CanBus

通过反射发送通知事件，传递数据

##添加依赖

compile 'com.canyinghao:canbus:1.0.1'

使用方式

1.发送通知，传递参数
接收通知，需要先注册，在不需要使用时注销，然后在onCanBus方法中处理事件及参数。发送的参数类型需与接受的类型保持一致。在线程中发送通知，接收也会在主线程中处理。onCanBus方法始终在主线程中，需注意。

public class MainActivity extends AppCompatActivity {

    int num;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                num++;
                CanBus.getDefault().post("canbus post num " + num);
                Snackbar.make(view, "CanBus.getDefault().post(canbus post num " + num + ")", Snackbar.LENGTH_SHORT)
                        .setAction("Action", null).show();
            }
        });

        CanBus.getDefault().register(this);


    }


    public void onCanBus(String str){

        ((TextView)findViewById(R.id.tv_1)).setText(str);
        ((TextView)findViewById(R.id.tv_2)).setText(str);

    }



    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        CanBus.getDefault().unregister(this);
    }
}
