android - 致命异常：NoSuchMethodError：没有虚拟方法插入（IIII）Landroid/view/WindowInsets

问题描述

在我的应用程序中，我使用这种方法来检测屏幕上的键盘。它在 api 28+ 上完美运行但是一旦我低于 api 28，它就会开始导致崩溃。

  private fun isKeyboardOpen() {
   window?.decorView?.setOnApplyWindowInsetsListener { v, insets ->
       val systemWindowInsets = insets.inset(0,0,0,200)
        imeVisible = ViewCompat.getRootWindowInsets(requireView())?.getInsets(ime())
        if(imeVisible != null){
            if(imeVisible?.bottom!! > 0){
                ivWeatherIcon1.visibility = View.INVISIBLE
            } else {
                ivWeatherIcon1.visibility = View.VISIBLE
            }
        }
       systemWindowInsets
    }
}

有没有办法让这个方法回到 api 23？

解决方案

显然，键盘外观支持还不支持 api <28，所以在getInsets (ime ())发布向后兼容性之前 - 您可以使用以下代码：

private fun isKeyboardOpen() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            // your code above
        } else {
            // code from source below
        }
    }

如何在 Android 中检查软件键盘的可见性？
