Question

我有一个小问题。我不明白工具栏问题。例如，我在活动中添加了工具栏但未看到通知面板背景（“primary_dark”）。我尝试了一切，但没有解决。

public class AboutActivity extends AppCompatActivity {
    Toolbar toolbar;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_about);
        final Toolbar toolbar = (Toolbar) findViewById(R.id.about_activity_toolbar);
        toolbar.setTitleTextColor(Color.WHITE);
        setSupportActionBar(toolbar);
        toolbar.setTitle("About");

    }
}

Answer 1

在Style.xml文件中，更改colorPrimaryDark颜色。

<item name="colorPrimaryDark">@color/colorPrimaryDark</item>

同时将延伸范围从ActionBarActivity更改为AppCompatActivity。

Answer 2

只需用此

替换styles.xml即可

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="BaseAppTheme"/>

    <style name="BaseAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowBackground">@color/colorWhite</item>
        <item name="colorPrimary">@color/colorPrimaryDark</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
</resources>

并且您的styles.xml（v21）将如下所示

<resources>
    <style name="AppTheme" parent="BaseAppTheme">
         <!-- improve animations -->
    <item name="android:windowContentTransitions">true</item>
    <item name="android:windowAllowEnterTransitionOverlap">true</item>
    <item name="android:windowAllowReturnTransitionOverlap">true</item>
    <item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
    <item name="android:windowSharedElementExitTransition">@android:transition/move</item>
    </style>
</resources>

在清单中，为应用程序定义主题，例如在应用程序内部标记

<application
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme">

/*

   your activities

*/

</application>

问题是您已为棒棒糖前设备指定了colorPrimaryDark。您必须将styles.xml（v21）的父级定义为在styles.xml中定义colorPrimaryDark的父级。
