我需要显示可绘制文件夹中的图像。我创建了一个整数数组来存储可绘制的ID,就像这样
private int[] itemImages = new int[]{
R.drawable.image1, R.drawable.image2, R.drawable.image3,
R.drawable.image4, R.drawable.image5, R.drawable.image6,
R.drawable.image7, R.drawable.image8, R.drawable.image9,
R.drawable.image10, R.drawable.image11, R.drawable.image12,
R.drawable.image13, R.drawable.image14, R.drawable.image15,
R.drawable.image16, R.drawable.image7, R.drawable.image18,
R.drawable.image19, R.drawable.image20, R.drawable.image21,
R.drawable.image22, R.drawable.image23, R.drawable.image24,
R.drawable.image25, R.drawable.image26, R.drawable.image27
};
和其他一些文本itemPrice
和itemNames
然后创建一个列表,并将元素传递给自定义数组适配器
List<HashMap<String, String>> imageArray = new ArrayList<HashMap<String, String>>();
for (int i = 0; i < itemImages.length; i++) {
HashMap<String, String> hm = new HashMap<String, String>();
hm.put("name", "Name : " + itemNames[i]);
hm.put("price", "Price : " + itemPrices[i]);
hm.put("image", Integer.toString(itemImages[i]));
imageArray.add(hm);
}
Custom_Adapter adapter = new Custom_Adapter(getApplicationContext(),
R.layout.imagelist_layout, imageArray);
定制数组适配器中的getView是
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View displeyView = inflater.inflate(R.layout.imagelist_layout, parent, false);
ImageView img = (ImageView) displeyView.findViewById(R.id.image);
TextView name = (TextView) displeyView.findViewById(R.id.name);
TextView price = (TextView) displeyView.findViewById(R.id.price);
try {
final HashMap<String, String> imgList = imageList.get(position);
final String image = imgList.get("image");
final String price1 = imgList.get("price");
final String name1 = imgList.get("name");
imageLoader.displayImage(image, img, options);
name.setText(name1);
price.setText(price1);
} catch (Exception e) {
}
return displeyView;
}
通过这样做,将显示文本。但我无法查看图像。显示R.drawable.errorimage。我该如何解决?
[如果您只是尝试将可绘制的图像设置为imageview的背景,则可以使用]进行设置>
imageView.setImageResource(yourDrawable);
但是我认为您有一些内存问题,或者需要使用Unviersal Image Loader的Display Options,例如四舍五入的位图下载。
您可以使用通用图像加载器设置可绘制:
String yourUrl = "drawable://" + R.drawable.your_drawable; com.nostra13.universalimageloader.core.ImageLoader.getInstance().displayImage(yourUrl, yourImageView, displayOptions);
我希望这会对您有所帮助。
[通用图像加载器可帮助您以良好的效果在Internet上加载图像,并以本地方法加载本地图像,而不是使用本机方法来加载可绘制对象– ImageView.setImageResource(...)代替使用ImageLoader很好,根据我的看法...
