Android APP前后台状态切换

Posted 2022-09-11 timipaul

getActivity().getApplication().registerActivityLifecycleCallbacks(new Application.ActivityLifecycleCallbacks() 
            @Override
            public void onActivityCreated(Activity activity, Bundle bundle) 

            

            @Override
            public void onActivityStarted(Activity activity) 
                //说明从后台回到了前台

            

            @Override
            public void onActivityResumed(Activity activity) 

            

            @Override
            public void onActivityPaused(Activity activity) 

            

            @Override
            public void onActivityStopped(Activity activity) 
　　　　　　　　//进入到后台
               

            

            @Override
            public void onActivitySaveInstanceState(Activity activity, Bundle bundle) 

            

            @Override
            public void onActivityDestroyed(Activity activity) 

            
        );

 

在要调用的Activity 中的 onCreate() 方法中使用
