生成RecyclerView和AbsListView適配器：AnnotatedAdapter

AnnotatedAdapter是一個只需編寫少量代碼的Android注釋處理器，可生成RecyclerView和AbsListView適配器。

Check out the sample folder, but basically you have to create an adapter class like this and annotate the view types with @ViewType and provide some more information in its annotation:

public class SampleAdapter extends SupportAnnotatedAdapter
                            implements SampleAdapterBinder {

  /**
   * Specify a view type by annotating a public final int with @ViewType.
   * Like for any other adapter the view types must be start with an integer = 0
   */
  @ViewType(
      layout = R.layout.row_medium,   // The layout that will be inflated for this view type
      fields = {                      // The fields of the view holder
        @Field(
            id = R.id.textView,       // The id of this view
            name = "text",            // The name of this field in the generated ViewHolder
            type = TextView.class)    // The type (class) of view in the generated view holder
            }
        }
   )
  public final int mediumRow = 0;     // The annotated ViewType constant


   @ViewType(
        layout = R.layout.row_with_pic,
        fields = {
            @Field(id = R.id.textView, name = "text", type = TextView.class),
            @Field(id = R.id.imageView, name = "image", type = ImageView.class)
        }
    )
  public final int rowWithPic = 1;

  List<String> items;

  public SampleAdapter(Context context, List<String> items) {
    super(context);
    this.items = items;
  }

  /**
   * Get the number of items like in any other adapter
   */
  @Override public int getItemCount() {
    return items == null ? 0 : items.size();
  }

  /**
   * Determine the view type for the cell at position (like you would do in any other adpater)
   */
  @Override public int getItemViewType(int position) {
    if (position % 2 == 0)
        return mediumRow;
    else
        return rowWithPic;
    }
  }

  /**
   * Bind the data to this view type mediumRow; MediumRowViewHolder was generated
   */
  @Override public void bindViewHolder(SampleAdapterHolders.MediumRowViewHolder vh,
        int position) {

      String str = items.get(position);
      vh.text.setText(str);
    }

    /**
     * Bind the data to this view type rowWithPic; RowWithPicViewHolder was generated
     */
    @Override public void bindViewHolder(SampleAdapterHolders.RowWithPicViewHolder vh,
        int position) {

      String str = items.get(position);
      vh.text.setText(str);
      vh.image.setImageResource(R.drawable.ic_launcher);
    }

}
