【中文标题】棒棒糖上完全透明的状态栏和导航栏【英文标题】：completely transparent status bar and navigation bar on lollipop 【发布时间】：2015-05-18 02:37:45 【问题描述】：我正在尝试制作一个 android 启动器。我想实现一个完全透明的状态栏和导航栏，这里是我的主题xml文件。
<resources>
<style name="Theme" parent="android:Theme.Material.Wallpaper.NoTitleBar">
<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:navigationBarColor">@android:color/transparent</item>
<item name="android:windowTranslucentStatus">false</item>
<item name="android:windowTranslucentNavigation">false</item>
</style>
</resources>
最后两项不行，棒棒糖上还有阴影。
这就是它的样子（注意实际上状态栏和导航栏上有一个阴影）：
我想要实现的目标（新星发射器）：
如何让状态栏和导航栏“透明”而不是“半透明”？
【问题讨论】：
【参考方案1】：更新
您可以通过在 Window 中设置 FLAG_LAYOUT_NO_LIMITS 标志以编程方式在 KitKat 上和之后实现相同的效果。
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
Window w = getWindow(); // in Activity's onCreate() for instance
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
如果您为布局设置背景资源（如颜色或图片），您将在状态栏“下方”看到颜色或图片。
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@color/primary_dark</item>
原答案
看起来android:windowTranslucentStatus 和android:windowTranslucentNavigation 应该是true 而不是false
<resources>
<style name="Theme" parent="android:Theme.Material.Wallpaper.NoTitleBar">
<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:navigationBarColor">@android:color/transparent</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
</resources>
另外，你的透明活动/容器布局需要这个属性集：
android:fitsSystemWindows="true"

【讨论】：
当我应用这个时，导航栏和状态栏仍然是灰色的半透明颜色，如 here 所示。在 Lollipop 和 M 上测试过。知道为什么吗？ 如果您为布局设置背景资源（如颜色或图片），您将在状态栏“下方”看到颜色或图片。检查编辑。 注意，我不需要主题部分，java代码就足够了。 这个答案不适合使用底部导航栏的应用，因为它失去了限制，将导航底部栏放到了手机软键上。 正确答案如何？ NO_LIMITS 使内容同时绘制在状态栏和导航栏上。目标只是使导航栏完全透明。【参考方案2】：我使用它是因为它保持状态栏和导航栏的高度
<!-- Base application theme. -->
<style name="theme" parent="android:Theme.Material.Wallpaper.NoTitleBar">
<item name="android:navigationBarColor">#00000000</item>
<item name="android:statusBarColor">#00000000</item>
</style>
不过，这确实需要 API 21+
【讨论】：
对我不起作用。您还对这些属性使用了哪些其他属性？【参考方案3】：适用于 API 29 及更高版本
<style name="Your.Theme">
<item name="android:navigationBarColor">@android:color/transparent</item>
<item name="android:enforceNavigationBarContrast">false</item>
</style>
【讨论】：
【参考方案4】：您可以使用这个 kotlin 扩展功能，它将状态栏设置为完全透明（在 API 23+ 上，View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR 标志在 API 23+ 上可用）和导航栏（在 API 27+ 上，View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR 标志在 API 27+ 上可用）否则它将在 API 21+ 上使用 systemUiScrim 颜色
fun Activity.transparentStatusAndNavigation(
systemUiScrim: Int = Color.parseColor("#40000000") // 25% black
)
var systemUiVisibility = 0
// Use a dark scrim by default since light status is API 23+
var statusBarColor = systemUiScrim
// Use a dark scrim by default since light nav bar is API 27+
var navigationBarColor = systemUiScrim
val winParams = window.attributes
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
systemUiVisibility = systemUiVisibility or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
statusBarColor = Color.TRANSPARENT
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
systemUiVisibility = systemUiVisibility or View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR
navigationBarColor = Color.TRANSPARENT
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
systemUiVisibility = systemUiVisibility or
View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
window.decorView.systemUiVisibility = systemUiVisibility
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
winParams.flags = winParams.flags or
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS or
WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
winParams.flags = winParams.flags and
(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS or
WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION).inv()
window.statusBarColor = statusBarColor
window.navigationBarColor = navigationBarColor
window.attributes = winParams
API 21+ API 27+
【讨论】：
只有这个答案才能使状态栏透明。最佳答案。【参考方案5】：100% 工作代码

【讨论】：
