chapter 1
            startActivity(new Intent(ChaptersActivity.this, Chapter1Activity.class));
            } else if (item.equalsIgnoreCase("II. Information Systems")); {
                //go to chapter 2
                startActivity(new Intent(ChaptersActivity.this, Chapter2Activity.class));
            }

          //Choose Chapter 3
            else if (item.equalsIgnoreCase("III. Operations Management"));
            {
                //go to chapter 3
                startActivity(new Intent(ChaptersActivity.this, Chapter3Activity.class));
            }

          //Choose Chapter 4
            else if (item.equalsIgnoreCase("IV. Marketing"));
            {
                //go to chapter 4
                startActivity(new Intent(ChaptersActivity.this, Chapter4Activity.class));
            }

          //Choose Chapter 5
            else if (item.equalsIgnoreCase("V. Managing Human Capital"));
            {
                //go to chapter 5
                startActivity(new Intent(ChaptersActivity.this, Chapter5Activity.class));
            }

          //Choose Chapter 6
            else if (item.equalsIgnoreCase("VI. Preparing for the Examination"));
            {
                //go to chapter 6
                startActivity(new Intent(ChaptersActivity.this, Chapter6Activity.class));
            }
        }
    });

他们在“其他”代码单词上显示错误语法，有什么想法吗？

Answer 1

if 条件末尾有一个分号：

if (item.equalsIgnoreCase("I. The Global Business Environment")); {

结束 if 语句，{ 开始一个新块，然后 else 突然出现。

Answer 2

; 出现在每个 if-else 条件语句中。您最好将它们删除并尝试再次构建它:)
