android - AsyncTask 更新在 android 的其他类中调用的 ui 计数器

Question

我需要将文件上传计数动态更新到在其他类方法中调用的 Ui 进度条中。AsyncTask doInBackground() 和 myClass.uploadFiles() 之间如何通信。请帮我

这是活动

  public class MyActivity extends AppCompatActivity {

        private ProgressDialog dialog = null;
        String status;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_file);
            
              CounteTask task = new CounteTask();
              task.execute();
            
        }

            private class CounteTask extends AsyncTask<String, Integer, Void> {


                @Override
                protected Void doInBackground(String... params) {

                    try {

                        status = myClass.uploadFiles(MyActivity.this);
                    } catch (Exception e) {

                        dialog.dismiss();
                    }

                    return null;
                }

                @Override
                protected void onPostExecute(Void resultGetlogin) {

                    dialog.dismiss();
                }

                protected void onPreExecute() {
                    dialog = ProgressDialog.show(Sync_Records.this, "", "Please wait, file count..");
                }

                protected void onProgressUpdate(Integer... values) {
                    
                }

            }
  }

MyClass.java 从这里需要更新 ui 线程。

        public void MyClass{
        
            public static String uploadFiles(Context context) {
            
                  for (count=0 ; count <= 10; count++) {
                     try {
                            upload(count);                            //need to show each count of file which is currently uploading

                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
            
            }
            return status;
        
        }