不适用于搭载 Android 9 的 Pixel 2 XL。还将底部软件按钮栏更改为没有可见按钮的白条。 @Potass 你必须为Api 23+ 添加标志View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR。请求状态栏以与浅色状态栏背景兼容的模式进行绘制。要使其生效，窗口必须请求 FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS 而不是 FLAG_TRANSLUCENT_STATUS。 developer.android.com/reference/android/view/… 玩设置以获得所需的效果。
也许你还需要添加 window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS) 否则你的条会变黑【参考方案6】：
以下代码是我在项目中使用的示例：
styles.xml
<style name="FadingActionBarTheme" parent="@android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">@style/FadingActionBarWidget</item>
</style>
<style name="FadingActionBarWidget.Transparent">
<item name="android:background">@android:color/transparent</item>
</style>
<style name="FadingActionBarTheme.TranslucentActionBar">
<item name="android:icon">@drawable/ic_ab_icon</item>
<item name="android:actionBarStyle">@style/FadingActionBarWidget.Transparent</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>
AndroidManifest.xml
<activity
android:name=".MyActivity"
android:label="@string/app_name"
android:theme="@style/FadingActionBarTheme.TranslucentActionBar">
</activity>
【讨论】：
【参考方案7】：您需要在主题中添加android:windowDrawsSystemBarBackgrounds 标志
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
或者在 onCreate() 中调用它
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
【讨论】：
这不会使导航栏透明。 @nhaarman 您还需要添加它。窗口 w = getWindow(); w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); 它通过 FLAG_LAYOUT_NO_LIMITS 使状态栏变得透明，但是我的操作栏隐藏了？你能帮忙吗？【参考方案8】：在状态栏下绘制布局：
值/样式.xml
<item name="android:windowTranslucentStatus">true</item>
values-v21/styles.xml
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@color/colorPrimaryDark</item>
使用已经处理过 fitSystemWindows 参数的 CoordinatorLayout/DrawerLayout 或创建自己的布局，如下所示：
public class FitsSystemWindowConstraintLayout extends ConstraintLayout
private Drawable mStatusBarBackground;
private boolean mDrawStatusBarBackground;
private WindowInsetsCompat mLastInsets;
private Map<View, int[]> childsMargins = new HashMap<>();
public FitsSystemWindowConstraintLayout(Context context)
this(context, null);
public FitsSystemWindowConstraintLayout(Context context, AttributeSet attrs)
this(context, attrs, 0);
public FitsSystemWindowConstraintLayout(Context context, AttributeSet attrs, int defStyleAttr)
super(context, attrs, defStyleAttr);
if (ViewCompat.getFitsSystemWindows(this))
ViewCompat.setOnApplyWindowInsetsListener(this, new android.support.v4.view.OnApplyWindowInsetsListener()
@Override
public WindowInsetsCompat onApplyWindowInsets(View view, WindowInsetsCompat insets)
FitsSystemWindowConstraintLayout layout = (FitsSystemWindowConstraintLayout) view;
layout.setChildInsets(insets, insets.getSystemWindowInsetTop() > 0);
return insets.consumeSystemWindowInsets();
);
setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
TypedArray typedArray = context.obtainStyledAttributes(new int[]android.R.attr.colorPrimaryDark);
try
mStatusBarBackground = typedArray.getDrawable(0);
finally
typedArray.recycle();
else
mStatusBarBackground = null;
public void setChildInsets(WindowInsetsCompat insets, boolean draw)
mLastInsets = insets;
mDrawStatusBarBackground = draw;
setWillNotDraw(!draw && getBackground() == null);
for (int i = 0; i < getChildCount(); i++)
View child = getChildAt(i);
if (child.getVisibility() != GONE)
if (ViewCompat.getFitsSystemWindows(this))
ConstraintLayout.LayoutParams layoutParams = (ConstraintLayout.LayoutParams) child.getLayoutParams();
if (ViewCompat.getFitsSystemWindows(child))
ViewCompat.dispatchApplyWindowInsets(child, insets);
else
int[] childMargins = childsMargins.get(child);
if (childMargins == null)
childMargins = new int[]layoutParams.leftMargin, layoutParams.topMargin, layoutParams.rightMargin, layoutParams.bottomMargin;
childsMargins.put(child, childMargins);
if (layoutParams.leftToLeft == LayoutParams.PARENT_ID)
layoutParams.leftMargin = childMargins[0] + insets.getSystemWindowInsetLeft();
if (layoutParams.topToTop == LayoutParams.PARENT_ID)
