设置android:divider="@null"也即不为listview设置分割线 设置android:divider="@android:color/transparent"就是分割线透明，相当于没有分割线，不过分割线还是会占一些位置 设置android:dividerHeight="0dp"设置分割线高度为0，也就没有分割线了
lvMain = (ListView)view.findViewById(R.id.list_bookcontent);
lvMain.setDivider(null);//去除listview的分割线

如果item里面嵌套了抢焦点的控件（比如Button ，CheckBox等），那么点击item的时候，button等抢焦点的控件会抢先反应，这是因为item的焦点被button等控件抢了，想要item有自己的焦点，button等控件有自己的焦点的话，需要在item的根控件里面设置：android:descendantFocusability="blocksDescendants"，这个属性值表示子有字的焦点，父有父的焦点：
该属性是当一个为view获取焦点时，定义viewGroup和其子控件两者之间的关系。
属性的值有三种：
beforeDescendants：viewgroup会优先其子类控件而获取到焦点
afterDescendants：viewgroup只有当其子类控件不需要获取焦点时才获取焦点
blocksDescendants：viewgroup会覆盖子类控件而直接获得焦点，也就是各有各的焦点
如果还是抢焦点的话，在抢焦点的子控件里面设置android:focusable="false"，基本上是没有抢焦点的问题的。
