全て、

リストに仕切りを表示したいのですが、アイテムをクリックできないようにしたいのですが、グレー表示にならないようにしたいと思っています。xml レイアウトをクリックできないように設定し、膨らませたときに無効にしようとしましたが、機能しませんでした。以下は私のコードです。

private static final String[] items = { "lorem", "ipsum", "dolor", "sit",
    "amet", "consectetuer", "adipiscing", "elit", "morbi", "vel",

どんな助けでも大歓迎です。

どうも


私は自分の答えを見つけたと信じています。機能しないということは、仕切りがクリック可能だったということです。私がしなければならなかったことは、アダプターで allItemsEnabled メソッドをオーバーライドして false を返すようにし、isEnabled メソッドで条件を作成して仕切りに対して false を返すことでした。これは、アダプターのコードを書き直したものです。

 public MyCustomAdapter() {
        mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    public void addItem(final String item) {
        mData.add(item);
        notifyDataSetChanged();
    }



    public void addSeparatorItem(final String item) {
        mData.add(item);

        // save separator position
        mSeparatorsSet.add(mData.size() - 1);
        notifyDataSetChanged();
    }

    //to make dividers not clickable
    @Override
    public boolean areAllItemsEnabled() {

        return false;
    }

    //to make dividers not clickable
    @Override
    public boolean isEnabled(int position) {

        int type = getItemViewType(position);

        if(type==0){
            return true;
        }

        return false;

    }

    @Override
    public int getItemViewType(int position) {
        return mSeparatorsSet.contains(position) ? TYPE_SEPARATOR : TYPE_ITEM;

    }

    @Override
    public int getViewTypeCount() {
        return TYPE_MAX_COUNT;
    }

    @Override
    public int getCount() {

        return mData.size();
    }

    @Override
    public String getItem(int position) {

        return mData.get(position);
    }

    @Override
    public long getItemId(int position) {

        return position;
    }



    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        int type = getItemViewType(position);
        System.out.println("getView " + position + " " + convertView + " type = " + type);
        if (convertView == null){
            holder = new ViewHolder();
            switch (type) {
            case TYPE_ITEM:
                convertView = mInflater.inflate(R.layout.row, null);
                holder.textView = (TextView) convertView.findViewById(R.id.label);
                break;

            case TYPE_SEPARATOR:
             convertView = mInflater.inflate(R.layout.item2, null);
             holder.textView = (TextView)convertView.findViewById(R.id.textSeparator);
             holder.layout = (LinearLayout) convertView.findViewById(R.id.layout);
            // holder.layout.setEnabled(false);
            //holder.textView.setEnabled(false);


             break;


            }
            convertView.setTag(holder);
        }else{
            holder = (ViewHolder) convertView.getTag();

        }
        holder.textView.setText(mData.get(position));
        return convertView;


    }

}
public static class ViewHolder {
    public TextView textView;
    public LinearLayout layout;
}

}

あなたが抱えている問題は、ClickListenerクリックできないXMLを入れているので、あなたが追加しているものに関連していると思いますが、設定した後、次のContentView行を入れています:

list.setOnItemClickListener(new OnItemClickListener() { ... }

リストをクリック可能にします。

別の投稿の私の回答に戻って、クリック可能にすべきではないをOnClickListenerに設定するだけです。したがって、次のように呼び出します。もちろん、これを行うにはビューへの参照が必要です...Viewnullview.setOnClickListener(null)
