gallery每屏僅顯示一幅圖片

 

   public View getView(int position, View convertView, ViewGroup parent) {
        ImageView p_w_picpathView = new ImageView(context);
        Bitmap bitmap = this.p_w_picpaths.get(position);
        p_w_picpathView.setImageBitmap(bitmap);
        //設置樣式 ：填充整個屏幕
        p_w_picpathView.setLayoutParams(new Gallery.LayoutParams(Gallery.LayoutParams.FILL_PARENT,
                Gallery.LayoutParams.FILL_PARENT));
        //設置縮放比例：保持原樣
        p_w_picpathView.setScaleType(ImageView.ScaleType.CENTER);
        return p_w_picpathView;
    }
