        android:layout_alignParentRight="true"
        android:layout_below="@+id/fbedittext"
        android:layout_marginTop="22dp"
        android:lines="7"
        android:scrollbars="vertical"

</ScrollView> 
    <ImageView

</RelativeLayout>

推荐答案

1。通过XML

<ScrollView android:id="@+id/textAreaScroller" 
    android:layout_width="fill_parent" 
    android:layout_height="173px" 
    android:layout_x="0px" 
    android:layout_y="25px" 
    android:scrollbars="vertical">
<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/fbedittext"
    android:layout_alignParentRight="true"
    android:layout_below="@+id/fbedittext"
    android:layout_marginTop="22dp"
    android:lines="7"        
    android:text="@string/fbtext" />
</ScrollView>

2.Via code

ScrollView scroller = new ScrollView(this);
TextView tv=(TextView)findViewById(R.id.textView1);
scroller.addView(tv);

或

把下面的属性在你的 ＆LT; TextView的＆GT;

android:scrollbars = "vertical"

在code

tv.setMovementMethod(new ScrollingMovementMethod());
