RelativeLayout Cast error with alcatel tablet on android
<p>This is my code:</p>

<pre><code>                WindowManager wm = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE);
                Display display = wm.getDefaultDisplay();
                Point size = new Point();
                display.getSize(size);
                int height = size.x / 3;
                RelativeLayout.LayoutParams mParams = (RelativeLayout.LayoutParams) gridview.getLayoutParams();
                int rows = (int) Math.ceil(mAreas.size()/3.0);
                mParams.height = rows * height;
                gridview.setLayoutParams(mParams);
</code></pre>

<p>Its working fine in any device, but i tried it on a alcatel tablet and for some reason i am getting this error, any suggestion?, it looks like alcatel changed the class for some odd reason and stopped working like the rest of the android distributions?</p>
