位图和相机

Question

我没有解决这个错误成功：

java.lang.OutOfMemoryError: bitmap size exceeds VM budget.

我的代码是：

BitmapFactory.Options op = new BitmapFactory.Options(); 
myBitmap = BitmapFactory.decodeFile(file.getAbsolutePath(),op); 
ImageView _image = (ImageView)view.findViewById(R.id.imageCarte); 

int width = myBitmap.getWidth(); 
int height = myBitmap.getHeight(); 
int halfWidth = width/2; 
int halfHeight = height/2; 
Bitmap bmHalf = Bitmap.createScaledBitmap(myBitmap, halfWidth, halfHeight, false); 
_image.setImageBitmap(bmHalf); 

Answer 1

This是一个必须阅读在Android中处理位图。

Answer 2

您可以在BitmapFactory.Options实例指定inSampleSize：

If set to a value > 1, requests the decoder to subsample the original image, returning a smaller image to save memory.

例如：

BitmapFactory.Options op = new BitmapFactory.Options(); 
op.inSampleSize = 2 
myBitmap = BitmapFactory.decodeFile(file.getAbsolutePath(),op); 
ImageView _image = (ImageView)view.findViewById(R.id.imageCarte); 
_image.setImageBitmap(myBitmap);
