从android中的服务器加载多个图像给VM Buget内存不足

Question

我使用的是懒惰加载程序示例，但我的应用程序在Logcat中给出了以下错误。

12-14 15:27:55.987: E/dalvikvm-heap(27566): 2457600-byte external allocation too large for this process.
12-14 15:27:55.992: E/(27566): VM won't let us allocate 2457600 bytes
12-14 15:27:55.992: D/skia(27566): --- decoder->decode returned false

我在写时使用Imageloader类

  private Bitmap decodeFile(File f){
            try {
                //decode image size
                BitmapFactory.Options o = new BitmapFactory.Options();
                o.inJustDecodeBounds = true;
                o.inPurgeable = true; // Tell to garbage collector that whether it needs free memory, the Bitmap can be cleared
                o.inTempStorage = new byte[32 * 1024];
                BitmapFactory.decodeStream(new FileInputStream(f),null,o);
                //Find the correct scale value. It should be the power of 2.
                final int REQUIRED_SIZE=70;
                int width_tmp=o.outWidth, height_tmp=o.outHeight;
                int scale=1;
                while(true){
                    if(width_tmp/2<REQUIRED_SIZE || height_tmp/2<REQUIRED_SIZE)
                        break;
                    width_tmp/=2;
                    height_tmp/=2;

                      scale*=2; 

                }
                //decode with inSampleSize
                BitmapFactory.Options o2 = new BitmapFactory.Options();
                o2.inPurgeable = true; // Tell to garbage collector that whether it needs free memory, the Bitmap can be cleared
                o2.inTempStorage = new byte[32 * 1024];
                o2.inSampleSize=scale;
                Bitmap bitmap1=BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
              //  System.out.println("width : "+bitmap1.getWidth()+ " height : "+bitmap1.getHeight());
           /*     if(bitmap1.getHeight()>=bitmap1.getWidth())
                {
                    bitmap1 = Bitmap.createScaledBitmap(bitmap1, bitmap1.getHeight(),bitmap1.getWidth(), true);
                }else{
                    //bmp = Bitmap.createScaledBitmap(bmp, (int) height2,width, true);
                    Matrix matrix = new Matrix();
                    matrix.postRotate(270);
                    bitmap1 = Bitmap.createBitmap(bitmap1 , 0, 0, bitmap1 .getWidth(), bitmap1 .getHeight(), matrix, true);
                }*/
                return bitmap1;
            } catch (FileNotFoundException e) {}
            return null;
        }

但我使用sacle=scale*1，因为我想要使用scale-scale*2的高清图像，然后我的图像像模糊一样。。

那我该怎么办？

Answer 1

我建议您使用Picasso库。它比Android通用图像加载器更简单，但功能同样强大。

Answer 2

您不需要做所有这些。试试这个图书馆。这太棒了。Android通用图像加载器
