如何在android中压缩imageview的图像

嗨我想在我的视图中显示存储在SD卡中的3或4个图像,图像的大小约为1-2 MB.
我的问题是当我在imageview中使用image然后它会抛出内存异常
我在将图像解码为位图时创建了位和传递选项

任何人都可以帮助我解决我的问题
提前致谢

解决方法:

我找到了我的问题的解决方案有我的代码：

BitmapFactory.Options options = new BitmapFactory.Options();
options.inTempStorage = new byte[24*1024];  
options.inJustDecodeBounds = false;
options.inSampleSize=32;     
bmp1=BitmapFactory.decodeFile(filepath1,options);  
Bitmap b1=ThumbnailUtils.extractThumbnail(bmp1,30, 30);  
iv1.setimageBitmap(b);  
 if(bmp1!=null){  
   bmp1.recycle();
   }  
         bmp1=BitmapFactory.decodeFile(filepath1,options);
 Bitmap b2=ThumbnailUtils.extractThumbnail(bmp1,30, 30);  
 iv2.setimageBitmap(b2);  
if(bmp1!=null){  
 bmp1.recycle();
 }

同样地,我将它用于四个图像视图并设置图像而没有OOM异常
