android - 如何识别用户是否在 Android 上的权限对话框之外单击

Question

自从在 Android 11 ( https://developer.android.com/about/versions/11/privacy/location ) 上引入新的位置权限更改后，需要更加谨慎地处理权限。我们现在只能两次请求后台位置权限

我想根据用户的位置权限状态向用户显示一个对话框。

问题是系统处理对话框外的点击与拒绝权限相同，但它显然不计入 PermissionsUtil.shouldShowRequestStoragePermissionRationale 限制。因此很难区分用户处于哪种状态。

我最初的问题是:如何处理这种特定情况？

但我想更有用的是一般性问题:
如何识别用户是在系统权限对话框之外按下还是直接拒绝了权限？。

我是这样解决的:

private val btRequestPermissionLauncher =
    registerForActivityResult(ActivityResultContracts.RequestMultiplePermissions()) { permissions ->
        val allPermissionsGranted = permissions.values.none { !it }
        if (allPermissionsGranted) {
            callback?.invoke().apply { this@PermissionActivity.callback = null }
        } else if (Manifest.permission.BLUETOOTH_CONNECT in requiredPermissions || Manifest.permission.ACCESS_FINE_LOCATION in requiredPermissions) {
            if (!shouldShowRequestPermissionRationale(Manifest.permission.BLUETOOTH_CONNECT) && !shouldShowRequestPermissionRationale(Manifest.permission.ACCESS_FINE_LOCATION) && (this.getPreferenceBoolean("NEVER_SHOW_AGAIN", false) || shouldShowRationaleBefore)) {
                this.getPreferenceBoolean("NEVER_SHOW_AGAIN", true)
                //A dialog box with GO TO SETTING button
            } else {
                shouldShowRationaleBefore = true
                requestBluetoothPermissions()
            }
        } else
            requestBluetoothPermissions()

    }


private var shouldShowRationaleBefore = false
protected fun requestBluetoothPermissions(callBack: (() -> Unit)? = null) {
    this.callback = callBack

    when {
        areAllPermissionsGranted() -> {
            callBack?.invoke()
        }
        shouldShowRequestPermissionRationale(Manifest.permission.BLUETOOTH_CONNECT) -> {
            //A dialog box with CONTINUE button and callBack to btRequestPermissionLauncher.launch(...) 
        }
        shouldShowRequestPermissionRationale(Manifest.permission.ACCESS_FINE_LOCATION) -> {
            //A dialog box with CONTINUE button and callBack to btRequestPermissionLauncher.launch(...) 
        }
        !areAllPermissionsGranted() -> {
            if (!shouldShowRationaleBefore)
                btRequestPermissionLauncher.launch(requiredPermissions)
            else { 
                 private var shouldShowRationale = false
                //A dialog box with CONTINUE button and callBack to btRequestPermissionLauncher.launch(...) 
                //This is where the click outside the permission dialog box is handled
            }
        }

    }
}