layoutParams.topMargin = childMargins[1] + insets.getSystemWindowInsetTop();
if (layoutParams.rightToRight == LayoutParams.PARENT_ID)
layoutParams.rightMargin = childMargins[2] + insets.getSystemWindowInsetRight();
if (layoutParams.bottomToBottom == LayoutParams.PARENT_ID)
layoutParams.bottomMargin = childMargins[3] + insets.getSystemWindowInsetBottom();
requestLayout();
public void setStatusBarBackground(Drawable bg)
mStatusBarBackground = bg;
invalidate();
public Drawable getStatusBarBackgroundDrawable()
return mStatusBarBackground;
public void setStatusBarBackground(int resId)
mStatusBarBackground = resId != 0 ? ContextCompat.getDrawable(getContext(), resId) : null;
invalidate();
public void setStatusBarBackgroundColor(@ColorInt int color)
mStatusBarBackground = new ColorDrawable(color);
invalidate();
@Override
public void onDraw(Canvas canvas)
super.onDraw(canvas);
if (mDrawStatusBarBackground && mStatusBarBackground != null)
int inset = mLastInsets != null ? mLastInsets.getSystemWindowInsetTop() : 0;
if (inset > 0)
mStatusBarBackground.setBounds(0, 0, getWidth(), inset);
mStatusBarBackground.draw(canvas);
main_activity.xml

【参考方案9】：对于那些想要在 KitKat 及更高版本上完全透明的状态栏和导航栏的人来说，使用 windowTranslucentNavigation 和 @Machado 的 Lollipop 答案存在一些小冲突，并防止这种冲突将样式分开
styles.xml
<style name="LockScreenStyle" parent="@android:style/Theme.Wallpaper.NoTitleBar">
<item name="android:windowTranslucentStatus" tools:targetApi="kitkat">true</item>
<item name="android:windowTranslucentNavigation" tools:targetApi="kitkat">true</item>

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
Window w = getWindow(); // in Activity's onCreate() for instance
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
w.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
【讨论】：
【参考方案10】：您还可以将 colorPrimary 和 colorPrimaryDark 的 alpha 更改为 00，然后将其添加到您的 onCreateMethod：
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
并将其添加到您的活动中：
android:fitsSystemWindows="true"
【讨论】：
【参考方案11】：这是为像我这样使用 Nativescript + Angular 的新手准备的。我从NTS marketplace 上的空白模板之一开始。然后对于我的特定用途，我需要顶部的状态栏始终透明（类似于 ios 样式），导航栏（底部）在某些组件/模块上完全透明（不是半透明！），而在其他组件/模块中不透明。如果一切都按照 NTS 设置的协议完成，你应该有一个类似于这个的 main.ts（我的解决方案的先决条件）
我把我的作品分成两部分，先上，后下。对于顶部，我发现 this answer 有效。所以你应该有一个如下所示的 main.ts 文件。
import platformNativeScriptDynamic from "@nativescript/angular";
import AppModule from "./app/app.module";
import * as application from "tns-core-modules/application";
import Color from "@nativescript/core";
platformNativeScriptDynamic().bootstrapModule(AppModule);
declare var android;
application.android.on(application.AndroidApplication.activityCreatedEvent, (event) =>
const activity = event.activity;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP)
activity.getWindow().addFlags(android.view.WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
activity.getWindow().clearFlags(android.view.WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
activity.getWindow().addFlags(android.view.WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
activity.getWindow().setStatusBarColor(android.graphics.Color.TRANSPARENT);
activity.getWindow().setNavigationBarColor(android.graphics.Color.TRANSPARENT);
else
activity.getWindow().addFlags(android.view.WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
activity.getWindow().setNavigationBarColor(android.graphics.Color.TRANSPARENT);
const parent = activity.findViewById(android.R.id.content);
for (let i = 0; i < parent.getChildCount(); i++)
const childView = parent.getChildAt(i);
if (childView instanceof android.view.ViewGroup)
childView.setFitsSystemWindows(true);
childView.setClipToPadding(true);
);
然后为了增加导航栏的透明度，我遵循this 并将其添加到上面 main.ts 文件的第 24 行。 activity.getWindow().addFlags(android.view.WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
现在请注意，还有我们必须尊重的 styles.xml 文件，所以我的 styles.xml 文件 (App_Resources\Android\src\main\res\values\styles.xml) 如下所示：
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
