Question

正如标题所示，我试图在列表视图中添加其他自定义行以允许更多自定义。我目前有一个自定义行设置到列表视图，据我们所知，将根据输入的信息量不断重复。既然我想扩展列表视图以显示多个自定义行，我就会陷入调整代码的行列，如果有人可以看看，我会很感激。

我已解释了我目前的设置。

首先，我们有视图持有者本身作为设置信息的中间人。

public class ViewHolderWine {

public ImageView wineImage;
public TextView wineName;
public TextView  wineDes;
public TextView  winePrice;


public void setDataIntoViewHolder (List_String listString ){

    wineImage.setImageResource(listString.getIcon_wine());
    wineName.setText(listString.getWineName());
    wineDes.setText(listString.getWinedes());
    winePrice.setText(listString.getWinePrices());

}

其次我们有我的List_String，其中已经创建了getter和setter。

public class List_String {

int icon_wine;
String wineName;
String winedes;
String winePrices;


public List_String(int icon_wine, String wineName, String winedes, String winePrices) {
    this.icon_wine = icon_wine;
    this.wineName = wineName;
    this.winedes = winedes;
    this.winePrices = winePrices;

}

public String getWinePrices() {
    return winePrices;
}

public void setWinePrices(String winePrices) {
    this.winePrices = winePrices;
}

etc......

我们接下来有ListFragment

 public class List extends ListFragment {

java.util.List<List_String> lst;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

  listData();
    // Adapter custom;


     Adapter myAdapter = new Adapter(getActivity(), R.layout.custom_list, lst);

    setListAdapter(myAdapter);

    return super.onCreateView(inflater, container, savedInstanceState);

}


public void listData() {

    lst = new ArrayList<List_String>();

    lst.add(new List_String(R.drawable.thumb, etc....

最后，我使用适配器将所有部分组合在一起。

 public class Adapter extends ArrayAdapter<List_String> {

List<List_String> lstWine;
LayoutInflater inflater;

public Adapter(Context context, int resource, java.util.List<List_String> objects) {
    super(context, resource, objects);


    lstWine = objects;
    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}


@Override
public View getView(int position, View convertView, ViewGroup parent) {

    View view = convertView;

    ViewHolderWine viewholder;


    if (view == null){

        viewholder = new ViewHolderWine();


                view = inflater.inflate(R.layout.custom_list, null);

                viewholder.wineImage = (ImageView) view.findViewById(R.id.wineImage);
                viewholder.wineName = (TextView) view.findViewById(R.id.wineName);
                viewholder.wineDes = (TextView) view.findViewById(R.id.wineDes);
                viewholder.winePrice = (TextView) view.findViewById(R.id.winePrice);



        view.setTag(viewholder);

    }else{

        viewholder = (ViewHolderWine) view.getTag();

    }

    List_String list = lstWine.get(position);
    viewholder.setDataIntoViewHolder(list);


    return view;

}

托管列表视图的活动的布局就像这样

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:app="http://schemas.android.com/apk/res-auto"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:weightSum="1">

     <ListView
          android:id="@+id/list"
          android:layout_width="match_parent"
          android:layout_height="wrap_content">
     </ListView>
     <ListView
          android:id="@+id/list2"
          android:layout_width="match_parent"
          android:layout_height="wrap_content">
     </ListView>
</LinearLayout>

在您的活动课程中

//populate your first list
    myList.add(0, new Model("Full name 1", "Good"));
    myList.add(1, new Model("Full name 2", "Bad"));
    myList.add(2, new Model("Full name 3", "Worse"));
    myList.add(3, new Model("Full name 4", "Mediocre"));

//populate your second list
    myList2.add(0, new Model2("Full name 5", true));
    myList2.add(1, new Model2("Full name 6", true));
    myList2.add(2, new Model2("Full name 7", false));

//initialize adapters
    adapter = new mAdapter(StartActivity.this,myList);
    adapter2 = new mAdapter2(StartActivity.this,myList2);

//retrieve the list views
    lv= (ListView) findViewById(R.id.list);
    lv2= (ListView) findViewById(R.id.list2);

//set the adapters
    lv.setAdapter(adapter);
    lv2.setAdapter(adapter2);

如何将其他自定义行添加到列表视图？
