Question

在我的styles.xml中

<!-- Base application theme. -->
<style name="MainAppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:textAllCaps">false</item>
    <item name="colorControlNormal">@android:color/white</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <!--item name="colorPrimaryDark">@color/colorPrimaryDark</item>-->
    <!--   theme UI controls like buttons, checkboxes and text fields, cursor or progress bar-->
    <item name="colorAccent">@color/colorAccent</item>
    <!-- hide action bar -->
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

在Manifest.xml中

活动中：

 mToolbar = (Toolbar) findViewById(R.id.toolBar);
            setSupportActionBar(mToolbar);
            getSupportActionBar().setDisplayShowTitleEnabled(false);

布局：

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

    <include layout="@layout/tool_bar"/>

    <!-- Framelayout to display Fragments -->
    <FrameLayout
            android:id="@+id/frame_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
    </FrameLayout>
</LinearLayout>

    </androidx.constraintlayout.widget.ConstraintLayout>

</LinearLayout>

但在工具栏中，所有字符均大写。但是我只需要大写的首字母即可。

工具栏所有大写禁用
