我一直在使用OnCreate()和Adapter类从Model方法创建并填充Listviews。
但是，我需要创建一个Tablayout并在每个Tab中显示一个ListView，并且由于每个Tab都扩展了Fragment，所以它不能以相同的方式工作。
这是我的 Tab1 课：
public class Tab1 extends Fragment {
ArrayList<Model> model;
private static Adapter adapter;
ListView listView;
//Overriden method onCreateView
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.tab1, container, false);
listView=(ListView)view.findViewById(R.id.list);
model = new ArrayList<>();
model.add(new Model("AAA","aaa",23));
model.add(new Model("BBB","bbb",30));
model.add(new Model("CCC","ccc",23));
adapter = new Adapter(model, getActivity());
listView.setAdapter(adapter);
return view;
}
}
我的适配器类：
public class Adapter extends ArrayAdapter<Model> implements View.OnClickListener{
private ArrayList<Model> dataSet;
Context mContext;
// View lookup cache
private class ViewHolder {
TextView txtNom;
TextView txtPrenom;
TextView txtAge;
}
public Adapter(ArrayList<Model> data, Context context) {
super(context, R.layout.row_item, data);
this.dataSet = data;
this.mContext=context;
//startUpdateTimer();
}
@Override
public void onClick(View v) {
int position=(Integer) v.getTag();
Object object= getItem(position);
Model Model=(Model)object;
switch (v.getId())
{
case R.id.AgeTV:
Snackbar.make(v, "Age : " +Model.getAge(), Snackbar.LENGTH_LONG)
.setAction("No action", null).show();
break;
}
}
private int lastPosition = -1;
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// Get the data item for this position
Model model = getItem(position);
// Check if an existing view is being reused, otherwise inflate the view
final ViewHolder viewHolder; // view lookup cache stored in tag
final View result;
if (convertView == null) {
viewHolder = new ViewHolder();
LayoutInflater inflater = LayoutInflater.from(getContext());
convertView = inflater.inflate(R.layout.row_item, parent, false);
viewHolder.txtNom = (TextView) convertView.findViewById(R.id.NomTV);
viewHolder.txtPrenom = (TextView) convertView.findViewById(R.id.PrenomTV);
viewHolder.txtAge = (TextView) convertView.findViewById(R.id.AgeTV);
result=convertView;
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
result=convertView;
}
lastPosition = position;
viewHolder.txtNom.setText(model.getNom());
viewHolder.txtPrenom.setText(model.getPrenom());
viewHolder.txtAge.setText(model.getAge());
viewHolder.txtAge.setOnClickListener(this);
viewHolder.txtAge.setTag(position);
// Return the completed view to render on screen
return convertView;
}
}
我的 Model 类：
public class Model {
String Nom, Prenom;
int Age;
public Model(String nom, String prenom, int age) {
Nom = nom;
Prenom = prenom;
Age = age;
}
public String getNom() {
return Nom;
}
public void setNom(String nom) {
Nom = nom;
}
public String getPrenom() {
return Prenom;
}
public void setPrenom(String prenom) {
Prenom = prenom;
}
public int getAge() {
return Age;
}
public void setAge(int age) {
Age = age;
}
}
它不起作用，我也没弄错我得到的错误：

似乎片段处理方式不同。所以我想知道我在想什么。 如果根本不是从Tablayout填充每个Tab中的ListView的正确方法，我想知道我该怎么做。
