Question

我想使用以下代码检查应用程序启动时的所有权限：

public void checkPermissions() {
    List<String> permissions = new ArrayList<>();

    permissions.add(Manifest.permission.INTERNET);
    permissions.add(Manifest.permission.ACCESS_FINE_LOCATION);
    permissions.add(Manifest.permission.ACCESS_COARSE_LOCATION);


    List<String> deniedPermissions = new ArrayList<>();

   for (String permission : permissions) {
       if (ContextCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_DENIED) {
            deniedPermissions.add(permission);
       }
   }

   if (deniedPermissions.size() > 0) {
       Activity activity = (Activity) context;
       ActivityCompat.requestPermissions(activity, deniedPermissions.toArray(new String[deniedPermissions.size()]), PERMISSIONS);
   }
}

如果用户接受权限，则会调用此代码：

 @Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case MainController.PERMISSIONS:
            boolean allPermissionsGranted = true;

            for (int grantResult : grantResults) {
                if (grantResult == PackageManager.PERMISSION_DENIED)
                    allPermissionsGranted = false;
            }

            if (!allPermissionsGranted) {
                View view = findViewById(R.id.content_main);
                Snackbar snackBar = Snackbar.make(view, "YOLO", Snackbar.LENGTH_LONG);
            }
            break;
    }
}

但如果他拒绝，则没有任何反应，onRequestPermissionsResult函数永远不会被调用。

我做错了吗？

好的，我通过实现接口ActivityCompat.OnRequestPermissionsResultCallback

解决了这个问题

用户拒绝权限时未调用onRequestPermissionsResult
