我没有搜索，但无法找到在互联网上有用的答案。这就是为什么我提出查询。 我喜欢加载摄像头和捕捉图像中的自定义一个ArrayAdapter类的 getView 方法。摄像头是装和捕捉图像，但 onActivityResult（）永远不会被调用。我的code为如下图所示。

I did search but can't find useful answer in the internet. That is why I raise the query. I like to load the camera and capture image in the getView method of a custom ArrayAdapter class. Camera is loaded and capture image but onActivityResult() is never called. My code is as shown below.

       public View getView(int position, View convertView, ViewGroup parent) {
        View vi=convertView;
        ViewHolder viewHolder=new ViewHolder();
        LayoutInflater inflater = (LayoutInflater) this.getContext()
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        if(vi==null){
            vi = inflater.inflate(R.layout.list_row, parent, false);
            viewHolder.id=(TextView)vi.findViewById(R.id.title);
            viewHolder.thumbnailImage=(ImageView)vi.findViewById(R.id.list_image);
            viewHolder.arrow=(ImageView)vi.findViewById(R.id.list_arrow);
            vi.setTag(viewHolder);
        }
        else
            viewHolder=(ViewHolder) vi.getTag();



        // Setting all values in listview
        viewHolder.id.setText(listIDs.get(position));
        viewHolder.thumbnailImage.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                ((Activity)context).startActivityForResult(cameraIntent, CAMERA_REQUEST);
            }

        });
        return vi;
    }

   protected void onActivityResult(int requestCode, int resultCode, Intent data) { 

        if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {  
//            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
//            imageView.setImageBitmap(photo);
        }  

    } 

然后自定义适配器类是从 ListFragment 类激活为

customList_Adaptor adapter = new customList_Adaptor(
                getActivity(), R.layout.list_row, listIDs);

我要如何让onActivityResult（）方法被调用。 谢谢

How can I modify so that onActivityResult() method is called. Thanks

推荐答案

onActivityResult 属于活动。您可以在 Actvity / ListActivity 情况下只覆盖。你可以做的就是保持一个引用 Actvity / ListActivity 在你ArrayAdapter的子类，创建一个方法里面调用时 onActivityResult 被激发和条件都满足

onActivityResult belongs to the Activity. You can override only in the Actvity/ListActivity context. What you can do is to keep a reference to your ArrayAdapter's subclass inside the Actvity/ListActivity, create a method inside it to invoke when onActivityResult is fired and condition are met
