今天心血来潮怀着激动的心情来给码友们甩一个小博客！！

概念、优点等什么的我就不说了网上一箩筐

废话不说了直接甩代码

1.导入依赖

compile 'org.greenrobot:eventbus:3.0.0'


主页面发送消息：
public class MainActivity extends AppCompatActivity {    private EditText etName;    private EditText etPwd;    private Button butLogin;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        butLogin = (Button) findViewById(R.id.butLogin);        etName = (EditText) findViewById(R.id.etName);        etPwd = (EditText) findViewById(R.id.etPwd);        butLogin.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                String name = etName.getText().toString();                String pwd  = etPwd.getText().toString();                Toast.makeText(MainActivity.this,name+pwd,Toast.LENGTH_SHORT).show();                EventBus.getDefault().postSticky(new MyData(name,pwd));                Intent in = new Intent(MainActivity.this,Main2Activity.class);                startActivity(in);            }        });    }    @Override    protected void onDestroy() {        super.onDestroy();        EventBus.getDefault().unregister(this);    }}

第二个页面接收消息（注意：在哪里接收消息就得在哪里注册）

EventBus.getDefault().register(this);

public class Main2Activity extends AppCompatActivity {    String sName,sPwd;    TextView name,pwd;    Button button;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main2);        //注册        EventBus.getDefault().register(this);        button = (Button) findViewById(R.id.but);        name = (TextView) findViewById(R.id.tvName);        pwd  = (TextView) findViewById(R.id.tvPwd);        button.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                name.setText(sName);                pwd.setText(sPwd);            }        });            }    //接收消息    @Subscribe(threadMode = ThreadMode.MAIN,sticky = true)    public void onEventMainThread(MyData data){        sName = data.getsName();        sPwd = data.getsPwd();        Log.d("data","====" + sName + sPwd);    }}

这是我的参数事件类

public class MyData {    private String name;    private String pwd;    public MyData(String sName,String sPwd) {        name = sName;        pwd  = sPwd;    }    public String getsName() {        return name;    }    public String getsPwd() {        return pwd;    }}
