I want to update seekBar by seconds. but No matter where I put setProgress code, it isn't working. SetProgress is just working on ButtonClick in this code. I want to make seekbar update by seconds. so I make seekbar function. but it isn't work. If I put seekbar function any places, application would be broken. So I cannot resolve this problem. Please help me...
Kotlinx docs don't seem to cover this, I am wondering if there is a way to write a custom Serializer for an existing class. In my case, I need to serialize PointF and Color. For PointF, I have done this:
object MyPointFAsStringSerializer : KSerializer<MyPointF>
{
override val descriptor: SerialDescriptor =
buildClassSerialDescriptor("Point") {
element<Float>("x")
element<Float>("y")
}
override fun serialize(encoder: Encoder, value: MyPointF) =
encoder.encodeStructure(descriptor) {
encodeFloatElement(descriptor, 0, (value.x))
encodeFloatElement(descriptor, 1, (value.y))
}
override fun deserialize(decoder: Decoder): MyPointF =
decoder.decodeStructure(descriptor) {
var x = -1f
var y = -1f
while (true) {
when (val index = decodeElementIndex(descriptor)) {
0 -> x = decodeFloatElement(descriptor, 0)
1 -> y = decodeFloatElement(descriptor, 1)
CompositeDecoder.DECODE_DONE -> break
else -> error("Unexpected index: $index")
}
}
MyPointF(x, y)
}
}
#Serializable(with = MyPointFAsStringSerializer::class)
class MyPointF()
{
var x: Float = Float.MAX_VALUE
var y: Float = Float.MAX_VALUE
constructor(x: Float, y: Float) : this()
{
this.x = x
this.y = y
}
fun pointF () : PointF = PointF(this.x, this.y)
}
However, this approach is forcing me to go back and forth between PointF and MyPointF. I wondering how I could attach the same serializer to an existing class (i.e., PointF). In Swift, I simply do this by using encodeToString, which practically tells the compiler what to do with this kind of object when serializing. But I can't seem to find a way for Kotlin. Any suggestion would be appreciated.
It's definitely possible to serialize 3rd-party classes with kotlinx serialization. You can find the docs here
object PointFAsStringSerializer : KSerializer<PointF> {
override val descriptor: SerialDescriptor =
buildClassSerialDescriptor("Point") {
element<Float>("x")
element<Float>("y")
}
override fun serialize(encoder: Encoder, value: PointF) =
encoder.encodeStructure(descriptor) {
encodeFloatElement(descriptor, 0, (value.x))
encodeFloatElement(descriptor, 1, (value.y))
}
override fun deserialize(decoder: Decoder): PointF =
decoder.decodeStructure(descriptor) {
var x = -1f
var y = -1f
while (true) {
when (val index = decodeElementIndex(descriptor)) {
0 -> x = decodeFloatElement(descriptor, 0)
1 -> y = decodeFloatElement(descriptor, 1)
CompositeDecoder.DECODE_DONE -> break
else -> error("Unexpected index: $index")
}
}
PointF(x, y)
}
}
fun main() {
println(Json.encodeToString(PointFAsStringSerializer, PointF(1.1f, 2.2f)))
}
I have the following class which I am trying to use to perform calculations between fractions however every now and again i get a division by zero exception from on the simplify function and i cannot work out why it is doing it
public class Fraction {
private int top;
private int bottom;
Fraction(int t, int b) {
top = t;
bottom = b;
simplify();
}
public int getTop() {
return top;
}
public int getBottom() {
return bottom;
}
public void simplify() {
if (bottom % top == 0) {
bottom /= top;
top /= top;
} else {
int divisor = gcd(bottom, top);
top /= divisor;
bottom /= divisor;
}
}
public Fraction add(Fraction f) {
if (bottom == f.getBottom()) {
return new Fraction(top + f.getTop(), bottom);
} else {
return new Fraction(((top * f.getBottom()) + (f.getTop() * bottom)), bottom * f.getBottom());
}
}
public Fraction subtract(Fraction f) {
if (bottom == f.getBottom()) {
return new Fraction(top - f.getTop(), bottom);
} else {
return new Fraction(((top * f.getBottom()) - (f.getTop() * bottom)), bottom * f.getBottom());
}
}
public Fraction multiply(Fraction f) {
return new Fraction(top * f.getTop(), bottom * f.getBottom());
}
private static int gcd(int a, int b) {
if (a == 0 || b == 0) {
return a + b;
} else {
return gcd(b, a % b);
}
}
#Override
public String toString() {
return top + "/" + bottom;
}
}
The statement bottom % top yields a divide by zero error when top is zero.
You can fix it by changing the first line of your simplify() method to this:
if (top != 0 && bottom % top == 0) {
So hi to #ll this is my fist post/question on stackoverflow :D
I need help # following :
So i integrated the Facebook SDk sucessfully in my game but i´dont get the profile picture working ...
So i tryied it oldshool on Facebooks "Tutotial" Way and followed all steps to implement login functions and so on ...
I´ve downloaded the "friendsmash_start" Sample and implemented that Stuff ...
My Main Problem is i don´t get ahead with this problem and can´t figure out what i´m doing wrong so i´m hoping for help.
Here´s the complete Code from the MainMenu Script from the sample which is the only i´ve changed ... like in the tutorial ...
Unity shows me this Error -> "The name 'LoadPicture' does not exist in the current context ... so the errors are on these two parts of code :
"LoadPicture(Util.GetPictureURL("me", 128, 128), MyPictureCallback);" in the "OnLoggedIn" function
"LoadPicture(Util.GetPictureURL("me", 128, 128), MyPictureCallback);" in the "MyPictureCallback" function
I don´t understand it cause i searched myself in the script for this function "LoadPicture" and find nothing that was ... according to the "Tutorial" of facebook here :
https://developers.facebook.com/docs/games/unity/unity-tutorial?locale=de_DE
the function should be there cause they wrote there :
"Take a look at the LoadPicture method also in MainMenu.cs to see how we use the Unity WWW class to load the image returned by the graph API."
But i can´t find it :(
HOPE SOMEONE CAN HELP ME I DON´T GET IT ...
Have that problem unfortunately very long time ... thats enoying. :(

I 'm using Microsoft.Windows.Controls.Ribbon, and i would like save and load QuickAccessToolBar.
How I Can find QuickAccessToolBar items, in ribbon control?
This is my idea to save ribbon QuickAccessToolBar
OnClosing application : Get QuickAccessToolBar items, and locaize on Ribbon items. And then serialize
OnLoad : Read serilize object, and add insert items QuickAccessToolBar
Finally i did it!
I'm based on WPF Ribbon Sample to save/load. It used datacontext to localize control on RibbonControl, and i didn't like, so i isued QuickAccessToolBarId to localize the control.
This is the solution:
- OnClosing Application:
I save QuickAccessToolBar, search items on ribbon control by QuickAccessToolBar, and save path. Note: When item is in application menufirst path is -1.A
- OnLoadApplication:
Load items , and seerch on ribbon control by path.
And this is the code:
RibbonHelper:
class RibbonHelper
{
Ribbon ribbon;
