StatusBarHelper

StatusBar 工具类

object StatusBarHelper {
   /**
     * 内容显示在状态栏下面（LAYOUT_FULLSCREEN） > 6.0

     */
  fun fitSystemBar(activity: Activity, light: Boolean = true) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) return

    val decorView = window.decorView
    var visibility = decorView.systemUiVisibility
    visibility = visibility or
    View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or
    View.SYSTEM_UI_FLAG_LAYOUT_STABLE
    visibility = if (light) {
      visibility or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
    } else {
      visibility and View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR.inv()
    }
    decorView.systemUiVisibility = visibility

    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
    window.statusBarColor = Color.TRANSPARENT
  }

   /**
     * 调整状态栏文字、图标颜色 > 6.0
     * true:白底黑字,false:黑底白字
     */
  fun lightStatusBar(activity: Activity, light: Boolean = true) {
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) return
    var window: Window = activity.window
    var visibility = window.decorView.systemUiVisibility
    visibility = if (light) {
      visibility or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR

  // 获取状态栏高度
  fun getStatusBarHeight(activity: Activity): Int {
    var result: Int = 0
    var resId = activity.resources.getIdentifier("status_bar_height", "dimen", "android")
    if (resId > 0) result = activity.resources.getDimensionPixelOffset(resId)
    return result
  }
}

默认statusbar 高度 24dp（不同版本可能不一样）。如果设置内容显示在状态栏下面，需要在相应的布局设置android:fitsSystemWindows="true"，系统会为该布局自动添加一个statusbar高度的topPadding。

SystemBar隐藏/显示模式

var options: Int = View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                    | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN // make content behind status bar
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE  // keep layout stable
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide navigation bar
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION // make content behind navigation bar
                    | View.SYSTEM_UI_FLAG_IMMERSIVE // immersive mode
