Android 安卓文本视图：取消删除以前被删除的文本

我在互联网上搜索了一下，发现要取消删除被删除的文本，我需要使用以下代码：

tv.setPaintFlags tv.getPaintFlags&~Paint.STRIKE\u THRU\u TEXT\u FLAG

其中tv代表某个TextView变量。这对我来说根本不管用。我错过了什么

我将非常感谢你的帮助

下面是布局文件中一个TextView小部件的定义：

 <TextView
     android:id="@+id/tv1"
     android:layout_width="wrap_content"
     android:layout_height="65dp"
     android:background="@drawable/roundedyellowbtn1"
     android:text="@string/choice1"
     android:textSize="35sp"
     android:onClick="onClick"
     android:clickable="true"
     android:layout_margin="5dp" />

你觉得有什么不对吗

以下是全部代码：

一种方法是删除文本视图，然后用相同的文本重新创建文本视图，但我相信没有删改。谢谢大家的帮助。问题是我有两个连续的简单if语句，但它们必须是 如果 否则，如果。。。。 否则

这确实很有趣，但现在它起作用了

谢谢@JRowan，但我看到了这一点，它对我来说根本不起作用。我试着一个字符一个字符地恢复文本，但我仍然能完全恢复；你试过了吗，对不起，我从来没有试过，只是想帮你一把是的，我也试过。它不起作用。我一定是错过了什么，不知道是什么>@JRowan，我真的很感谢你的帮助，但我觉得很沮丧，因为这对我不起作用。有人知道为什么吗？谢谢你的帮助，但是罢工并没有消失。我从布局文件中添加了TextView小部件的定义。我有很多这样的TextView，tv被分配了tv1、tv2、tv3等中的一个。。。然后我调用一个方法striketv。在这个方法中，我检查电视是否被删除。如果是，那么我想删除删除删除线。如果它不是，那么我就敲打它，这样就行了，我还做了一些其他的事情。方法strike是在文本视图的onClick方法中调用的。我认为您的代码中有一些有趣的地方，因为其他人已经能够使用建议的代码撤消删除。你能多发一些代码吗？代码很长，但我会尽量发的。
