本文实例为大家分享了Android实现EventBus登录界面与传值的具体代码，供大家参考，具体内容如下

展示效果

添加EventBus导入依赖

compile 'org.greenrobot:eventbus:3.0.0'

主MainActivity方法

public class MainActivity extends AppCompatActivity { private EditText username,password; private Button btn_go; private List mdata; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mdata=new ArrayList(); username=(EditText)findViewById(R.id.username); password=(EditText)findViewById(R.id.passwork); btn_go=(Button)findViewById(R.id.btn_go); btn_go.setText("登录"); btn_go.setOnClickListener(new View.OnClickListener() {  @Override  public void onClick(View view) {  String name = username.getText().toString().trim();  String pass = password.getText().toString().trim();  EventBus.getDefault().postSticky(new UserEvent(name,pass));  startActivity(new Intent(MainActivity.this,MainBctivity.class));  } }); }}

主MainBctivity方法

public class MainBctivity extends AppCompatActivity { private Button btn_shou; private TextView tv_b; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main_bctivity); btn_shou=(Button)findViewById(R.id.btn_shou); btn_shou.setText("接受参数"); btn_shou.setOnClickListener(new View.OnClickListener() {  @Override  public void onClick(View view) {  if(!EventBus.getDefault().isRegistered(MainBctivity.this)){   EventBus.getDefault().register(MainBctivity.this);  }else{   Toast.makeText(MainBctivity.this, "请勿重复注册事件", Toast.LENGTH_SHORT).show();  }  } }); tv_b=(TextView)findViewById(R.id.tv_b); tv_b.setText("账号多少呢！"); } @Override protected void onDestroy() { super.onDestroy(); EventBus.getDefault().unregister(MainBctivity.this); } @Subscribe(threadMode = ThreadMode.POSTING,sticky = true) public void onMoonEvent(UserEvent userevent){ tv_b.setText("账号："+userevent.getUsername()+"密码："+userevent.getPasswork()); }}

UserEvent（事件类）

public class UserEvent { private String username; private String passwork; public UserEvent(String username, String passwork) { this.username = username; this.passwork = passwork; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPasswork() { return passwork; } public void setPasswork(String passwork) { this.passwork = passwork; } public UserEvent() { } @Override public String toString() { return "UserEvent{" +  "username='" + username + '\'' +  ", passwork='" + passwork + '\'' +  '}'; }}

activity_main（MainActivity的布局）

activity_main_bctivity（MainBctivity的布局）
