我需要在塔霍斯特的每一条表格中提供“观点”。 然后,它应当涵盖一切,包括表格。 我尝试在TabHost和TabWidget进行即时调查,但每次我尝试利用发现的“GreId”作出归属决定时,我都会给我Null Pointer。 任何想法?

The solution to this was put the widget in the main tab activity (TabActivity). Then, I created a method such as:
public ViewFlipper getWidget(){
return this.mWidget;
}
然后,我得以从任何儿童活动中叫它。
我强烈建议任何读书的人都遵循docs和其他用户的建议:不使用 Tab。 还有一些比平权更好的解决办法。
