我是安卓新手。我正在做 sd-card 的图像列表表格。以下代码给我错误“614416 字节分配上的内存不足”。
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.ll_sponsor_list_item,
parent, false);
final ImageView img = (ImageView) convertView
.findViewById(R.id.imggrid_item_image);
String imgurl = ImageName.get(position);
AsyncImageLoaderv asyncImageLoaderv = new AsyncImageLoaderv();
Bitmap cachedImage = asyncImageLoaderv.loadDrawable(imgurl,
new AsyncImageLoaderv.ImageCallback() {
public void imageLoaded(Bitmap imageDrawable,
String imageUrl) {
img.setImageBitmap(imageDrawable);
}
});
img.setImageBitmap(cachedImage);
cachedImage.recycle();
return convertView;
}
班级：
class AsyncImageLoaderv {
int width;
int height;
float aspectRatio;
int newWidth;
int newHeight;
public Bitmap loadDrawable(final String imageUrl,
final ImageCallback imageCallback) {
final Handler handler = new Handler() {
@Override
public void handleMessage(Message message) {
imageCallback.imageLoaded((Bitmap) message.obj, imageUrl);
}
};
new Thread() {
@Override
public void run() {
try {
Log.d("ur", imageUrl);
Bitmap drawable = BitmapFactory.decodeFile(imageUrl);
width = drawable.getWidth();
height = drawable.getWidth();
aspectRatio = (float) width / (float) height;
newWidth = 98;
newHeight = (int) (98 / aspectRatio);
Bitmap.createScaledBitmap(drawable, newWidth, newHeight,
true);
Message message = handler.obtainMessage(0, drawable);
handler.sendMessage(message);
//this.sleep(1000);
} catch (Exception e) {
Log.e("thread stellent", e.toString());
}
}
}.start();
return null;
}
public interface ImageCallback {
public void imageLoaded(Bitmap imageBitmap, String imageUrl);
