在不同的分类活动中显示不同的列表项

问题描述

现在，我想列出不同类别的项目，例如：其中一家医院，其中一项必须包含名称，地址和电话号码，如果索引中的一种文本不可见，则我在适配器中创建了此if语句其他人，但对我没有任何帮助code

public class Data {
private String placeWord;
private String addressWord;
private String reason = ONE_TEXT;
private static final String ONE_TEXT = "ah";


public Data(String mPlaceWord,String mAddressWord){
    placeWord = mPlaceWord;
    addressWord = mAddressWord;
}
public Data(String theReson){
   reason = theReson;
}
public String getPlaceWord(){
    return placeWord;
}
public String getAddressWord(){
    return addressWord;
}
public String getReason(){return reason;}

public boolean oneText(){
    return  reason != ONE_TEXT;
}

public class DataAdapter extends ArrayAdapter {
    private int mColorResourceId;

    public DataAdapter(@NonNull Context context,ArrayList<Data> resource,int ColorResourceId) {
        super(context,resource);
    mColorResourceId =  ColorResourceId ;
    }
    @NonNull
    @Override
    public View getView(int position,@Nullable View convertView,@NonNull ViewGroup parent) {
        View listitem = convertView;
        if( listitem == null){
            listitem = LayoutInflater.from(getContext()).inflate(R.layout.list_item,parent,false);
        }
        Data currentword = (Data) getItem(position);
        TextView pd = (TextView) listitem.findViewById(R.id.placetxt);
        pd.setText(currentword.getPlaceWord());
        TextView ad = (TextView) listitem.findViewById(R.id.adddrestxt);
        ad.setText(currentword.getAddressWord());
        if (currentword.oneText()){
            TextView ps = (TextView) listitem.findViewById(R.id.placetxt);
            ps.setText(currentword.getReason());
        } else{
            pd.setVisibility(View.GONE);
            ad.setVisibility(View.GONE);
       }
        View textContainer = listitem.findViewById(R.id.list_item);
        // Find the color that the resource ID maps to
        int color = ContextCompat.getColor(getContext(),mColorResourceId);
        // Set the background color of the text container View
        textContainer.setBackgroundColor(color);
        return listitem;
    }
}

解决方法

使用回收站视图，并将此逻辑添加到其适配器中。
