我有一个包含多个片段的活动。活动最初有片段，并在它有两个按钮。在点击该按钮，我必须通过新的片段来代替片段。每个片段都有不同的部件和替换当前的片段作为各种活动。

I have an activity containing Multiple fragments. Activity initially have fragment and in it have two buttons. Upon clicking this button i have to replace the fragment by new fragment. Each fragment has various widgets and replace the current fragment as various events.

这是我的问题。我怎样才能达到这样做。

This is my problem. How can i achieve this be done.

您可以通过FragmentTransaction代替片段。

you can replace fragment by FragmentTransaction.

在这里，你走了。

请一个接口。

public interface FragmentChangeListener 
{
    public void replaceFragment(Fragment fragment); 
}

实现您的碎片保持活性，此接口。

implements your Fragment holding activity with this interface.

public class HomeScreen extends FragmentActivity implements
        FragmentChangeListener {


         @Override
         public void replaceFragment(Fragment fragment) {
            FragmentManager fragmentManager = getSupportFragmentManager();;     
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            fragmentTransaction.replace(mContainerId, fragment, fragment.toString());
            fragmentTransaction.addToBackStack(fragment.toString());
            fragmentTransaction.commit();   
    }

}

从片段调用此方法是这样的。

Call this method from Fragments like this.

//在您的片段。

public void showOtherFragment()
{
       Fragment fr=new NewDisplayingFragment();
             FragmentChangeListener fc=(FragmentChangeListener)getActivity();
             fc.replaceFragment(fr);
}

希望这将工作！

Hope this will work!

注意：mContainerId是谁拿着里面的片段视图的ID。 你应该重写片段的onString（）方法为好。

NOTE: mContainerId is id of the view who is holding the fragments inside. You should override Fragment's onString() method as well.
