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

2013-06-19 16:20:20

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);

}

}

}

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

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。
