最佳答案
当您旋转手机时, Activity 会被破坏并重新创建。所以变量被重新初始化。这就是为什么数据不显示
的原因。你可以通过阻止 Activity onRotation 的破坏来克服这个问题。要实现这一点,请将其放入您的 list 中:
<activity android:name="FriendPickerActivity"
android:label="@string/app_name"
android:configChanges="orientation"/>
我指向 android:configChanges="orientation"
或者你可以在你的activity中使用onSaveInstanceState()
和onRestoreInstanceState()
