android用歡迎界面加載運行環境

以前一直以為splash頁只是圖好玩..

今天才知道是應該把環境加載放在這個頁面...

論壇和github上太多仿XXX的項目果然只能學習下ui的思路...

以前把環境加載放在application裡面，難怪啟動白屏要花那麼長時間...

代碼很簡單，做一個線程，然後delay運行即可，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() {
                //初始化服務
                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");

                //界面跳轉
                String token = AppContext.getInstance().getToken();
                if (TextUtils.isEmpty(token)) {
                    startActivity(SignInActivity.newIntent());
                } else {
                    startActivity(MainActivity.newIntent());
                }
                finish();
            }
        },500);
    }

    private void initService(){
        //注冊環信通知
       AppContext.getInstance().initEnvir();
        //注冊百度定位
        AppContext.getInstance().initLocation();
    }
}
