我刚在这里找到的

因为它已经经过了6年，默认的minSDKAPI是21(棒棒糖)*CMIIW。下面是我总结透明状态栏并且不与导航按钮重叠的方法:

fun setStatusBarTransparent(activity: Activity, view: View) {
    activity.apply {
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.statusBarColor = ContextCompat.getColor(this, R.color.transparent)
        WindowCompat.setDecorFitsSystemWindows(window, false)
        ViewCompat.setOnApplyWindowInsetsListener(view) { root, windowInset ->
            val inset = windowInset.getInsets(WindowInsetsCompat.Type.systemBars())
            root.updateLayoutParams<ViewGroup.MarginLayoutParams> {
                leftMargin = inset.left
                bottomMargin = inset.bottom
                rightMargin = inset.right
                topMargin = 0
            }
            WindowInsetsCompat.CONSUMED
        }
    }
}

要再次显示状态栏只需要做一些更改:

fun setStatusBarShown(activity: Activity, view: View) {
    activity.apply {
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.statusBarColor = ContextCompat.getColor(this, R.color.transparent)
        WindowCompat.setDecorFitsSystemWindows(window, false)
        ViewCompat.setOnApplyWindowInsetsListener(view) { root, windowInset ->
            val inset = windowInset.getInsets(WindowInsetsCompat.Type.systemBars())
            val inset1 = windowInset.getInsets(WindowInsetsCompat.Type.statusBars())
            root.updateLayoutParams<ViewGroup.MarginLayoutParams> {
                leftMargin = inset.left
                bottomMargin = inset.bottom
                topMargin = inset1.top
                rightMargin = inset.right
            }
            WindowInsetsCompat.CONSUMED
        }
    }
}

我把这个函数放在对象类称为UiUtils，所以当我在我的活动调用该函数(我使用视图绑定太)。它看起来是这样的:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    ...
    UiUtils.setStatusBarTransparent(this, bind.root)
    ...
}

希望我的回答能帮助到你们:)

我发现摆弄styles.xml和activity太麻烦了，因此创建了一个通用的实用工具方法，它有以下选项集

Java

Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
window.setStatusBarColor(Color.TRANSPARENT);

Kotlin DSL

activity.window.apply {
    clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
    addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
    decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    statusBarColor = Color.TRANSPARENT
}

这就是实现透明状态栏所需要的全部内容。希望这能有所帮助。

我在调查这个图书馆的时候找到了答案: https://github.com/laobie/StatusBarUtil

因此，您需要将以下代码添加到您的活动

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
    window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION)
    window.statusBarColor = Color.TRANSPARENT
} else {
    window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
}

它只是移除statusBar的颜色!

window?.decorView?.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
window?.statusBarColor = Color.TRANSPARENT

这招对我管用，希望对你也管用

只需将这行代码添加到你的主java文件中:

getWindow().setFlags(
    WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
    WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
);

完全透明的状态栏和导航栏

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    transparentStatusAndNavigation();
}


private void transparentStatusAndNavigation() {
    //make full transparent statusBar
    if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
        setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, true);
    }
    if (Build.VERSION.SDK_INT >= 19) {
        getWindow().getDecorView().setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
        );
    }
    if (Build.VERSION.SDK_INT >= 21) {
        setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
                | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, false);
        getWindow().setStatusBarColor(Color.TRANSPARENT);
        getWindow().setNavigationBarColor(Color.TRANSPARENT);
    }
}

private void setWindowFlag(final int bits, boolean on) {
    Window win = getWindow();
    WindowManager.LayoutParams winParams = win.getAttributes();
    if (on) {
        winParams.flags |= bits;
    } else {
        winParams.flags &= ~bits;
    }
    win.setAttributes(winParams);
}
