如何将textView更改为@string并进行提升-HowtochangetextViewtoa@stringandraising

so what i am tring to do is, i am having a book like-app, and want to setup a button when click it change the textview to a string in the @string rec. but in a different way

所以我要做的是,我有一本类似app的书,并且想要在点击它时设置一个按钮,将textview更改为@string rec中的字符串。但以不同的方式

i will put the code just a moment, lets say i have a string in @string that is NH1,NH2,NH3 i can do for button View.setText(R.string.NH1); that will work but i want to create a counter and make it so every time clicked counter++ and want it to be like this View.setText(R.string.NH+counter); if you know what i mean so each time it clicked to goes to next @string without changing layout every time and without an array because the paragraph are very long

我会把代码放一会儿,假设我在@string中有一个字符串,即NH1,NH2,NH3,我可以为按钮View.setText(R.string.NH1);这将工作,但我想创建一个计数器,使每次点击计数器++,并希望它像这样的View.setText(R.string.NH +计数器);如果你知道我的意思所以每次点击进入下一个@string而不是每次更改布局而没有数组因为段落很长

also if i have NH1-10 and the counter did not stop and still goes on what will i do. if you are sill here thank you for reading.

如果我有NH1-10并且计数器没有停止仍然继续我将做什么。如果你在这里谢谢你的阅读。
