Question

我有一个活动和两个片段，** Fragment1 和 Fragment2 。 Fragment1包含 ViewPager ，每页都有一个GridView。我想在点击 GridView 项目时将 Fragment1 替换为 Fragment2 ，但会出现以下错误。

                java.lang.IllegalArgumentException: No view found for id 0x7f0d0078 (atrtrendy.nxg.com.atrtrendy:id/container_main) for fragment Fragment_ViewProduct{425b2ec0 #2 id=0x7f0d0078}

我正在做的事情如下：

private class ProductGridAdapter extends BaseAdapter
{
    Context context;
    ArrayList<Product> productArrayList;
    String url = "http://ecom.nxglabs.in/uploads/productImages/";
    public ProductGridAdapter(FragmentActivity activity, ArrayList<Product> productArrayList) {
        this.context = activity;
        this.productArrayList = productArrayList;
    }

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

    @Override
    public Object getItem(int position) {
        return productArrayList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        String strView = preferences.getString("View","Grid");
        if(strView.equals("Layout"))
        {
            convertView = inflater.inflate(R.layout.product_view_layout_item, null);
        }else {
            convertView = inflater.inflate(R.layout.product_view_item, null);
        }

        ImageView productImg = (ImageView) convertView.findViewById(R.id.productImg);
        TextView productTitle = (TextView) convertView.findViewById(R.id.productTitle);
        TextView productBrand = (TextView) convertView.findViewById(R.id.productBrand);

        Product product = productArrayList.get(position);

        productTitle.setText(product.getProductName());
        productBrand.setText(product.getBrandName());
        Glide.with(getActivity()).load(url + product.getProductImage()).into(productImg);

        productImg.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Fragment_ViewProduct viewProduct = new Fragment_ViewProduct();
                Bundle bundle = new Bundle();
                bundle.putParcelableArrayList("ProductList", productArrayList);
                bundle.putInt("Position", position);
                viewProduct.setArguments(bundle);
                getFragmentManager().beginTransaction().replace(R.id.container_main, viewProduct).commit();
            }
        });
        return convertView;
    }
}

替换时应使用用于添加fragment，相同fragment manager的管理员。您要在fragment中添加Activity并在Adapter中替换。这可能是个问题。

希望这有帮助。

从ViewPager内容移动到新的片段
