java - ListView 项目没有点击

Question

我有 ListView fragment 。具有 web-html 链接的 ListViewItem 存在问题。不可点击。当 android:autoLink="web" "android:descendantFocusability="blocksDescendants" 没有帮助时，@drawable/items_selector 不工作并且不调用 onItemClick。并且 this解决方案不起作用。我需要像“视频群聊”这样的 ListView 项目或其他选择了工作项目和工作 html 链接等的应用程序。请帮助我。操作系统版本为 Android 5.1.1

SIMPLE XML...但也行不通。

 <LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:descendantFocusability="blocksDescendants" 
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:background="@drawable/items_selector"
  android:orientation="vertical"
  android:padding="2dp">

<TextView
    android:id="@+id/themeText"
    android:autoLink="web"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="@dimen/layout_margin"
    android:paddingLeft="@dimen/layout_margin"
    android:paddingRight="@dimen/layout_margin"
    android:text="Bla bla bla"/>

</LinearLayout>

适配器代码:

 private class ThemesAdapter extends BaseAdapter {
    private LayoutInflater layoutInflater;
    private ArrayList<ForumThemeItem> mThemes;

    public ThemesAdapter(Context context, ArrayList<ForumThemeItem> themes) {
        this.mThemes = themes;
        layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    public int getCount() {
        if (mThemes != null) {
            return mThemes.size();
        }
        return 0;
    }

    public void add(ArrayList<ForumThemeItem> themes){
        mThemes.addAll(themes);
    }

    public ForumThemeItem getItem(int position) {
        return mThemes.get(position);
    }

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

    public View getView(int position, View convertView, ViewGroup parent) {
        ForumThemeItem mTheme = getItem(position);
        ThemesViewHolder viewHolder;

        if (convertView == null) {
            viewHolder = new ThemesViewHolder();
            convertView = layoutInflater.inflate(R.layout.item_theme, null);
            convertView.findViewById(R.id.ratingLayout).setVisibility(View.GONE);
            viewHolder.themePart = (TextView)convertView.findViewById(R.id.themePart);
            viewHolder.themeText = (TextView)convertView.findViewById(R.id.themeText);
            viewHolder.themeDate = (TextView)convertView.findViewById(R.id.themeDate);
            viewHolder.themeDateUpdate = (TextView)convertView.findViewById(R.id.themeDateUpdate);
            viewHolder.userNick = (TextView)convertView.findViewById(R.id.userNick);
            viewHolder.vote = (ImageView)convertView.findViewById(R.id.vote);
            viewHolder.viewsCount =(TextView)convertView.findViewById(R.id.viewsCount);
            viewHolder.replyCount =(TextView)convertView.findViewById(R.id.replyCount);
            convertView.setTag(viewHolder);
        }else{
            viewHolder = (ThemesViewHolder) convertView.getTag();
        }


        viewHolder.vote.setVisibility(mTheme.isVote() ? View.VISIBLE : View.GONE);
        viewHolder.themeText.setText(Html.fromHtml(mTheme.getText()));
        viewHolder.userNick.setText(mTheme.getNick());
        viewHolder.themeDate.setText(mTheme.getCreateDate()+",");
        viewHolder.themeDateUpdate.setText(String.format("обн.: %s",mTheme.getDateUpdate()));
        viewHolder.viewsCount.setText(String.format("%s",mTheme.getViewsCount()));
        viewHolder.replyCount.setText(String.format("%s", mTheme.getRepliesCount()));

        if(mTheme.getPartSubName()==null){
            viewHolder.themePart.setText(mTheme.getPartName());
        }else{
            viewHolder.themePart.setText(String.format("%s (%s)",mTheme.getPartName(),mTheme.getPartSubName()));
        }

        if(!mTheme.isAnonymously()){
            switch (mTheme.getGender()){
                case "f":
                    viewHolder.userNick.setTextColor(getResources().getColor(R.color.woman));
                    break;
                case "m":
                    viewHolder.userNick.setTextColor(getResources().getColor(R.color.man));
                    break;
                case "n":
                    viewHolder.userNick.setTextColor(getResources().getColor(R.color.it));
                    break;
            }
        }else{
            viewHolder.userNick.setTextColor(getResources().getColor(R.color.default_text_color));
        }

        return convertView;
    }

    class ThemesViewHolder {
        TextView themePart;
        TextView themeDate;
        TextView themeDateUpdate;
        TextView themeText;
        TextView userNick;
        ImageView vote;
        TextView viewsCount;
        TextView replyCount;
    }
}

我修改适配器。

在适配器中:

  viewHolder.themeText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(mTextClickListener!=null){
                    mTextClickListener.onTextClick(position);
                }
            }
        });

Activity 中:

@Override
public void onTextClick(int position) {
    mThemesList.performItemClick(mThemesList.getAdapter().getView(position, null, null), position, position);
}

但项目未被选中(无填充灰色)

如果你想点击整行，只需实现OnClickListener。

如果您想单击整行和行内的链接(我想这就是您想要的):

• 您必须创建一个自定义行项目
• 创建一个接口(interface)
• 将该接口(interface)监听器发送到适配器
• 检查文本是否包含链接。如果是这样，请使用那个监听器发送你到链接

像这样:

interface OnWebLinkClick(){
    void onWebLinkClick(String url);
}

在您的适配器上，您为 OnWebLinClick 监听器 添加了另一个参数:

public ThemesAdapter(Context context, ArrayList<ForumThemeItem> themes, OnWebLinClick mListener){
   this.mListener = mListener;   
} 

检查文本是否包含链接并执行onWebLinkClick(urlOnTextView)并在webView中打开它
