布局与底部导航栏重叠的问题

自问自答
build()之前调用setDecorView即可
activity中如下
```
.setDecorView(activity.getWindow().getDecorView().findViewById(android.R.id.content))
.build();
```
Frament中类似 下面是demo中的例子：

```
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.fragment_test, null);
return mView;
}

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mFrameLayout = (FrameLayout) mView.findViewById(R.id.fragmen_fragment);
}

.setDecorView(mFrameLayout)//非dialog模式下,设置ViewGroup, pickerView将会添加到这个ViewGroup中
```
