【備忘録】Androidのステータスバーにグラデーションを指定する

Posted at

画面一面グラデーションなどをやると結構綺麗でした。

Activity.kt

class Activity : AppCompatActivity() {

   override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        //好きなグラデーションの向き
        val orientation = GradientDrawable.Orientation.BR_TL
        //好きなグラデーションの色
        val color1 = Color.parseColor("#e5a323")
        val color2 = Color.parseColor("#c4972f")
        val color3 = Color.parseColor("#ac6b25")
        //決めたグラデーションを色が変化する順番に並べる(二色でも良い)
        val colors: IntArray = intArrayOf(color1,color2,color3)
        
        val gradientDrawable = GradientDrawable(orientation,colors)
        
        //ステータスバーの背景を透明にする
     window?.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        window?.statusBarColor = Color.TRANSPARENT
        window?.navigationBarColor = Color.TRANSPARENT
        window?.setBackgroundDrawable(gradientDrawable)
        
        //レイアウトファイルを読み込む
        setContentView(R.layout.activity)
        
        
        

   }
