在Activity/Fragment容器中添加ObserverSSC平台架设,需要请搜索【大神源码论坛】dsluntan.com 客服企娥3393756370 V信17061863513,
public class MainActivity extends AppCompatActivity {
private IPresenter mPresenter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d("tag", "onCreate" + this.getClass().toString());
setContentView(R.layout.activity_main);
mPresenter = new MainPresenter(this);
getLifecycle().addObserver(mPresenter);//添加LifecycleObserver
}
@Override
protected void onDestroy() {
Log.d("tag", "onDestroy" + this.getClass().toString());
super.onDestroy();
}
}
如此,每当Activity发生了对应的生命周期改变,Presenter就会执行对应事件注解的方法:
除onCreate和onDestroy事件之外,Lifecycle一共提供了所有的生命周期事件,只要
通过注解进行声明,就能够使LifecycleObserver观察到对应的生命周期事件:
