单击我的菜单过滤器（在MainActivity中排序）时，从MainActivity获取“片段确认”

时间：2019-06-25 11:27:33

标签： android

我在MainActivity中有一个菜单项是filter（sort），我希望如果用户单击A-z或z-a之类的过滤器菜单，在我的MainActivity的onclick中它也被单击了，但是我也想在片段中得到确认 [nhewuhfduehiuhuewhucuewcueucueuncnecineincincincinneincineinciniencineicnnecnnecneicniencnnecncncncnicncincincncnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnncnciciciicicicicicicicnnnncncicncn

您可以使用EventBus或Interface来执行此操作。您可以为EventBus执行以下步骤。

实施EventBus 

implementation 'org.greenrobot:eventbus:3.1.1'

EventBustDataEvents.class 

public class EventBusDataEvents{
    public static class isClick {
        boolean isClick;

        public isClick(boolean isClick) {
            this.isClick = isClick;
        }

        public boolean getIsClick() {
            return isClick;
        }

        public void setIsClick(boolean isClick) {
            this.isClick = isClick;
        }
    }
}

MainActivity.class 

EventBus.getDefault().postSticky(new EventBusDataEvents.isClick(true));

Fragment.class 

@Subscribe(sticky = true, threadMode = ThreadMode.MAIN)
    public void isClick(EventBusDataEvents.isClick click) {
        if (click.isClick()) {

        }
    }

@Override
public void onStart() {
    super.onStart();
    try {
        EventBus.getDefault().register(this);
    } catch (Exception e) {
    }
}

@Override
public void onDestroy() {
    super.onDestroy();
    try {
        EventBus.getDefault().unregister(this);
    } catch (Exception e) {
    }
}

或界面

IMainActivity.class //接口类

public interface IMainActivity {
void onClick();}

MainActivity.class 

private IMainActivity listener; //This will be described above as a field.

     public void setOnEventListener(IMainActivity listener) {
            IMainActivity = listener;
        }

//buttonClickEvent
listener.OnClick();

Fragment.class 

//onCreateView
    setOnEventListener(new IMainActivity() {
            @Override
            public void onClick() {

            }
        });
