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:
适用于Android KitKat和以上(对于那些想要透明的状态栏和不操作导航栏，因为所有这些答案将透明导航栏太!)
最简单的实现方法:
把这3行代码放在styles.xml (v19) ->中，如果你不知道如何有这个(v19)，只需要把它们写在默认的styles.xml中，然后使用alt+enter自动创建它:
<item name="android:windowFullscreen">false</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:fitsSystemWindows">false</item>
现在，转到MainActivity类，把这个方法从类的onCreate中放出来:
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);
}
然后把这段代码放到Activity的onCreate方法中:
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);
}
//make fully Android Transparent Status bar
if (Build.VERSION.SDK_INT >= 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
getWindow().setStatusBarColor(Color.TRANSPARENT);
}
就是这样!
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。
你所需要做的就是在你的主题中设置这些属性:
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
你的活动/容器布局，你希望有一个透明的状态栏需要这个属性集:
android:fitsSystemWindows="true"
这通常是不可能执行这肯定在预kitkat，看起来你可以这样做，但一些奇怪的代码使它如此。
编辑:我推荐这个lib: https://github.com/jgilfelt/SystemBarTint为许多前棒棒糖状态栏颜色控制。
经过深思熟虑，我了解到完全禁用状态栏和棒棒糖导航栏上的半透明或任何颜色的答案是在窗口上设置这个标志:
// In Activity's onCreate() for instance
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);
}
没有其他主题是必要的，它产生如下内容:
