similar this thread , i'm having delay in click response of view inside listview's row. also, click listener fired when view outside listview gained focus. my question is, there other way solve this, apart ditching listview altogether, suggested on link above? i had come same issue , solved of others. it seems used hash array save listview rows in order avoid inflate new view multiple times while implementing getview() method. however using hash array make listener's status mess cause problem described. so delete hash array , return row view in getview() method.

say given array, , function called replace : void replace(from, to, items[]) whose job replace array elements in range [from, to) elements in items . i'll assume maximum size of array known beforehand, can ensure array never overflow. my question is, if given list of replacements (e.g. elements of form (from, to, items) ), possible me obtain final resulting array faster time complexity performing each operation sequentially? in other words, there advantage knowing sequence of operations beforehand, or no better being given each operation 1 one (in terms of asymptotic time complexity)? note: seems question confusing; did not intend imply number of elements replacing given range same size of range! fewer or more, causing shifting, , point of question was ask if knowing them beforehand avoid work shifting in worst case. i think may not finding, using rope can shorten time-complexity. provides operation on string concat without "shift"ing actual a...

gae doesn't allow read/write file system, django's filefield (or imagefield) using (via filesystemstorage class). i thinking implementing custom django storage, gae blobstore seems incompatible django requirements. specifically, gae blobstore assume direct upload client store, while django custom storage need implement _save(name, content) method. as far can see no 1 refer missing implementation. there custom storage projects out there (most notably: django-storages on bitbucket), implementations s3, windows azure, dozens of other backend, nothing google. what direction should take have filefield in model, hosted on google app engine? to clarify: - i'm using stocked, trunk, 1 uses google cloud sql django comes google sdk - i'm not using django nonrel. - i've followed django guide google documentation. blobstore support writing files feature. see writing file blobstore . therefore possible implement _save(name, content) blobstore now. another...

i having bit of trouble wrapping head around this, thought ask it.. i have code: $x="string"; var_dump($x==0); //says true var_dump($x==true); //says true var_dump(true==0); //says false what understand is: in 1, `string` gets converted number, becomes `0` condition true in 2, `string` value, condition true in 3, `true` not equal `0` condition false individually make sense, in sequence don't! have heard many people because conditional operator in php not transient . can explain means, , how make sense of this? why in world wouldn't make sense? never change value of x , statements dependent on original value of x "string". you assuming x changed 0 in first var_dump not. merely compared 0/false. statement perform variable change think happening: var_dump(($x = 0) == 0); or: var_dump(($x = false) == 0);
