带有抽屉的Android Google搜索栏 [英] Android Google Search Bar with Drawer

问题描述

我的应用当前通过单一活动方法实现(使用具有一个主要活动和多个片段的导航体系结构组件).我目前正在使用带抽屉的工具栏.

My app is currently implemented with the Single activity approach (Using navigation architecture component with one main activity and several fragments). I am currently using a toolbar with a drawer.

我的应用当前如下所示:

My app currently look like this:

然而，在现代的google应用(Google照片，gmail等)中，Google实现了一种新的导航方式，即使用其中包含已实现的抽屉的搜索字段进行导航，如下所示:

However in the modern google apps (Google photos, gmail etc..), Google has implemented a new way of navigating using a search field with an implemented drawer in it as shown below:

我想将此搜索栏和抽屉菜单完全替换为Google工具栏上的工具栏.

I want to replace this toolbar with a search bar and the drawer menu exactly like the Google apps.

有人可以通过一些代码帮助我实现这一目标吗?

Can someone help me with some code on how to achieve this?

我的主要活动如下:

有人可以为我提供一些有关如何实现这种搜索栏的代码的指导吗?

Can someone please guide me with some code on how to implement this kind of search bar?

推荐答案

如果您仍在寻找通过应用抽屉图标实现gmail样式搜索栏的方法，请使用工具栏，只需添加导航图标并包装editText内部:

if you are still looking for a way to implement a gmail style search bar with an app drawer icon, use the toolbar, simply add navigation icon and wrap an editText inside:

<androidx.appcompat.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:navigationIcon="@drawable/ic_menu">
    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</androidx.appcompat.widget.Toolbar>

然后在活动中设置工具栏:

Then set the toolbar in the activity:

val toolbar: Toolbar = findViewById(R.id.toolbar)
setSupportActionBar(toolbar)

并实现onOptionsItemSelect侦听器:

And implement the onOptionsItemSelect listener:

override fun onOptionsItemSelected(item: MenuItem): Boolean {
    // do desired stuff here
    return super.onOptionsItemSelected(item)
}

如果您还想拥有浮动样式和消失的行为，请将工具栏包装在appBarLayout中，然后设置app:layout_scrollFlags ="scroll | enterAlways | snap":

If you also want to have the floating style and disappearing behavior, wrap the toolbar in an appBarLayout and set app:layout_scrollFlags="scroll|enterAlways|snap":

<com.google.android.material.appbar.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginHorizontal="24dp"
    android:layout_marginTop="2dp"
    android:background="@android:color/transparent">
    app:elevation="0dp">

    <androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:elevation="4dp"
        app:navigationIcon="@drawable/ic_menu"
        app:contentInsetStartWithNavigation="0dp"
        app:layout_scrollFlags="scroll|enterAlways|snap">

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"/>
</androidx.appcompat.widget.Toolbar>

</com.google.android.material.appbar.AppBarLayout>

以下模仿样式和行为的细节值得一提:

The following details to mimic the style and the behavior are worth to mention:

appBarLayout

appBarLayout

1. 水平边距，以使栏不覆盖整个顶部
2. 背景设置为圆形矩形
3. 边距顶端要留出一点空间
4. 提升到0dp，因此appBarLayout没有阴影

工具栏

1. app:contentInsetStartWithNavigation ="0dp"，否则图标和editText之间的边距太大

EditText

1. 背景透明，因此下划线将消失

edit:几乎忘了！非常重要的一点:父级布局必须为CoordinatorLayout，否则在recyclerview中滚动时不会有任何反应edit2:将应用栏布局的高度更改为0dp，因此不会有阴影

edit: Almost forgot! Very important point: The parent layout has to be CoordinatorLayout, otherwise there will be no reactions to scrolling inside the recyclerview edit2: changed eleveation of the appbar layout to 0dp so there wont be any shadow
