沉浸式,全屏状态栏

1:全屏模式:

没有状态栏,就style里面设置就行了

    <style name="AppTheme.FullBar" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@android:color/transparent</item>
        <item name="android:windowBackground">@color/white</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowIsTranslucent">true</item>
    </style>

2:沉浸式1:

没有有状态栏,但是状态栏上的字显示着,代码有点多

style代码:

<style name="WhiteAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="windowNoTitle">true</item>
        <item name="android:windowActionBar">@null</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/transparent</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowBackground">@color/white</item>
        <item name="android:windowLightStatusBar">true</item>
        <item name="android:screenOrientation">portrait</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="actionMenuTextColor">@color/colorPrimary</item>
    </style>

然后在setContentView前设置一句

window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)

样式:

有状态栏,有显示文字

style代码:

<style name="WhiteAppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="windowNoTitle">true</item>
        <item name="android:windowActionBar">@null</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/transparent</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowBackground">@color/white</item>
        <item name="android:windowLightStatusBar">true</item>
        <item name="android:screenOrientation">portrait</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name="actionMenuTextColor">@color/colorPrimary</item>
    </style>

其实和上面那个的style一样的,只是状态栏的颜色是这里面的android:windowBackground参数,只是少了在setContentView前设置的一句代码

样式:

动态设置状态栏颜色

        window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window.statusBarColor = ContextCompat.getColor(this , color)//color是@color/white这种的

动态设置状态栏字体颜色

/**
     * 改变状态栏字体颜色,白色和黑色两种
     * @param update
     * true:深色,false:浅色
     */
    protected fun changeStatusBarTxtColor(update : Boolean) {
        var originFlag = window.decorView.systemUiVisibility
        if (update) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) window.decorView.systemUiVisibility = originFlag or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
        } else {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
        }
        window.decorView.findViewById<FrameLayout>(android.R.id.content).setPadding(0 , 0 , 0 , 0)
    }
