Android 监听来电状态

一、需要权限

注意：
1、两个权限都需要动态申请
2、测试手机是 Android14，运行正常，其他的版本没测试

• Manifest.permission.READ_PHONE_STATE（没有此权限会崩溃）
• Manifest.permission.READ_CALL_LOG （没有此权限回调方法不会触发，如下）

   TelephonyManager.CALL_STATE_IDLE -> Log.e("监听来电", "手机状态：空闲状态") //这个倒是会触发，在注册的时候
   TelephonyManager.CALL_STATE_RINGING -> Log.e("监听来电", "手机状态：来电话状态") //不会触发
   TelephonyManager.CALL_STATE_OFFHOOK -> Log.e("监听来电", "手机状态：接电话状态") //不会触发

二、完整代码

   val telephonyManager = getSystemService(TELEPHONY_SERVICE) as TelephonyManager
   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
       // Android 12 及以上
       val listener = MyCallStateListener()
       telephonyManager.registerTelephonyCallback(mainExecutor, listener)
   } else {
       val listener = MyPhoneStateListener()
   }

    @RequiresApi(Build.VERSION_CODES.S)
    private inner class MyCallStateListener : TelephonyCallback(),
        TelephonyCallback.CallStateListener {
        override fun onCallStateChanged(state: Int) {
            when (state) {
                TelephonyManager.CALL_STATE_IDLE -> Log.e("监听来电", "手机状态：空闲状态")
                TelephonyManager.CALL_STATE_RINGING -> Log.e("监听来电", "手机状态：来电话状态")
                TelephonyManager.CALL_STATE_OFFHOOK -> Log.e("监听来电", "手机状态：接电话状态")
            }
        }
    }

    private inner class MyPhoneStateListener : PhoneStateListener() {
        override fun onCallStateChanged(state: Int, phoneNumber: String?) {
            when (state) {
                TelephonyManager.CALL_STATE_IDLE -> Log.e("监听来电", "手机状态：空闲状态")
                TelephonyManager.CALL_STATE_RINGING -> Log.e("监听来电", "手机状态：来电话状态")
                TelephonyManager.CALL_STATE_OFFHOOK -> Log.e("监听来电", "手机状态：接电话状态")
            }
            super.onCallStateChanged(state, phoneNumber)
        }
    }

参考

Android 12以上TelephonyManager TelephonyCallback onCallStateChanged 方法不会被调用
