Android 在检查并请求权限后继续

我知道关于检查和请求许可以及处理他们的回复有很多问题得到解答，我对此很清楚。但我有点困惑的是，如果我们正在检查两个不同事物的相同权限，那么在授予权限后我们如何继续任务？

例如，我有 recycleView，在我的适配器中我有两个按钮的代码，一个用于保存文件，另一个用于保存并打开活动以与其他应用程序共享该文件。

MyRecycleAdapter {

Context context:

save.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View view) {
           if(checkPermission()) {
               have permission
               save file to disk
          } else {
              requestPermission
               save file to disk
           }  
     }
});
share.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View view) {
           if(checkPermission()) {
               have permission
               save file to disk
               open share activity using (context)
          } else {
              requestPermission
               save file to disk
              open share activity using (context)
           }  
     }
});

}

使用不同的请求代码来控制授予权限后发生的情况：

final int SAVE = 1;
final int SAVE_AND_SHARE = 2;

if (ActivityCompat.checkSelfPermission(this,
  Manifest.permission.WRITE_EXTERNAL_STORAGE)
  != PackageManager.PERMISSION_GRANTED
) {
  ActivityCompat.requestPermissions(
    this,
    new String[]{
      android.Manifest.permission.WRITE_EXTERNAL_STORAGE
    },
    [either SAVE or SAVE_AND_SHARE]);
} else {
  //permission is already granted, continue
}


@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] 
  grantResults) {
  if (requestCode == SAVE) {
    if (grantResults.length > 0
      && grantResults[0] == PackageManager.PERMISSION_GRANTED
    ) {
      //save
    } else {
      //permission was denied
    }
  } else if (requestCode == SAVE_AND_SHARE) {
    if (grantResults.length > 0
      && grantResults[0] == PackageManager.PERMISSION_GRANTED
    ) {
      //save and share
    } else {
      //permission was denied
    }
  }
}
