棒棒糖上完全透明的状态栏和导航栏

标签： android android-5.0-lollipop

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>

最后两个项目不起作用，棒棒糖上仍然有一个阴影。

这就是它的样子（注意状态栏和导航栏上实际上有一个阴影）： enter image description here

我想要达到的目标（新星发射器）：

如何使状态栏和导航栏“透明”而不是“半透明”？

更新

您可以在KitKat上以编程方式实现相同的效果，然后在FLAG_LAYOUT_NO_LIMITS内设置Window标记。

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);
        }

如果您为布局设置了背景资源（，如颜色或图片），您将看到下面的＃34;颜色或图片。状态栏。 

<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@color/primary_dark</item>

原始答案

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>

此外，您的透明活动/容器布局需要设置此属性：

android:fitsSystemWindows="true"

我使用它，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>

这确实需要API 21+

答案 2 :(得分：3)

您需要在主题

中添加android:windowDrawsSystemBarBackgrounds标记 
<item name="android:windowDrawsSystemBarBackgrounds">true</item>

或者在onCreate（）

中调用它 
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

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>

的AndroidManifest.xml 

<activity
    android:name=".MyActivity"
    android:label="@string/app_name"
    android:theme="@style/FadingActionBarTheme.TranslucentActionBar">
</activity>

对于API 29及更高版本使用

<style name="Your.Theme">
    <item name="android:navigationBarColor">@android:color/transparent</item>
    <item name="android:enforceNavigationBarContrast">false</item>
</style>

答案 5 :(得分：1)

在状态栏下绘制布局：

值/ styles.xml 

regex='tag="answer_yes"[[:space:]]+value="([^"]+)"'

if [[ '<string tag="answer_yes" value="Yes"/>' =~ $regex ]] ; then
    echo "${BASH_REMATCH[1]}" ;
fi

值-V21 / styles.xml 

<item name="android:windowTranslucentStatus">true</item>

使用已经处理fitsSystemWindows参数的CoordinatorLayout / DrawerLayout或创建自己的布局，如下所示：

<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@color/colorPrimaryDark</item>

main_activity.xml 

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();

对于那些希望在KitKat以及更高版本上使用完全透明的状态栏和导航栏的人，将windowTranslucentNavigation与@Machado的Lollipop答案一起使用并防止样式分开会产生小的冲突

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>
</style>

styles.xml （v21） 

<style name="LockScreenStyle" parent="@android:style/Theme.Wallpaper.NoTitleBar">
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
</style>

MyClass.java 

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) {

您还可以将colorPrimary和colorPrimaryDark的alpha更改为00，然后将其添加到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"

您可以使用此kotlin扩展功能将状态栏设置为完全透明（在 API 23 + 上，在{strong> API 23 + 上可用的View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR标志），以及导航栏（在 API 27 + 上，在{strong> API 27 + 上具有View.SYSTEM_UI_FLAG_LIGHT_NAVIGATION_BAR标志），否则它将在 API上使用systemUiScrim颜色21岁以上 

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

这适用于像我这样的 Nativescript + Angular 新手。我从 NTS marketplace 上的一个空白模板开始。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），并且导航栏（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/模块上不透明。如果一切都按照 NTS 设置的协议完成，您应该有一个类似于此的 main.ts（我的解决方案的先决条件） enter image description here

我将我的作品分成两部分，首先是顶部，然后是底部。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);
    }
}

});

然后为了向导航栏添加透明度，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">

    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:windowTranslucentNavigation">false</item>
</style>

<style name="AppTheme" parent="AppThemeBase"></style>

    <item name="theme">@color/transparent</item>
    <item name="popupTheme">@color/transparent</item>
</style>

<style name="NativeScriptToolbarStyle" parent="NativeScriptToolbarStyleBase"></style>
