我在每个 listview 项目行中使用图像按钮，并尝试使用 Button onClick 侦听器启动新活动，但得到：- 源附件不包含 ComponentName.class 的源

package com.example.androidhive;

public class LazyAdapter extends BaseAdapter {

protected static final Context Context = null;
private Activity activity;
private ArrayList<HashMap<String, String>> data;
private static LayoutInflater inflater=null;
public ImageLoader imageLoader; 

public LazyAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
    activity = a;
    data=d;
    inflater = (LayoutInflater)activity.
  getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    imageLoader=new ImageLoader(activity.getApplicationContext());
}

public int getCount() {
    return data.size();
}

public Object getItem(int position) {
    return position;
}

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

public View getView(int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    if(convertView==null)
        vi = inflater.inflate(R.layout.list_row, null);

    TextView title = (TextView)vi.findViewById(R.id.title); 
    TextView artist = (TextView)vi.findViewById(R.id.description); 
    TextView duration = (TextView)vi.findViewById(R.id.cost); 
    TextView regular = (TextView)vi.findViewById(R.id.regular); 
    TextView small = (TextView)vi.findViewById(R.id.small); 
    TextView large = (TextView)vi.findViewById(R.id.large); 
    ImageView thumb_image=(ImageView)vi.findViewById(R.id.item_image); 
    ImageButton btn_add=(ImageButton)vi.findViewById(R.id.addorder);





    HashMap<String, String> song = new HashMap<String, String>();

    song = data.get(position);

    // Setting all values in listview
    title.setText(song.get(CustomizedListView.KEY_TITLE));
    artist.setText(song.get(CustomizedListView.KEY_DESC));
    duration.setText(song.get(CustomizedListView.KEY_COST));
    regular.setText(song.get(CustomizedListView.KEY_REGULAR));
    small.setText(song.get(CustomizedListView.KEY_SMALL));
    large.setText(song.get(CustomizedListView.KEY_LARGE));

    imageLoader.DisplayImage(song.get(CustomizedListView.KEY_THUMB_URL), thumb_image);

    btn_add.setOnClickListener(new OnClickListener()
    {
        public void onClick(View v)
        {
           Intent intent = new Intent(Context, FinalOrder.class);
           startActivity(intent);
        }
    });

    return vi;

   }

protected void startActivity(Intent intent) {
    // TODO Auto-generated method stub

}

  }

在链接中提到的自定义适配器中，在getView方法中将单击列表器添加到图像按钮因此您可以处理自定义适配器中图像按钮的单击，如果您想在活动之间发送数据，您也可以在该单击列表器中发送它基于点击位置

myImageButton.setOnClickListener(new OnClickListener()
            {
                public void onClick(View v)
                {
Intent intent = new Intent(Context, nextactivity.class);
intent.putExtra("value",ValueArray[position]);
startActivity(intent);
})};

检查一下，如果这对你有帮助，请告诉我

您的适配器正在向您返回视图。正确的？

现在在你的 onitemclickListener

ImageButton myImageButton = (ImageButton) view.findViewById(R.id.addorder);

现在在您的 myImageButton 上应用 onclicklistener。
