Question

我想保存视图“ArrayList”的ArrayList的内容。我重写方法“onSaveInstanceState”，如下面的代码所示，但在运行时我收到下面发布的logcat错误。请让他们知道如何在捆绑中设置View对象列表

码：

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    Log.w(TAG, "onSaveInstanceState");

    if (this.mListViews != null && this.mListViews.size() > 0) {
        outState.putSerializable(KEY_LIST_OF_VIEWS, this.mListViews);
   }
  }

logcat的

您不应该将视图保存在savedInstanceState中。你应该只保存listview的值。它将自动创建视图
