那是我的菜单

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:title="@string/search"
        android:id="@+id/action_search"
        android:icon="@drawable/ic_search_24dp"
        app:showAsAction="ifRoom|collapseActionView"
        app:actionViewClass="android.support.v7.widget.SearchView"/>
</menu>

这是我的onCreateOptionsMenu;

And here my onCreateOptionsMenu;

menu.clear();
        inflater.inflate(R.menu.menu_search, menu);
        MenuItem searchItem = menu.findItem(R.id.action_search);
        searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                //Perform the final search

                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                //Text has changed, apply filtering?

                return false;
            }
        });

我希望有人能帮助我. :)

推荐答案

我也遇到了这个问题，我已经将工具栏高度更改为绝对值，而不是wrap_content并解决了问题.我不知道为什么，但是我认为这个问题与CoordinatorLayout和工具栏的高度有关，某些东西打破了SearchView的高度.如果我使用LinearLayout而不是CoordinatorLayout和AppBarLayout可以工作.

i have this problem too, i've changed Toolbar height to absolute value instead of wrap_content and problem solved. i don't know why but i think this issue is related to CoordinatorLayout and height of toolbar, something breaks the SearchView height. if i use LinearLayout instead of CoordinatorLayout and AppBarLayout it works.

menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_search_white_24dp"
        android:orderInCategory="100"
        android:title="@string/action_search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="always|collapseActionView" />
</menu>

layout.xml

layout.xml

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

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="@dimen/toolbar_height"
            android:paddingTop="@dimen/toolbar_top_padding"
            android:background="?attr/colorPrimary"
            app:title="@string/drawer_item_publisher_customization"
            app:layout_scrollFlags="scroll|enterAlways|snap"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tabLayout"
            app:tabGravity="fill"
            style="@style/DefaultTabLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

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

    <android.support.v4.view.ViewPager
        android:id="@+id/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

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

toolbar_height值:

toolbar_height value:

<dimen name="toolbar_height">75dp</dimen>

在绝对高度值之前(layout_height:"wrap_content"):

Before absolute height value (layout_height:"wrap_content"):

绝对高度值后(layout_height:"75dp"):

After absolute height value (layout_height:"75dp"):
