电话状态、电话录音

获得电话状态需要在请电脑文件中添加如下权限
监听电话的步骤：
    说用到主要方法：
void listen(PhoneStateListener listener, int events)
Registers a listener object to receive notification of changes in specified telephony states.
  1. //1、通过服务获得TelePhonemanger
  2. TelePhonemanger tele = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
  3. //2、注册一个电话的监听listener 监听电话状态
  4. telephonyManager.listen(new MyPhoneStateListener(), PhoneStateListener.LISTEN_CALL_STATE);
写一个内部类MyPhoneStateListener 继承与 PhoneStateListener
  1. 	 private class MyListener extends PhoneStateListener{
  2. 		@Override
  3. 		public void onCallStateChanged(int state, String incomingNumber) {
  4. 			if(state==tele.CALL_STATE_RINGING){//来电状态
  5. 				System.out.println("弹出土司------------电话号码归属地");
  6. 				
  7. 			}else if(state==tele.CALL_STATE_OFFHOOK){//接通状态
  8. 				System.out.println("土司关闭");
  9. 			}
  10. 			super.onCallStateChanged(state, incomingNumber);
  11. 		}
  12. 	}
相关实例：
1、电话录音：
  1. public class PhoneService extends Service {
  3. 	private TelephonyManager telephonyManager;
  4. 	//定义一个  录音机
  5. 	private MediaRecorder recorder;  
  6. 	
  7. 	@Override
  8. 	public IBinder onBind(Intent intent) {
  9. 		return null;
  10. 	}
  11. 	
  12. 	@Override
  13. 	public void onCreate() {
  14. 		// 在 把 TelephonyManager 给初始化 
  15. 		telephonyManager  = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
  16. 		/**
  17. 		 * 注册一个电话的监听 
  18. 		 * listener  监听电话状态 
  19. 		 */
  20. 		telephonyManager.listen(new MyPhoneStateListener(), PhoneStateListener.LISTEN_CALL_STATE);
  21. 		
  22. 		super.onCreate();
  23. 	}
  24. 	
  25. 	
  26. 	private class MyPhoneStateListener extends PhoneStateListener{
  27. 		
  28. 		//当电话状态发生改变的时候调用 
  29. 		@Override
  30. 		public void onCallStateChanged(int state, String incomingNumber) {
  31. 			switch (state) {
  32. 			case TelephonyManager.CALL_STATE_IDLE:  // 挂断 或者 未接通
  33. 				System.out.println("判断一下录音机是否开启  如果开启  停止录音");
  35. 				if (recorder!=null) {
  36. 					 recorder.stop(); //停止录
  37. 					 recorder.reset();   // You can reuse the object by going back to setAudioSource() step
  38. 					 recorder.release(); // Now the object cannot be reused
  39. 				}
  40. 				
  41. 				
  42. 				break;
  43. 				
  44. 			case TelephonyManager.CALL_STATE_OFFHOOK:  //接通状态 
  45. 				System.out.println("开始录音");
  46. 				 
  47. 				//开始录
  48. 				recorder.start();   // Recording is now started
  49. 				
  50. 				break;
  51. 				
  52. 				
  53. 			case TelephonyManager.CALL_STATE_RINGING:  //响铃状态
  54. 				
  55. 				System.out.println("准备一个录音机出来");
  56. 				  //初始化 录音机
  57. 				 recorder = new  MediaRecorder();
  58. 				 // 设置音频来源 
  59. 				 recorder.setAudioSource(MediaRecorder.AudioSource.MIC);   // zet  华为   
  60. 				 // 设置音频输出的格式  3gp 
  61. 				 recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
  62. 				 // 设置音频编码方式    
  63. 				 recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
  64. 				 //设置音频保存的路径  
  65. 				 recorder.setOutputFile("/mnt/sdcard/haha.3gp");
  66. 				 //开始准备录 
  67. 				 try {
  68. 					recorder.prepare();
  69. 				} catch (IllegalStateException e) {
  70. 					e.printStackTrace();
  71. 				} catch (IOException e) {
  72. 					e.printStackTrace();
  73. 				}
  74. 				
  75. 				
  76. 				break;
  78. 			default:
  79. 				break;
  80. 			}
  81. 			
  82. 			
  83. 			super.onCallStateChanged(state, incomingNumber);
  84. 		}
  85. 		
  86. 	}
  87. 	
  89. }
注：在清单中需要添加的权限：
  1.   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
  2.     <uses-permission android:name="android.permission.RECORD_AUDIO" />
  3.     <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>


常用到的电话状态：
1、通过系统服务拿到TelephoneManager
  1. TelephonyManager tele = (TelephonyManager) getSystemService(TELEPHONY_SERVICE
2、获得电话的几种常用状态
CALL_STATE_IDLE：表示电话处于闲置状态
CALL_STATE_OFFHOOK：表示电话处于接通状态
CALL_STATE_RINGING：表示电话处于响铃状态
3、获得当前电话状态：
  1. int state = tele.getCallState();



常用api预览：
String ACTION_PHONE_STATE_CHANGED Broadcast intent action indicating that the call state (cellular) on the device has changed.
int CALL_STATE_IDLE Device call state: No activity.
int CALL_STATE_OFFHOOK Device call state: Off-hook.
int CALL_STATE_RINGING Device call state: Ringing.
int DATA_ACTIVITY_DORMANT Data connection is active, but physical link is down
int DATA_ACTIVITY_IN Data connection activity: Currently receiving IP PPP traffic.
int DATA_ACTIVITY_INOUT Data connection activity: Currently both sending and receiving IP PPP traffic.
int DATA_ACTIVITY_NONE Data connection activity: No traffic.
int DATA_ACTIVITY_OUT Data connection activity: Currently sending IP PPP traffic.
int DATA_CONNECTED Data connection state: Connected.
int DATA_CONNECTING Data connection state: Currently setting up a data connection.
int DATA_DISCONNECTED Data connection state: Disconnected.
int DATA_SUSPENDED Data connection state: Suspended.
