Question

当我们更改Android手机方向时，我们收到以下错误。目前在android v 5和4.4.4中测试这个。我们的应用程序被锁定为肖像。因此，如果我们将手机转为横向模式，视图将不会更改，但会保持纵向模式。

当我们将手机方向更改为横向时，会抛出此异常并且应用程序崩溃。这将永远无法复制。但是，一旦在10或15次，应用程序崩溃与以下错误。即使它是随机的，也可以不断复制。如果我们在任何特定时间扭动手机但可能不确定。我经常在登录或退出操作期间扭动手机，这需要几秒钟才能完成这些操作。

不会从特定活动或代码段抛出此异常。正如我在帖子中提到的那样，当我在10或15次随机的任何视图上改变手机方向时会抛出这种情况。但是无法不断复制。

以下是完整的堆栈跟踪。

您可以覆盖活动中的onConfigurationChanged，并在每次更改方向时更新阵列。

diff(x-y) <= 1

您还需要将android：configChanges添加到您的活动中：

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        // Update your array here
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
        // Update your array here
    }
}

当方向更改时，此代码将停止重新启动您的活动。但是这可能不起作用，因为我不知道你的代码是什么样的。
