如何从来电中获取电话号码？

Question

在Android中有来电时如何获取电话号码？

Answer 1

做一个Broadcast receiver发言权ServiceReceiver分配其清单行动.

<receiver android:name=".ServiceReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.PHONE_STATE" />
    </intent-filter>
</receiver>

添加PhoneStateListener到TelephonyManager,PhoneStateListener具有覆盖onCallStateChanged()Incoming number参数.而已.

ServiceReceiver.Java

public class ServiceReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(final Context context, Intent intent) {
        TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        telephony.listen(new PhoneStateListener(){
            @Override
            public void onCallStateChanged(int state, String incomingNumber) {
                super.onCallStateChanged(state, incomingNumber);
                System.out.println("incomingNumber : "+incomingNumber);
            }
        },PhoneStateListener.LISTEN_CALL_STATE);
    }
}

以下解决方案帮助我检索传入和传出的电话号码。

清单中包含的内容：

1) 权限：

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

2）广播接收器：

<receiver android:name=".AnswerCallBroadcastReceiver">
        <intent-filter> 
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
</receiver>

包含在 BroadcastReceiver 类中的内容：

    public class AnswerCallBroadcastReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context arg0, Intent arg1) {

            if(arg1.getAction().equals("android.intent.action.PHONE_STATE")){

                String state = arg1.getStringExtra(TelephonyManager.EXTRA_STATE);

                if(state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){
                    Log.d(TAG, "Inside Extra state off hook");
                    String number = arg1.getStringExtra(TelephonyManager.EXTRA_PHONE_NUMBER);
                    Log.e(TAG, "outgoing number : " + number);              
                }       

                else if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)){   
                    Log.e(TAG, "Inside EXTRA_STATE_RINGING");
                    String number = arg1.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
                    Log.e(TAG, "incoming number : " + number);
                }
                else if(state.equals(TelephonyManager.EXTRA_STATE_IDLE)){
                    Log.d(TAG, "Inside EXTRA_STATE_IDLE");
                }   
            }   
        }
    }
