Android GridView

當GridView和SrollView嵌套使用時，GridView的高度就會產生問題，能夠經過繼承GridView，重寫

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) 方法，如

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int expandSpec = MeasureSpec.makeMeasureSpec(
                Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
}
