私はウェブサイトからデータを取得しており、アンドロイドでリストビューとして表示していますが、データを使用すると、リストビューのデータも含むいくつかの html タグが表示されます。
Applicationadapter.java
public class ApplicationAdapter extends ArrayAdapter<Application>
{
private List<Application> items;
private LayoutInflater inflator;
public ApplicationAdapter(Context context, List<Application> items)
{
super(context, R.layout.activity_row, items);
this.items = items;
inflator = LayoutInflater.from(getContext());
}
@Override
public int getCount()
{
return items.size();
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
ViewHolder holder = null;
//View v = convertView;
if ( convertView == null )
{
convertView = inflator.inflate(R.layout.activity_row, null);
LayoutInflater li = LayoutInflater.from(getContext());
//convertView = inflator.inflate(R.layout.app_custom_list, null);
holder = new ViewHolder();
holder.text1 = (TextView) convertView.findViewById(R.id.text1);
holder.chk = (CheckBox) convertView.findViewById(R.id.checkbox);
/*holder.chk
.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
/*@Override
public void onCheckedChanged(CompoundButton view,
boolean isChecked) {
int getPosition = (Integer) view.getTag();
items.get(getPosition).setSelected(view.isChecked());
}
});*/
convertView.setTag(holder);
convertView.setTag(R.id.text1, holder.text1);
convertView.setTag(R.id.checkbox, holder.chk);
}else {
holder = (ViewHolder) convertView.getTag();
}
Application app = items.get(position);
holder.chk.setTag(position);
holder.text1.setText(items.get(position).getContent());
//holder.chk.setChecked(items.get(position).isSelected());
if ( app != null )
{
TextView titleText = (TextView) convertView.findViewById(R.id.titleTxt);
if ( titleText != null )
titleText.setText(Html.fromHtml(app.getContent()).toString());
//titleText.setText(app.getContent());
//holder.chk.setChecked(((View) Html.fromHtml(app.getContent())).isSelected());
}
return convertView;
}
static class ViewHolder {
public TextView text1;
public CheckBox chk;
}
//return convertView;
}
リストビューでhtmlタグを削除するために1行を使用しましたが、リストビューのようにhtmlタグが表示されていてもわかりません
。私の出力はリストビューでそのように表示されます hi <br>bye <br>'hello <br>.しかし、リストビューにそのhtmlタグを表示したくないので、どうすれば問題を解決できますか。

リストビューのみのデータを表示したいのですが、htmltags は必要ありません。
if ( titleText != null ) then
titleText.setText(Html.fromHtml(app.getContent()).toString());またはこのように書きたい場合、どの行が正しいか知りたいholder.text1.setText(Html.fromHtml(app.getContent()).toString());
