推荐答案

我已经解决了我的问题atlast。我加的方法present以下线在我的其他类。所以，现在当方法被调用时，我的TextView自动改变其文本。

I have solved my problem atlast. I added the below line in the method present in my other class. So now when the method is called, my textView changes its text automatically.

mymainActivity.textView_name.setText((new myCurrentclass_Name(this.context_name)).some_array[value]);

这是我被允许改变我的TextView的，我在我的MainActivity的文本。

This is how I was allowed to change the text of my TextView which I had in my MainActivity.
