Otto快速使用

引入 otto

 compile 'com.squareup:otto:1.3.8'

1、创建AppBus单例，提高效率

package tsou.cn.ottotest;

import com.squareup.otto.Bus;

/**
 * Created by 黄家三少 on 2017/12/12.
 */

public class AppBus extends Bus {

    private static AppBus bus;

    private AppBus() {
    }

    public static AppBus getInstance() {
        if (bus == null) {
            bus = new AppBus();
        }
        return bus;
    }
}

2、创建数据类（因为otto没有EventBus的tag标记功能）

package tsou.cn.ottotest.ottobean;

/**
 * Created by Administrator on 2017/12/13 0013.
 */

public class PlusOneText {
    public PlusOneText(String name) {
        this.name = name;
    }

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

3、在数据接收页面—订阅，取消订阅，接收数据

  AppBus.getInstance().register(this);

  AppBus.getInstance().unregister(this);

    @Subscribe
    public void showToast(OttoBean ottoBean) {
        Toast.makeText(getContext(), ottoBean.getName() + ",===" + ottoBean.getAge(), Toast.LENGTH_LONG).show();
//        mText.setText(ottoBean.getName());
    }

    @Subscribe
    public void setContext(PlusOneText plusOneText) {
        mText.setText(plusOneText.getName());
    }

4、在数据传送的地方—发送数据

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button_one:
                OttoBean ottoBean = new OttoBean();
                ottoBean.setName("黄晓果");
                ottoBean.setAge(25);
                AppBus.getInstance().post(ottoBean);
                finish();
                break;
            case R.id.button_two:
                AppBus.getInstance().post(new PlusOneText("huangxiaoguo"));
                finish();
                break;
        }
    }
