阅读以下教程： 您可以尝试以下代码 将宽度设置为版面宽度或屏幕宽度 查找屏幕宽度：
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int width = displaymetrics.widthPixels;
Drawable drawable = new BitmapDrawable(getResources(), decodeFile(chkFile, width , height ));
imageView.setBackground(drawable);
public Bitmap decodeFile(File f,int WIDTH,int HIGHT){
try {
//Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(f),null,o);
//The new size we want to scale to
final int REQUIRED_WIDTH=WIDTH;
final int REQUIRED_HIGHT=HIGHT;
//Find the correct scale value. It should be the power of 2.
int scale=1;
while(o.outWidth/scale/2>=REQUIRED_WIDTH && o.outHeight/scale/2>=REQUIRED_HIGHT)
scale*=2;
//Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize=scale;
return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
} catch (FileNotFoundException e) {
System.out.println("bitmap decodeFile:"+e);
}
return null;
}

谢谢。服务器正在向您发送一个base 64字符串，您正在尝试直接读取它的字节。首先需要对其进行解码，然后将其转换为字节数组 试试这个：
byte[] decodedBytes = Base64.decode(pic, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(decodedBytes ,0,decodedBytes.length)
如果有人知道。。。我在服务器上成功地将图像设置为base 64字符串，但在另一个类中检索该图像以设置图像视图“内存不足”OCCRUS:-（可能重复，在转换Base64I已调整大小的位图之前，您必须调整位图的大小..作为位图bm=BitmapFactory.decodeStream（fis）；ByteArrayOutputStream=new ByteArrayOutputStream（）；bm.compress（CompressFormat.JPEG，40，stream）；字符串imgString=Base64.encodeToString（stream.toByteArray（），Base64.NO_WRAP）；bm.recycle（）；[47,57,106,47,52,65,65,81,83,107,90,74,82,103,65,66,65,81,65,65,65,81,65,66,65,65,68,47,50,119]这是我检索的字节数组，我把它作为base64字符串放在远程数据库中..为什么我检索的数组太小..我认为在重新调整大小后，以及在从数据库检索相同图像后，存在一些问题，然后在图像视图上设置时显示错误
byte[] decodedBytes = Base64.decode(pic, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(decodedBytes ,0,decodedBytes.length)
