我有一个应用程序，它在纵向和横向中使用两种布局。为了在初始加载时从 web 加载内容，我使用了 AsyncTask 和进度条。

我检查了这个。由于我有两种布局，这不是解决方案。

下面给出了例外情况。

有没有一种方法可以锁定旋转变化，直到应用程序自行加载？

或者和其他想法？

提前致谢。

当您切换方向时，Android 将创建一个新视图。您可能会崩溃，因为您的后台线程正在尝试更改旧线程的状态。（它也可能有问题，因为您的后台线程不在 UI 线程上）。这些是解决方案：

进度对话框和后台线程处于活动状态时如何处理屏幕方向更改？

progressDialog.dismiss()我在方法中调用了onDestroy()。

在方向改变期间，活动重新开始。所以在重启之前我们必须销毁当前的progressDialog。这可以解决问题。:D

You are getting WindowLeak Exception, this exception occur when any dialog/progressBar uses the reference of context and context reference lost due to orientation change.

So put below code for all activity tag in manifest file.

android:configChanges="orientation|keyboard"

example: 

<activity
            android:name=".InviteActivity" android:configChanges="orientation|keyboard"/>

and use below code in activity

 @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        setContentView(R.layout.YOUR_LAYOUT);
        super.onConfigurationChanged(newConfig);
    }

我遇到了同样的问题并解决了这个问题，我在开始同步之前锁定了方向并在同步后将其设置回来：

// before
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);

// after synchronisation: 
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
