The difference is that the second line refers to menu to find its item and the first finds view in activity layout Doc for the first line: https://developer.android.com/reference/android/app/Activity.html#findViewById(int) Doc for the second line: https://developer.android.com/reference/android/view/Menu.html#findItem(int) solved why use menu.findItem() and not findViewByID alone?
It is simple mathematics: You have a numberOfInstallments, the totalAmount and an initialInstallment. First get the left over amount with totalAmount – initialInstallment. Next divide by numberOfInstallments. In Java is becomes something like this: int totalAmount = 15000; int initialInstallment = 5000; int numberOfInstallments = 5; // Calculate the height of each installment int installment … Read more
This can be put into one line in several ways. Without changing your code you could just remove the newline and indent: with open(‘output.txt’, ‘w’) as f: for item in winapps.list_installed(): print(item, file=f) Or just using unpacking and print formatting: with open(‘output.txt’, ‘w’) as f: print(*winapps.list_installed(), sep=”\n”, file=f) Which can also be done in one … Read more
I have taken the first permutation algorithm I found in wikipedia and implemented it in Delphi (2009); I hope that is what you are looking for: type TIntegerArray = array of Integer; procedure Permutation(K: Integer; var A: TIntegerArray); var I, J: Integer; Tmp: Integer; begin for I:= 2 to Length(A) do begin J:= K mod … Read more
You’re looking for all posts where post_status = publish and post_type = post. The WordPress posts table also includes pages, revisions, and attachments … that’s why you need to be specific. If you’re using the default database scheme (with wp_ as a table prefix), the following query will give you what you need: SELECT post_title … Read more
The cookies in your sample are Google’s web analytics cookies, and they’re set via Javascript. Unless the crawler you’re writing can execute Javascript, those cookies will simply NEVER get set in the crawler. What you see in your browser is utterly irrelevant for fixing this – it’s what the crawler sees, gets, and can do … Read more
That is why storing base64 encoded serialized data in the database is extremely bad idea. You have to redesign your database, getting rid of base64_encode and serialized data. While using base64 with database makes absolutely no sense by any means, storing serialized data in the database is like mending an electronic device with stone hammer. … Read more
I am not exactly sure what you are trying to do, but you could try something like this (since you are alluding to passing DIRECTLY from Java to Javascript) … (only applies to JDK1.6+) … ScriptEngineManager mgr = new ScriptEngineManager(); ScriptEngine engine = mgr.getEngineByName(“JavaScript”); String javascript = “3+2*(4+5)”; System.out.println(engine.eval(javascript)); p.s. Make sure you have previously … Read more
+= Symbol is used for the appending text . ADD – AND assignment operator, It adds right operand to the left operand and assign the result to left operand 5 solved didn’t know symbol “+=” in android [closed]
This isn’t elegant, but you could strip line endings, then replace the spaces and tabs: askuser = askuser.strip().replace(‘ ‘,”).replace(‘\t’,”) solved How do I remove all white space in any given input? [closed]
You should have expanded a little bit on what you said, your question was very confusing, you should have also mention you were using regex. Try this: ^[A-Za-z0-9.\\-]+.[A-Za-z0-9.\\-]+\\.[A-Za-z]{2,4}$ 0 solved how can validate website address in android application [closed]
Use the boolean-returning function headers_sent to determine if headers have been fully sent (implying that some content has also been sent too). solved How can I know the body content is outputted (then cannot use the header function)? [closed]
The usual way to post something on Facebook or Twitter is to use their APIs. They don’t provide any service that takes emails and creates a status or a tweet. The reason is trivial: email is very unsecure, you can’t identify the originator of an email and such a service would lead to massive spamming. … Read more
*pointer nominally requires a fetch from memory, and that is generally the most expensive of the operations shown in your code. If we assume your code is compiled directly to the obvious assembly corresponding to the operations as they are described in C’s abstract machine, with no optimization, modern CPUs for desktop computers are typically … Read more
I solved this problem by using the Dispatcher: private void grid_SizeChanged(object sender, SizeChangedEventArgs e) { //text.Text = grid.Width.ToString(); Dispatcher.BeginInvoke(new Action(() => text.Text = grid.Width.ToString())); } Thank you all for “help” and negative rating. solved .NET bug.
