Question

我在RecycleView中有一个带有复杂视图项的ViewPager。 RecycleView将被放入片段中。当我将片段加载到Activity中时。我看到片段的onCreateView方法被调用。但我总是得到RuntimeException anvas：尝试绘制太大（207360000bytes）的位图作为日志：

这是我的代码： 1.我的ViewPager适配器：

    public class HighLightAdapter extends PagerAdapter {

    private final String TAG = "VT_HighLightAdapter";

    private List<HighLightModelReponse> dataModels;

    public HighLightAdapter(List<HighLightModelReponse> dataModels){
        Log.d(TAG,"HighLightAdapter contructor");
        this.dataModels = dataModels;
    }

    @Override
    public int getCount() {
        return dataModels.size();
    }


    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        Log.d(TAG,"instantiateItem");
        View itemView = LayoutInflater.from(container.getContext()).inflate(R.layout.hightlights_items,container,false);
        RelativeLayout base_item = (RelativeLayout) itemView.findViewById(R.id.base_item);
        //header
        TextView header_catalog = (TextView) itemView.findViewById(R.id.tv_header_catalog);
        TextView header_details = (TextView) itemView.findViewById(R.id.tv_header_detail);
        //content image
        ImageView image_preview = (ImageView) base_item.findViewById(R.id.img_preview);
        ImageView image_delete = (ImageView) base_item.findViewById(R.id.img_delete_favorate);
        image_delete.setVisibility(View.INVISIBLE);
        //footer
        TextView footer_title = (TextView) base_item.findViewById(R.id.tv_footer_title);
        TextView footer_slogan = (TextView) base_item.findViewById(R.id.tv_footer_slogan);
        TextView footer_info = (TextView) base_item.findViewById(R.id.tv_footer_info);
        //rating
        RatingBar ratingBar = (RatingBar) base_item.findViewById(R.id.footer_rating);
        TextView numberRate = (TextView) base_item.findViewById(R.id.tv_number_rate);

        TextView numberComments = (TextView) base_item.findViewById(R.id.tv_number_comment);

        HighLightModelReponse highLightModelReponse = dataModels.get(position);
        String image_url = highLightModelReponse.getImage_url();
        if(image_url != null && !image_url.isEmpty()){
            Picasso.with(container.getContext())
                    .load(image_url)
                    .resize(image_preview.getWidth(),image_preview.getHeight())
                    .placeholder(R.drawable.ic_contact)
                    .error(R.drawable.ic_contact)
                    .into(image_preview, new Callback() {
                        @Override
                        public void onSuccess() {
                            Log.d(TAG,"Picasso onLoad success");
                        }

                        @Override
                        public void onError() {
                            Log.d(TAG,"Picasso onLoad Error");
                        }
                    });
           /* UiUtils.loadImageFromLink(container.getContext(),image_url,image_preview,image_preview.getWidth(),image_preview.getHeight());
            image_preview.setScaleType(ImageView.ScaleType.CENTER_CROP);*/
        }
        header_catalog.setText(highLightModelReponse.getCatalog());
        header_details.setText("Xem chi tiết");

        footer_title.setText(highLightModelReponse.getTitle());
        footer_slogan.setText(highLightModelReponse.getSlogan());
        footer_info.setText(highLightModelReponse.getMore_infor());

        ratingBar.setRating(highLightModelReponse.getAverRating());
        numberRate.setText(String.valueOf(highLightModelReponse.getNumberRating()));
        numberComments.setText(String.valueOf(highLightModelReponse.getNumberComments()));
        container.addView(itemView);
        return itemView;
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        ((ViewPager)container).removeView((View)object);
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }
    }

这是我的RecycleView Adaper：

public class HighLightRecycleAdapter extends RecyclerView.Adapter {

private final String TAG = "VT_HighLightRecycleAdapter";
private List<List<HighLightModelReponse>> highLightData;

private Context mContext;


public HighLightRecycleAdapter(Context context,List<List<HighLightModelReponse>> datas){
    Log.d(TAG,"HighLightRecycleAdapter contructor");
    this.mContext = context;
    highLightData = datas;
}



@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.pager_item,parent,false);
    return new HighLightViewHolder(itemView);
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    List<HighLightModelReponse> pagerDatas = highLightData.get(position);
    initializeViews(pagerDatas,holder,position);
}

@Override
public int getItemCount() {
    return highLightData.size();
}

private void initializeViews(List<HighLightModelReponse> dataModel, final RecyclerView.ViewHolder holder, int position){

