# PagerAdapter

主要方便TabLayout和ViewPager进行结合使用

### 具体使用(案例)

代码

xml布局

```xml

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <data>

    </data>

    <androidx.constraintlayout.widget.ConstraintLayout android:layout_width="match_parent"
        android:layout_height="match_parent">

        <com.google.android.material.tabs.TabLayout android:id="@+id/tab_layout"
            android:layout_width="match_parent" android:layout_height="@dimen/gwm_dp_50"
            app:tabMode="scrollable" app:layout_constraintTop_toTopOf="parent" />

        <androidx.viewpager.widget.ViewPager android:id="@+id/vp_view"
            android:layout_width="match_parent" android:layout_height="0dp"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintTop_toBottomOf="@id/tab_layout" />

    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

```

绑定ViewPager

activity或者fragment里进行设置

```kotlin
//Fragment集合
private val mPageList = arrayListOf<Fragment>(
    FlowFragment(),
    ShapeFragment(),
    SearchFragment(),
    ActionBarFragment(),
    KeyboardFragment()
)
//标题集合 和Fragment保持一致
private val mPageTitle = arrayListOf("流式布局", "Shape背景", "自定义搜索框", "标题栏", "数字键盘")
override fun initData() {
    val fragmentPagerAdapter = FragmentPagerAdapter(mPageList, mPageTitle)
    mBinding.vpView.adapter = fragmentPagerAdapter
    mBinding.tabLayout.setupWithViewPager(mBinding.vpView)
}

```
