ScrollView滚动视图实例：

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>  <LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical">     <ScrollView        android:id="@+id/scrollView"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:scrollbarStyle="outsideOverlay" >        <TextView            android:id="@+id/textView"            android:layout_width="fill_parent"            android:layout_height="wrap_content" />    </ScrollView>   </LinearLayout>  

MainActivity.java:

import android.app.Activity;import android.os.Bundle;import android.widget.TextView;public class MainActivity extends Activity {    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);       TextView textView = (TextView)findViewById(R.id.textView);       textView.setText("a\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na\na");        }}  

运行结果：
一旦需要现实的内容超出屏幕，则滚动条就会出现。
