SQL 데이터베이스에 Edittext 입력을 저장하는 방법은 무엇입니까?

Question

사용자를 SQL 데이터베이스에 저장하지만 OnClick 이벤트에서 코드를 구현하는 방법을 파악할 수없는 Android TODO 목록 앱을 작성합니다. 여기

내가 그렇게하지 않으면 내 사용자가 입력 한 데이터

public class TaskContract { 
public static final String DB_NAME = "com.aziflaj.todolist.db"; 
public static final int DB_VERSION = 1; 

public class TaskEntry implements BaseColumns { 
    public static final String TABLE = "tasks"; 
    public static final String COL_TASK_TITLE = "title"; 
    public static final String COL_TASK_DESCRIPTION = "Description"; 
    public static final String COL_TASK_DATE = "date"; 
    public static final String COL_TASK_TIME = "time"; 
}} 

SQLDbHelper 코드

public class TaskDbHelper extends SQLiteOpenHelper { 

public TaskDbHelper(Context context) { 
    super(context, TaskContract.DB_NAME, null, TaskContract.DB_VERSION); 
} 

@Override 
public void onCreate(SQLiteDatabase db) { 
    String createTable = "CREATE TABLE " + TaskContract.TaskEntry.TABLE + " (" + 
      TaskContract.TaskEntry._ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + 
      TaskContract.TaskEntry.COL_TASK_TITLE + " TEXT NOT NULL," + 
      TaskContract.TaskEntry.COL_TASK_DATE + "TEXT NOT NULL," + 
      TaskContract.TaskEntry.COL_TASK_DESCRIPTION + "TEXT NOT NULL," + 
      TaskContract.TaskEntry.COL_TASK_TIME + "TEXT NOT NULL;)"; 

    db.execSQL(createTable); 
} 

@Override 
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
    db.execSQL("DROP TABLE IF EXISTS " + TaskContract.TaskEntry.TABLE); 
    onCreate(db); 
}}

을 저장할 SQL 데이터베이스 코드 SQLiteOpenHelper를 확장 한 클래스에 값을 전달해야합니다. 예를 들면 다음과 같습니다 (This has my 구현은 현재, 그래서 당신은 테이블에 물건을 추가하거나 당신이 그것을해야하는 경우 삭제할 수 있습니다 방법에게 필요한 것, 필드 따라) 거기에서

public class UserDatabase extends SQLiteOpenHelper { 
    public static final int database_version = 1; 


    public UserDatabase(Context context) { 
     super(context, TableInfo.DATABASE_NAME, null, database_version); 
    } 

    @Override 
    public void onCreate(SQLiteDatabase sdb) { 
      String CREATE_USER_TABLE_QUERY = "CREATE TABLE IF NOT EXISTS" + TableInfo.TALBE_NAME + "("+ TableInfo.USER_NAME + " TEXT," + TableInfo.USER_PASSWORD + " TEXT," + TableInfo.USER_AUTOLOGIN + " TEXT, " + TableInfo.SESSION_ID + " TEXT, " + TableInfo.SERVER_NAME + " TEXT);"; 
      sdb.execSQL(CREATE_USER_TABLE_QUERY); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
      //This can be used if you'd like, it's not necessary though 
    } 

을 변경합니다. 다만하여 테이블에 추가 한 후

EditText item = (EditText) findViewById(R.id.item); 
String itemText = item.getText().toString(); 

그리고 : 단지와 편집 텍스트에서 텍스트를 얻을, 당신이 얻을하는 데 필요한 코드가 활동에서

public void putDataInUserTable(UserDatabase dop, String name, String pass, String autologin, String sessionId, String server) { 
    SQLiteDatabase sql = dop.getWritableDatabase(); 
    ContentValues cv = new ContentValues(); 
    cv.put(TableInfo.USER_NAME, name); 
    cv.put(TableInfo.USER_PASSWORD, pass); 
    cv.put(TableInfo.USER_AUTOLOGIN, autologin); 
    cv.put(TableInfo.SESSION_ID, sessionId); 
    cv.put(TableInfo.SERVER_NAME, server); 
    long k = sql.insert(TableInfo.TALBE_NAME, null, cv); 
} 

: 같은 것을 사용 예 :

UserDatabase db = new UserDatabase(getApplicationContext()); 
db.putDataInUserTable(*all the parameters);
