額外的空間雖然向ScrollView添加網格視圖

Question

我使用的GridView裏面scrollview（我知道不好的做法，但要求是這樣的）。問題在於它們是GridView結尾處不需要的額外垂直空間。我也通過這個代碼動態地設置GridView的高度。 coulmns的

public static void setHeightDynamically(GridView listView) { 
     ListAdapter listAdapter = listView.getAdapter(); 
     if (listAdapter == null) 
      return; 

     int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.UNSPECIFIED); 
     int totalHeight = 0; 
     View view = null; 
     for (int i = 0; i < listAdapter.getCount(); i++) { 
      view = listAdapter.getView(i, view, listView); 
      view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED); 
      totalHeight += view.getMeasuredHeight(); 
     } 
     ViewGroup.LayoutParams params = listView.getLayoutParams(); 
     params.height = totalHeight; 
     listView.setLayoutParams(params); 
     listView.requestLayout(); 
    } 

我的XML是這樣的

<RelativeLayout 
    android:id="@+id/container" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <include 
     android:id="@+id/header_section" 
     layout="@layout/header_screen" /> 


    <ScrollView 
     android:id="@+id/parent_scroll" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:background="@android:color/white" 
     android:layout_alignWithParentIfMissing="false" 

     android:layout_below="@+id/header_section"> 

     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:orientation="vertical"> 


       <FrameLayout 
        android:id="@+id/frame" 
        android:layout_width="match_parent" 
        android:layout_height="200dp" /> 





      <ListView 
       android:id="@+id/list" 
       android:layout_width="match_parent"

       ></ListView> 

      <TextView

      <View 
       android:layout_width="match_parent" 
       android:layout_height="1dp" 
       android:background="@android:color/darker_gray" /> 

      <RelativeLayout 
       android:id="@+id/layout" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content"

       <TextView

       <ImageView 
        android:id="@+id/icon" 
        android:layout_width="50dp" 
        android:layout_height="50dp" 
        android:layout_below="@+id/txt" 
        android:scaleType="fitXY" 
        android:layout_margin="5dp" 
        /> 

       <TextView

        android:textColor="@android:color/black" 
        android:textSize="12sp" /> 
      </RelativeLayout> 

      <View 
       android:layout_width="match_parent" 
       android:layout_height="1dp"

       <GridView

     </LinearLayout> 
    </ScrollView> 
</RelativeLayout> 

<include layout="@layout/nav_drawer" />

製作增量根據列在網格視圖的數量，在這裏我假設數量2所以只需在你的循環中增加+2點

public static void setHeightDynamically(GridView listView) { 
     ListAdapter listAdapter = listView.getAdapter(); 
     if (listAdapter == null) 
      return; 

     int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.UNSPECIFIED); 
     int totalHeight = 0; 
     View view = null; 
     for (int i = 0; i < listAdapter.getCount(); i = i+2) { 
      view = listAdapter.getView(i, view, listView); 
      view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED); 
      totalHeight += view.getMeasuredHeight(); 
     } 
     ViewGroup.LayoutParams params = listView.getLayoutParams(); 
     params.height = totalHeight; 
     listView.setLayoutParams(params); 
     listView.requestLayout(); 
    }
