我的数据库类是：
public class Database extends SQLiteOpenHelper {
private static final int DB_VERSION = 1;
private static final String DB_NAME = "databse";
public static final String TABLE_SOURCES = "sources";
public static final String ID = "_id";
public static final String COL_TITLE = "title";
public static final String COL_URL = "url";
public static final String COL_UPDATE = "update";
public static final String COL_PERIOD = "period";
private static final String CREATE_TABLE_SOURCES = "CREATE TABLE "
+ TABLE_SOURCES + " (" + ID
+ " integer PRIMARY KEY AUTOINCREMENT, " + COL_TITLE
+ " text NOT NULL ); ";
private static final String DB_SCHEMA = CREATE_TABLE_SOURCES;
public Database(Context context) {
super(context, DB_NAME, null, DB_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL(DB_SCHEMA);
Log.d("create db", "create 2 db");
seedData(db);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_SOURCES);
onCreate(db);
}
/**
* Create sample data to use
*
* @param db
* The open database
*/
private void seedData(SQLiteDatabase db) {
db.execSQL("insert into sources (title) values ('new');");
Log.d("insert to db", "insert to db 2 records");
}
// Getting contacts Count
public int getContactsCount() {
String countQuery = "SELECT * FROM " + TABLE_SOURCES;
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery(countQuery, null);
cursor.close();
// return count
return cursor.getCount();
}
}
我用它：
private Database db = new Database(this);
Toast.makeText(getApplicationContext(), String.valueOf(db.getContactsCount()),
Toast.LENGTH_LONG).show();
但我的应用程序无法运行，不幸的是，myapp 停止了。
什么问题？
