приложение вышло и его трудно найти причину

Question

Я работаю над созданием приложения и помещением данных в mysql. Это было нормально, когда мой одноклассник руководил проектом в своем ноутбуке. Но это не работает в моем ноутбуке. Я пытаюсь решить проблему, но приложение все еще остановилось. я не знаю, почему ..

Вот код и журнал

    TextView Otime, Ctime; 
    String pic,name, mobile, addrs, otime, ctime, fee;// 바꾸고 이미지도 추가. 
    ImageView Pic;

Answer 1

Вы можете решить эту проблему с помощью своего MainActivity, прокрутка вплоть до части, которая говорит setContentView (R.layout. your_layout_name); и нажмите your_layout_name, удерживая Ctrl (Windows) или Cmd (Mac). Это приведет вас к вашему файлу макета. Здесь вы должны увидеть тег открытия ScrollView в начале и закрывающий тег в конце. Просто измените это на что-нибудь еще:

<?xml version="1.0" encoding="utf-8"?> 
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
       android:orientation="vertical" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent"> 
    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="vertical"> 

     <TextView 
      android:text="This is your first item" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content"/> 

     <TextView 
      android:text="This is your second item" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content"/> 

     <TextView 
      android:text="This is your third item" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content"/> 

    </LinearLayout> 

</ScrollView>
