Here i am showing all the images in "ALL" section. how to show the remain images of every catgory. I added my screenshot which will show the images . "ALL" means every category type image will showing in this section.
Here i can showing all images in "ALL" Section, now how to move to automatically show the images based on category.

How to call Android layout in Unity?

I am finding the solution of my problem but not satisfied from all of them.
I create an android library which shows a ad view layout witch is and know I want to call this layout in unity but can't find any solution please anyone help me how can I call my layout in unity?
public class RedeemLayout extends LinearLayout implements View.OnClickListener,HttpCallBacks {

}
}
private void DownloadAdAccordingToLocation() {
try {

} catch (IOException e) {
e.printStackTrace();
}
}
public void adButtonClicked(View v) {
// FullScreenAdDialog db = new FullScreenAdDialog(this, ad, updateAdClick);
// db.show();
// Intent x = new Intent(xcontext, AdActivity.class);
// x.putExtra("image_link", ad.getImage_link());

} else {
ad = AdInfo.fromJson(response);
if (ad.isSuccess()) {
Picasso.Builder builder = new Picasso.Builder(context);
builder.listener(new Picasso.Listener() {
#Override
public void onImageLoadFailed(Picasso picasso, Uri uri, Exception exception) {
redeemLayout.removeAllViews();
redeemLayout.setVisibility(View.GONE);
}
});
Picasso pic = builder.build();
pic.load(ad.getImage_url()).into(bmImage);
// Picasso.with(context)
// .load(ad.getImage_url())
// .error(R.drawable.imagecross)
// .into(bmImage);
} else {
Log.e("Error", response.getString("parseError"));
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
and call my library in android app like this.
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RelativeLayout layout= (RelativeLayout)findViewById(R.id.test);
RedeemLayout redeemLayout= new RedeemLayout(this, this);
redeemLayout.setGravity(Gravity.CENTER);
layout.addView(redeemLayout);
}
}

It's more unity3d question. You cannot call your layout directly, you can only send message to android code. Read Unity3d script documentation (or google for code) of AndroidJavaClass and AndroidJavaObject.
From Android perspective I think that you should implement some kind of static method that you can call from unity and it should broadcast or send event in event bus that will be handled by your advertisement engine.
Unity part of code should be similar to this:
AndroidJavaClass javaClass = new AndroidJavaClass("com.mypackage.MyClassWithMyStaticMethod");
javaClass.getStatic<AndroidJavaObject>("MyStaticMethod", 42);
Android MyClassWithMyStaticMethod class should implement:
public static void MyStaticMethid(int param) {...}
Check this doc: AndroidJavaClass

Android async task frame animation

To begin with I have tried a lot of ways to make a smooth animation in Android and probably my best option was to use AnimationDrawable. Everything was perfect until I got out of memory exception on older devices. The reason for that obviously is the number of frames, in my case 75. That is how I got to the point of using AsyncTask and Thread.sleep() to animate the frames. To avoid animation lag I used a Stack in which I preload the first 10 frames and then just pop the used one and push a new one until there are no more frames. Everything worked better than I expected, but the only problem is that at the end of the animation the last frame disappears and I am hitting my head whole day to understand why is that happening with no success obviously. Below is the code from the Activity in which I call the animation and the file where the animation code is.
SplashActivity.java
private void startAnimation() {
gifImageView = (LogoAnimImageView) findViewById(R.id.gifImageView);
gifImageView.setSplashActivityContext(this);
gifImageView.setBackgroundResource(R.drawable.logo_frame_0);
gifImageView.setAnimImageViewListener(new LogoAnimImageView.LogoAnimImageViewInterface() {
#Override
public void animationEnd() {
mAnimationFinished = true;
LoadNextActivity();
}
});
gifImageView.startLogoAnimation();
}

}
else {
LogoAnimImageView.this.setBackgroundDrawable(drawable);
}
}
});
mListener.animationEnd();
super.onPostExecute(s);
}
}
}

...but the only problem is that at the end of the animation the last
frame disappears and I am hitting my head whole day to understand why
is that happening with no success obviously.
The problem may lie in your AsyncTask's onPostExecute(String):
#Override
protected void onPostExecute(String s) {
mSplashActivity.runOnUiThread(new Runnable() {
#Override
public void run() {
Drawable drawable = getDrawable(R.drawable.logo_frame_74);
if(android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
LogoAnimImageView.this.setBackground(drawable);
} else {
LogoAnimImageView.this.setBackgroundDrawable(drawable);
}
}
});
mListener.animationEnd();
super.onPostExecute(s);
}
onPostExecute(String) will always be called on the UI thread. So, mSplashActivity.runOnUiThread(....) is redundant.
By using runOnUiThread(Runnable), you are posting to the UI thread's event queue. So, the runnable is executed when its turn comes up. However, the code after the mSplashActivity.runOnUiThread(....) call may get executed before the runnable. So, mListener.animationEnd() may be getting called before your LogoAnimImageView has a chance to display R.drawable.logo_frame_74.
But, this should not happen in your case. If runOnUiThread(Runnable) is called from the UI thread (which, it is), the Runnable is not posted to the event queue, and executed immediately instead.
I suspect that the real issue here is that there isn't any delay between the last frame of your animation (R.drawable.logo_frame_74), and launch of next activity. Perhaps you could comment out the call to mListener.animationEnd(), to check whether the animation ends at the last or second-last frame.
Although this is an interesting approach, and one I haven't seen before, I have to say that you are meddling with more threads than you need to. If you're trying to load Drawables as and when they are needed, there is a simpler way:
public class LogoAnimImageView extends ImageView {
....
....
// flag to indicate whether `mNextFrameDrawable` should continue loading the next frame
private boolean mStopAnimating;
// loads the next frame, and calls back to activity when done
private Runnable mNextFrameRunnable = new Runnable() {
#Override
public void run() {
if (!mStopAnimating) {
if (isFinishedAnimating() && mListener != null) {
mListener.animationEnd();
} else { // Load next frame
setViewBg(getNextFrameDrawable());
// Will load the next frame in 40 ms
postDelayed(this, 40L);
}
}
}
};
// This method can be set `public static` and placed in a separate `Utils` class
private void setViewBg(Drawable d) {
if(android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
setBackground(drawable);
} else {
setBackgroundDrawable(drawable);
}
}
private Boolean isFinishedAnimating() {
return mFrameIndex >= mResources.length;
}
// returns the next frame's drawable and increments the `mFrameIndex` pointer
private Drawable getNextFrameDrawable() {
return getDrawable(mResources[mFrameIndex++]);
}
// start animating
public void startLogoAnimation() {
mFrameIndex = 0;
mStopAnimating = false;
post(mNextFrameRunnable);
}
// stop animating
public void stopLogoAnimation() {
mStopAnimating = true;
removeCallbacks(mNextFrameRunnable);
}
....
....
}
AsyncTask is neither needed, nor designed to handle such scenarios.

Android custom view drawing twice

In my activity A, this view called twice, but in my activity B, there is no problem.
Activity A is very simple layout with a few linearLayout. I'm about to go crazy, what can be the problem?
Here is I have my AdBannerView:
public class AdBannerView extends LinearLayout {
public ImageView adIcon, adInstall;
public TextView_ adTitle, adDesc;
public ProgressBar adProgress;
RelativeLayout adWrapperLay;
private boolean impSent, adLoaded = false;
public AdBannerView(Context context) {
super(context);
}
public AdBannerView(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
public AdBannerView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
private void init(Context context) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View wrapper = inflater.inflate(R.layout.view_ad_banner, this, true);
adIcon = (ImageView) wrapper.findViewById(R.id.adIcon);
adInstall = (ImageView) wrapper.findViewById(R.id.adInstall);
adTitle = (TextView_) wrapper.findViewById(R.id.adTitle);
adDesc = (TextView_) wrapper.findViewById(R.id.adDesc);
adProgress = (ProgressBar) wrapper.findViewById(R.id.adProgress);
adWrapperLay = (RelativeLayout) wrapper.findViewById(R.id.adWrapperLay);
Log.d("AdBannerView", "before loadAd()");
if(NativeAdManager.getInstance().isAdEnabled)
loadAd();
}
public void loadAd(){
if(adLoaded)
return;
adLoaded = true;
Log.d("AdBannerView", "loadAd() request");
NativeAdManager.getInstance().getAd(getContext(), new NativeAdManager.AdListener() {
#Override
public void adLoaded(final NativeAdResponse.Ads[] ads) {
/* load img */
Picasso
.with(getContext())
.load(ads[0].adIc)
.into(adIcon);
/* load title */
adTitle.setText(""+ads[0].adTit);
adDesc.setText(""+ads[0].adDesc);
/* click listener */
adInstall.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
App app = (App) getContext().getApplicationContext();
app.getUiController().loadUrlWithoutAdBlocker(ads[0].adClk);
}
});
/* show this layout */
showAd(ads[0].adBeacons);
Log.d("AdBannerView", "loaded with size = " + ads.length);
}
});
}
private void showAd(final NativeAdResponse.adBeacons[] adBeacons) {
adProgress.setVisibility(GONE);
adIcon.setVisibility(VISIBLE);
}
}
I'm including to layout like this:
<.... AdBannerView match_parent etc />

Here's your bug :) Hopefully
You have in your base a call to setContentView and then in your deriving class you have call to super create (which calls the setContentView [which creates the adElement]) but after that you call again setContentView(getLayoutResourceId()); (this time from your derived class which overrides the layout but even if it didn't it's calling actually the same content I imagine so that's why it looks normal :)
So the fix should be easy - remove the setContentView(getLayoutResourceId()) from your activity A because it's already called from the base activity

Android kankan-wheel modification

I am making a slot machine app and using kankan's wheel for the same. I want to modify the library such that when the rotation stops the item it will point shoud be the one that I set . I have done this but there is a glitch that shows that we have changed the actual image to the one that we want . How to achieve this?
Update:
I have researched a lot on this and if I am right , android scroll is based on duration and distance not items . From kankan's wheel library I can get current item .Now , I am trying to stop the animation as well as scroll , as soon as a certain duration has been reached and the item is the one that I want (through index) . But this is not working .Please help!!

This is the code. Through this code, when slot stops I want it to scroll some more untill it reaches the image position that I receaved from server. I can do this .But this is providing a lil glitch . Is there any way to stop scrolling when the image is reached as soon as certain duration is reached.
P.S. If you need anymore detail I can provide you.
P.P.S. Screenshots wont give you any detailed insight about the issue.

After days of searching I finally did it.All I had to do was set interpolater as LinearInterpolater and While setting setCurrentItem set animation as true.
