android scrollview listview显示不全

原来处理方法是重写ListView

import android.content.Context;

import android.util.AttributeSet;

import android.view.MotionEvent;

import android.widget.ListView;



public class MyListView extends ListView {



    public MyListView(Context context) {

        super(context);

        // TODO Auto-generated constructor stub

    }

    public MyListView(Context context, AttributeSet attrs) {  

        super(context, attrs);  

    }  

  

    public MyListView(Context context, AttributeSet attrs, int defStyle) {  

        super(context, attrs, defStyle);  

    }  

  

    @Override  

    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {  

        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);  

        super.onMeasure(widthMeasureSpec, expandSpec);  

    }  

  

    @Override  

    public boolean dispatchTouchEvent(MotionEvent ev) {  

        if(ev.getAction() == MotionEvent.ACTION_MOVE){     

            return true;   

        }   

        return super.dispatchTouchEvent(ev);  

    }  

}

试了这种方法还是显示不全 总是少二项内容

又使用了

public static 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);

            listItem.measure(0, 0); // 计算子项View 的宽高

            totalHeight += listItem.getMeasuredHeight(); // 统计所有子项的总高度

        }



        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);

    }

View Code

还是一样效果 少二项内容

最后在网上找到有人重写LinearLayout显示列表

import android.content.Context;

import android.util.AttributeSet;

import android.util.Log;

import android.util.TypedValue;

import android.view.View;

import android.widget.AdapterView.OnItemClickListener;

import android.widget.BaseAdapter;

import android.widget.LinearLayout;







/***

public class LinearLayoutForListView extends LinearLayout

{

    private BaseAdapter adapter;

    private OnItemClickListener onItemClickListener;



    

    /**

     * 通过 Java代码  实例化

     * @param context

     */

    public LinearLayoutForListView(Context context)

    {

        super(context);

        //设置LinearLayoutForListView为垂直布局，否者默认为水平布局，容易疏忽导致子项显示不全

        LinearLayoutForListView.this.setOrientation(LinearLayout.VERTICAL);

    }



    

    /**

     * 此构造函数可以允许我们通过 XML的方式注册 控件

     * @param context

     * @param attrs

     */

    public LinearLayoutForListView(Context context, AttributeSet attrs)

    {

        super(context, attrs);

        LinearLayoutForListView.this.setOrientation(LinearLayout.VERTICAL);

    }

    

    



    /**

     */

    public void setAdapter(BaseAdapter adpater)

    {

        this.adapter = adpater;

        bindLinearLayout();

    }



    /**

     * 

     * @return adapter

     */

    public BaseAdapter getAdpater()

    {

        return adapter;

    }



    

    

    /**

     * 绑定布局:将每个子项的视图view添加进此线性布局LinearLayout中

     */

    public void bindLinearLayout()

    {

        int count = adapter.getCount();

        for (int i = 0; i < count; i++)

        {

            View v = adapter.getView(i, null, null);



            if (i != count - 1)

            {    //添加每项item之间的分割线

                 v = addLine(v);

            }

            addView(v, i);

        }

        setItemClickListener();

        Log.v("countTAG", "" + count);

    }



    /**

     * 添加每项item之间的分割线

     * 

     * @param view

     * @return

     */

    public View addLine(View view)

    {

        //分割线view

        View lineView = new View(view.getContext());



        // 将数据从dip(即dp)转换到px，第一参数为数据原单位（此为DIP），第二参数为要转换的数据值

        float fPx = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,

                (float) 0.5, view.getResources().getDisplayMetrics());

        int iPx = Math.round(fPx);



        LayoutParams layoutParams = new LayoutParams(

                LinearLayout.LayoutParams.MATCH_PARENT, iPx);

        lineView.setLayoutParams(layoutParams);

        lineView.setBackgroundColor(view.getSolidColor());



        LinearLayout ly = new LinearLayout(view.getContext());

        ly.setOrientation(LinearLayout.VERTICAL);



        ly.addView(view);

        ly.addView(lineView);



        return ly;

    }



    

    /**

     * 设置点击子项事件监听对象

    public void setOnItemClickListener(OnItemClickListener onItemClickListener)

        this.onItemClickListener = onItemClickListener;

        setItemClickListener();

    }

这种方法完全可以搞定，在原来开发当中 上面二个方法都可以搞定不知道这次为什么不行

我怀疑是布局问题

 <ScrollView

View Code

item布局是

    android:layout_height="match_parent"
