                        activity.finish();
                    }
                }
            }
        }
    
        @Override
        protected void onDestroy() {
            super.onDestroy();
            //activity管理
            ActivityCollector.removeActivity(this);
        }
    }
    
    

    调用也很容易

    public class MainActivity extends BaseActivity {
        @Override
        protected void onCreate(@Nullable Bundle savedInstanceState) {
            //设置是否显示标题栏
            setShowTitle(true);
            //设置是否显示状态栏
            setShowStatusBar(true);
            //是否允许屏幕旋转
            setAllowScreenRoate(true);
            //以上设置一定要在 super.onCreate(savedInstanceState) 方法之前设置
            super.onCreate(savedInstanceState);
        }
     
        @Override
        protected int initLayout() {
            //初始化布局
            return R.layout.activity_main;
        }
     
        @Override
        protected void initView() {
            //初始化控件
            Button button = new Button(context);
            button.setText("click");
            //每秒只响应一次点击事件
            button.setOnClickListener(new OnSingleClickListener() {
                @Override
                public void onSingleClick(View view) {
     
                }
            });
            //每秒可以重复响应点击事件
            button.setOnClickListener(new OnMultiClickListener() {
                @Override
                public void onMultiClick(View view) {
     
                }
            });
        }
     
        @Override
        protected void initData() {
     
            //初始化、绑定数据
        }
     
     
    }
    

    没更新动态或者频繁更新动态的时候都是在认真生活
