我是Android开发的新手,现在我的启动器活动只显示5秒,之后我想检查用户是否登录或没有功能并执行操作.

这是我的代码.

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

exactPreferences = getSharedPreferences("ExactPreference",MODE_PRIVATE);

setContentView(R.layout.activity_landing_page);

session = exactPreferences.getString(Model.getSingleton().SHARED_SESSION_ID,null);

Log.i("Session Id",session);

displayData(); // I want to perform this function after 5 seconds.

}

private void displayData() {

if(session.equals("")){

Intent loginIntent = new Intent(LandingPage.this,

LoginActivity.class);

startActivity(loginIntent);

Log.i("User Logged In", "False");

}

else

{

Intent objIntent = new Intent(LandingPage.this,

IndexPageActivity.class);

startActivity(objIntent);

Log.i("User Logged In", "True");

}

}
