Question

在MainActivity.java中，我有以下

String keyword = null;
public String getkeyword() {
        return keyword;
    }
    public void setkeyword(String keyword) {
        this.keyword = keyword;
    }

GS

keyword was declared like: public String keyword = GS.getkeyword();
endpoint was specified like: &keyword=" +  keyword

fix was: &keyword=" + MainActivity.GS.getkeyword()

我的问题是onClick执行了我想要的代码，但是它不会设置关键字。在GS类中，我将关键字声明为“ public String keyword = null;”。在method1（）中执行时，API返回null。

我想这是一个时间问题？我看过其他线程，但没有解决方案。我还有另一个活动可以调整用户设置，并且这些值会正确地通过API传递。

编辑：这就是为什么堆栈溢出具有后期质量准则的原因。我未能提供足够的信息。

使用此

private String keywword;
public String getkeyword() {
    return keyword;
}
public void setkeyword(String keyword) {
    this.keyword = keyword;
}

Android-getter / setter未传递一个特定的字符串
