Android实现 ScrollView+ListView无滚动条滚动，即ListView的数据会全部显示完，但Listview无滚动条。

核心代码如下：

1. NoScrollListView.java

/*** * 自定义ListView子类，继承ListView * @author Administrator * */public class NoScrollListView extends ListView {public NoScrollListView(Context context) {super(context);}public NoScrollListView(Context context, AttributeSet attrs) {super(context, attrs);}public NoScrollListView(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);}@Overridepublic void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);super.onMeasure(widthMeasureSpec, expandSpec);}}

2. res > layout > activity_main.xml

<?xml version="1.0" encoding="utf-8"?><ScrollView xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/ScrollView"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:background="#FFF4F4F4"    android:scrollbars="vertical" >    <LinearLayout        android:id="@+id/LinearLayout"        android:gravity="center_horizontal"        android:background="#FFF4F4F4"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:orientation="vertical" >        <TextView            android:id="@+id/textView1"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="2dp"            android:layout_marginTop="20dp"            android:text="This's a listView..." />                <!--原： <ListView> -->        <com.example.listviewdemo.NoScrollListView            android:id="@+id/listView1"            android:layout_width="fill_parent"            android:layout_height="fill_parent"             android:dividerHeight="0.0dip"            android:fadingEdge="none"            android:cacheColorHint="#FFF4F4F4"/>                </LinearLayout></ScrollView>

2. res > layout > activity_main.xml
这里注意：原来的<ListView 改为<com.example.listviewdemo.NoScrollListView 。

3.MainActivity

private String[] nameList = {"Miley Cyruc","Alice Keys","Jewel","Dublin","Kelly Clarkson", "Mariah Carey","Sheen","Adele","Avril Lavigne","Taylor Swift"};@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ListView lv = (ListView) findViewById(R.id.listView1);ArrayAdapter adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, nameList);lv.setAdapter(adapter);//lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);//选择效果//listView注册一个元素点击事件监听器lv.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {Log.d(TAG, "//:"+MainActivity.this.nameList[arg2]);Toast.makeText(MainActivity.this, "Hey, "+nameList[arg2], Toast.LENGTH_LONG).show();}}); }

2. res > layout > activity_main.xml

效果图：
