scrollView中实现listView的解决方法
scrollView中实现listView的解决方法
1.自定义view，采用继承LinearLayout的方式
2.继承Adapter，本例中采用两种方式进行演示：
1.ArrayAdapter 2.BaseAdapter
先是第一种ArrayAdapter:

"" : content);}convertView.setTag(position);return convertView;}}package com.terry.widget;import android.content.Context;import android.util.AttributeSet;import android.view.View;import android.widget.LinearLayout;public class LinearLayoutForListView extends LinearLayout {private ArrayAdapterForLinearLayout adapter = null;private OnClickListener onClickListener = null;public LinearLayoutForListView(Context context) {super(context);}public LinearLayoutForListView(Context context, AttributeSet attrs) {super(context, attrs);// TODO Auto-generated constructor stub}/** * 绑定布局 */public void bindLinearLayout() {int count = adapter.getCount();for (int i=0;i<count;i++) {View view = adapter.getView(i, null, null);view.setOnClickListener(this.onClickListener); //用来消除最后一个下划线if (i == count-1) {LinearLayout ly = (LinearLayout) view;ly.removeViewAt(1);}addView(view,i);}}public ArrayAdapterForLinearLayout getAdapter() {return adapter;}public void setAdapter(ArrayAdapterForLinearLayout adapter) {this.adapter = adapter;bindLinearLayout();}public OnClickListener getOnClickListener() {return onClickListener;}public void setOnClickListener(OnClickListener onClickListener) {this.onClickListener = onClickListener;}}package com.terry.widget;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.os.Bundle;import android.widget.ScrollView;public class Main extends Activity { private LinearLayoutForListView lv = null; private List<String> list = new ArrayList<String>();private ScrollView scrollView = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); scrollView = (ScrollView) findViewById(R.id.MAIN_VIEW_DETAIL);scrollView.setSmoothScrollingEnabled(true);scrollView.fullScroll(ScrollView.FOCUS_UP);scrollView.fullScroll(ScrollView.FOCUS_DOWN); lv = (LinearLayoutForListView) findViewById(R.id.ListView01); for (int i=0;i<40;i++) { list.add("name"+i); } ArrayAdapterForLinearLayout layoutadapter = new ArrayAdapterForLinearLayout(this, R.layout.test, R.id.TextView01, list); lv.setAdapter(layoutadapter); }}<?xml version="1.0" encoding="utf-8"?><ScrollView xmlns:android="http://schemas.android.com/apk/res/android"android:layout_height="fill_parent" android:layout_width="fill_parent"android:id="@+id/MAIN_VIEW_DETAIL" android:scrollbars="vertical"><com.terry.widget.LinearLayoutForListView android:orientation="vertical" android:layout_width="450px" android:layout_height="fill_parent" android:id="@+id/ListView01"></com.terry.widget.LinearLayoutForListView></ScrollView>
