Question

Eclispe编译器向我显示我的else语句中的错误sntax。谁能告诉我什么是错的？谢谢！

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”代码字上显示错误sntax，有什么想法吗？

Answer 1

你的if条件结尾处有一个semicolon：

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

结束if语句，{开始一个新的块，然后出现在其他地方。

Answer 2

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