在android 获取手机信息的时候用到这样一段代码：

public class BasicInfo {

      public StringgetPhoneNumber()

      {

            //获取手机号 MSISDN，很可能为空

            TelephonyManager tm =(TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

            StringBufferinf = new StringBuffer();

            switch(tm.getSimState()){//getSimState()取得sim的状态  有下面6中状态 

                    caseTelephonyManager.SIM_STATE_ABSENT :inf.append("无卡");returninf.toString();  

                   caseTelephonyManager.SIM_STATE_UNKNOWN :inf.append("未知状态");returninf.toString(); 

                  caseTelephonyManager.SIM_STATE_NETWORK_LOCKED:inf.append("需要NetworkPIN解锁");return inf.toString(); 

                   caseTelephonyManager.SIM_STATE_PIN_REQUIRED:inf.append("需要PIN解锁");return inf.toString(); 

                   caseTelephonyManager.SIM_STATE_PUK_REQUIRED:inf.append("需要PUK解锁");return inf.toString(); 

                  caseTelephonyManager.SIM_STATE_READY :break; 

      }

      String phoneNumber =tm.getLine1Number();

      returnphoneNumber;

}

在另外一个activity类里面调用的时候 总是出现进程关闭 无法获取手机信息。后来发现

于是：

1. 给BasicInfo添加一个带参数Context的构造函数：

public BasicInfo (Context context)

{

      this.context =context;

}

2. getPhoneNumber()函数里面改成：

context.getSystemService(Context.TELEPHONY_SERVIC);

3. 在调用类里面 BasicInfo bi = newBasicInfo(this);

bi.getPhoneNumber();
