【问题描述】：

我的 xml 编辑器中的工具栏设计和呈现问题之间存在冲突。

我想渲染工具栏设计，但是好像已经渲染了，找不到位置。

这里是java活动类。我在line 21 收到错误，其中调用了setSupportActionBar：

public class NoteActivity extends AppCompatActivity 

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_note);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        Spinner spinnerCourses = findViewById(R.id.spinner_courses);

        List<CourseInfo> courses = DataManager.getInstance().getCourses();
        ArrayAdapter<CourseInfo> adapterCourses =
                new ArrayAdapter<>(this, android.R.layout.simple_spinner_item);
        adapterCourses.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        spinnerCourses.setAdapter(adapterCourses);

    

    @Override
    public boolean onCreateOptionsMenu(Menu menu) 
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_note, menu);
        return true;
    

    @Override
    public boolean onOptionsItemSelected(MenuItem item) 
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) 
            return true;
        

        return super.onOptionsItemSelected(item);
    

这是我的styles.xml 文件：

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar"/>

    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light"/>

</resources>

..这是我的活动布局文件：

<?xml version="1.0" encoding="utf-8"?>
<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_
    tools:context="com.emmanuelani.notekeeper.NoteActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_
        android:layout_
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_
            android:layout_
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay"/>

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

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

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

我收到以下错误：

【参考方案1】：

我认为您应该检查 AndroidManifest.xml 文件，其中您将哪种样式应用于您面临问题的活动。

如果您应用了“AppTheme”主题，那么您应该尝试“AppTheme.NoActionBar”，或者如果您没有添加主题，默认情况下会选择“AppTheme”，因此您必须将活动主题更改为“AppTheme.NoActionBar”在 AndroidManifest.xml 中

还添加更改您的“AppTheme.NoActionBar”主题如下，并将 AndroidManifest.xml 中的此主题应用到“NoteActivity”。

<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
</style>

【讨论】：

我将@style/AppTheme.NoActionBar 添加到清单中的activity 标记中。仍然没有变化。它变成了红色。

我刚遇到这个问题。问题是 values/styles.xml 不是我在“AppTheme”下预期的字符串。因此，请确保您的样式文件中存在“AppTheme.NoActionBar”。
