检测 Android Wear screen 是否有下巴(又名漏气轮胎)

Detect if Android Wear screen has chin (aka flat tire)

在开发AndroidWear watch face的时候,怎么检测屏幕是不是圆的,有没有下巴(又名flat tire band),比如Moto 360? 我试过了onSurfaceChanged,但是那里的宽度和高度是一样的。

我在有下巴的模拟器上试过了,还是检测不到下巴,是模拟器问题还是我的代码问题?:

@Override
void onApplyWindowInsets(WindowInsets insets) {
    super.onApplyWindowInsets(insets);
    // check if MOTO360 or other Chin layouts
    Log.d(TAG,String.format("isRound : %s, BottomInset :%d",insets.isRound()?"YES":"NO",insets.getStableInsetBottom()));
    // LOG OUTPUT : isRound : YES, BottomInset :0
    if (insets.isRound() && insets.getStableInsetBottom() > 0)
        ClockPaintingRoutines.flat_display_mode=true;
 }

我正在使用:

insets.getSystemWindowInsetBottom() > 0

这在模拟器上对我有用,但我没有真正的设备来测试它。

//Kotlin

// height
val height = resources.displayMetrics.heightPixels
// width
val width = resources.displayMetrics.widthPixels

// is round?
val screenForm = resources.configuration.isScreenRound

// if true
val form = if (screenForm) {
   if (height != width)
      "Round chin"
   else
      "Round"
} else {
   "Square"
}
