ScrollView中只能放一个控件，一般都放LinearLayout，orientation属性值为vertical。在LinearLayout中放需要呈现的内容。ListView也在其中，ListView的高度设为适应自身内容（wrap_content）。但是为啥在scrollview中嵌套listview会出现只显示第一条listitem的高度呢，原因是：scrollview的ontach方法的滚动事件消费处理，ListView控件的高度设定问题
从谷歌那里找到的ScrollView嵌套ListView只显示一行的解决办法相信很多人都遇到过，然后大部分都是用这位博主的办法解决的吧
刚开始我也是用这个办法解决的，首先感谢这位哥的大私奉献，贴上地址

2、解决的核心代码
public void setListViewHeightBasedOnChildren(ListView listView) { // 获取ListView对应的Adapter ListAdapter listAdapter = listView.getAdapter(); if (listAdapter == null) { return; } int totalHeight = 0; for (int i = 0, len = listAdapter.getCount(); i < len; i++) { // listAdapter.getCount()返回数据项的数目 View listItem = listAdapter.getView(i, null, listView); // 计算子项View 的宽高 listItem.measure(0, 0); // 统计所有子项的总高度 totalHeight += listItem.getMeasuredHeight(); } ViewGroup.LayoutParams params = listView.getLayoutParams(); params.height = totalHeight+ (listView.getDividerHeight() * (listAdapter.getCount() - 1)); // listView.getDividerHeight()获取子项间分隔符占用的高度 // params.height最后得到整个ListView完整显示需要的高度 listView.setLayoutParams(params); } 这个代码让控件去计算Listview自己的高度然后设置这个Listview的高度
但是这个代码里面有一个问题，就是这个当你的ListView里面有多行的TextView的话，ListView的高度就会计算错误，它只算到了一行TextView的高度，

3、终极解决办法
这个问题头疼了一阵后，查找了一下，应该重写一个TextView的onMeasure方法比较好解决
代码有
@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); Layout layout = getLayout(); if (layout != null) { int height = (int)FloatMath.ceil(getMaxLineHeight(this.getText().toString())) + getCompoundPaddingTop() + getCompoundPaddingBottom(); int width = getMeasuredWidth(); setMeasuredDimension(width, height); } } private float getMaxLineHeight(String str) { float height = 0.0f; float screenW = ((Activity)context).getWindowManager().getDefaultDisplay().getWidth(); float paddingLeft = ((LinearLayout)this.getParent()).getPaddingLeft(); float paddingReft = ((LinearLayout)this.getParent()).getPaddingRight(); //这里具体this.getPaint()要注意使用，要看你的TextView在什么位置，这个是拿TextView父控件的Padding的，为了更准确的算出换行 int line = (int) Math.ceil( (this.getPaint().measureText(str)/(screenW-paddingLeft-paddingReft))); height = (this.getPaint().getFontMetrics().descent-this.getPaint().getFontMetrics().ascent)*line; return height;}
上面的代码完成更能为，在ListView开始测量时，测量到TextView时，就调用我们的onMeasure方法，我们就可以测量字体的总宽度除与去掉边距的屏幕的大小，就可以算出文字要几行来显示，然后测量字体的高度*行数可以得到字体的总高度，然后在加上上下边距就是TextView真正的高度，然后setMeasuredDimension进去就可以计算出正确的值出来。
完整大代码我贴出来
public class MyListView2 extends LinearLayout {private BaseAdapter adapter;private MyOnItemClickListener onItemClickListener;boolean footerViewAttached = false;private View footerview;@Overrideprotected void onLayout(boolean changed, int l, int t, int r, int b) {// TODO Auto-generated method stubsuper.onLayout(changed, l, t, r, b);}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);super.onMeasure(widthMeasureSpec, expandSpec);}public void notifyChange() {int count = getChildCount();if (footerViewAttached) {count--;}LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);for (int i = count; i < adapter.getCount(); i++) {final int index = i;final LinearLayout layout = new LinearLayout(getContext());layout.setLayoutParams(params);layout.setOrientation(VERTICAL);View v = adapter.getView(i, null, null);v.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {if (onItemClickListener != null) {onItemClickListener.onItemClick(MyListView2.this,layout, index, adapter.getItem(index));}}});ImageView imageView = new ImageView(getContext());imageView.setLayoutParams(params);layout.addView(v);layout.addView(imageView);addView(layout, index);}}public MyListView2(Context context) {super(context);initAttr(null);}public MyListView2(Context context, AttributeSet attrs) {super(context, attrs);initAttr(attrs);}public void initAttr(AttributeSet attrs) {setOrientation(VERTICAL);}public void initFooterView(final View footerView) {this.footerview = footerView;}public void setFooterViewListener(OnClickListener onClickListener) {this.footerview.setOnClickListener(onClickListener);}public BaseAdapter getAdapter() {return adapter;}public void setAdapter(BaseAdapter adpater) {this.adapter = adpater;removeAllViews();if (footerViewAttached)addView(footerview);notifyChange();}public void setOnItemClickListener(MyOnItemClickListener onClickListener) {this.onItemClickListener = onClickListener;}public void noMorePages() {if (footerview != null && footerViewAttached) {removeView(footerview);footerViewAttached = false;}}public void mayHaveMorePages() {if (!footerViewAttached && footerview != null) {addView(footerview);footerViewAttached = true;}}public static interface MyOnItemClickListener {public void onItemClick(ViewGroup parent, View view, int position,Object o);} }
这个adapter就是你获取数据后设置的，也就是上面两点的综合
