在将问题投票为thisthisthis的可能副本之前我有一个材质设计导航抽屉。在主要活动中,我具有以下元素,如从图像A和B.我想添加一个滚动视图功能,以便滚动项目将使用户滚动包含gridView的整个布局,如图A所示。但是,在包含滚动视图时,我会在B中显示只有一行显示的问题。我研究谷歌和S/O和解决方案没有奏效。该解决方案没有<android.support.v4.widget.DrawerLayout作为父视图,因此您可以了解我的困惑程度。任何解决方案或解决方法都将被优先考虑。 enter image description here如何在android中的scrollView中添加gridView android

我想我可能会添加此为别人谁来寻找。经过实施@innershows答案一个完整的答案,我创建的类InnerGridView InnerGridView gridView = (InnerGridView) findViewById(R.id.grid); adapter = new CustomListAdapter(this, movieList); gridView.setAdapter(adapter); 然后在我的activty_main:

也许你甲肾上腺素编辑这个自定义的gridView。

公共类InnerGridView扩展的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); 
}

然后我添加自定义gridview来替换我的网格视图? – 2015-03-13 09:16:29
