Cannot resolve constructor while set Animation - animation

Here is the code in the class,I am using libgdx to develop a game but i don't how to solve the error about
(Cannot resolve constructor 'Sprite(java.lang.Object)' )in the render.
public class GamePage implements Screen{
private static final float FRAME_DURATION = 1.0f / 15.0f;
private SpriteBatch batch;
private TextureAtlas boxAtlas;
private Animation boxAnim;
private float boxTime;
private Sprite spritebox;
#Override
public void show() {
boxAtlas = new TextureAtlas(Gdx.files.internal("ybanim.pack"));
boxAnim = new Animation(FRAME_DURATION, boxAtlas.getRegions(), Animation.PlayMode.NORMAL);
batch = new SpriteBatch();
}
#Override
public void render(float delta) {
Gdx.gl.glClearColor(1, 1, 1, 0);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
boxTime += delta;
spritebox = new Sprite(boxanim.getKeyFrame(boxTime, true));
spritebox.setPosition(0,0);
batch.begin();
spritebox.draw(batch);
batch.end();
}

boxanim.getKeyFrame(boxTime, true) returning Object and no constructor available in Sprite class that can take Object as parameter.
From gdx version 1.9.5 Animation class is now generic, there is a pull request for the same. so declare your animation in this way :
Animation<TextureRegion> boxAnim;

Unity3d resize panel with mouse from bottom right corner

I want to resize a UI panel with the mouse. I don't know how to do this myself. How can I do this?
Kind of a short question, so I'm not sure if you want anything extremely specific, but this is something I found on the Unity Tutorials Website. Seems to be what you're looking for:
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;
public class ResizePanel : MonoBehaviour, IPointerDownHandler, IDragHandler {
public Vector2 minSize;
public Vector2 maxSize;
private RectTransform rectTransform;
private Vector2 currentPointerPosition;
private Vector2 previousPointerPosition;
void Awake () {
rectTransform = transform.parent.GetComponent<RectTransform>();
}
public void OnPointerDown (PointerEventData data) {
rectTransform.SetAsLastSibling();
RectTransformUtility.ScreenPointToLocalPointInRectangle (rectTransform, data.position, data.pressEventCamera, out previousPointerPosition);
}
public void OnDrag (PointerEventData data) {
if (rectTransform == null)
return;
Vector2 sizeDelta = rectTransform.sizeDelta;
RectTransformUtility.ScreenPointToLocalPointInRectangle (rectTransform, data.position, data.pressEventCamera, out currentPointerPosition);
Vector2 resizeValue = currentPointerPosition - previousPointerPosition;
sizeDelta += new Vector2 (resizeValue.x, -resizeValue.y);
sizeDelta = new Vector2 (
Mathf.Clamp (sizeDelta.x, minSize.x, maxSize.x),
Mathf.Clamp (sizeDelta.y, minSize.y, maxSize.y)
);
rectTransform.sizeDelta = sizeDelta;
previousPointerPosition = currentPointerPosition;
}
}

How to smoothly animate an ImageView with effects applied

I have created a CollapsablePane which shows an EffectImageView as collapsableContent, and a Node as mainContent. The EffectImageView consists of two layered ImageViews, the bottom one having an BoxBlur effect applied on it.
When there is a ScrollEvent on the mainContent the collapsableContent will be animated accordingly by setTranslateY.
With a BoxBlur effect applied, the translation of the lower part of the collapsableContent is very unsmooth, while it is absolutely smooth without the effect.
Is there a possibility to improve the transition performance?
public class EffectImageView extends Pane {
private ImageView img;
private ImageView imgEffect;
private Rectangle clipTop;
private Rectangle clipBottom;
private DoubleProperty imageEffectHeight = new SimpleDoubleProperty();
private double effectOffset;
public EffectImageView() {
img = createCachedImageView();
imgEffect = createCachedImageView();
imgEffect.imageProperty().bind(img.imageProperty());
imgEffect.fitWidthProperty().bind(img.fitWidthProperty());
imgEffect.fitHeightProperty().bind(img.fitHeightProperty());
clipTop = new Rectangle();
clipTop.widthProperty().bind(img.fitWidthProperty());
clipTop.heightProperty().bind(img.fitHeightProperty().subtract(imageEffectHeight).subtract(translateYProperty()));
clipBottom = new Rectangle();
clipBottom.widthProperty().bind(img.fitWidthProperty());
clipBottom.heightProperty().bind(imageEffectHeight);
clipBottom.translateYProperty().bind(heightProperty().subtract(imageEffectHeight).subtract(translateYProperty()));
img.setClip(clipTop);
imgEffect.setClip(clipBottom);
getChildren().addAll(img, imgEffect);
}
private ImageView createCachedImageView() {
ImageView img = new ImageView();
img.setCache(true);
img.setCacheHint(CacheHint.SPEED);
return img;
}
public final ObjectProperty<Image> imageProperty() {
return img.imageProperty();
}
public final Image getImage() {
return img.getImage();
}
public final void setImage(Image image) {
img.setImage(image);
}
public void setImageEffect(Effect effect) {
imgEffect.setEffect(effect);
}
public final DoubleProperty imageEffectHeightProperty() {
return imageEffectHeight;
}
public void setEffectOffset(double offset) {
effectOffset = offset;
}
#Override
protected void layoutChildren() {
double w = getWidth();
double h = getHeight();
img.relocate(-effectOffset, 0);
imgEffect.relocate(-effectOffset, 0);
img.setFitWidth(w + effectOffset * 2);
img.setFitHeight(h);
}
}