    Log.d(TAG,"initializeViews");
    HighLightAdapter adapter = new HighLightAdapter(dataModel);
    ((HighLightViewHolder)holder).viewPager.setAdapter(adapter);
    ((HighLightViewHolder)holder).viewPager.setClipToPadding(false);
    ((HighLightViewHolder)holder).viewPager.setPadding(40, 0, 40, 0);
    ((HighLightViewHolder)holder).indicator.setViewPager(((HighLightViewHolder)holder).viewPager);
    final float density = mContext.getResources().getDisplayMetrics().density;
    ((HighLightViewHolder)holder).indicator.setRadius(5 * density);
}

public static class HighLightViewHolder extends RecyclerView.ViewHolder{

    private final String TAG = "HighLightViewHolder";

    @BindView(R.id.view_pager)
    ViewPager viewPager;
    @BindView(R.id.indicator)
    CirclePageIndicator indicator;

    public HighLightViewHolder(View itemView) {
        super(itemView);
        ButterKnife.bind(this,itemView);
        Log.d(TAG, "HighLightViewHolder contructor");
    }
}
}

My Fragment

public class HighLightFragment extends BaseFragment<HighLightPresenter> implements HighLightContract.View {

private final String TAG = "VT_HighLightFragment";

private List<List<HighLightModelReponse>> mHighLightData;

@BindView(R.id.highlight_recycleview)
RecyclerView mHighlightRecycleview;


@Override
protected int getLayoutId() {
    return R.layout.hightlights_activity;
}

@Override
protected void initEventAndData() {
    Log.d(TAG,"initEventAndData");
    initDataHighLightModelTest();

    LinearLayoutManager mLayoutManager = new LinearLayoutManager(mContext);

    HighLightRecycleAdapter recycleAdapter = new HighLightRecycleAdapter(mContext,mHighLightData);
    mHighlightRecycleview.setAdapter(recycleAdapter);
    DividerItemDecoration mDividerItemDecoration = new DividerItemDecoration(mHighlightRecycleview.getContext(), mLayoutManager.getOrientation());
    mHighlightRecycleview.addItemDecoration(mDividerItemDecoration);
}

@Override
protected void initInject() {
    getFragmentComponent().inject(this);
}


private void initDataHighLightModelTest(){
    String catalog1 = "catalog1";
    String catalog2 = "catalog2";
    String catalog3 = "catalog3";
    String catalog4 = "catalog4";

    String title1 = "title1";
    String slogan1 = "slogan1";
    String detail1 = "detail1";
    float aver_rating1 = 4.5f;
    int rating_number1 = 7;
    int comment_number1 = 16;
    String image_cover1 = "https://khachsan.dulichvietnam.com.vn/uploads/image/tin-tuc-khach-san/khach-san-grand-plaza-ha-noi4.JPG";

    String title2 = "title2";
    String slogan2 = "slogan2";
    String detail2 = "";
    float aver_rating2 = 4.5f;
    int rating_number2 = 7;
    int comment_number2 = 16;
    String image_cover2 = "https://kenh14cdn.com/2016/3-1476470249125.jpg";

    String title3 = "title3";
    String slogan3 = "slogan3";
    String detail3 = "";
    float aver_rating3 = 4.5f;
    int rating_number3 = 7;
    int comment_number3 = 16;
    String image_cover3 = "http://vietnamtourism.gov.vn/images/2014/ManchinSaPa.jpg";


    HighLightModelReponse h1 = new HighLightModelReponse(catalog1,title1,slogan1,detail1,image_cover1,comment_number1,rating_number1,aver_rating1);
    /*HighLightModelReponse h2 = new HighLightModelReponse(catalog2,title2,slogan2,detail2,image_cover2,comment_number2,rating_number2,aver_rating2);
    HighLightModelReponse h3 = new HighLightModelReponse(catalog3,title3,slogan3,detail3,image_cover3,comment_number3,rating_number3,aver_rating3);*/

    List<HighLightModelReponse> pagerItem1 = Arrays.asList(new HighLightModelReponse[]{h1});
    /*List<HighLightModelReponse> pagerItem2 = Arrays.asList(new HighLightModelReponse[]{h1,h2,h3});
    List<HighLightModelReponse> pagerItem3 = Arrays.asList(new HighLightModelReponse[]{h1,h2,h3});*/
    mHighLightData = new ArrayList<>();
    mHighLightData.add(pagerItem1);
   /* mHighLightData.add(pagerItem2);
    mHighLightData.add(pagerItem3);*/
}
}

    mHighLightFragment = new HighLightFragment();
    FragmentManager fm = getSupportFragmentManager();
    FragmentTransaction ft = fm.beginTransaction();

有人可以帮助我！非常感谢你的帮助

P / s：我无法发布我的布局和Fragment和Activity文件的一些基类，因为它使这个帖子太大（超过30000个字符）。如果您需要任何课程或布局，请免费告诉我。
