一个不报错但运行失败的问题

VictorIsildur 2011-08-29 11:03:25

这里我陈列一下简版代码：



public class IsiCamera extends Activity {

  ...

  public void onCreate(){

    final CameraSurfaceView cameraView = ...;

    setOnClickListener(){

      cameraView.takeAPicture()....

    }

  }

  ...

}

程序正常运行

现在由于setOnClickListener()方法过于长，我把它外包出去，记作



private void setListener() {

    setOnClickListener(){

      cameraView.takeAPicture()....

    }

}

因为setOnClickListener()里用到cameraView对象，把cameraView实例化的语句放到了public void onCreate()的外面，使之成为Member data.
总的代码如下：



public class IsiCamera extends Activity {

  ...

  final CameraSurfaceView cameraView = ...;

  

  public void onCreate(){

    setListener();    

  }



  private void setListener() {

    setOnClickListener(){

      cameraView.takeAPicture()....

    }

}

eclipse没有报错，但程序跑不起来了，求解答。

我不知道log什么时候产生的，8-30号9:40我又run了一次，但最新的log还是8-29号的。不知道是不是针对这个版本程序的。
