Hi ,

I am trying to wrap this project https://github.com/Rogero0o/GifLoadingView but getting the following error when compiling .

Can any one help please ?
Here is my source code : http://www.fileconvoy.com/dfl.php?id=g1a1bd24ea2552faf99982236077f2a17e833743a8

Do you intend to expose this class? If not add: pl.droidsonroids to the ignore field.

I already added it to ignore field.

I deleted @see form source code and it compiles OK but I tried to rename class but got this error

B4X:

smmgifloadingview.java:30: error: type argument GifLoadingView is not within bounds of type-variable T
public class smmgifloadingview extends ViewWrapper <GifLoadingView>{
                                                    ^
  where T is a type-variable:
    T extends View declared in class ViewWrapper

Error.

GifLoadingView is probably not a subclass of View.

I think it uses fragmentManager , I followed your example here https://www.b4x.com/android/forum/threads/how-to-work-with-dialogfragments.52117/#post-326325
Now it compiles Ok but I got some Resources errors I will try to correct them.
Thanks a lot .

Hello again
I don't know how to wrap this .
What is supposed to be passed to setImageResource method ?

B4X:

mGifLoadingView.setImageResource(R.drawable.image);

I suggest to use it this way (that´s what i do in my wraps)

B4X:

  public void setImageResource(final BA ba, String imageResource) {
         int resourceId=BA.applicationContext.getResources().getIdentifier(imageResource, "drawable", BA.packageName);
      this.getObject().setImageResource(resourceId);
  }

Place the drawable in your res folder in the folder drawable. maybe test.png

B4X:

obj.setImageResource("test")

B4X:

obj.setImageResource("test")

I am not using setObject and tried

B4X:

        int resourceId=BA.applicationContext.getResources().getIdentifier(imageResource, "drawable", BA.packageName);
        re.setImageResource(resourceId);

re is my GifLoadingFragment

but I get

B4X:

android.content.res.Resources$NotFoundException: Resource ID #0x0

DonManfred · May 3, 2016

how did you call the method? Is the drawable avalable in the drawable folder in res folder?
Again: i suggest to use it the way i posted above.

You need to get the "resourceID" of the drawable you are requesting. If you dont have this id you are lost in b4a. Give the drawable name as string and get the id from the code i posted.

I followed a source code that Erel posted about Fragment because I believe this library uses it .

which code exactly did you follow?

You need to get the "resourceID" of the drawable you are requesting. If you dont have this id you are lost in b4a. Give the drawable name as string and get the id from the code i posted.

resources are like "num0.gif" but it seems that the library requests an int ID .
by some logging from library I can see I am having a real ID because otherwise I will get a 0

This one

DonManfred · May 3, 2016

i guess a gif should not be searched by the method i posted (and you are using in yxour code). It will get the id of a DRAWABLE.
Maybe you need to get raw-id?

but you are not using a fragmentmanager in your code!?

DonManfred · May 3, 2016

Erel wrote that it is not easy too. You need to learn how the fragmentmanager is included in the mapview-source.
Then you need to build a fragmentmanager for your lib.

Sadly I did not get it to run till now... :-/
I always take the curve if i need to wrap a lib which is using fragments.

DonManfred · May 3, 2016

I have around 20 libs which are not working as of this :-/ (maybe more)

You are right I commented this line

B4X:

re = (GifLoadingFragment) ba.activity.getFragmentManager().findFragmentById(Parent.getId());

which I thought is what I need and forgot
