EventBus

一,MainActivity

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";
    private Button button;
    private TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        EventBus.getDefault().postSticky(new Preson("sdada","dfs"));
        //注册
        EventBus.getDefault().register(this);
      initView();
    }

    private void initView() {
        button = findViewById(R.id.main_btn);
        textView = findViewById(R.id.main_texr);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(MainActivity.this,Main2Activity.class);
                startActivity(intent);
            }
        });

    }

    @Subscribe(threadMode =  ThreadMode.POSTING,sticky = true)
    public void revyvlervePerson(Preson preson){
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        Log.d(TAG, "revyvlervePerson: +"+Thread.currentThread().getName()+preson.getName()+"    "+preson.getAge());
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        EventBus.getDefault().unregister(this);
    }
}

二，Main2Activity

public class Main2Activity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);

    }

    public void fasong(View view) {
        EventBus.getDefault().post(new Preson("name","20"));
    }
}

三,Person

public class Preson {
    private String name;
    private String age;

    @Override
    public String toString() {
        return "Preson{" +
                "name='" + name + '\'' +
                ", age='" + age + '\'' +
                '}';
    }

    public String getName() {
        return name;
    }

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

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public Preson(String name, String age) {
        this.name = name;
        this.age = age;
    }
}
