I 4 - colums grid where the items are an image on top and bellow a
textview. The image fills all the available width - no padding or anything.
My images will all have exactly the same size.
Now I want that the height of the view adjusts to the width - to keep the
images proportional. AFAIK this is not possible with Android's scaling
types. So I put this code after I load the bitmap (it's feched from the
web):
imageView.post(new Runnable() {
@Override
public void run() {
double factor = loadedBitmap.getWidth() /
(loadedBitmap.getHeight());
int width = imageView.getWidth();
int newH = (int)(width * factor);
LinearLayout.LayoutParams params = new
LinearLayout.LayoutParams(width, newH);
imageView.setLayoutParams(params);
//convertViewFinal.invalidate(); //doesn't help
//convertViewFinal.requestLayout(); //doesn't help
}
});
It works for most of the images, but on some, it doesn't show any image
(the imageview looks like GONE), and in some cases this also breaks the
grid layout. Why is it? I know that the bitmaps are fine, because, in my
testing application, I loop through the same bitmaps many times - they
appear after x items in the grid again, and they are fine. And each time I
load the grid, different items have the problem.
