Android: couldn't save which view has focus because the focused view ### has no id

在把pro.android的包放到ios工程项目之后，编译文件，出现了上面的这个问题。

我使用了下面方案一的解决办法解决了这个问题。

可能引起原因有两种，对应解决方法如下：

解决方案二：

What probably happened is that you created a thread in the surfaceCreated() method but didn’t stop it or get rid of it in the surfaceDestroy() method.

When you didn’t give a theme for the preferences, it took over the whole screen and your old surface was destroyed. But when you specified a dialog-like theme, the old surface was still there because it was visible underneath the preferences.

public void surfaceCreated(SurfaceHolder holder)
{
if (_thread == null || _thread.getState() == Thread.State.TERMINATED)
{
_thread = new TutorialThread(getHolder(), this);
_thread.setRunning(true);
_thread.start();
}
else
{
_thread.setRunning(true);
_thread.start();
}
}

This solved the problem for me, a thread’s start method cannot be called twice, so I had to reallocate…
