Hi Ken,
It seems that the grid does not behave well if WRAP_LAYOUT or FILL_PARENT
are used inside the cell's layout.
I changed the following code :
addView(icon, new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
this.icon.setImageBitmap(getBitmap(urlString));
this.name = new TextView(context);
addView(this.name, new
LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
to:
addView(icon, new
LinearLayout.LayoutParams(50,50));
this.icon.setImageBitmap(getBitmap(urlString));
this.name = new TextView(context);
addView(this.name, new
LinearLayout.LayoutParams(50,50));
and then your grid works fine. You may want to log a bug in the issue
tracker about the grid getting distorted by using the WRAP_LAYOUT and
FILL_LAYOUT.
Thanks,
Megha
