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

Question

在我的应用程序中，我使用此方法检测屏幕上的键盘。它在api 28+上运行得很好，但一旦我低于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？

Answer 1

显然，键盘外观支持不支持api<28，所以在getInsets (ime ())的向后兼容性发布之前，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？
