这是我的适配器类
public class ImageAdapter extends BaseAdapter {
Context mcontext;
Integer Imageid[] = new Integer[] { R.drawable.image1, R.drawable.image3,
R.drawable.image4, R.drawable.image5, R.drawable.image6,
R.drawable.image2 };
public ImageAdapter(Context context) {
// TODO Auto-generated constructor stub
super();
this.mcontext = context;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return Imageid.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflater = (LayoutInflater) mcontext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if(convertView == null){
gridView = new View(mcontext);
gridView = inflater.inflate(R.layout.imageview,null);
ImageView imageView =(ImageView)gridView.findViewById(R.id.imageView);
imageView.setImageResource(Imageid[position]);
}
else {
gridView = (View) convertView;
}
return gridView;
}
}
这是为什么错误？..
why is this error?..
在此先感谢：）
推荐答案
什么是发生在这里的是，,,,应用是走出去堆size.So你必须去code中的图像以这样的方式它会掉下堆下size.Do这个code在适配器
What is Happening here is that,,, the app is going out of heap size.So you have to decode the image in such a way that it will fall under the heap size.Do this code in your adapter
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater inflater = (LayoutInflater) mcontext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView;
if(convertView == null){
gridView = new View(mcontext);
gridView = inflater.inflate(R.layout.imageview,null);
ImageView imageView =(ImageView)gridView.findViewById(R.id.imageView);
BitmapFactory.Options options = new BitmapFactory.Options();
options.inDither = false;
options.inJustDecodeBounds = false;
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
options.inSampleSize = 3;
options.inPurgeable = true;
Bitmap icon = BitmapFactory.decodeResource(context.getResources(),
Imageid[position],options);
holder.imageView.setImageBitmap(icon);
}
else {
gridView = (View) convertView;
}
return gridView;
}
