我希望标签(工具栏标题)居中对齐。我应该怎么做?我参考了一些逻辑,没有发现它们有效,它们也不起作用。所以请引导我通过它。
这是导航文件:
<?xml version="1.0" encoding="utf-8"?>
<navigation 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/mobile_navigation"
app:startDestination="@id/current_weather_fragment">
<fragment
android:id="@+id/current_weather_fragment"
android:name="com.example.wheatherapp.UI.Weather.CurrentWeather.CurrentWeatherFragment"
android:label="current_weather_fragment"
tools:layout="@layout/current_weather_fragment" />
<fragment
android:id="@+id/future_weather_fragment"
android:name="com.example.wheatherapp.UI.Weather.FutureWeather.FutureWeatherListFrag.FutureWeatherFragment"
android:label="future_weather_fragment"
tools:layout="@layout/future_weather_fragment" />
<fragment
android:id="@+id/future_detail_weather"
android:name="com.example.wheatherapp.UI.Weather.FutureWeather.FutureDetailFrag.FutureDetailWeather"
android:label="future_detail_weather_fragment"
tools:layout="@layout/future_detail_weather_fragment" />
<fragment
android:id="@+id/setting_fragment"
android:name="com.example.wheatherapp.UI.Setting.SettingFragment"
android:label="SettingFragment" />
</navigation>
这是maintactivity.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

android:layout_height="match_parent"

app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:theme="@style/ToolbarTheme">
<androidx.appcompat.widget.Toolbar

android:layout_width="match_parent"

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

android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintTop_toBottomOf="@id/appbar_layout"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toTopOf="@id/bottom_nav"
app:navGraph="@navigation/mobile_navigation"
app:defaultNavHost="true"
android:name="androidx.navigation.fragment.NavHostFragment" />
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="@+id/bottom_nav"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:menu="@menu/bottom_nav_menu"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
