Hide Keyboard does not re-expand the layout

Question

I implemented CoordinatorLayout with AppBarLayout and Toolbar to hide toolbar when scrolling and everything working greet.
The problem appears when i implemented search view.
Here is my activity_main layout:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/main_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

        <View
            android:id="@+id/appbar_bottom"
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="@android:color/transparent"
            android:visibility="invisible"/>

    </android.support.design.widget.AppBarLayout>

</android.support.design.widget.CoordinatorLayout>

And my fragment_layout :

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/projects_swipe_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/projects_recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"/>

</android.support.v4.widget.SwipeRefreshLayout>

Normal layout RecyclerView

The problem here when keyboard is hidden.

Answer 1

You can control the expandable behavior of the appBarLayout :

first By putting these lines in Manifest, you disable the appbar collapse effect due to the keyboard when it shows and when it hides.

<activity android:name="MyActivity"
   ...
   android:windowSoftInputMode="adjustNothing"
   ...
</activity>

Then, simply expand/collapse appbar whenever you want :

appbar.setExpanded(true); / appbar.setExpanded(false);

you could collapse when EditText hasFocus, and expand when outter views get touch..

(someView.setOnTouchListener ...)

Add android:windowSoftInputMode="adjustPan" to manifest - to the corresponding activity:

<activity android:name="MyActivity"
   ...
   android:windowSoftInputMode="adjustPan"
   ...
</activity>
