Android实现EventBus登录界面与传值（粘性事件）

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）
