android - 如何在android中的scrollView中添加gridView

Question

在该问题被投票为可能与 this 重复之前, this或this我有一个 Material 设计抽屉导航。在主要 Activity 中，我有以下元素，如图像 A 和 B 所示。我想添加 ScrollView 功能，以便滚动项目将使用户能够滚动包括 gridView 在内的整个布局，如下所示在图像 A 中看到。但是，在包含 ScrollView 时，我在 B 中遇到了问题，其中仅显示一行。我在 google 和 S/O 上进行了研究，但解决方案不起作用。解决方案没有<android.support.v4.widget.DrawerLayout作为父 View ，这样您就可以想象我是多么卡住。任何解决方案或解决方法都将受到赞赏。

也许您需要这个自定义 gridView。

公共(public)类 InnerGridView 扩展 GridView {

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

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

public InnerGridView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    // Max Height
    int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
            MeasureSpec.AT_MOST);


    super.onMeasure(widthMeasureSpec, expandSpec);
}

}
