在Activity中触发的onRequestPermissionsResult（）未分段

Question

我正在我的Fragment中调用requestPermissions()，这是该函数的片段实现（我没有调用activity.requestPermission()）。我的上级活动和片段中都有onRequestPermissionsResult()。从Fragment调用权限后，它会触发错误的onRequestPermissionsResult()。为什么会发生

片段请求权限：

override fun onOptionsItemSelected(item: MenuItem?): Boolean {
    return if (item?.itemId == R.id.createNewChat) {
        if (activity.hasReadContactsPermission()) {
            startActivity(Intent(activity, PhoneBookActivity::class.java))
        } else {
            requestPermissions(
                arrayOf(Manifest.permission.READ_CONTACTS),
                Constants.MY_PERMISSIONS_READ_CONTACT
            )
        }
        true
    } else {
        super.onOptionsItemSelected(item)
    }
}

片段onRequestPermissionsResult()：

override fun onRequestPermissionsResult(
    requestCode: Int,
    permissions: Array<String>,
    grantResults: IntArray
) {
    when (requestCode) {
        Constants.MY_PERMISSIONS_READ_CONTACT -> {
            if(grantResults[0] == PackageManager.PERMISSION_GRANTED){
                startActivity(Intent(activity, PhoneBookActivity::class.java))
            }
        }
    }
}

活动onRequestPermissionsResult()：

override fun onRequestPermissionsResult(
    requestCode: Int,
    permissions: Array<String>,
    grantResults: IntArray
) {
    when (requestCode) {
        Constants.MY_PERMISSIONS_MULTIPLE -> {
            if (grantResults.all { it == PackageManager.PERMISSION_GRANTED }) {
                startService(Intent(this, RegisterDeviceTokenTask::class.java))
                if (smartServiceBound) {
                    smart113Service!!.onMainActivityStarted()
                } else {
                    requestPermissionsUtil(
                        requiredPermissions,
                        Constants.MY_PERMISSIONS_MULTIPLE
                    )
                }
            }
        }
    }
}

我可能会在Activity中侦听此权限检查，但是当requestCode从Fragment移到Activity时，requestCode会发生变化，而我不想弄乱它。

在片段中触发onRequestPermissionResult()的解决方案是什么？
