I have a GridView with ImageViews inside. I have 3 of them for each row. I can set correctly the width with WRAP_CONTENT and scaleType = CENTER_CROP, but I don't know how to set the ImageView's size to be a square. Here's what I did until now, it seems to be ok except the height, that is "static":
imageView = new ImageView(context);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setLayoutParams(new GridView.LayoutParams(GridView.LayoutParams.WRAP_CONTENT, 300));
I'm doing it inside an adapter.
The best option is to subclass ImageView
yourself, overriding the measure pass:
public class SquareImageView extends ImageView {
...
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int width = getMeasuredWidth();
setMeasuredDimension(width, width);
}
...
}
