要監聽android打電話和接電話，只需下面2步驟
1.第一步，寫一個Receiver繼承自BroadcastReceiver
public class PhoneStatReceiver extends BroadcastReceiver{
private static final String TAG = "PhoneStatReceiver";
// private static MyPhoneStateListener phoneListener = new MyPhoneStateListener();
private static boolean incomingFlag = false;
private static String incoming_number = null;
@Override
public void onReceive(Context context, Intent intent) {
//如果是撥打電話
if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
incomingFlag = false;
String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i(TAG, "call OUT:"+phoneNumber);
}else{
//如果是來電
TelephonyManager tm =
(TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
switch (tm.getCallState()) {
case TelephonyManager.CALL_STATE_RINGING:
incomingFlag = true;//標識當前是來電
incoming_number = intent.getStringExtra("incoming_number");
Log.i(TAG, "RINGING :"+ incoming_number);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
if(incomingFlag){
Log.i(TAG, "incoming ACCEPT :"+ incoming_number);
}
break;
case TelephonyManager.CALL_STATE_IDLE:
if(incomingFlag){
Log.i(TAG, "incoming IDLE");
}
break;
}
}
}
}
第二步：在AndroidManifest.xml，配置寫好的Receiver，並攔截相應的BroadCastAction，
另外注意加上相應的許可權。
<receiver android:name=".filter.PhoneStatReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE"/>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>
