# 界面

> 所有界面继承`BaseFragment`,`BaseActivity`,`BaseListActivity`等
>
> 页面`layout`跟节点必须为`layout`

```xml
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
</layout>
```

## 列表页面

### 纯列表

> `BaseListActivity`

### 自定义布局列表

> `BaseListFormLayoutActivity` 
>
> 布局列表部分必须使用下面的方法和id

```xml
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    android:id="@+id/baseRefreshLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.xuqm.base.view.EmptyView
        android:id="@+id/baseEmptyView"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/baseRecyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:overScrollMode="never" />

    </com.xuqm.base.view.EmptyView>

</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

binding.btn1.setOnClickListener {
    
}
```

## 导航栏
