注：本文是由网上大神分享的解决方案汇集而成

方法一：

重写ListView、GridView：

重写ListView：

public class MyListView extends ListView {

public MyListView(Context context) {
// TODO Auto-generated method stub
super(context);
}

public MyListView(Context context, AttributeSet attrs) {
// TODO Auto-generated method stub
super(context, attrs);
}

public MyListView(Context context, AttributeSet attrs, int defStyle) {
// TODO Auto-generated method stub
super(context, attrs, defStyle);
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
// TODO Auto-generated method stub
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
} 重写GridView：

/**

* @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" /> 此方案亲测有效。

方法二：通过计算出来ListView或者GridView中的子列高度和 进行显示：

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，本人未测试！！
