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。
