Bevor ich dies als ein Duplikat markiert habe, habe ich alle Lösungen ausprobiert, aber nichts hat funktioniert. Bitte gehen Sie die Frage durch und helfen Sie mir.ViewPager in einem Recyclerview
Ich habe eine Recycler-Ansicht, die mehrere viewPagers haben wird und beide werden einzeln scrollen. Ich kann das anscheinend nicht umsetzen. Mein Code ist wie folgt
RecyclerView Adapter
public class Adapter extends RecyclerView.Adapter<Adapter.holder> {
private final LayoutInflater mLayoutInflater;
private final Context context;
private final RecyclerView r;
private OnLoadMoreListener onLoadMoreListener;
ArrayList<ceo> mArray = new ArrayList<>();
private int heightPixels;
private int widthPixels;
MainActivity contextActivity;
public holder mh;
public Adapter(Context mContext, final RecyclerView r,MainActivity conts) {
contextActivity=conts;
this.r=r;
context = mContext;
mLayoutInflater = LayoutInflater.from(mContext);
r.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
if (!r.canScrollVertically(1)) {
onLoadMoreListener.onLoadMore();
}
}
});
}
public void setmArray(ArrayList<ceo> mArray) {
this.mArray = mArray;
Log.e("This->", mArray.toString());
notifyItemRangeChanged(0, mArray.size());
}
@Override
public holder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = mLayoutInflater.inflate(R.layout.recycler_custom_photo,viewGroup, false);
mh = new Adapter.holder(v);
return mh;
}
public void setOnLoadMoreListener(OnLoadMoreListener onLoadMoreListener) {
this.onLoadMoreListener = onLoadMoreListener;
}
@Override
public void onBindViewHolder(holder holder, int i) {
ViewPagerAdapter mp = new ViewPagerAdapter(context,mArray);
holder.vp.setAdapter(mp);
}
@Override
public int getItemCount() {
return mArray.size();
}
class holder extends RecyclerView.ViewHolder {
ViewPager vp;
public holder(View itemView) {
super(itemView);
vp=(ViewPager)itemView.findViewById(R.id.pager);
}
}
}
Ansicht Pager Adapter
public class ViewPagerAdapter extends PagerAdapter {
ArrayList<ceo> alias=null;
private boolean tk=true;
Context mcov;
public ViewPager(Context context,ArrayList<ceo> checkAlias) {
mcov=context;
this.alias=checkAlias;
}
@Override
public int getCount() {
Log.e("Sze",alias.size()+"");
return alias.size();
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
public void setNestedIndic(boolean token)
{
tk=token;
}
public Bitmap decodeFile(File f) {
try {
//Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(f), null, o);
//The new size we want to scale to
final int REQUIRED_SIZE = 290;
//Find the correct scale value. It should be the power of 2.
int scale = 1;
while (o.outWidth/scale/2 >= REQUIRED_SIZE && o.outHeight/scale/2 >= REQUIRED_SIZE)
scale *= 2;
//Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
} catch (FileNotFoundException e) {
}
return null;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
LayoutInflater mlAy = (LayoutInflater) mcov
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View m=mlAy.inflate(R.layout.custom_photo, container, false);
ImageView mimg=(ImageView)m.findViewById(R.id.mainImageFeed);
TextView tc=(TextView)m.findViewById(R.id.texr);
String path=alias.get(position).getPath();
Log.e("Pos",""+position);
tc.setText(position+" ");
container.addView(m);
return m;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
// Remove viewpager_item.xml from ViewPager
((android.support.v4.view.ViewPager) container).removeView((RelativeLayout) object);
}
}
recycler_custom_photo.xml
<?xml version="1.0" encoding="utf-8"?>

Welche Veränderungen muss ich diese Arbeit zu machen machen? Danke für die Antwort!
