이클립스에서 sqlite 데이터베이스 만들기

Question

현재 이클립스에서 데이터베이스를 만들려고합니다. 사용자는 이름을 입력하고 데이터베이스에 저장할 수 있습니다. 그 외에도 저장 데이터가 다음 페이지에 표시됩니다.

오류가 발생하여 코드가 정확한지 확실하지 않습니다. 여기에서 도움을 얻었다 :

<?xml version="1.0" encoding="utf-8"?> 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" > 

<TextView 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="Enter your name below:" 
/> 

<EditText 
android:id="@+id/nameText" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
/> 

<Button 
android:id="@+id/saveButton" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:text="Save" 
/> 

</LinearLayout>

희망 모두 내가 그 문제를 해결하고 내가 작성한 모든 오류를 지적하도록 도울 수있다. 감사합니다. onCreate() 메소드의 SaveData에

Answer 1

이 있으면 database.execSQL (DATABASE_TABLE_1)이 아닙니다. 하지만 database.execSQL (CREATE_DATABASE_TABLE_1);
