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:
这个解决方案是为那些谁想要一个完全透明的状态栏和导航栏不受影响。令人难以置信的是，这听起来如此简单，以至于导致包括我在内的不止一个人头疼。
这就是我所说的最终结果
结果
我们只需要两个函数，我建议在我们的活动的OnCreate中调用，第一个是setStatusBar()，这是负责使透明的同一个。
private fun setStatusBar() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.apply {
clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
decorView.systemUiVisibility =
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
} else {
decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}
statusBarColor = Color.TRANSPARENT
}
}
第二个函数setedges()负责设置与顶部受限的视图相对应的边距，否则，这些视图将在StatusBar下面被看到。
private fun setMargins() {
ViewCompat.setOnApplyWindowInsetsListener(
findViewById(R.id.your_parent_view)
) { _, insets ->
val view = findViewById<FrameLayout>(R.id.your_child_view)
val params = view.layoutParams as ViewGroup.MarginLayoutParams
params.setMargins(
0,
insets.systemWindowInsetTop,
0,
0
)
view.layoutParams = params
insets.consumeSystemWindowInsets()
}
}
最终代码看起来像这样:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.your_layout))
setStatusBar()
setMargins()
}
private fun setStatusBar() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.apply {
clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
decorView.systemUiVisibility =
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
} else {
decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}
statusBarColor = Color.TRANSPARENT
}
}
private fun setMargins() {
ViewCompat.setOnApplyWindowInsetsListener(
findViewById(R.id.your_parent_view)
) { _, insets ->
val view = findViewById<FrameLayout>(R.id.your_child_view)
val params = view.layoutParams as ViewGroup.MarginLayoutParams
params.setMargins(
0,
insets.systemWindowInsetTop,
0,
0
)
view.layoutParams = params
insets.consumeSystemWindowInsets()
}
}
你可以在下面的文章中找到更详细的解释
我还留下了一个测试项目，这些概念在其中发挥作用。
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。