Can't create animation in libgdx

this is my code and then i try to launch it i get

How to fix this? And also when i use TextureRegion[][] temp = new TextureRegion.split(background_main, 128, 72);Eclipse says
TextureRegion.split cannot be resolved to a type
TextureRegion.split cannot be resolved to a type
You are getting an error because you are using keyword new
Do something like this and your error will be fixed
TextureRegion[][] tmp = TextureRegion.split(background_main, background_main.getWidth()/TOTAL_COLS, background_main.getHeight()/TOTAL_ROWS);
Your second error is because you have commented the line where you are initializing your array, you need to uncomment this
//background_textures = new TextureRegion[3];

Libgdx V1.3.1 Splash Screen Tween Error: Exception in thread "LWJGL Application" java.lang.RuntimeException: No TweenAccessor was found for the target

I am having a difficult time implementing the Universal Tween Engine in my android, desktop, and html libgdx projects (Note that this is a problem with libgdx version 1.3.1 that uses gradle).
I have followed the instructions on the github wiki by using the fileTree method shown in the link below.
https://github.com/libgdx/libgdx/wiki/Universal-Tween-Engine
I managed to set the build path of the CORE and ANDROID projects to include the two tween engine jars. The classes get imported easily but when runnning the DESKTOP project I get the following error:

Your splashTexture isn't the type of Sprite it is Texture!!!
That is your problem.
Create splashSprite from splashTexture, and call this:
Tween.to(splashSprite, SplashAccessor.ALPHA, 3).target(1)
.start(tweenManager);
Hope it helps!

Gridview with universal image loader images are loading slowly

i'm using universal image loader to populate thumbnails into gridview from assets gallary but images are loading slowly during scrolling up or down so i think because images are being loaded with it's current resolution so how i can change the resolution of the images for example i used to use createScaledBitmap to scale down the bitmap
Here is my code :
public class ImageAdapter extends BaseAdapter {
private Context mContext;
private List<String> mList;
private int mheight;
private int mwidth;
private InputStream is;
private HomePage homePage;
private ImageLoader imageLoader;
public ImageAdapter(Context context, List<String> list, int height, int width) {
mContext = context;
mList = list;
mheight = height;
mwidth = width;
ImageLoader imageLoader = ImageLoader.getInstance();
this.imageLoader = imageLoader;
}
#Override
public int getCount() {
return mList.size();
}
#Override
public Object getItem(int position) {
return mList.get(position).toString();
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) {
imageView = new ImageView(mContext);
} else {
imageView = (ImageView) convertView;
}
File cacheDir = new File(Environment.getExternalStorageDirectory(), "UniversalImageLoader/Cache");
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(mContext)
.threadPoolSize(5)
.memoryCacheExtraOptions(mwidth/3, mwidth/3)
.threadPriority(Thread.MIN_PRIORITY )
.memoryCache(new UsingFreqLimitedMemoryCache(5000000)) // You can pass your own memory cache implementation
.discCache(new UnlimitedDiscCache(cacheDir)) // You can pass your own disc cache implementation
.build();
imageLoader.init(config);
//
//
//display options
DisplayImageOptions options = new DisplayImageOptions.Builder()
.showStubImage(R.drawable.loading)
.showImageForEmptyUri(R.drawable.loading)
.cacheInMemory()
.cacheOnDisc()
.bitmapConfig(Bitmap.Config.RGB_565)
.imageScaleType(ImageScaleType.EXACTLY)
.build();
// // Create configuration for ImageLoader
String imString = mList.get(position);
String imageUria = "assets://"+imString;
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setLayoutParams(new GridView.LayoutParams(mwidth/3, mwidth/3));
imageLoader.displayImage(imageUria, imageView ,options );
return imageView ;
}
}
