android– 如何在更改方向时保持ViewFlipper中的当前视图

概述有没有什么好方法可以在ViewFlipper中保持当前视图,而sill能够加载layout-port文件夹？也许使用onRetainNonConfigurationInstance()？如果是这样,我将如何实施呢？我尝试了一些推杆解决方案：android:configChanges="orientation|keyboardHidden"在清单中.问题是Android然后忽略我的

有没有什么好方法可以在VIEwFlipper中保持当前视图,而sill能够加载layout-port文件夹？也许使用onRetainNonConfigurationInstance()？如果是这样,我将如何实施呢？我尝试了一些推杆解决方案：

androID:configChanges="orIEntation|keyboardHIDden"

在清单中.

问题是AndroID然后忽略我的布局端口文件夹,它重新排列输入字段和按钮.

–Update–

这是我添加了hooked82代码的代码.我添加了抛出错误的部分：

这是发生错误的地方的Logcat输出：

我希望这有帮助.

解决方法:

尝试通过覆盖onSaveInstanceState来保存屏幕方向更改时在VIEwFlipper中保存的选项卡

@OverrIDepublic voID onSaveInstanceState(Bundle savedInstanceState) {    int position = flipper.getdisplayedChild();    savedInstanceState.putInt("TAB_NUMBER", position);}

然后在你的onCreate中,尝试以下方法

@OverrIDepublic voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    if (savedInstanceState != null) {        int flipperposition = savedInstanceState.getInt("TAB_NUMBER");        flipper.setdisplayedChild(flipperposition);    }}

确保只在初始化了鳍状肢之后才在鳍状肢上调用setdisplayedChild()方法,例如,通过执行某些 *** 作

flipper =(VIEwFlipper)findVIEwByID(R.ID.flipper);

在你的onCreate()方法中.不这样做可能会导致崩溃.
