我正在尝试使用此代码，这是从此处获取的示例https://gist.github.com/2383248，但它在 public void onClick 上出现错误，即

此行的多个标记 - 实现 android.view.View.OnClickListener.onClick - 语法错误，插入“}”以完成 MethodBody，但是当我添加大括号时，它只是在多次尝试和不同建议和想法失败后引发另一个错误。

这可能是我的语法错误和糟糕的编码（刚开始学习编程），但有没有人知道如何解决这个问题或指出我正确的方向，我将不胜感激。

 public class ICSCalendarActivity extends Activity implements View.OnClickListener{

Button button1;

int year1;  
int month1;  
int day1;
int ShiftPattern;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);



    button1 = (Button)findViewById(R.id.openButton);     
    button1.setText("open");   
    button1.setOnClickListener(this);

    Bundle extras = getIntent().getExtras(); 

    year1 = extras.getInt("year1"); 
    day1 = extras.getInt("day1"); 
    month1 = extras.getInt("month1");

    ShiftPattern = extras.getInt("ShiftPattern");
}

public void onClick(View v){

private static void addToCalendar(Context ICSCalendarActivity, final String title, final long dtstart, final long dtend) {
    final ContentResolver cr = ICSCalendarActivity.getContentResolver();
    Cursor cursor ;

函数内部不能有static方法定义。addToCalendaronClick

public class ICSCalendarActivity extends Activity implements View.OnClickListener{

Button button1;

int year1;  
int month1;

    button1.setOnClickListener(this);

    Bundle extras = getIntent().getExtras(); 

    year1 = extras.getInt("year1");

    month1 = extras.getInt("month1");

    ShiftPattern = extras.getInt("ShiftPattern");
}

public void onClick(View v){

您不能在另一个方法中定义一个方法。在您的代码中，您在 onClick() 方法中定义了 addToCalendar( ) 方法。而是在外部定义方法并从 onClick() 方法调用它。

public void onClick(View v)
{
     addTocalender(context, string, longVal1,  longVal2);
}

private static void addToCalendar(Context ICSCalendarActivity,
        final String title, final long dtstart, final long dtend)
{
 ....
 ....
}
