JAVA int 强制类型转换错误提示（Cannot cast from Object to int）

在将ANDROID源码导入eclipse时，出错提示如下：
    public void addActiveCid(int cid) {
        if (cidActiveList == null) {
            cidActiveList = new ArrayList();
        }
        for (int i=0;i
            if(cid == cidActiveList.get(i)) {                 // 行 657
                return;
            }
        }
        cidActiveList.add(cid);
        Log.d(LOG_TAG, "[" + phone.getPhoneId() + "]addActiveCid("+cid+") cidActive("+cidActive+") List("+cidActiveList+")");
    }
    public void removeActiveCid(int cid) {
        if (cidActiveList != null) {
            for (int i=0;i
                if(cid == cidActiveList.get(i)) {          // 行667.
                    cidActiveList.remove(i);
                }
            }
        }

Incompatible operand types int and Object    DataConnectionTracker.java   /check/frameworks/base/telephony/java/com/android/internal/telephony    line 667    Java Problem

将 if(cid == cidActiveList.get(i))加入强制转换int后，即

           if(cid == (int)cidActiveList.get(i))
又出现如下错误提示：
Cannot cast from Object to int    DataConnectionTracker.java   /check/frameworks/base/telephony/java/com/android/internal/telephony    line 657    Java Problem

最后在网上找了一翻，最终改为如下， 即问题解决。
        if(cid == (Integer)cidActiveList.get(i))

特此记录，以备后忘。

(int) (v.getTag())  ==》
