Android广播接实现监听电话状态（电话的状态，拦截）

3：编写广播的实现类 这里需要继承BroadcastReceiver 实现onReceive()方法

程序的源代码如下：

package com.zyw.broadcastsendsms;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;
public class PhoneBroadcastReceiver extends BroadcastReceiver {
private static final String TAG = "message";
private static boolean mIncomingFlag = false;
private static String mIncomingNumber = null;
@Override
public void onReceive(Context context, Intent intent) {
// 如果是拨打电话
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
mIncomingFlag = false;
String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i(TAG, "call OUT:" + phoneNumber);
} else {
// 如果是来电
TelephonyManager tManager = (TelephonyManager) context
.getSystemService(Service.TELEPHONY_SERVICE);
switch (tManager.getCallState()) {
case TelephonyManager.CALL_STATE_RINGING:
mIncomingNumber = intent.getStringExtra("incoming_number");
Log.i(TAG, "RINGING :" + mIncomingNumber);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
if (mIncomingFlag) {
Log.i(TAG, "incoming ACCEPT :" + mIncomingNumber);
}
break;
case TelephonyManager.CALL_STATE_IDLE:
if (mIncomingFlag) {
Log.i(TAG, "incoming IDLE");
}
break;
}
}
}
/*@Override
public void onReceive(Context context, Intent intent) {
String number = getResultData();
if("5556".equals(number)){
setResultData(null);//挂断
}else{
number = "12593"+ number; //其他，则加区号
setResultData(number);
}
}*/
}
