Android監聽來電和去電

Android中監聽來電和去電，這種功能的實現也許會在一些項目中經常實現，尤其一些防盜軟件，這裡為大家分享一下很不錯的Android監聽來電和去電的源碼：

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

1. import android.app.Service;
2. import android.content.BroadcastReceiver;
3. import android.content.Context;
4. import android.content.Intent;
5. import android.telephony.TelephonyManager;
6. import android.util.Log;
8. public class PhoneStateBroadCastReceiver extends BroadcastReceiver
9. {
10. private static final String TAG = "PhoneStateBroadCastReceiver";
12. private static boolean mIncomingFlag = false;
13. private static String mIncomingNumber = null;
15. @Override
16. public void onReceive(Context context, Intent intent)
17. {
18. // 如果是撥打電話
19. if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL))
20. {
21. mIncomingFlag = false;
22. String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
23. Log.i(TAG, "call OUT:" + phoneNumber);
24. } else
25. {
26. // 如果是來電
27. TelephonyManager tManager =
28. (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE);
29. switch (tManager.getCallState())
30. {
31. case TelephonyManager.CALL_STATE_RINGING:
32. mIncomingNumber = intent.getStringExtra("incoming_number");
33. Log.i(TAG, "RINGING :" + mIncomingNumber);
34. break;
35. case TelephonyManager.CALL_STATE_OFFHOOK:
36. if (mIncomingFlag)
37. {
38. Log.i(TAG, "incoming ACCEPT :" + mIncomingNumber);
39. }
40. break;
41. case TelephonyManager.CALL_STATE_IDLE:
42. if (mIncomingFlag)
43. {
44. Log.i(TAG, "incoming IDLE");
45. }
46. break;
47. }
48. }
49. }
51. }

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權限：

1. <receiver android:name=".broadcase.PhoneStateBroadCastReceiver">
2. <intent-filter>
3. <action android:name="android.intent.action.PHONE_STATE"/>
4. <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
5. </intent-filter>
6. </receiver>
7. <uses-permission android:name="android.permission.READ_PHONE_STATE" />
8. <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
