SVG url 图像未显示在 RecyclerView 中

Question

我有一些 url 字符串，一些以 .png 结尾，而另一些以 .svg 结尾。 .png 可以很好地加载到 recyclerview 中，但 .svg 却无处可见。我搜索了很多论坛，但目前还没有任何效果。

我的 recyclerviewadapter 的 onBindViewHolder 中有以下代码，用于确定 url 是否为 .svg。如果有人有任何想法，我将非常感激。

    String[] homeUrlSplit = mData.get(i).getHomeTeamBadge().split("\\.");

    String homeImageType = homeUrlSplit[homeUrlSplit.length-1];

    if(homeImageType.equals("svg")){
        // do something here
    }
    else {
        Glide
                .with(mContext)
                .load(mData.get(i).getHomeTeamBadge())
                .into(myViewHolder.homeTeamBadge);
    }

谢谢

编辑：我不太了解“可能重复”答案下的 cmets 中包含的解决方案。如果有人知道任何其他解决方案，或者能够用外行的方式解释这个特定的解决方案，我将非常感激。

这是适配器设置：

    RecyclerViewAdapterFixtures recyclerViewAdapterFixtures = new RecyclerViewAdapterFixtures(getContext(), matchesList, getActivity());
    recyclerViewFixtures.setLayoutManager(new LinearLayoutManager(getActivity()));
    recyclerViewFixtures.setAdapter(recyclerViewAdapterFixtures);

这里是recylerviewadapter代码

public class RecyclerViewAdapterFixtures extends RecyclerView.Adapter<RecyclerViewAdapterFixtures.MyViewHolder> {

Context mContext;
List<Match> mData;
Activity mActivity;

public RecyclerViewAdapterFixtures(Context mContext, List<Match> mData, Activity mActivity) {
    this.mContext = mContext;
    this.mData = mData;
    this.mActivity = mActivity;
}

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

    View v;
    v = LayoutInflater.from(mContext).inflate(R.layout.item_fixture, viewGroup, false);
    MyViewHolder vHolder = new MyViewHolder(v);

    return vHolder;
}

@Override
public void onBindViewHolder(@NonNull MyViewHolder myViewHolder, final int i) {

    myViewHolder.textViewHomeTeam.setText(mData.get(i).getHomeTeamName());

    String[] homeUrlSplit = mData.get(i).getHomeTeamBadge().split("\\.");

    String homeImageType = homeUrlSplit[homeUrlSplit.length-1];

    if(homeImageType.equals("svg")){

        SvgLoader.pluck()
                .with(mActivity)
                .setPlaceHolder(R.mipmap.ic_launcher, R.mipmap.ic_launcher)
                .load(mData.get(i).getHomeTeamBadge(), myViewHolder.homeTeamBadge);

    }
    else {
        Glide
                .with(mContext)
                .load(mData.get(i).getHomeTeamBadge())
                .into(myViewHolder.homeTeamBadge);
    }
}

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

public static class MyViewHolder extends RecyclerView.ViewHolder {

    private TextView textViewVersus;
    private EditText homeTeamScore;
    private EditText awayTeamScore;
    private TextView textViewHomeTeam;
    private TextView textViewAwayTeam;
    private ImageView homeTeamBadge;
    private ImageView awayTeamBadge;

    public MyViewHolder(@NonNull View itemView) {
        super(itemView);

        textViewVersus = (TextView) itemView.findViewById(R.id.textViewVersus);
        homeTeamScore = (EditText) itemView.findViewById(R.id.homeTeamScore);
        awayTeamScore = (EditText) itemView.findViewById(R.id.awayTeamScore);
        textViewHomeTeam = (TextView) itemView.findViewById(R.id.textViewHomeTeam);
        textViewAwayTeam = (TextView) itemView.findViewById(R.id.textViewAwayTeam);
        homeTeamBadge = (ImageView) itemView.findViewById(R.id.homeTeamBadge);
        awayTeamBadge = (ImageView) itemView.findViewById(R.id.awayTeamBadge);

    }
}

}

把它放在你的 build.gradle 文件（应用程序级别）的依赖中：

implementation 'com.github.ar-android:AndroidSvgLoader:1.0.1'

在 build.gradle 项目级别你应该添加 maven { url 'https://jitpack.io' } 所以在大多数情况下它看起来像这样

allprojects {
  repositories {
    google()
    jcenter()
   maven { url 'https://jitpack.io' }
  }
 }

然后

String[] homeUrlSplit = mData.get(i).getHomeTeamBadge().split("\\.");

 String homeImageType = homeUrlSplit[homeUrlSplit.length - 1];

 if (homeImageType.equals("svg")) {
  SvgLoader.pluck()
   .with(mActivity) // ur activity
   .setPlaceHolder(R.mipmap.ic_launcher, R.mipmap.ic_launcher)//use ur place holder
   .load(mData.get(i).getHomeTeamBadge(), myViewHolder.homeTeamBadge);
 } else {
  Glide
   .with(mContext)
   .load(mData.get(i).getHomeTeamBadge())
   .into(myViewHolder.homeTeamBadge);
 }

如果你有，请从你的项目中删除 Glide 依赖项实现，因为 AndroidSVGLoader 已经有了它们
