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);
    }

    @Override
    public 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>

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"};

@Override
protected 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() {
        @Override
        public 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();
        }
    });

}
