Android 使用导航抽屉，某些活动比其他活动更难加载

我有一个将我的活动与导航抽屉连接的应用程序。问题是，某些活动的加载比其他活动更困难（当我按下抽屉上的图标时，它不会立即打开活动，而是停留1-2秒，然后加载活动）。这可能是一个虚拟的问题，但如果你能给我一些关于如何修复它的建议，是否可能？下面是一个加载更困难的活动

public class ImportAPI extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
public TextView fullnameside, emailside;

public static String stravaToken;

public ImageButton btnStrava;
public ImageView tickStrava;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.importapi);


    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    toolbar.setTitle("");
    toolbar.setSubtitle("");

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    View headerView = navigationView.getHeaderView(0);
    fullnameside = (TextView) headerView.findViewById(R.id.fullnameside);
    emailside = (TextView) headerView.findViewById(R.id.emailside);
    fullnameside.setText(""+GetInfo.fullname);
    emailside.setText(""+GetInfo.email);

    navigationView.setNavigationItemSelectedListener(this);
    navigationView.getMenu().getItem(3).setChecked(true);


    //STRAVA
    tickStrava=(ImageView) findViewById(R.id.tickStrava);
    btnStrava=(ImageButton) findViewById(R.id.stravaBtn);
    connectStrava();

}

public void connectStrava(){

    btnStrava.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent getStravaApi= new Intent(ImportAPI.this,StravaSetupApi.class);
            startActivity(getStravaApi);

        }

    });

    //GET ACCESS TOKEN FROM STRAVAS AUTHORIZE ACCOUNT
    String accessToken = StravaAuthenticateActivity.getStravaAccessToken(this);
    stravaToken=accessToken; //make static var so i can use it anywhere i want

    //Get athletes activities from GetStravaAthleteActivities.java
    new GetStravaAthleteActivities.AthleteActivities();

    //check if token is null so i can display the tick and also disable the button press
    if(stravaToken!=null)
    {
        btnStrava.setEnabled(false);
        tickStrava.setVisibility(View.VISIBLE);
    }
    else {
        tickStrava.setVisibility(View.INVISIBLE);
    }

}

尝试检查是否是活动的故障，而不是抽屉菜单的故障。您可以对onnectStrava（）方法计时，这可能会导致延迟。在方法的开头和结尾添加日志消息

public void connectStrava(){
Log.d(“TAG”, “STRAVA Entry point);
…
Log.d(“TAG”, “STRAVA Exit point);
}

---

然后检查IDE Logcat上的时间戳，并查看该方法运行所需的时间。如果确实是1-2秒，那么您知道是什么导致延迟。如果是这种情况，您可以尝试在单独的线程上或作为异步任务启动该方法，以免该方法阻塞您的UI
