我的 xml 编辑器中出现了工具栏设计和呈现问题之间的冲突。

我想渲染工具栏的设计,但是好像已经渲染过了,找不到在哪里。

这里是java Activity 类。我在调用 setSupportActionBar第 21 行 处遇到错误:


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 Activity 布局文件:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

xmlns:app="http://schemas.android.com/apk/res-auto"

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="?attr/actionBarSize"
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:
