android在GridView中显示图像选择

Question

我在android中开发了一种图库应用程序，我希望显示从GridView.中选择的图像

我从设备的SD卡获取图像，我使用CustomAdapter来选择图像。

这是我的CustomGridAdapter.java

private class CustomGridAdapter extends BaseAdapter {
    String[] items;
    MainActivity context;
    LayoutInflater inflater;

    public CustomGridAdapter(MainActivity context, String[] items) {
        this.context = context;
        this.items = items;
        inflater = (LayoutInflater) this.context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return items.length;
    }

    @Override
    public Object getItem(int position) {
        return items[position];
    }

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

    @Override
    public View getView(final int position, View convertView,
                        ViewGroup parent) {
        if (convertView == null) {
            convertView = inflater.inflate(R.layout.cell, null);
        }

        final ImageView img = (ImageView) convertView.findViewById(R.id.img);
        Bitmap bmp = BitmapFactory.decodeFile(path + "/" + items[position] + "/off.png");
        img.setImageBitmap(bmp);
        img.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                context.itemClicked(position);
            }
        });
        return convertView;
    }
}

有人可以帮忙吗？
