Öncelikle teşekkür ederim ,
Daha önce bi çok kez face detection ile ilgili soru sordum fakat pek konuya pek hakim olanın bulunmadığını farkettim.

[/code] burada yüz algılanmasını yapmaya çalışıyorum ve left, right,top,bottom gibi yüzle ilgili değerler alıp, yüzü kare içine alıyorum.
[code]
public class addDatabase extends Activity {
Button save;
EditText name;
public Database dtBase;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.add_database);
save = (Button) findViewById(R.id.save);
name = (EditText) findViewById(R.id.name);
dtBase = new Database(this);
save.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
ContentValues value = new ContentValues();
value.put("userName", name.getText().toString());
value.put("left", MainActivity.left);
value.put("right", MainActivity.right);
value.put("bottom", MainActivity.bottom);
value.put("top", MainActivity.top);
dtBase.Add(dtBase, dtBase.TableName_Face, value);
System.err.println(name.getText().toString());
System.err.println(MainActivity.left);
System.err.println(MainActivity.right);
System.err.println(MainActivity.top);
System.err.println(MainActivity.bottom);
Intent s = new Intent(addDatabase.this, MainActivity.class);
startActivity(s);
}
});
}
}
[/code] ikinci kısımda ise database e ekleme yapmak için bi ekranım var o ekranda isim yazıp değerleri o isme karşılık kaydetme yapıyorum.
[code]
public class Database extends SQLiteOpenHelper {
private static String Kayıt = "DataBase";
public String TableName_Face = "ibrahim";
private static int Version = 1;
public Database(Context context) {
super(context, Kayıt, null, Version);
// TODO Auto-generated constructor stub
}
@Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
String FaceSql = "CREATE TABLE "
+ TableName_Face
+ "(faceId INTEGER PRIMARY KEY AUTOINCREMENT, userName VARCHAR , left Integer, right Integer, bottom Integer, top Integer"
+ ")";
db.execSQL(FaceSql);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub
db.execSQL("DROP TABLE IF EXISTS" + TableName_Face);
}
public void Add(Database database, String tableName, ContentValues params) {
SQLiteDatabase SqlLite = database.getWritableDatabase();
SqlLite.insert(tableName, null, params);
Log.e("Benden selam olsun", "eklendi");
}
public Cursor readAllData(Database database, String tableName, String[] array){
Cursor cursor ;
SQLiteDatabase SqlLite= database.getReadableDatabase();
cursor= SqlLite.query(tableName, array, null, null, null, null, null);
return cursor;
}
}
[/code]son kısımda ise database olaylarını yapmaya çalışıyorum kodum tam olarak böyle.
Veri tabanına ekleme yapıyor ancak dediğim gibi sadece ilk değeri geri getiriyor.
Bu konuda bana yardımcı olabilirseniz sevinirim.
