android ScrollView中嵌套GridView，ListView只顯示一行的解決辦法

註：本文是由網上大神分享的解決方案彙集而成

方法一：

重寫ListView、GridView：

重寫ListView：

public class MyListView extends ListView {public MyListView(Context context) {// TODO Auto-generated method stubsuper(context);}public MyListView(Context context, AttributeSet attrs) {// TODO Auto-generated method stubsuper(context, attrs);}public MyListView(Context context, AttributeSet attrs, int defStyle) {// TODO Auto-generated method stubsuper(context, attrs, defStyle);}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {// TODO Auto-generated method stubint expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);super.onMeasure(widthMeasureSpec, expandSpec);}}

重寫GridView：

/** * 自訂gridview，解決ListView中嵌套gridview顯示不正常的問題（1行半） * @author wangyx * @version 1.0.0 2012-9-14 */public class MyGridView extends GridView{  public MyGridView(Context context, AttributeSet attrs) {         super(context, attrs);     }      public MyGridView(Context context) {         super(context);     }      public MyGridView(Context context, AttributeSet attrs, int defStyle) {         super(context, attrs, defStyle);     }      @Override     public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {          int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,                 MeasureSpec.AT_MOST);         super.onMeasure(widthMeasureSpec, expandSpec);     } }

xml中的布局：

<com.xxx.MyGridView              android:id="@+id/mygridview"              android:layout_width="fill_parent"              android:layout_height="wrap_content"              android:gravity="center"              android:horizontalSpacing="5dp"              android:numColumns="4"              android:stretchMode="columnWidth"              android:verticalSpacing="6dp" /> 

此方案親測有效。

方法二：通過計算出來ListView或者GridView中的子列高度和 進行顯示：

public void setListViewHeightBasedOnChildren(ListView listView) {      ListAdapter listAdapter = listView.getAdapter();       if (listAdapter == null) {          return;      }      int totalHeight = 0;      for (int i = 0; i < listAdapter.getCount(); i++) {          View listItem = listAdapter.getView(i, null, listView);          listItem.measure(0, 0);          totalHeight += listItem.getMeasuredHeight();      }      ViewGroup.LayoutParams params = listView.getLayoutParams();      params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));      ((MarginLayoutParams)params).setMargins(10, 10, 10, 10);    listView.setLayoutParams(params);  } 

此方案，測試過同樣可以達到效果
