应用停止使用倒数计时器的片段

我是Android新手。我在倒数计时器上移动两个片段。 10秒后下一个片段应该出现，但我的应用程序停止工作。我尝试了一些解决方案，但无法找到它。请帮帮我。应用停止使用倒数计时器的片段

Question3.java（第一个片段）

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（第二片段）

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) { 
} 
}

日志表明，一个OutOfMemoryError。你在片段中使用大的位图吗？如果是的话，那么一旦使用完成后，你必须回收位图变量，让gc（）清除位图占用的内存。 – EEJ

是的，我记得有一些问题。你能指导我一点，我在哪里做错了什么？ –

它显示错误在这一行的第二个片段 ** view1 = inflater.inflate（R.layout.fragment_question4，container，false）; ** 我不知道我做错了什么。同一个项目运行良好。 –

只是在AndroidManifest添加以下代码。 xml

android:largeHeap="true"

AndroidManifest.xml中

<application 
android:allowBackup="true" 
android:icon="@mipmap/guruji" 
android:label="@string/app_name" 
android:supportsRtl="true" 
android:largeHeap="true" 
android:theme="@style/AppTheme">
