| convertView | The old view to reuse, if possible. Note: You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view.

//原QVGA 2.7吋螢幕解析度為240 * 320
if(metrics.heightPixels > 320)
{
//改變editText1的高度
editText1.getLayoutParams().height = 600;
}
}
