[Android] 修复头条屏幕适配方案导致的两次获取尺寸不一问题

object DisplayMetricsUtil {
  @JvmStatic
  fun applyRealMetrics(activity: Activity) {
    //获取真实dp参数
    val dm = DisplayMetrics()
    activity.windowManager.apply {
      defaultDisplay.getRealMetrics(dm)
    }
    //应用到activity
    val displayMetrics = activity.resources.displayMetrics
    displayMetrics.density = dm.density
    displayMetrics.scaledDensity = dm.scaledDensity
    displayMetrics.widthPixels = dm.widthPixels
    displayMetrics.heightPixels = dm.heightPixels
    displayMetrics.xdpi = dm.xdpi
    displayMetrics.ydpi = dm.ydpi
    displayMetrics.densityDpi = dm.densityDpi
  }
