Question

我正在使用工具栏的当前样式和主题并使用支持库。我正在扩展AppCompatActivity而不是正常活动。

<style name="AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">      <item name="android:windowNoTitle">false</item>
        <item name="android:windowActionBar">true</item>
    </style>

我收到错误，下面是堆栈跟踪，

主要活动

当我尝试应用黑暗主题时出现问题。parent="Theme.AppCompat.DayNight.NoActionBar"对于此属性，我如何知道哪些主题可以使用哪些主题不起作用？应该怎样做才能应用不会出现任何错误的黑暗主题？

让我知道还需要什么代码，我会相应地编辑问题。

编辑1 根据评论中的要求，我添加了Activity onCreate（）方法

初始化

 DataBaseHelper dbhelper;
    ListView notesView;
    CustomCursor dataCursor;
    int ROW_NUMBER;
    Cursor passCursor;
    Toolbar bar;



@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        dbhelper = new DataBaseHelper(this);

        passCursor = dbhelper.fetchAllNotes();
        dataCursor = new CustomCursor(this,passCursor);

        notesView = (ListView)findViewById(R.id.listView);
       notesView.setAdapter(dataCursor);
        notesView.setOnItemClickListener(this);

        bar = (Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(bar);

    }

Answer 1

如果您使用<item name="android:windowActionBar">true</item>作为supportActionBar，则从主题文件中删除Toolbar

错误：ToolBar主题和Dark主题
