android - 在 android Marshmallow 中请求多个权限时遇到问题

Question

我正在开发一个应用程序，我想在运行时请求多个权限。我的代码对于一个权限运行良好。然而，当我想请求多重许可时，我的代码什么都不做。谁能告诉我我的代码有什么问题吗？

首先检查权限是否已经授予。

在这里您可以检查多个权限。

if (checkForPermission(getActivity(), CAMERA_PERMISSION) && checkForPermission(getActivity(), GALLERY_PERMISSION)) {
      //Permission granted here
      //TODO

    } else {
        requestPermissions(new String[]{CAMERA_PERMISSION, GALLERY_PERMISSION}, 1);
}

checkForPermission 方法。

/***
 * Method is checking permission for Marshmallow
 *
 * @param context
 * @param permission
 * @return
 */
private static boolean checkForPermission(final Context context, String permission) {
    int result = ContextCompat.checkSelfPermission(context, permission);
    //If permission is granted then it returns 0 as result
    if (result == PackageManager.PERMISSION_GRANTED) {
        return true;
    } else {
        return false;
    }
}

onRequestPermissionsResult 方法类似于 onActivityResult。

/***
 * This is call when user allow or deny permissions in the Marshmallow
 *
 * @param requestCode
 * @param permissions
 * @param grantResults
 */
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case 1:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
               //Permission granted here
               //TODO

            }
            break;
    }
}
