java - 找不到这个支架去哪里？

Question

我不明白为什么 Eclipse 提示我的“OnClick”方法的第二个括号...

我知道这是一件简单的事情，但我似乎无法解决它!

我的 Activity 代码:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    CallService cs = new CallService();
    TotalTime = TotalTime + (cs.EndTime - cs.StartTime);
    Button button = (Button) findViewById(R.id.button1);

    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Toast toast = Toast.makeText(getApplicationContext(), ""+TotalTime, Toast.LENGTH_SHORT);
            toast.show();
        } // <-- Why is it complaining about this bracket?!
}

对于每个左括号或括号，您都需要将其关闭，您还需要用分号结束每个语句。编译器希望添加 });:

   // You open these, so you need to close them in order
   //                       v                           v
   button.setOnClickListener(new View.OnClickListener() {
       //                          v
       public void onClick(View v) {
           // Perform action on click

           Toast toast = Toast.makeText(getApplicationContext(), ""+TotalTime, Toast.LENGTH_SHORT);
           toast.show();
       }
   //  ^    
   }); // This is what the compiler wants
