通过反射发送通知事件,传递数据
##添加依赖
compile 'com.canyinghao:canbus:1.0.0'
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); } }
