Wie man clickablespan auf eine Textansicht in RecyclerView setzt

Question

Ich habe Recyclerviwq mit Textvies, und der Text in der Textansicht hat URLs und ich möchteclickablespan in der Textansicht einstellen und die URLs erfassen.

Ich verwende diese accepted answer und es funktioniert nicht.

Dies ist mein Code:

public class LibAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> { 
    private Context mContext; 
    private List<LibItem> mLibItemList; 

    private final int HEAD_VIEW = 0; 
    private final int LIB_VIEW = 1; 

    public LibAdapter(List<LibItem> libItems, Context context) { 
     super(); 
     this.mLibItemList = libItems; 
     this.mContext = context; 
    } 

    @Override 
    public int getItemViewType(int position) { 
     if (isPositionItem(position)) { 
      return HEAD_VIEW; 
     } 
     return LIB_VIEW; 
    } 

    private boolean isPositionItem(int position) { 
     return position == 0; 
    } 

    @Override 
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     if (viewType == LIB_VIEW) { 
      View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.library_item, parent, false); 
      return new LibHolder(view); 
     } else if (viewType == HEAD_VIEW) { 
      View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.about_hedaer, parent, false); 
      return new HeadHolder(view); 
     } 
     return null; 
    } 

    @Override 
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { 
     if (holder instanceof LibHolder) { 
      final LibItem libItem = mLibItemList.get(position); 
      ((LibHolder) holder).libName.setText(libItem.getLibName()); 
      ((LibHolder) holder).libCopy.setText(Html.fromHtml(libItem.getLibCopy())); 
      ((LibHolder) holder).libLic.setText(mContext.getString(R.string.proj_license)); 

      setTextViewHTML(((LibHolder) holder).libWeb, mContext.getString(R.string.proj_code, libItem.getLibWebs())); 
      ((LibHolder) holder).libLic.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        Log.d("LibAdapter", "License of " + libItem.getLibName() + "clicked"); 
       } 
      }); 
     } else if (holder instanceof HeadHolder){ 
      String versionCode = BuildConfig.VERSION_NAME; 
      ((HeadHolder) holder).abtVersion.setText(mContext.getString(R.string.app_version, versionCode)); 
     } 
    } 

    protected void makeLinkClickable(SpannableStringBuilder strBuilder, final URLSpan span) 
    { 
     int start = strBuilder.getSpanStart(span); 
     int end = strBuilder.getSpanEnd(span); 
     int flags = strBuilder.getSpanFlags(span); 
     ClickableSpan clickable = new ClickableSpan() { 
      public void onClick(View view) { 
       Log.d("LipAdapter", span.getURL()); 
      } 
     }; 
     strBuilder.setSpan(clickable, start, end, flags); 
     strBuilder.removeSpan(span); 
    } 

    protected void setTextViewHTML(TextView text, String html) 
    { 
     CharSequence sequence = Html.fromHtml(html); 
     SpannableStringBuilder strBuilder = new SpannableStringBuilder(sequence); 
     URLSpan[] urls = strBuilder.getSpans(0, sequence.length(), URLSpan.class); 
     for(URLSpan span : urls) { 
      makeLinkClickable(strBuilder, span); 
     } 
     text.setText(strBuilder); 
     text.setMovementMethod(LinkMovementMethod.getInstance()); 
    } 



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

    public class LibHolder extends RecyclerView.ViewHolder { 
     @BindView(R.id.lib_name) TextView libName; 
     @BindView(R.id.lib_website) TextView libWeb; 
     @BindView(R.id.lib_copyright) TextView libCopy; 
     @BindView(R.id.lib_license) TextView libLic; 

     public LibHolder(View itemView) { 
      super(itemView); 
      ButterKnife.bind(this, itemView); 
     } 
    } 

    public class HeadHolder extends RecyclerView.ViewHolder { 
     @BindView(R.id.abt_version) TextView abtVersion; 

     public HeadHolder(View itemView) { 
      super(itemView); 
      ButterKnife.bind(this, itemView); 
     } 
    } 
} 

Der Text ganz in Ordnung gesetzt ist, aber die Verbindung verweigert angeklickt werden. bitte haben sie eine lösung dafür?

Answer 1

Sie versuchten dies ::

protected void makeLinkClickable(SpannableStringBuilder strBuilder, final URLSpan span) 
{ 
    int start = strBuilder.getSpanStart(span); 
    int end = strBuilder.getSpanEnd(span); 
    int flags = strBuilder.getSpanFlags(span); 
    ClickableSpan clickable = new ClickableSpan() { 
     public void onClick(View view) { 
      Log.d("LipAdapter", span.getURL()); 
     } 
    }; 
    strBuilder.setSpan(clickable, start, end, flags); 
    strBuilder.removeSpan(span); 
} 

Aber Sie müssen etwas tun ::

protected void makeLinkClickable(SpannableStringBuilder strBuilder, final URLSpan span) 
{ 
    int start = strBuilder.getSpanStart(span); 
    int end = strBuilder.getSpanEnd(span); 
    int flags = strBuilder.getSpanFlags(span); 


    ClickableSpan clickable = new ClickableSpan() { 
     @Override 
     public void onClick(View widget) { 
      Log.d("LipAdapter", span.getURL()); 
     } 

     @Override 
     public void updateDrawState(TextPaint ds) { 
      super.updateDrawState(ds); 
     } 
    }; 

    strBuilder.setSpan(clickable, start, end, flags); 
    strBuilder.removeSpan(span); 
} 

hoffen, dass es für andere arbeiten

Answer 2

ich hatte das gleiche Problem und musste sequence zu Spannable schreiben, damit es funktioniert.

Ersetzen Sie einfach

SpannableStringBuilder strBuilder = new SpannableStringBuilder(sequence); 

mit

Spannable strBuilder = (Spannable) sequence;
