Question

我正在做自定义ListView。我已经在包含ListView的Fragment中设置了一个自定义适配器，但是当我尝试在列表的项目上设置click事件时，它没有响应。

这是fragement的onCreateView函数

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
     final View v = (View) inflater.inflate(R.layout.fragment_club, container, false);

    listView = (ListView) v.findViewById(R.id.list);

    c = new CustomListAdapter(this, clubList);
    listView.setAdapter(c);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                                long id) {

                Log.i("Infox", "KRIM");
            }
        });

    return v ;
}

这是我的自定义适配器：

public class CustomListAdapter extends BaseAdapter {
private Fragment fragment;
private LayoutInflater inflater;
private List<Club> cItems;
ImageView img;
Context context;
ListView lv;

public CustomListAdapter(Fragment fragment, List<Club> cItems) {
    this.fragment = fragment;
    this.cItems = cItems;
}

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

@Override
public Object getItem(int location) {
    return cItems.get(location);
}

@Override
public long getItemId(int position) {
    return position;
}

public static Bitmap getBitmapFromURL(String src) {
    try {
        Log.e("src", src);
        URL url = new URL(src);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);
        Log.e("Bitmap","returned");
        return myBitmap;
    } catch (IOException e) {
        e.printStackTrace();
        Log.e("Exception",e.getMessage());
        return null;
    }
}

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

    if (inflater == null) {
         context = fragment.getActivity();

        inflater = (LayoutInflater) LayoutInflater.from(context);
    }

    if (convertView == null)
        convertView = inflater.inflate(R.layout.list_row, null);

    img = (ImageView) convertView.findViewById(R.id.thumbnail);
    TextView nomC = (TextView) convertView.findViewById(R.id.title);
    TextView slogan = (TextView) convertView.findViewById(R.id.slogan);
    TextView descipline = (TextView) convertView.findViewById(R.id.desc);
    Button join = (Button) convertView.findViewById(R.id.joinB);


    View v = (View) inflater.inflate(R.layout.fragment_club,parent,false);

    lv = (ListView) v.findViewById(R.id.list);

    // getting movie data for the row
    final Club m = cItems.get(position);


    //Set the button click event
    join.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Toast.makeText(context,
                    m.getNomC(), Toast.LENGTH_LONG).show();
        }
    });

   /* lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                                long id) {

            Log.i("Infox", "KRIM");
        }
    });*/


    // thumbnail image
    img.setImageBitmap(getBitmapFromURL(m.getThumbnailUrl()));

    // Nom du club
    nomC.setText(m.getNomC());

    // Slogan Club
    slogan.setText(m.getSlogan());

    //Disciplines des clubs
    descipline.setText(m.getDesc());


    return convertView;
}

}

PS：就像你在评论代码中看到的那样，我试图在我的自定义适配器中做到这一点，但我认为这是一个绝望的操作

Answer 1

如果您想要实现项目点击以及按钮单击，则执行相同的操作以转换为加入按钮。暗示onClickListener转换为。

convertView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        Log.i("Infox", "KRIM");
    }
});

Answer 2

您应该从适配器中删除onclick，之后您应该使用setOnItemClickListener

ClickView上的Click事件没有响应
