页面里面返回键会触发显示是否操作的弹窗，发现有一定的几率弹窗显示后会自动关闭 about xpopup

经我多次测试，如果这个弹窗显示是由系统的back键触发显示的就会偶发这种现象下面我会贴出代码和日志：
class MainActivity : AppCompatActivity() {
lateinit var textView: TextView

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    textView = findViewById<TextView>(R.id.textView);
    textView.setOnClickListener {
        testDialog("onClickAction")
    }
}

override fun onKeyDown(keyCode: Int, event: KeyEvent?): Boolean {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        testDialog("onKeyDownBackAction")
        return true
    }
    return super.onKeyDown(keyCode, event)
}

private fun testDialog(action: String) {
    val clickTime = Date().time
    val xPopup = XPopup.Builder(this).isDestroyOnDismiss(true)
        .setPopupCallback(object : SimpleCallback() {
            override fun onDismiss(popupView: BasePopupView?) {
                val dismissTime = Date().time
                Log.e(action, "onDismiss: ${dismissTime - clickTime}")
            }
        }).asConfirm("Confirm", "Are you sure to exit?") {

        }.setConfirmText("OK").setCancelText("Cancel")
    xPopup.show()
    textView.postDelayed({
        if (xPopup.isShow) {
            xPopup.dismiss()
        }
    }, 500)
}

}

可以看到keydownbackaction日志从显示到消失的时间很短，那么也就是触发自动关闭了
