Recyclerview с пользовательскими GridlayoutManager андроида

Question

Я работаю на пользовательский макет RecyclerView с GridLayoutManager

, который должен выглядеть следующим образом

adapter.java

@Override 
    public void onBindViewHolder(ProfilePhotosViewHolder ProfilePhotosViewHolder, final int position) { 

     model = list.get(position); 


     if (position == 0) { 
      ProfilePhotosViewHolder.relativeBucket.setVisibility(View.VISIBLE); 
      ProfilePhotosViewHolder.relativeBucket.setDrawingCacheEnabled(true); 
      ProfilePhotosViewHolder.relativeBucket.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), 
        View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED)); 
      ProfilePhotosViewHolder.relativeBucket.layout(0, 0, ProfilePhotosViewHolder.relativeBucket.getMeasuredWidth(), ProfilePhotosViewHolder.relativeBucket.getMeasuredHeight()); 
      ProfilePhotosViewHolder.relativeBucket.buildDrawingCache(true); 
      Bitmap b = Bitmap.createBitmap(ProfilePhotosViewHolder.relativeBucket.getDrawingCache()); 
      ProfilePhotosViewHolder.relativeBucket.setDrawingCacheEnabled(false); 
      ByteArrayOutputStream bytes = new ByteArrayOutputStream(); 
      b.compress(Bitmap.CompressFormat.JPEG, 100, bytes); 
      ProfilePhotosViewHolder.imgProfilePhotos.setImageBitmap(b); 
     } 

     if (position == 2) { 
      ProfilePhotosViewHolder.relativeFollowers.setVisibility(View.VISIBLE); 
      ProfilePhotosViewHolder.relativeFollowers.setDrawingCacheEnabled(true); 
      ProfilePhotosViewHolder.relativeFollowers.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), 
        View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED)); 
      ProfilePhotosViewHolder.relativeFollowers.layout(0, 0, ProfilePhotosViewHolder.relativeFollowers.getMeasuredWidth(), ProfilePhotosViewHolder.relativeFollowers.getMeasuredHeight()); 
      ProfilePhotosViewHolder.relativeFollowers.buildDrawingCache(true); 
      Bitmap b = Bitmap.createBitmap(ProfilePhotosViewHolder.relativeFollowers.getDrawingCache()); 
      ProfilePhotosViewHolder.relativeFollowers.setDrawingCacheEnabled(false); 
      ByteArrayOutputStream bytes = new ByteArrayOutputStream(); 
      b.compress(Bitmap.CompressFormat.JPEG, 100, bytes); 
      ProfilePhotosViewHolder.imgProfilePhotos.setImageBitmap(b); 
     } 
     if (position == 5) { 
      ProfilePhotosViewHolder.relativeFollowing.setVisibility(View.VISIBLE); 
      ProfilePhotosViewHolder.relativeFollowing.setDrawingCacheEnabled(true); 
      ProfilePhotosViewHolder.relativeFollowing.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), 
        View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED)); 
      ProfilePhotosViewHolder.relativeFollowing.layout(0, 0, ProfilePhotosViewHolder.relativeFollowing.getMeasuredWidth(), ProfilePhotosViewHolder.relativeFollowing.getMeasuredHeight()); 
      ProfilePhotosViewHolder.relativeFollowing.buildDrawingCache(true); 
      Bitmap b = Bitmap.createBitmap(ProfilePhotosViewHolder.relativeFollowing.getDrawingCache()); 
      ProfilePhotosViewHolder.relativeFollowing.setDrawingCacheEnabled(false); 
      ByteArrayOutputStream bytes = new ByteArrayOutputStream(); 
      b.compress(Bitmap.CompressFormat.JPEG, 100, bytes); 
      ProfilePhotosViewHolder.imgProfilePhotos.setImageBitmap(b); 
     } 
     if (position == 7) { 
      ProfilePhotosViewHolder.relativePosts.setVisibility(View.VISIBLE); 
      ProfilePhotosViewHolder.relativeFollowing.setDrawingCacheEnabled(true); 
      ProfilePhotosViewHolder.relativeFollowing.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED), 
        View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED)); 
      ProfilePhotosViewHolder.relativeFollowing.layout(0, 0, ProfilePhotosViewHolder.relativeFollowing.getMeasuredWidth(), ProfilePhotosViewHolder.relativeFollowing.getMeasuredHeight()); 
      ProfilePhotosViewHolder.relativeFollowing.buildDrawingCache(true); 
      Bitmap b = Bitmap.createBitmap(ProfilePhotosViewHolder.relativeFollowing.getDrawingCache()); 
      ProfilePhotosViewHolder.relativeFollowing.setDrawingCacheEnabled(false); 
      ByteArrayOutputStream bytes = new ByteArrayOutputStream(); 
      b.compress(Bitmap.CompressFormat.JPEG, 100, bytes); 
      ProfilePhotosViewHolder.imgProfilePhotos.setImageBitmap(b); 
     } 
     ProfilePhotosViewHolder.imgProfilePhotos.setImageResource(model.photos); 

     ProfilePhotosViewHolder.imgProfilePhotos.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       mMethods.showToast(mContext, "" + position); 
      } 
     }); 

    } 

layout.xml

    </RelativeLayout> 

Проблема заключается в том, что пользовательский макете, который преобразуется в Bitmap в соответствии с фиксированным положением правильно

Answer 1

не выровнен Для сохранения вида квадрата зрения Recycler:

к onBind функции ViewHolder Я прошел ширину столбца (он был рассчитан как размер экрана/количество столбцов), а внутри ViewHolder был

itemView.setLayoutParams(new FrameLayout.LayoutParams(width, width)); 

где itemView - вид ViewHolder, а ширина - ширина столбца. Конечно, для этого нужен FrameLayout.

надеюсь, что это поможет.

веселит

EDIT: Вы можете использовать

itemView.setLayoutParams(new RelativeLayout.LayoutParams(width, width)); 

если родитель является относительной раскладкой
