推荐答案

如果要强制你的的TextView 保存其状态必须添加<一href="http://developer.android.com/reference/android/widget/TextView.html#attr_android%3afreezesText"><$c$c>freezesText属性：

If you want to force your TextView to save its state you must add freezesText attribute:

<TextView 
     ... 
     android:freezesText="true" />

从技术文档的<一个href="http://developer.android.com/reference/android/widget/TextView.html#attr_android%3afreezesText"><$c$c>freezesText

如果设置，文本视图将包括其冻结的冰柱除了元数据的内部当前的完整文本，如当前的光标位置。默认情况下，这是禁用的;当一个文本视图的内容未存储在持久性的地方也可以是有用的诸如内容提供商

If set, the text view will include its current complete text inside of its frozen icicle in addition to meta-data such as the current cursor position. By default this is disabled; it can be useful when the contents of a text view is not stored in a persistent place such as a content provider
