我已经为表名和入局号码创建了单独的类
DbContract.class
DbHelper。班级
public class DbHelper extends SQLiteOpenHelper {
private static final String DATABASE_NAME = "numberDb";
private static final int DATABASE_VERSION = 1;
private static final String CREATE_TABLE_INFO = "CREATE TABLE" + DbContract.TABLE_NAME +"(ID INTEGER PRIMARY KEY AUTOINCREMENT," + DbContract.INCOMING_NUMBER + ",TEXT);";
private static final String DROP_TABLE = "drop table if exists" + DbContract.TABLE_NAME;
public DbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(CREATE_TABLE_INFO);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL(DROP_TABLE);
onCreate(db);
}
public void saveNumber(String number, SQLiteDatabase database) {
ContentValues contentValues = new ContentValues();
contentValues.put(DbContract.INCOMING_NUMBER, number);
database.insert(DbContract.TABLE_NAME, null, contentValues);
}
public Cursor readNumber(SQLiteDatabase database) {
String[] projection = {"id", DbContract.INCOMING_NUMBER};
return (database.query(DbContract.TABLE_NAME, projection, null, null, null, null, null));
}
DbContract。班级
public class DbContract {
public static final String TABLE_NAME = "incoming_info";
public static final String INCOMING_NUMBER = "incoming_number";
public static final String UPDATE_UI_FILTER = "nischayvaish.com.test1.UPDATE_UI";
}
要么错误出现在DbContract中。类或DbHelper。阶级
Caused by: 安卓.database.sqlite.SQLiteException: near "TABLEincoming_info": syntax error (code 1): , while compiling: CREATE TABLEincoming_info(ID INTEGER PRIMARY KEY AUTOINCREMENT,incoming_number,TEXT)
# 1 楼答案
尝试在
CREATE TABLE之后添加空格字符private static final String CREATE_TABLE_INFO = "CREATE TABLE " + DbContract.TABLE_NAME +"(ID INTEGER PRIMARY KEY AUTOINCREMENT," + DbContract.INCOMING_NUMBER + ",TEXT);";
