如何修复工作不正常的工作经理班级？

Question

我为工作管理器编写了代码，但运行时什么也没显示，也没有错误。

我经常搜索并阅读有关工作经理的所有问题，但不理解问题。

   OneTimeWorkRequest uploadWorkRequest = new 
   OneTimeWorkRequest.Builder(UploadWorker.class)
   .build();
   WorkManager.getInstance().enqueue(uploadWorkRequest);

这是工人阶级：

   public class UploadWorker  extends Worker {
   Context context;


   @Override
    public Result doWork() {
    Toast.makeText(getApplicationContext(),"es",Toast.LENGTH_LONG).show();
    final AlertDialog.Builder alertDialog=new 
    AlertDialog.Builder(getApplicationContext());
    alertDialog.setTitle("Do You Want to Delete This Record");
    alertDialog.setCancelable(false)
            .setMessage("Click yes to delete")
            .setPositiveButton("Yes", new 
    DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                }
            }).setNegativeButton("No", new 
    DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });
    AlertDialog alertDialog1=alertDialog.create();
    alertDialog1.show();

    return Result.SUCCESS;
   }


   }

您正在滥用WorkManager；您不应将其用于尝试中。尝试将doWork方法中的代码移动到片段或活动中。
