overriding

问题 I'm trying to develop a complete android login registration system with PHP and MySQL from Android. If user forget his password, a new password will be send to his e-mail. I follow this tutorial. ForgetPassword email = (EditText) findViewById(R.id.forpas); forgetPassword.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if ((name.getText().toString().trim().length() == 0) || (email.getText().toString().trim().length() == 0)) { Toast.makeText

问题 I know how to overwrite C-lib functions in just simple sample. But what I need is IN A REAL PROJECT which has hundreds of files that call fprintf. In each file, there's a "#include < stdio.h >" , and tens or hundreds of calls of fprintf . I wanna make all these fprintf to do my own job. I cannot remove the "stdio.h" and put a "#include < myprint.h >" , where myprint.h defines the real function or macro of fprintf that do my own job. "stdio.h" has many other calls in the project. I want a

问题 This question already has answers here : How to convert an int array to String with toString method in Java [duplicate] (8 answers) Closed 6 years ago . This is how you overload the toString() method: public class Person extends Object { @Override public final String toString() { Gson gson = new GsonBuilder().serializeNulls().create(); return (gson.toJson(this)); } } In this example I get a JSON string when calling the toString() method of Person instead of the default string representation

问题 I have class and interface: public class TestClass : ITestInterface { public int GetStatus() { return -1; } } public interface ITestInterface { int GetStatus(); } and I would like to dynamically create subclass of TestClass which will look like: public class TestClass2 : TestClass { public new int GetStatus() { return base.GetStatus(); } } I have some code which can create subclasses and overrides all virtual methods but when method is virtual final (GetStatus) I'm getting: "Declaration

问题 As a newbie in Scala, I have stumbled on this seemingly easy point of SubClassing and Overriding methods. I have specialized a Set thus: class SpecializedSet [T](s:Int, b: Boolean) (implicit ordering: Ordering [T]) extends TreeSet [T] { override def + (t: T): SpecializedSet [T] = { if (this.isEmpty) { s = s + 1 // I want to add an element to the Set super.+ (t) } .... } At the site of using this class, I do: class Driver { var e = new SpecializedSet [MyEarlierDefinedType](3,false); ...... val

问题 On a HTC Evo running Android 2.3.5, overrriden shouldOverrideUrlLoading() is never called. The exact same code works well on a Samsung Galaxy running Android 2.3.6. so far, I have tried overriding onPageStarted() and onPageFinished() . I do not see the URL in these methods. My intent is to provide custom activities for mailto: and tel: links present in the page. Any ideas on how I can make this work if shouldOverrideUrlLoading() is never hit? I have already looked at similar questions on

问题 I'm 13 and quite new to java. What I can't seem to figure out is how NOT to implement overriding methods in a class from an interface because they are references. I don't want to make a new copy, and I can't just make (insert Class here) extend (the class the interface gets some of its methods from). So I implement it and what do i get? err: The type Threadmanager must implement the inherited abstract method (the method) and then it has a list, one of which says "implement uninherited methods

问题 This starts from a previous question that I asked but I think I know what needs to be done but not the How. I have this block of code that defines a pager in bootstrap and applies the bootstrap style to it: <xp:pager partialRefresh="true" id="pager1" for="repeat1" panelPosition="left" styleClass="bootstrapPager"> <xp:pagerControl type="Previous" id="pagerControl1" styleClass="bootstrapPagerPrevious"> <xp:this.value><![CDATA[«]]></xp:this.value> </xp:pagerControl> <xp:pagerControl type="Group"

问题 I need to override onchange_partner_id function present in sale.order but I'm working on a system that already have a module overriding this function. I tried to write my own onchange_partner_id with similar code : def onchange_partner_id(self, cr, uid, ids, part): res = super(sale_order, self).onchange_partner_id(cr, uid, ids, part) // doing some stuff and adding it to res['value']['myfield'] return res But my function isn't read by OpenERP. So my question is, is it possible to have multiple
