以前一直以为splash页只是图好玩..

今天才知道是应该把环境加载放在这个页面...

论坛和github上太多仿XXX的项目果然只能学习下ui的思路...

以前把环境加载放在application里面，难怪启动白屏要花那么长时间...

代码很简单，做一个线程，然后delay运行即可，如下：

public class SplashActvity extends AbstractActivity {    private static final int sleepTime =4000;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_splash);        new Handler().postDelayed(new Runnable() {            @Override            public void run() {                //初始化服务                long start = System.currentTimeMillis();                initService();                long costTime = System.currentTimeMillis() - start;                if (sleepTime - costTime > 0) {                    try {                        Thread.sleep(sleepTime - costTime);                    } catch (InterruptedException e) {                        e.printStackTrace();                    }                }                Log.d("splah act-------->","inited service");                //界面跳转                String token = AppContext.getInstance().getToken();                if (TextUtils.isEmpty(token)) {                    startActivity(SignInActivity.newIntent());                } else {                    startActivity(MainActivity.newIntent());                }                finish();            }        },500);    }    private void initService(){        //注册环信通知       AppContext.getInstance().initEnvir();        //注册百度定位        AppContext.getInstance().initLocation();    }}
