如何在HorizontalGridView中設置水平間距？

全片段佈局：Fragment layout 如何在HorizontalGridView中設置水平間距？

我想意見分開所以就卡之間的水平突破15dp，但現在它看起來像這樣：Overlapped views

我已經嘗試添加機器人：horizontalSpacing （就像我在常規GridView中那樣做）屬性到XML，但沒有任何事情發生。從LayoutManager使用childrenOffsetHorizontal也沒有按預期給出結果。

這裏是我的片段代碼：

public class TvDetailsFragment extends Fragment { 

private HorizontalGridView gridView; 
private SeasonsListAdapter seasonsListAdapter; 

public TvDetailsFragment(){ 

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 

    // Get the arguments from the ShowDetailsActivity. 
    Bundle args = getArguments(); 
    View rootView = inflater.inflate(R.layout.fragment_tv_details, container, false); 
    gridView = (HorizontalGridView)rootView. 
      findViewById(R.id.tv_details_seasons_gridview); 
    gridView.setLayoutManager(new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false)); 
    gridView.getLayoutManager().set 

    FetchTvDetailsById fetchDetails = new FetchTvDetailsById(getContext()); 
    fetchDetails.execute(args.getString("SHOW_ID")); 

    return rootView; 
} 

public void populateView(TvClass tvDetails) { 

    Activity mActivity = getActivity(); 

    ImageView imageView = (ImageView)mActivity.findViewById(R.id.tv_details_imageview); 
    Picasso.with(mActivity).load(tvDetails.getShowPosterLink()) 
      .fit() 
      .into(imageView); 

    TextView titleView = (TextView) mActivity.findViewById(R.id.tv_details_title_textview); 
    titleView.setText(Html.fromHtml("<b>" + "Original title: " + "</b> <br>" 
      + tvDetails.getShowOriginalTitle())); 

    TextView dateView = (TextView) mActivity.findViewById(R.id.tv_details_date_textview); 
    dateView.setText(Html.fromHtml("<b>" + "Release date: " + "</b> <br>" 
      + tvDetails.getShowReleaseDate())); 

    TextView voteView = (TextView) mActivity.findViewById(R.id.tv_details_vote_textview); 
    voteView.setText(Html.fromHtml("<b>" + "Vote average: " + "</b> <br>" 
      + Double.toString(tvDetails.getShowVoteAverage()) + "/10")); 

    TextView overviewView = (TextView) mActivity.findViewById(R.id.tv_details_overview_textview); 
    overviewView.setText(tvDetails.getShowOverview()); 

    // Make the cards visible after loading the content. 
    CardView posterCard = (CardView)mActivity.findViewById(R.id.tv_details_poster_card); 
    posterCard.setVisibility(View.VISIBLE); 

    CardView infoCard = (CardView)mActivity.findViewById(R.id.tv_details_info_card); 
    infoCard.setVisibility(View.VISIBLE); 

    CardView detailsCard = (CardView)mActivity.findViewById(R.id.tv_details_overview_card); 
    detailsCard.setVisibility(View.VISIBLE); 

    ArrayList<ShowThumbnail> seasonThumbnails = tvDetails.getSeasonsThumbnails(); 
    seasonsListAdapter = new SeasonsListAdapter(getActivity(), seasonThumbnails); 
    gridView.setAdapter(seasonsListAdapter); 

    // Dismiss the loading panel. 
    RelativeLayout loadingPanel = (RelativeLayout)mActivity.findViewById(R.id.tv_details_loading_panel); 
    loadingPanel.setVisibility(View.GONE); 

}

</RelativeLayout>

和定製RecyclerView.Adapter：

public class SeasonsListAdapter extends RecyclerView.Adapter<SeasonsListAdapter.SeasonViewHolder> { 

private ArrayList<ShowThumbnail> showThumbnailsList; 
private Context ctx; 

class SeasonViewHolder extends RecyclerView.ViewHolder { 

    protected ImageView imageView; 
    protected TextView textView; 

    public SeasonViewHolder(View view) { 
     super(view); 
     this.imageView = (ImageView) view.findViewById(R.id.image_item_imageview); 
     this.textView = (TextView) view.findViewById(R.id.image_item_textview); 
    } 
} 

public SeasonsListAdapter(Context ctx, ArrayList<ShowThumbnail> showThumbnails) { 
    this.showThumbnailsList = showThumbnails; 
    this.ctx = ctx; 
} 

@Override 
public SeasonViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) { 

    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.image_item, null); 
    SeasonViewHolder seasonViewHolder = new SeasonViewHolder(view); 
    return seasonViewHolder; 
} 

@Override 
public void onBindViewHolder (SeasonViewHolder seasonViewHolder, int i) { 

    ShowThumbnail showThumbnailItem = showThumbnailsList.get(i); 
    Picasso.with(ctx).load(showThumbnailItem.getShowPosterLink()) 
      .fit() 
      .into(seasonViewHolder.imageView); 
    seasonViewHolder.textView.setText(showThumbnailItem.getShowTitle()); 
} 

@Override 
public int getItemCount() { 
    return (null != showThumbnailsList ? showThumbnailsList.size() : 0); 
}

你的XML是錯誤的。
爲您的卡添加保證金。不是你的圖片。這將提供卡之間所需的間距！

<android.support.v7.widget.CardView 
    android:id="@+id/tv_details_poster_card" 
    android:layout_width="150dp" 
    android:layout_height="200dp" 
    android:visibility="invisible" 
    card_view:cardCornerRadius="4dp" 
    android:layout_marginLeft="10dp" 
    android:layout_marginRight="10dp" 
    android:layout_marginTop="10dp"> 

    <ImageView 
     android:id="@+id/tv_details_imageview" 
     android:layout_width="130dp" 
     android:layout_height="180dp" /> 

</android.support.v7.widget.CardView>

這不會是因爲tv_details_poster_card與HorizontalGridView無關。我編輯了我的問題，以便可以看到整個Fragment佈局的樣子。 – mordowiciel

您是否嘗試過編程方式使用HorizontalGridView的setHorizontalSpacing()方法做什麼呢？
