单击GridView项目时在PopupWindow中显示完整图像？

我想显示一个弹出窗口，显示我刚刚在GridView中单击的全屏图像。单击GridView项目时在PopupWindow中显示完整图像？

movieBrowser.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View v, int position, long id) { 
     LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE); 
     View popupView = layoutInflater.inflate(R.layout.popup, null); 
     final PopupWindow popupWindow = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 
     popupWindow.showAtLocation(parent, Gravity.CENTER_VERTICAL); 
     ImageView fullImageView = (ImageView) findViewById(R.id.full_image); 
     fullImageView.setImageResource(mThumbIds[position]); 
    } 
});

这里是图像适配器

public class ImageAdapter extends BaseAdapter { 
    private Context mContext; 
    public ImageAdapter(Context c) { 
     mContext = c; 
    } 
    public int getCount() { 
     return mThumbIds.length; 
    } 
    public Object getItem(int position) { 
     return null; 
    } 
    public long getItemId(int position) { 
     return 0; 
    } 
    public View getView(int position, View convertView, ViewGroup parent) { 
     ImageView imageView; 
     if (convertView == null) { 
      imageView = new ImageView(mContext); 
      imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); 
      imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
      imageView.setPadding(8, 8, 8, 8); 
     } else { 
      imageView = (ImageView) convertView; 
     } 
     imageView.setImageResource(mThumbIds[position]); 
     return imageView; 
    } 

    private Integer[] mThumbIds = { 
      R.drawable.sample_2, R.drawable.sample_3, 
      R.drawable.sample_4, R.drawable.sample_5, 
      R.drawable.sample_6, R.drawable.sample_7, 
      R.drawable.sample_0, R.drawable.sample_1, 
      R.drawable.sample_2, R.drawable.sample_3, 
      R.drawable.sample_4, R.drawable.sample_5, 
      R.drawable.sample_6, R.drawable.sample_7, 
      R.drawable.sample_0, R.drawable.sample_1, 
      R.drawable.sample_2, R.drawable.sample_3, 
      R.drawable.sample_4, R.drawable.sample_5, 
      R.drawable.sample_6, R.drawable.sample_7 
    }; 

    } 
}

什么问题？你的代码的结果是什么，它与你想实现的有什么不同？ – Ridcully

此代码无法运行fullImageView.setImageResource（mThumbsIds [positon]给出错误，我想要的是获取图像在GridView中的位置并将其传递给ImageView中的弹出布局，因此弹出完整图像。 – homi3kh

你应该编辑你的问题并在那里陈述这个问题，并且还会出现什么错误（最好添加LogCat消息的相关部分）如果你想让这里的人帮助你，你必须提供所有可能相关的东西。知道你的代码，没有人知道错误，没有人知道你想要达到什么，什么不工作，如果你没有尽可能清楚地告诉我们。 – Ridcully

尝试改变：

ImageView fullImageView = (ImageView) findViewById(R.id.full_image);

要：

ImageView fullImageView = (ImageView) popupView.findViewById(R.id.full_image);
