通过全屏活动在Android Lollipop上设置navigationBar颜色 [英] Set navigationBar color on Android Lollipop with Full screen activity

问题描述

是否可以在全屏活动中设置导航栏颜色?

Is there a way to set the navigationbar color in a fullscreen activity?

if(android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setNavigationBarColor(getResources().getColor(R.color.Theme_color));

这行是我的主题风格:

<item name="android:navigationBarColor" tools:targetApi="21">#E64A19</item>

两者都会在我的活动布局上方产生相同的透明导航栏...

Both resulting in the same transparant navbar above my activities layout...

代码:

积极性:

@Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                //Remove title bar
                this.requestWindowFeature(Window.FEATURE_NO_TITLE);

                //Remove notification bar
                this.getWindow()
    .setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

                setContentView(R.layout.activity_account);

                if (getResources().getBoolean(R.bool.portrait_only)) {
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                }

                if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                    getWindow()
        .setNavigationBarColor(getResources().getColor(R.color.Theme_color));
                }


                //other code ... (irrelevant)

主题:

<style name="FullscreenTheme" parent="android:Theme.NoTitleBar">
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowBackground">@null</item>
        <item name="metaButtonBarStyle">@style/ButtonBar</item>
        <item name="metaButtonBarButtonStyle">@style/ButtonBarButton</item>
        <item name="android:navigationBarColor" tools:targetApi="21">#E64A19</item>
</style>

结果是黑色导航栏.但是我想要一个橙色的(#E64A19)导航栏.

The result is a black navigationbar. But I want a orange (#E64A19) navigation-bar.

结果:

推荐答案

我的解决方案:

一旦我从主题样式(以及除<item name="android:navigationBarColor" tools:targetApi="21">#E64A19</item>以外的所有其他内容)中删除了parent="android:Theme.NoTitleBar"属性，问题就在于生成的代码(XML主题)，我的导航栏变成了橙色！

The problem lied with the generated code (XML theme) once I'd deleted the parent="android:Theme.NoTitleBar"attribute from my theme style (and everything else except <item name="android:navigationBarColor" tools:targetApi="21">#E64A19</item>) my navbar became orange!
