以下是我的代码(来自 MainActivity.java):

public void onWindowFocusChanged(boolean isFocused)
{

    super.onWindowFocusChanged(isFocused);
    long tempTime = 0;
    if(!isFocused)
    {
        try
        {
            FileOutputStream  fos = this.openFileOutput("timekeeper", Context.MODE_PRIVATE);
            ObjectOutputStream  oos = new ObjectOutputStream (fos);
            oos.writeObject(AnimationUtils.currentAnimationTimeMillis());
            oos.close();
        }
        catch (IOException e)
        {
            //Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    }
    else
    {
        try
        {
            FileInputStream  fis = this.openFileInput("timekeeper");
            ObjectInputStream  ois = new ObjectInputStream (fis);
            tempTime = ois.readLong();
            ois.close();
        }
        catch(Exception e)
        {
            //Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
        }
        if((tempTime != 0))
        {

        }
    }
}

我检查了代码,它总是发布 Toats(如果不是 //'d :))。什么不见​​了?这是在 android 活动中存储/调用信息的正确方法吗?除了上面的代码,我没有在其他任何地方声明该文件。我应该有吗?

如果我遗漏了重要信息,请告诉我...

谢谢!
