Answer 1

public void fetchUserDataInBackground(User user,GetUserCallback callback){ 
    progressDialog.show(); 
    new fetchUserDataAsyncTask(user,callback).execute(); 
} 

将其更改为：

public void fetchUserDataInBackground(User user,GetUserCallback callback){ 
    if (!progressDialog.isShowing()) { 
     progressDialog.show(); 
    } 
    new fetchUserDataAsyncTask(user,callback).execute(); 
} 

Answer 2

您尝试

private ProgressDialog PD; 

    if(PD == null){ 

// 
        PD = new ProgressDialog(SplashScreenActivity.this); 
        PD.setMessage("Please Wait.."); 
        PD.setIndeterminate(false); 
        PD.setCancelable(true); 
        PD.show(); 
      } 

，你cloce PrpgressDialog

if(PD.isShowing()){ 
        PD.dismiss(); 
        goNext(); 
       }
