不幸的是应用程序已经停止
问题描述：
我试图做一个简单的Android SQLite数据库，并且在我尝试运行该应用程序后，它说“不幸的appName已停止”，然后检查我的LogCat并遇到一些错误。 这里是我的错误日志：不幸的是应用程序已经停止

这里是另一个类，这是不是我创建的名为“DatabaseManager.java”的活动类：

private static final String NAMA_TABEL = "hobiku";
private static final int DB_VERSION = 1;
private static final String CREATE_TABLE = "create table"+NAMA_TABEL+" ("+ROW_ID+" integer PRIMARY KEY autoincrement,"+ROW_NAMA+" text,"+ROW_HOBI+" text)";
private final Context context;
private DatabaseOpenHelper dbHelper;

public DatabaseManager(Context ctx) {
this.context = ctx;
dbHelper = new DatabaseOpenHelper(context);

}

onCreate(db);
}
}
public void close() {
dbHelper.close();
}
public void addRow(String nama, String hobi) {
ContentValues values = new ContentValues();
values.put(ROW_NAMA, nama);
values.put(ROW_HOBI, hobi);
try {
db.insert(NAMA_TABEL, null, values);
} catch (Exception e) {
Log.e("DB ERROR", e.toString());
e.printStackTrace();
}
}
public ArrayList<ArrayList<Object>> ambilSemuaBaris() {
ArrayList<ArrayList<Object>> dataArray = new
ArrayList<ArrayList<Object>>();
Cursor cur;
try {
cur = db.query(NAMA_TABEL,
new String[] { ROW_ID, ROW_NAMA, ROW_HOBI }, null, null,
null, null, null);
cur.moveToFirst();
if (!cur.isAfterLast()) {
do {
ArrayList<Object> dataList = new ArrayList<Object>();
dataList.add(cur.getLong(0));
dataList.add(cur.getString(1));
dataList.add(cur.getString(2));
dataArray.add(dataList);
} while (cur.moveToNext());
}
} catch (Exception e) {
// TODO Auto-generated catch block

Log.e("DEBE ERROR", e.toString());

}

答
既然你有这样的例外：
Caused by: android.database.sqlite.SQLiteException: near "tablehobiku": syntax error (code 1): , while compiling: create tablehobiku (_id integer PRIMARY KEY autoincrement,nama text,hobi text)
您的脚本不正确，必须是 “创建表hobiku”
所以，你必须添加一个空间：
"create table"+NAMA_TABEL+"
它必须be
"create table "+NAMA_TABEL+"
答
你有拼写错误。使用table hobiku而不是tablehobiku。
