    </LinearLayout>

     </LinearLayout>
</ScrollView>

</RelativeLayout>

I don't know to correct this error. In xml layout i can see the button, but in the emulator its not visible or button not scrolled. also i want this two button in same line with left and right alignment.

您在滚动视图中指定第二个线性布局为

 <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="454dp"
        android:layout_gravity="bottom"
        android:layout_marginLeft="20sp"
        android:layout_marginRight="20sp"
        android:orientation="vertical" >

改成

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:layout_marginLeft="20sp"
        android:layout_marginRight="20sp"
        android:orientation="vertical" >

您指定的高度已修复，为什么它不显示...

<LinearLayout 

            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:layout_margin="3dp"         
            >

                      <Button 
                android:id="@+id/login_btn"
                android:layout_width="wrap_content"
                android:layout_height="50dp"
                android:layout_weight="0.5"
                android:text="Login"
                />

            <Button 
                android:id="@+id/cancel_btn"
                android:layout_width="wrap_content"
                android:layout_height="50dp"
                android:layout_weight="0.5"
                android:text="Cancel"
                />
            </LinearLayout>

将 ScrollView 的高度设置为match_parent

<ScrollView
android:id="@+id/ScrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >
