TextView 添加Selector的背景和颜色不能正常运行



TextView 添加Selector的背景和颜色不能正常运行，原因，textview未设置clickable

<TextView
        android:id="@+id/tv_edit"
        android:layout_width="63dp"
        android:layout_height="25dp"
        android:layout_alignParentRight="true"
        android:layout_margin="10dp"
        android:background="@drawable/background_donwload_edit"
        android:gravity="center"
        android:text="@string/edit"
        android:textColor="@color/kk_download_edit_color"
        android:textSize="12sp"

android:clickable="true"
/>

background_donwload_edit.xml文件
