App stoppt mit Fragmenten mit Countdown-Timer

Question

Ich bin neu in Android. Ich bewege zwei Fragmente über einen Countdown-Timer. nach 10 Sekunden sollte das nächste Fragment angezeigt werden, aber meine App funktioniert nicht mehr. Ich habe versucht, eine Lösung, aber konnte nicht dafür geeignet finden. Bitte helfen Sie mir.

Question3.java (Erste Fragment)

package com.example.sheikhspc.testapp; 


import android.app.FragmentManager; 
import android.app.FragmentTransaction; 
import android.os.Bundle; 
import android.app.Fragment; 
import android.os.CountDownTimer; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ImageView; 
import android.widget.TextView; 
import android.widget.Toast; 


public class Question3 extends Fragment { 


public Question3() { 
    // Required empty public constructor 
} 
CountDownTimer timer; 
int score; 
Fragment frag; 
TextView tv, scr; 
View view; 
ImageView imageView1, imageViewR, imageView2; 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    view = inflater.inflate(R.layout.fragment_question3, container, false); 

    tv = (TextView)view.findViewById(R.id.timer3); 
    imageView1 = (ImageView) view.findViewById(R.id.wrong1); 
    imageViewR = (ImageView) view.findViewById(R.id.right); 
    imageView2 = (ImageView) view.findViewById(R.id.wrong2); 


    timer = new CountDownTimer(10000, 1000) { 

     public void onTick(long millisUntilFinished) { 
      tv.setText("seconds remaining: " + millisUntilFinished/1000); 
      //here you can have your logic to set text to edittext 
     } 

     public void onFinish() { 
      tv.setText("done!"); 
      frag = new Question4(); 
      FragmentManager fm = getFragmentManager(); 
      FragmentTransaction fragmentTransaction = fm.beginTransaction(); 

      fragmentTransaction.replace(R.id.container, frag); 

      fragmentTransaction.commit(); 

     } 

    }; 
    timer.start(); 


    return view; 
} 

} 

Question4.java (Zweite Fragment)

package com.example.sheikhspc.testapp; 


import android.app.FragmentManager; 
import android.app.FragmentTransaction; 
import android.os.Bundle; 
import android.app.Fragment; 
import android.os.CountDownTimer; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ImageView; 
import android.widget.TextView; 


public class Question4 extends Fragment implements View.OnClickListener { 


public Question4() { 
    // Required empty public constructor 
} 
Fragment frag; 
TextView tv; 
View view1; 
CountDownTimer timer; 
ImageView imageView1, imageViewR, imageView2; 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 
    view1 = inflater.inflate(R.layout.fragment_question4, container, false); 

    tv = (TextView)view1.findViewById(R.id.timer4); 
    imageView1 = (ImageView) view1.findViewById(R.id.wrong1); 
    imageViewR = (ImageView) view1.findViewById(R.id.right); 
    imageView2 = (ImageView) view1.findViewById(R.id.wrong2); 
    imageView1.setOnClickListener(this); 
    imageViewR.setOnClickListener(this); 
    imageView2.setOnClickListener(this); 

    timer = new CountDownTimer(10000, 1000) { 

     public void onTick(long millisUntilFinished) { 
      tv.setText("seconds remaining: " + millisUntilFinished/1000); 
      //here you can have your logic to set text to edittext 
     } 

     public void onFinish() { 
      tv.setText("done!"); 
      frag = new Question5(); 
      FragmentManager fm = getFragmentManager(); 
      FragmentTransaction fragmentTransaction = fm.beginTransaction(); 

      fragmentTransaction.replace(R.id.container, frag); 

      fragmentTransaction.commit(); 

     } 

    }; 
    timer.start(); 




    return view1; 
} 

@Override 
public void onClick(View v) { 
} 
}
