is it possible to add a new binder dynamically after already initializing EnumListBindAdapter and using addAllBinder in the constructor? I have a different row type that i want to add if a certain condition is met, and removed if not.

I get this error when using clear() in Sample2Binder

java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder{4266fe38 position=2 id=-1, oldPos=2, pLpos:-1 scrap [attachedScrap] tmpDetached no parent}

//TYPE1
public void bindViewHolder(ViewHolder holder, int position) {
            Log.w("bindViewHolder",position+" "+getPosition(this,position));
}

0 1 1 1 2 2 3 3 should be: 0 1 1 2 2 3 3 4

data example: TYPE0 TYPE1 TYPE1 TYPE1

in getPosition

                --binderPosition;
                if(binderPosition <= 0) {

when positionOfBinder==0, after1 loop, -1<=0 so return 1 (correct) when positionOfBinder==1, after1 loop, 0<=0 so return 1 (wrong, it should be 2)

i think binderPosition should not <0, so i fix it with

                if(binderPosition-- <= 0) {

when positionOfBinder==0, after1 loop, 0<=0 so return 1 (correct) when positionOfBinder==1, first loop 1<=0 is false , second loop, 0<=0 so return 2 (correct)

Does this library support two dynamic lists? For example if I have two different binders that each have a dynamic list, would I need to do anything differently to get it to work?

Currently I'm getting indexing issues when using ListBindAdapter. What's the best way to do this? thanks in advance

Hey,

I am using setBinder(0, newBinder) to replace the first item on my adapter (ListBindAdapter), and then called notifyBinderItemRangeChanged(newBinder, 0, 1). It is unable to replace the first DataBinder.

It crashed at com.yqritc.recyclerviewmultipleviewtypesadapter.DataBindAdapter.onBindViewHolder(DataBindAdapter.java:21)

Hi,

I'm implementing a clever approach to notifyBinderDataSetChanged - so that calling this will automatically figure out if it should add/remove or update the items.

Would you be interested in a PR once I get this working or you see this as besides the scope of this lib ?

User case here would be that users can simply add/remove/update items in a binder and simply call notifyBinderDataSetChanged and not having to worry about what actions they took.

Every now and then I end up getting a class cast exception such as:

java.lang.ClassCastException: com.vivino.android.marketsection.binders.ComputationalTopListsBinder$ViewHolder cannot be cast to com.vivino.android.marketsection.binders.HighlightedOfferBinder$ViewHolder

Seems its picking the wrong binder at the wrong time and then things go south...

This happens only when I use my custom adapter with support for removeBinder - So not really your wrong doing..

Thank you very much for such an amazing library! I have made tiny modification here to make the library performance better just a tiny bit..

Done

I have modified for loops inside EnumMapBindAdapter and ListBindAdapter to calculate initial list size only once. I have decided to make this modification after seeing this youtube video: https://www.youtube.com/watch?v=b6zKBZcg5fk&feature=youtu.be&t=1537

What does getITemViewType do in EnumMapBindAdapter exactly? and what if I have one arraylist of different object types and not separate lists, how can I change view types based on object type?, if I use separate binders then i have to have separate lists, so I tried using one binder and override getItemViewType in it, but turned out I can't since it extends ViewHolder.

I am using EnumMapBindAdapter to display userposts list .Here I am using 4 binders ,each binder has a list of size 3 . I have problem with getEnumFromPosition() ,According to my assumptions number of executions of getEnumFromPosition() method should be equal to number of binders (4) . But it is not happening .I have total 4 binders and I assume getEnumFromPosition() method should execute 4 times only (0,1,2,3) ,but executions are being excedeed . My assumption may be wrong ,If I am wrong then how can I manage 4 binders inside getEnumFromPosition() for different positions . If I put else section then it will return a single view when position exceeds .

