Answer 1

在代码里的onmatch等方法中设置

Answer 2

SlipSwitchView 继承于什么类？

Answer 3

显示的是什么样？
截张图看一下
fill_parent是不是有问题？
                <com.soufun.zf.view.SlipSwitchView
                    android:id="@+id/ssv_switch"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    android:layout_toRightOf="@+id/ll_left"
                    android:layout_toLeftOf="@+id/ll_right"
                    android:layout_centerInParent="true"
                     />

Answer 4

 <ImageView 
            android:id="@+id/iv_intro"
            style="@style/fill"
            android:background="@drawable/home_intro"
            android:scaleType="fitXY"/>
这个是不是全屏的

Answer 5

我不设置margin属性他一直在一个布局的左上方。
