navigationicon - Android Toolbar 自定义actionBarSize导致返回按钮、菜单按钮栏高度不正常 ，偏移

Question

问题定位：

dimens.xml

<dimen name="actionbar_size">48dp</dimen>

styles.xml

  <style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowBackground">@color/backgroundGray</item>
        <item name="android:listpider">@null</item>
        <item name="actionBarSize">@dimen/actionbar_size</item>
    </style>

如果自定义了actionBarSize 则就会出现如下问题

如图所示 返回按钮不居中，偏移了

    <!-- ToolBar -->
    <style name="ToolBarStyle" parent="Theme.AppCompat">
        <item name="android:actionBarSize">@dimen/actionbar_size</item>
        <item name="actionMenuTextColor">@android:color/black</item>
    </style>

    <!-- Toolbar popup主题 -->
    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light"/>

<android.support.v7.widget.Toolbar 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"
                                   android:id="@+id/toolbar"
                                   android:layout_width="match_parent"
                                   android:layout_height="wrap_content"

                                   app:contentInsetRight="0dp"
                                   app:contentInsetStart="0dp"

                                   app:paddingStart="0dp"
                                   app:titleMarginStart="0dp"
                                   android:minHeight="?attr/actionBarSize"

                                   app:popupTheme="@style/AppTheme.PopupOverlay"
</android.support.v7.widget.Toolbar>                                   

Answer 2

setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.ic_action_back);

Answer 3

You have customized the title, why do you have to use toolbar. . Wouldn’t it be nice to customize everything?

Answer 4

How did LZ solve it later? I also encountered this problem

Answer 5

I would like to ask, is the height of the menu item incapable of being raised? Do the top and bottom margins have to exist?
