这段代码的奇怪之处在于运行按钮时，第一个寻呼机和第二个寻呼机中的文本值会正确更改，但当它到达第三个寻呼机时，它会在更改值时重置第一个寻呼机显示的值，但getText（）方法继承了正确的值，但文本被冻结，无法再更改，之后其他页面的值也无法更改，但getText（）方法仍然可以正常工作并获得正确的值。
任何想法都会加快我的调试过程thanx无论如何。

添加此剪切解决了问题，必须为寻呼机定义边框

@Override
protected void onCreate(Bundle savedInstanceState) {
        ...
    int size = sliderAdapter.slide_headings.length;
    AktifHareket.setOffscreenPageLimit(size);
