Recycle ImageView's Bitmap

Question

I have something like this:

Bitmap.Config conf = Bitmap.Config.ARGB_8888;
WeakReference bm = new WeakReference(Bitmap.createBitma         


        

Answer 1

If you set the same bitmap object on all your ImageViews, it shouldn't throw an OutOfMemoryError. Basically, this should work:

WeakReference bm = new WeakReference(Bitmap.createBitmap(3000 + 3000, 2000, Bitmap.Config.ARGB_8888));

Canvas canvas = new Canvas(bm.get());
canvas.drawBitmap(firstBitmap, 0, 0, null);
canvas.drawBitmap(bm, firstBitmap.getWidth(), 0, null);

imageView1.setImageBitmap(bm.get());
imageView2.setImageBitmap(bm.get());
imageView3.setImageBitmap(bm.get());
imageView4.setImageBitmap(bm.get());
imageView5.setImageBitmap(bm.get());
// ...

If this doesn't work, it simply means your bitmap is too large (6000x2000 pixels is about 12 megabytes, if I calculated right). You can either:

• make your bitmap smaller
• cut down on other stuff that use a lot of memory
