Now in all frament i had declare two or three edittext now in this activity, i want to get data from that all edittext from diffrent frangment tab.

推荐答案

一个单独的类可以帮助您解决问题。

A singleton class could help solve your problem.

public class GlobalApp {
    private static GlobalApp instance = new GlobalApp();

    private GlobalApp() {}

    public static GlobalApp getInstance() {
        return instance;
    }

    public Details details = new Details ();

}

那么在这样的片段类中使用。

Then use in your Fragment class like this..

GlobalApp.getInstance().details.setSomeData("something");

现在，你可以得到所有这一切都在这些片段在mainActivity修改的数值

Now you can get all the values which are changed in those fragment in your mainActivity

 GlobalApp.getInstance().details.getSomeData();

我已经给了另外一个问题，其中有一些关于这相同的答案。

I have given the same answer for another question which has some relation to this.
