DrawerLayout的点击事件会穿透到底部，如何拦截？

DrawerLayout实现侧后，发现了一个问题。点击DrawerLayout的画面，会触发覆盖的底层页面的控件。由此说明点击事件穿透到了底部。但是我只需要触发抽屉布局里的控件，不想触发底层被覆盖的看不见的按钮，由此我想到的时让抽屉页面拦截点击事件即可。

解决方法：在侧滑监听里的onDrawerOpened监听中添加一个配置：

drawerView.setClickable(true);

如此就拦截了点击事件。具体代码如下： 

   //抽屉布局添加点击监听myDrawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {@Overridepublic void onDrawerSlide(View drawerView, float slideOffset) {super.onDrawerSlide(drawerView, slideOffset);//LogUtil.i("onDrawerSlide");}@Overridepublic void onDrawerOpened(View drawerView) {super.onDrawerOpened(drawerView);LogUtil.i("onDrawerOpened");drawerView.setClickable(true);}@Overridepublic void onDrawerClosed(View drawerView) {super.onDrawerClosed(drawerView);LogUtil.i("onDrawerClosed");}@Overridepublic void onDrawerStateChanged(int newState) {super.onDrawerStateChanged(newState);LogUtil.i("onDrawerStateChanged");}});