Here is the code of SampleEnumMapAdapter.java

public class SampleEnumMapAdapter extends EnumMapBindAdapter<SampleEnumMapAdapter.SampleViewType> {

enum SampleViewType{
    TEXT,IMAGE_AND_TEXT, AUDIO_AND_TEXT, VIDEO_AND_TEXT
}

public SampleEnumMapAdapter(){
    putBinder(SampleViewType.TEXT, new TextBinder(this));
    putBinder(SampleViewType.IMAGE_AND_TEXT, new ImageAndTextBinder(this));
    putBinder(SampleViewType.AUDIO_AND_TEXT, new AudioAndTextBinder(this));
    putBinder(SampleViewType.VIDEO_AND_TEXT, new VideoAndTextBinder(this));
}

public void setData(List<TextData> dataSetText ,List<ImageAndTextData> dataSetTextAndImage ,List<AudioAndTextData> dataSetTextAndAudio ,List<VideoAndTextData> dataSetTextAndVideo ) {
    ((TextBinder) getDataBinder(SampleViewType.TEXT)).addAll(dataSetText);
    ((ImageAndTextBinder) getDataBinder(SampleViewType.IMAGE_AND_TEXT)).addAll(dataSetTextAndImage);
    ((AudioAndTextBinder) getDataBinder(SampleViewType.AUDIO_AND_TEXT)).addAll(dataSetTextAndAudio);
    ((VideoAndTextBinder) getDataBinder(SampleViewType.VIDEO_AND_TEXT)).addAll(dataSetTextAndVideo);
}

@Override
public SampleViewType getEnumFromPosition(int position){
    if (position == 0) {
        return SampleViewType.TEXT;
    } else if (position == 1) {
        return SampleViewType.IMAGE_AND_TEXT;
    } else if(position == 2){
        return SampleViewType.AUDIO_AND_TEXT;
    }else if(position == 3){
        return SampleViewType.VIDEO_AND_TEXT;
    }
    return null;
}

@Override
public SampleViewType getEnumFromOrdinal(int ordinal) {
    return SampleViewType.values()[ordinal];
}

}

thank you for your great multipleViewTypesAdapter.

but when i used it wanting to show a StaggeredGrid UI, i found something undesirably.

it can not show staggerGrid but the different children has the same height .

So how to implement StaggeredGrid with multipleViewTypesAdapter,thanks a lot.

as my code: MainActivity.java

onCreate(Bundle savedInstanceState) { ... RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview_main); SampleEnumListAdapter adapter = new SampleEnumListAdapter(); recyclerView.setAdapter(adapter); // recyclerView.setLayoutManager(new LinearLayoutManager(this)); // 瀑布流 recyclerView.setLayoutManager(new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL)); // 自定义分割线 // SpacesItemDecoration decoration = new SpacesItemDecoration(this, // SpacesItemDecoration.VERTICAL_LIST); // recyclerView.addItemDecoration(decoration); // -----------// List sampleData = getSampleData(); adapter.setSample2Data(sampleData); ...

}

and the different binder

Sample1Binder.java

@Override public void bindViewHolder(ViewHolder holder, int position) { ViewGroup.LayoutParams params = holder.itemView.getLayoutParams();// 得到item的LayoutParams布局参数 params.height = 50;// 把随机的高度赋予item布局 holder.itemView.setLayoutParams(params);// 把params设置给item布局

    Picasso.with(holder.mImageView.getContext())
    .load(R.drawable.bird)
    .into(holder.mImageView);
}

Simple2Binder.java

@Override public void bindViewHolder(ViewHolder holder, int position) { ViewGroup.LayoutParams params = holder.itemView.getLayoutParams();// 得到item的LayoutParams布局参数 params.height = 100;// 把随机的高度赋予item布局 holder.itemView.setLayoutParams(params);// 把params设置给item布局

    SampleData data = mDataSet.get(position);
    holder.mTitleText.setText(data.mTitle);
    holder.mContent.setText(data.mContent);
    holder.mImageView.setImageResource(R.drawable.animal1);

}

Sample3Binder.java

public void bindViewHolder(ViewHolder holder, int position) { ViewGroup.LayoutParams params = holder.itemView.getLayoutParams();// 得到item的LayoutParams布局参数 params.height = 150;// 把随机的高度赋予item布局 holder.itemView.setLayoutParams(params);// 把params设置给item布局

    holder.mImageView.setImageResource(R.drawable.animal3);

}
