Attempt to invoke virtual method 'void android.app.Dialog.setOnKeyListener(android.content.DialogInterface$OnKeyListener)' on a null object reference 以下是测试代码： handler.post { meetDialog?.doDismiss() meetDialog = MessageDialog.build(ActivityUtils.topActivity as AppCompatActivity) .setTitle("test") .setMessage(null) .setCancelable(false) .setOkButton(getString(R.string.ok)) { , -> false } meetDialog?.show() } handler.post { meetDialog?.doDismiss() meetDialog = MessageDialog.build(ActivityUtils.topActivity as AppCompatActivity) .setTitle("test1") .setMessage(null) .setCancelable(false) .setOkButton(getString(R.string.ok)) { , -> false } meetDialog?.show() }
