我有一个在纵向和横向中使用两种布局的应用程序。要在初始加载时从Web加载内容，我使用AsyncTask和进度条。
我查了this。由于我有两个布局，这不是解决方案。
以下是例外情况。

是否有一种锁定旋转变化的方法，直到应用程序自行加载？
或者其他想法？
提前致谢。
答案 0 :(得分：1)
切换方向时，Android会创建一个新视图。您可能正在崩溃，因为您的后台线程正在尝试更改旧的状态。 （它可能也有问题，因为你的后台线程不在UI线程上）。 这些是解决方案：
How to handle screen orientation change when progress dialog and background thread active?
答案 1 :(得分：0)
我在progressDialog.dismiss()方法中调用onDestroy()。
在方向更改期间，活动将重新开始。所以在重启之前我们必须销毁当前的progressDialog。这样就可以了。 ：d
答案 2 :(得分：-1)
您正在获取WindowLeak Exception，当任何dialog / progressBar使用由于方向更改而丢失的上下文和上下文引用的引用时，会发生此异常。
因此，请在清单文件中为所有活动标记添加以下代码。
android:configChanges="orientation|keyboard"
示例：
<activity
android:name=".InviteActivity" android:configChanges="orientation|keyboard"/>
并在活动中使用以下代码
@Override
public void onConfigurationChanged(Configuration newConfig)
{
setContentView(R.layout.YOUR_LAYOUT);
super.onConfigurationChanged(newConfig);
}
答案 3 :(得分：-1)
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);
