Android来电号码获取代码
Manifest里要加这个权限

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

因为android没有直接挂断电话的API，所以需要导入两个AIDL包：
android.telephony和com.android.internal.telephony

下面代码中的number就是呼入的号码
TelephonyManager telephone = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
PhoneStateListener listener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String number) {
if("关闭".equals(check)){
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
break;
}
}else{
if ("静音".equals(phone)) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
break;
}
}else if ("和谐模式".equals(phone)) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
try {
Method method = Class.forName(
"android.os.ServiceManager").getMethod(
"getService", String.class);
IBinder binder = (IBinder) method.invoke(null,
new Object[] { TELEPHONY_SERVICE });
ITelephony telephony = ITelephony.Stub
.asInterface(binder);
telephony.endCall();
} catch (Exception e) {
e.printStackTrace();
}
break;
}
}else{
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
break;
case TelephonyManager.CALL_STATE_RINGING:
try {
Method method = Class.forName(
"android.os.ServiceManager").getMethod(
"getService", String.class);
IBinder binder = (IBinder) method.invoke(null,
new Object[] { TELEPHONY_SERVICE });
ITelephony telephony = ITelephony.Stub
.asInterface(binder);
telephony.endCall();
} catch (Exception e) {
e.printStackTrace();
}

listNum = (List<PersonNumber>) dbHelper
.findAllNumber(PersonNumber.TABLENAME);
for (int i = 0; i < listNum.size(); i++) {
if (listNum.get(i).getNumber().equals(number)) {

String time = sdf.format(new Date());
blackNumber = new PhoneBlackNumber(listNum
.get(i).getNumber(), "未知", time);
dbHelper.insertPersonNumber(blackNumber);

Intent intt = new Intent();
intt.setAction(PhoneReceiver.PHONE_RECEIVER_ACTION);
sendBroadcast(intt);
}
}
break;
}
}
}

super.onCallStateChanged(state, number);
}
};
telephone.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);

楼主的需求很简单，只要求获取来电号码，没有其他操作……

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;



import android.app.Service;

import android.telephony.TelephonyManager;

import java.lang.reflect.Method;

import android.widget.Toast;





public class PhoneListen extends BroadcastReceiver{



    private static boolean mIncomingFlag = false;

    private static String mIncomingNumber = null;



    @Override

    public void onReceive(Context context, Intent intent) {

        //Dial number;

        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {

            ;//这个是拨号的时候采用的到的，所以这里没用

        } else {

            //Get call;

            TelephonyManager tManager = (TelephonyManager) context

                    .getSystemService(Service.TELEPHONY_SERVICE);

            switch (tManager.getCallState()) {

                //有电话打进来

                case TelephonyManager.CALL_STATE_RINGING:

                    //mIncomingNumber就是来电号码

                    mIncomingNumber = intent.getStringExtra("incoming_number");

                    Toast.makeText(context, mIncomingNumber,

                            Toast.LENGTH_LONG).show();



               



                    break;

               default:break;

            }

        }

    }



}
