android - 如何处理Fragment类ListView的按钮事件？

Question

我在代码中使用了 Fragment。我必须在 fragment 中显示自定义 ListView。但我想处理 Button 的 onClickListener 事件，它位于 ListView 中。
如何使用这些 Button Fragment 类中的组件？因为 ListView 的行布局是另一种布局，所以我可以在 Fragment 类中使用它。
这是我的代码:

我的 fragment 类

public class VoteFragment extends Fragment
{
    ListView list_model;
    View rootView;
    private String models_name[]={"MehararPaurKamali", "Elmira Panajavi","Hanay YavariMoghadam","MehararPaurKamali"};
    private String models_adress[]={"Icon Girmfriend", "Deccan","ShivajiNagar","India"};
    int model_images[]={R.drawable.karina,R.drawable.karina,R.drawable.karina,R.drawable.karina};
    ArrayList<ModelListItem> modelList;
    ModelListItem modelItem;
    Button btn_home_model_plus;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState)
    {   
        modelList=new ArrayList<ModelListItem>();
        for(int i=0;i<models_name.length;i++)
        {   modelItem=new ModelListItem();
        modelItem.setModelname(models_name[i]);
        modelItem.setModelAdress(models_adress[i]);
        modelItem.setModel_image(model_images[i]);
        modelList.add(modelItem);

        }   

        rootView = inflater.inflate(R.layout.frag_vote,container, false);
        setUI();
        //Public void myClickHandler(){}
        return rootView;
    }
    private void setUI() 
    {
        list_model=(ListView)rootView.findViewById(R.id.list_home_model);
        btn_home_model_plus=(Button)getView().findViewById(R.id.btn_home_model_plus);

    }


}

适配器类是

public class HomeModelListAdapter extends BaseAdapter  implements OnClickListener
{

    private ArrayList<ModelListItem> modelList;
    private Context context;
    Button btn_home_model_plus,btn_home_model_vote;
    FragmentManager fragmentmanager;

    public HomeModelListAdapter(Context context, ArrayList<ModelListItem> modelList) 
    {
        this.context=context;
        this.modelList=modelList;
    }

    @Override
    public int getCount()
    {
        return modelList.size();
    }

    @Override
    public Object getItem(int arg0) 
    {
        return modelList.get(arg0);
    }

    @Override
    public long getItemId(int arg0) 
    {
        return arg0;
    }
    /*private view holder class*/
    private class ViewHolder 
    {   
        ImageView imgModelimage;
        TextView txtModeName;
        TextView txtModelAdress;
    }


    @Override
    public View getView(int position, View convertView, ViewGroup arg2)
    {  ViewHolder holder = null;

    LayoutInflater mInflater = (LayoutInflater) context
            .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);

    if (convertView == null) 
    {
        convertView = mInflater.inflate(R.layout.fram_home_list, null);
        holder = new ViewHolder();
        holder.txtModeName= (TextView) convertView.findViewById(R.id.txt_home_model_name);
        holder.txtModelAdress = (TextView) convertView.findViewById(R.id.txt_home_model_adress);
        holder.imgModelimage = (ImageView) convertView.findViewById(R.id.img_home_model);
        convertView.setTag(holder);
    }
    holder = (ViewHolder) convertView.getTag();
    holder.txtModeName.setText(modelList.get(position).getModelname());
    holder.txtModelAdress.setText(modelList.get(position).getModelAdress());
    holder.imgModelimage.setImageResource(modelList.get(position).getModel_image());
    btn_home_model_plus=(Button)convertView.findViewById(R.id.btn_home_model_plus);
    btn_home_model_vote=(Button)convertView.findViewById(R.id.btn_home_model_vote);

    btn_home_model_plus.setOnClickListener(this);


    return convertView;


    }

    @Override
    public void onClick(View v) 
    {  Fragment fragment = null;
        switch (v.getId()) 
        {
        case R.id.btn_home_model_plus:
             System.out.println("Hi.................");
            fragment = new ModelProfileDetailFragment();

            break;
        case R.id.btn_home_model_vote:

            break;
        default:
            break;
        }
        if (fragment != null)
        {   
            fragmentmanager.beginTransaction().add(R.id.fram_home, fragment).commit();
            //notifyDataSetChanged();
        }
    }

ListView 行布局

请给我建议。

好的，我认为你的问题很简单。您需要做的就是像这样编辑您的 HomeModelListAdapter 的 getView() 方法类。

public class HomeModelListAdapter extends BaseAdapter {
    .....
    .....
    @Override
    public View getView(int position, View convertView, ViewGroup arg2)
    {
        .....
        btn_home_model_plus.setOnClickListener(new OnClickListener() {  
            @Override
            public void onClick(View v) {
                //do your stuff here
            }
        });
        btn_home_model_vote.setOnClickListener(new OnClickListener() {  
            @Override
            public void onClick(View v) {
                //do your stuff here
            }
        });
        ....
    }
    ....
}

希望这能解决您的问题。
