android 监听来电

获取到管理电话管理对象.

TelephonyManager manager = (TelephonyManager) this
				.getSystemService(Context.TELEPHONY_SERVICE);

通过这个管理对象注册监听

manager.listen(listener, events)

其中listener是具体监听事件

events 设为  PhoneStateListener.LISTEN_CALL_STATE 


新建一个listener实例. 父类为 PhoneStateListener.

重写public void onCallStateChanged(int state, String incomingNumber)

添加自定义逻辑即可，其中

state 有  TelephonyManager.CALL_STATE_RINGING

TelephonyManager.CALL_STATE_IDLE

TelephonyManager.CALL_STATE_OFFHOOK

常用的三种状态...

大概代码..

		manager.listen(new PhoneStateListener() {

			@Override
			public void onCallStateChanged(int state, String incomingNumber) {
				super.onCallStateChanged(state, incomingNumber);
				Log.v("caodongquan", state + "  " + incomingNumber);
				if (state == TelephonyManager.CALL_STATE_RINGING) {
				} else if (state == TelephonyManager.CALL_STATE_IDLE) {
				}
				else if(state == TelephonyManager.CALL_STATE_OFFHOOK)
				{
					
				}
					
			}
		}, PhoneStateListener.LISTEN_CALL_STATE);
