可能重复:
我的Asyn类是一个单独的类文件。
public class AdamTask extends AsyncTask<String, Void, String>{
public void showToast(final String toast)
{
runOnUiThread(new Runnable() {
public void run()
{
Toast.makeText(context, to
当在super.onPreExecute中重写onPreExecute时,是否必须调用AsyncTask?AsyncTask.onPreExecute和其他方法实际上是做什么的?onPostExecute和onCancelled同样的问题
public class MyAsyncTask extends AsyncTask<Void, Void, Boolean>
{
@Override
protected void onCancelled(Boolean result) {

Class Foo{
public static boolean isAsyncTask1Done;
public static boolean isAsyncTask2Done;
AsyncTask1(); //in onPostExecute make isAsyncTask1Done= true
AsyncTask2(); //in onPostExecute make isAsyncTask2Done= true
//execute the following method after the above 2 complet
在完成List之后,我有6种不同类型的AsyncTask结果。List的结果应该返回给Activity。例如:List<A>、List<B>、List<C>、List<D>、List<E>,最后还有List<F>。
这是我的AsyncTask
public class myAsync extends AsyncTask<String, String, List> {
private List resultList;
@Override
protected List doInBackg
云函数返回其承诺后,能安全地执行异步吗?考虑以下模式:
exports.deleteUser = functions.auth.user().onDelete(async (user) => {
const uid = user.uid;
asyncTask1(uid);
asyncTask2(uid); // don't wait for the last task to finish
asyncTask3(uid); // just attempt them all and handle
asyncTask4(uid); // the
