我有一个启动画面（活动），它运行测试以查看用户是否有会话。如果没有，则打开LoginActivity。
我认为这可能是我的RecyclerView的一个问题。我无法解决它。我希望你能帮助我。 THX。
修改
SessionManager：
public void checkLogin(){
// Check login status
if(!this.isLoggedIn()){
// user is not logged in redirect him to Login Activity
Intent i = new Intent(_context, LoginActivity.class);
// Closing all the Activities
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
// Add new Flag to start new Activity
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
// Starting Login Activity
_context.startActivity(i);
} else {
Intent i = new Intent(_context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
_context.startActivity(i);
}
}
public boolean isLoggedIn(){
return pref.getBoolean(IS_LOGGED, false);

试试这个，这可能有效。
<强>更新
mRecyclerView = new RecyclerView(this);
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
我在您的代码中看到了这一行，您不需要两次初始化回收站视图。当您使用findViewById时，您将获得RecyclerView的对象，因此new RecyclerView(this);不是必需的，在这种情况下无用。
更新2
我怀疑你再次在checkLogin方法中启动MainActivity，这是一种错误的方法，而不是你可以直接返回布尔值。
例如：
@Override
protected void onCreate(Bundle savedInstanceState) {
boolean isSessionExist = sessionManager.isLoggedIn();
if(isSessionExist){
//open home screen
}else{
//open login screen
}
}
<强> isLoggedIn
public boolean isLoggedIn(){
return pref.getBoolean(IS_LOGGED, false);
}
}
