用于简单自定义gridview控件

public mylist(Context context) {
super(context);
}

public mylist(Context context, AttributeSet attrs) {
super(context, attrs);
}

public mylist(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int h = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, h);
}
