BitmapFactory.Options options=new BitmapFactory.Options();
options.inJustDecodeBounds = false;
options.inSampleSize = 10; //width,hight设为原来的十分一
options.inJustDecodeBounds = false;
options.inSampleSize = 10; //width,hight设为原来的十分一
return BitmapFactory.decodeFile(imgPath,options);
options必加上
最后再回收
@Override
protected void onDestroy(){
if(b!=null){
b.recycle();
System.gc();
}
}
