Android完全透明的状态栏?

我搜索了文档，但只找到了这个: 链接。这是用来使酒吧半透明?我想做的是使状态栏完全透明(如下图所示)，并使它向后兼容APK<19:

我的styles.xml:

<resources xmlns:tools="http://schemas.android.com/tools">

  <style name="AppTheme" parent="Theme.AppCompat.Light">
  <item name="android:actionBarStyle">@style/ThemeActionBar</item>
  <item name="android:windowActionBarOverlay">true</item>
  <!-- Support library compatibility -->
  <item name="actionBarStyle">@style/ThemeActionBar</item>
  <item name="windowActionBarOverlay">true</item>
  </style>

  <style name="ThemeActionBar" parent="Widget.AppCompat.Light.ActionBar.Solid">
  <item name="android:background"> @null </item>
  <!-- Support library compatibility -->
  <item name="background">@null</item>
  <item name="android:displayOptions"> showHome | useLogo</item>
  <item name="displayOptions">showHome|useLogo</item>

  </style>

</resources>

我能做的是:

2022年最优雅的方案:

private fun hideStatusBar() {
    val windowInsetsController = ViewCompat.getWindowInsetsController(window.decorView) ?: return
    windowInsetsController.hide(WindowInsetsCompat.Type.statusBars())
}

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:)

在setContentView()之前将这些行添加到您的活动中

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
    Window w = getWindow();
    w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}

添加这2行到你的AppTheme

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

最后一件事你的思想sdkversion必须是19

minSdkVersion 19
2019-03-29 12:52:11

下面的代码将创建一个完全透明的状态栏:

package com.demo;

import android.app.Activity;
import android.graphics.Color;
import android.os.Build;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

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

        if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
            setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
        }
        if (Build.VERSION.SDK_INT >= 19) {
            getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
        }
        if (Build.VERSION.SDK_INT >= 21) {
            setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
            getWindow().setStatusBarColor(Color.TRANSPARENT);
        }
    }

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

用于谷歌的最后一次更新。这是我的代码。这将是透明的状态栏和导航栏: 把你的主题改为:

 <style name="Theme.Pink" 
 parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <!-- Primary brand color. -->
    <item name="colorPrimary">@color/pink_primary</item>
    <item name="colorPrimaryVariant">@color/pink_dark</item>
    <item name="colorOnPrimary">@color/black</item>
    <!-- Secondary brand color. -->
    <item name="colorSecondary">@color/pink_light</item>
    <item name="colorSecondaryVariant">@color/pink_primary</item>
    <item name="colorOnSecondary">@color/black</item>
    <item name="android:textColor">?attr/colorOnPrimary</item>
    <!-- Status bar color. -->
    <!-- Customize your theme here. -->
 //transparent statusbar
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:windowIsTranslucent">true</item>
//transparent navigationbar
    <item name="android:windowTranslucentNavigation">true</item> 
 </style>

然后在layout (file xml)中:添加2个属性point_top和point_bottom来确定应用程序其他组件的边距值的位置:

    <androidx.constraintlayout.widget.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg_activity">

    <TextView
        android:id="@+id/point_top"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    

    <TextView
        android:id="@+id/point_bottom"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />
   
       <.....>

   </androidx.constraintlayout.widget.ConstraintLayout>

然后在baseActivity或yourActivity中:在onCreate中添加以下代码:

 override fun onCreate(savedInstanceState: Bundle?) {
   
    super.onCreate(savedInstanceState)
    binding = setLayout()
    //set inset for view
    ViewCompat.setOnApplyWindowInsetsListener(binding.root) { _, insets ->
        val paramsTop =
            findViewById<TextView>(R.id.point_top).layoutParams as MarginLayoutParams
        paramsTop.setMargins(0, insets.getInsets(WindowInsetsCompat.Type.systemBars()).top, 0, 0)
        findViewById<TextView>(R.id.point_top).layoutParams = paramsTop
        val paramsBottom =
            findViewById<TextView>(R.id.point_bottom).layoutParams as MarginLayoutParams
        paramsBottom.setMargins(0, 0, 0, insets.getInsets(WindowInsetsCompat.Type.systemBars()).bottom)
        findViewById<TextView>(R.id.point_bottom).layoutParams = paramsBottom
        insets.consumeSystemWindowInsets()

    }

    setContentView(binding.root)
}

希望这对大家有所帮助。

对于API > 23日/夜支持，您可以使用下面的扩展。要理解的重要部分是android:fitsSystemWindows="true"使用填充来在嵌入内移动(就像你会用一个工具栏)。因此，将它放在根布局中是没有意义的(除了DrawerLayout, CoordinatorLayout，…它们使用自己的实现)。

<style name="Theme.YourApp.DayNight" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    ...
    <item name="android:windowLightStatusBar">@bool/isDayMode</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>

<androidx.constraintlayout.widget.ConstraintLayout
    ...>

    <com.google.android.material.appbar.MaterialToolbar
        ...
        android:fitsSystemWindows="true">

</androidx.constraintlayout.widget.ConstraintLayout

fun Activity.transparentStatusBar() {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.R) {
        window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
    } else {
        window.setDecorFitsSystemWindows(false)
    }
}

然后像这样称呼它:

class YourActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ...
        transparentStatusBar()
    }
}

看看克里斯·巴内斯的这些幻灯片:成为窗户安装大师

编辑:如果你对导航栏后面的浮动内容有问题，请使用

// using Insetter
binding.yourViewHere.applySystemWindowInsetsToPadding(bottom = true)
