使用selector制作点击动作后控件变换颜色，可以编译但是报错了？

按照网上资料学习了一下使用selector给按钮在focus和press的时候变色，但是报错了没法实现，很苦恼，请求各位帮助！！

activity_grid_view.xml //这个是我整个的布局文件 截图了使用到变换颜色的部分

```java
<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <GridView
            android:id="@+id/gridView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:horizontalSpacing="2dp"
            android:numColumns="2"
            android:verticalSpacing="2dp"
            android:focusable="true"
            android:background="#ededed">
        </GridView>
    </LinearLayout>
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <View
            android:layout_height="2dp"
            android:layout_width="match_parent"
            android:background="#ffffff" />
    </LinearLayout>

将selector_btn_click_bg.xml中的android:color全部改为android:drawable试试

selector_btn_click_bg.xml你确认下第七行android:drawable="@drawable/grey" 而你这文件其他地方都是使用 android:color，是不是写错了
