在Android中的OrientationEventListener中获取横向模式下的高度和宽度

Question

我想在设备方向改变时获取屏幕高度和宽度，并且我使用 OrientationEventListener 而不是 onConfigurationChanged() 方法。

对于以下代码：

1）方向事件监听器

mOrientationListener = object : OrientationEventListener (context, SensorManager.SENSOR_DELAY_UI)
{
override fun onOrientationChanged (orientation: Int)
{
    if (gTemp == false) {
        
        gTemp = true
    
    } else if (orientation == 0 || orientation == 180) {

        Log.d ("orientation", "Orientation: Portrait")
        
        width = TWOSScreenAspectsAndroid.GetScreenHeight ()
        height = TWOSScreenAspectsAndroid.GetScreenWidth ()
         
        // call cpp function 
        OrientationChanged (pInstructionSetIndex, width, height)


    } else if (orientation == 90 || orientation == 270) {

        Log.d ("orientation", "Orientation: LandScape")
    
        width = TWOSScreenAspectsAndroid.GetScreenHeight ()
        height = TWOSScreenAspectsAndroid.GetScreenWidth ()
        
        // call cpp function
        OrientationChanged (pInstructionSetIndex, width, height)
    }
}
}

if (mOrientationListener.canDetectOrientation ()) {

mOrientationListener.enable ()
}

2)TWOSScreenAspectsAndroid.GetScreenHeight()

@JvmStatic
public fun GetScreenHeight (): Int
{
    val metric: WindowMetrics
    val insets: Insets                         // An Insets instance holds four integer offsets which describe changes to the four edges of a Rectangle.
    val displayMetrics: DisplayMetrics
    val height: Int
    val insetsHeight: Int
    val context: Context?
     val activity: Activity

context = TWProcessStates.GetMainActivityContext ()

activity = context as Activity

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {

    // Code for API level 30 and higher

    metric = activity.windowManager.currentWindowMetrics
    insets = activity.windowManager.currentWindowMetrics.windowInsets.getInsetsIgnoringVisibility (WindowInsets.Type.navigationBars() or WindowInsets.Type.displayCutout ())

    insetsHeight = insets.top + insets.bottom

    Log.d ("orientation_height", "${insets.right}, ${insets.left}, ${insets.top}, ${insets.bottom}")

    height = metric.bounds.height () - insetsHeight

} else {

    // Code for API level 29 and lower

    displayMetrics = DisplayMetrics ()
    activity.windowManager.defaultDisplay.getMetrics (displayMetrics)

    height = displayMetrics.heightPixels
}

Log.d ("orientation_height", "Inside TWOSScreenAspectsAndroid::GetScreenHeight Height: $height")
return height
}

当方向为横向时，我得到纵向模式的高度和宽度，反之亦然，如下面的日志所示：

如何解决这个问题？

Answer 1

您错误地将宽度分配给高度函数。你写了这个：

width = TWOSScreenAspectsAndroid.GetScreenHeight ()

应该是：

height = TWOSScreenAspectsAndroid.GetScreenHeight ()

反之亦然
