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

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：

解决方案一：

<application   
        
        android:icon="@drawable/icon" android:label="@string/app_name" >   
        
        <activity   
        
            android:label="@string/app_name"
        
           android:configChanges="orientation|keyboardHidden|keyboard|screenLayout"
        
            android:name=".Main" >   
        
            <intent-filter >   
        
                <action android:name="android.intent.action.MAIN" />   
        
                <category android:name="android.intent.category.LAUNCHER" />   
        
            </intent-filter>   
        
        </activity>   
        
    </application>

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…
