android – 无法在PopupWindow中为GridView执行OnItemClick

我有一个gridView,我在弹出窗口中显示(gridview是透明布局,继承自linearlayout,只有一个部分透明的背景).我永远无法让这个GridView的OnItemClick执行.当我触摸gridview中的图像时,它似乎被点击(图像BAChgrond更改),但OnItemClick未被调用.

下面是我的适配器的代码和包含gridView的弹出视图.谢谢！

//Adapter

公共类ImageAdapter扩展BaseAdapter {
    private Context mContext;
    privatE int itemBACkground;

public ImageAdapter(Context C) {
    mContext = c;

  //---setTing the style---
    TypedArray a = c.obtainStyledAttributes(R.styleable.Gallery1);
    itemBACkground = a.getresourcEID(R.styleable.Gallery1_android_galleryItemBACkground,0);
    a.recycle();
}

public View getView(int position,View convertView,ViewGroup parent) {
    ImageView imageView;
    if (convertView == null) {
        imageView = new ImageView(mContext);
    } else {
        imageView = (ImageView) convertView;
    }
    imageView.setImageresource(images[position]);
    imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
    imageView.setBACkgroundresource(itemBACkground);
    return imageView;

}
public Integer[] images = {
        R.drawable.sound1,R.drawable.sound2,R.drawable.sound3,R.drawable.sound4
};
