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);
    }

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;



/***
 * 
 * @author FreePC

 */
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);
    }
    
    

    /**
     * 设置适配器
     * 
     * @param adpater
     */
    public void setAdapter(BaseAdapter adpater)
    {
        this.adapter = adpater;
        bindLinearLayout();
    }

    /**
     * 获取适配器Adapter
     * 
     * @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
     * @param onItemClickListener
     */
    public void setOnItemClickListener(OnItemClickListener onItemClickListener)
    {
        this.onItemClickListener = onItemClickListener;
        setItemClickListener();
    }
    
    /**
     * 获取点击子项事件监听对象
     * @return
     */
    public OnItemClickListener getOnItemClickListener()
    {
        return onItemClickListen

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
        android:id="@id/myscrollview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/v_common_line_color"

                android:background="@drawable/layout_background_corners"

                <TextView

                android:divider="@color/cccccc"
                android:dividerHeight="0px"
                android:fadingEdge="none" />
        </RelativeLayout>
    </ScrollView>

item布局是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
        android:background="@color/v_common_line_color">

</LinearLayout>
